Abstract

Abelmoschus manihot (L.) Medicus (AM), commonly known as Huangshukui in China, is a traditional medicinal herb. Its flowers serve as the primary active component of Huangkui Capsule (HKC), which has demonstrated therapeutic potential in various conditions such as chronic kidney disease (CKD), inflammatory bowel disease (IBD), ischemic cardiac/cerebral injuries, hepatic injury, and diabetes mellitus. In order to reveal that AM has extensive clinical applications and significant development value, this paper collates the pharmacological effects of AM and the clinical data of traditional Chinese medicine (TCM) formulations containing AM. This review aims to systematically summarize the pharmacological effects and clinical applications of AM, with a focus on its underlying mechanisms—including immunomodulation, antifibrotic activity, metabolic regulation, intestinal flora modulation, organ protection, antioxidant effects, and analgesia. Although most clinical data currently center on HKC, this article also examines other TCM formulations containing AM, such as Jiahua Tablets, Chuangling Liquid, Huangkui Lianchang Decoction, Huangkui Siwu Formula, Yu Kui Qing, Qikui Granules, Huangshukui paste, and Er Huang Ointment. By consolidating current evidence on the pharmacology and clinical use of AM, this review highlights its broad therapeutic potential and promote further research and development of AM-based treatments.

1 Introduction

Abelmoschus manihot (L.) Medicus (AM), known as Huangshukui in Chinese, is a versatile herbaceous plant of the Malvaceae family (Abelmoschus genus) with significant medicinal and edible value (Hong et al., 2021). Its therapeutic importance is well-established both in history and in modern medicine. Ancient Chinese medical books, such as Jiayou Materia Medica and the Compendium of Materia Medica, document AM’s use for treating conditions like carbuncles, toxic swellings, and scalds (Liu et al., 2023; Xue et al., 2023). The 2020 edition of the Pharmacopoeia of the People’s Republic of China (Chinese Pharmacopoeia) formally recognizes the AM flower for clearance of dampness and heat from the body, diminishing swelling, and eliminating toxins (Luan et al., 2020). Beyond China, AM (also known as Aibika or Sunset Muskmallow) is widely used in countries including India, Nepal, Papua New Guinea, Vanuatu, Fiji, and New Caledonia for various medicinal purposes. In these regions, its applications range from using crushed seeds to relieve pain and foot spasms, as well as to manage lactation or menorrhagia, to the practice of applying root juice for sprains (Todarwal et al., 2011; Zhong et al., 2024).

Although the dried flower is the primary part used in medicine, other plant components—such as the seeds, roots, stems, and leaves—are also utilized to address conditions like indigestion, poor appetite, and traumatic injuries (Yin et al., 2021). Phytochemical studies have identified diverse constituents in AM, such as flavonoids, polysaccharides, steroids, volatile oils, and amino acids (Liu et al., 2016; Guo et al., 2021; Xue et al., 2023). Modern pharmacological research validates and expands upon traditional uses, revealing that AM possesses various bioactivities, including antimicrobial, antioxidant, analgesic, and anti-inflammatory properties. These mechanisms contribute to the treatment of various ailments, such as the amelioration of inflammatory bowel disease (IBD), restoration of heart and brain damage, improvement of renal and liver function, and regulation of intestinal flora and glucose/lipid metabolism (Ding et al., 2013; Zhang et al., 2017; Zhu et al., 2018; Luan et al., 2020; Gao et al., 2022; Zhou et al., 2022; Wei et al., 2023; Miao et al., 2024b; Song et al., 2024; Xu et al., 2024; Zhang et al., 2024; Wen and Chen, 2017; Zhou and Chen, 2016).

The most widespread application of AM in clinical practice is Huangkui Capsule (HKC), a single-herb traditional Chinese medicine (TCM) preparation derived from AM, approved for treating chronic kidney disease (CKD) and rheumatoid arthritis by the National Medical Products Administration of China (Luan et al., 2020; Wei et al., 2023). HKC is also commonly prescribed for conditions including primary chronic glomerulonephritis, nephrotic syndrome (NS), diabetic nephropathy (DN), hepatitis B-associated glomerulonephritis, and chronic renal failure (Luan et al., 2020; Wei et al., 2023). Similarly, Huangkui Lianchang decoction (HLD), formulated with AM as the principal ingredient, has shown efficacy in alleviating ulcerative colitis (UC) (Xu et al., 2024). Other AM-containing prescriptions—such as Jiahua Tablets, Chuangling Liquid, Huangkui Siwu Formula, Yu Kui Qing, Qikui Granules, Huangshu Kuihua paste, and Er Huang Ointment—have demonstrated therapeutic effects on CKD, skin ulcers, and chronic inflammatory diseases (Guo and Wang, 2017; Yan et al., 2018; Lu T. et al., 2020). This review synthesizes current reports on the ethnobotany, phytochemistry and their bioactive properties, pharmacological activities, and potential mechanisms of AM and its formulations. It also highlights limitations in existing research and discusses prospects for future applications, underscoring AM’s potential to bridge traditional and modern medicine.

3 Plant ethnobotany and distribution

Abelmoschus manihot (L.) Medicus (AM) is an annual or perennial robust, erect herb with vigorous growth of aboveground parts and a plant height of 1–2 m (Figure 2A). The root of AM is slightly conical, with many lateral roots (Shao, 2012). AM leaves are palmately divided and have irregular, coarsely toothed margins. The flower is divided into five petals; the periphery is yellowish or pale yellow, and the center is purplish. The flower diameter is 10–20 cm, flowering from bottom to top, and the ovary is 5-chambered (Figure 2B). The plant flowers from August to October and is considered highly ornamental value (Chen et al., 2016). The capsule is oblong, pointed, and hirsute, 5.0–7.5 cm long, and contains about 50 seeds per capsule. At maturity, the seeds are gray-black and kidney-shaped, with many stripes on the surface.

(C) AM is native to provinces in China including Hebei, Shandong, Henan, Hubei, Hunan, Hainan, Guizhou, Guangxi, Guangdong, Jiangsu, Zhejiang, and Fujian, which are marked with slashes in figure. (D) AM is distributed in China, India, Nepal, Papua New Guinea, Vanuatu, Fiji, New Caledonia, Sri Lanka, and North Queensland.

AM originated in the southern part of China. It prefers to be grown in warm and humid weather with abundant rainfall and adequate sunshine in good drainage and loose, fertile soil. However, it is adaptable and now is widely distributed in tropical and subtropical regions. The natural distribution of AM in China is mainly concentrated in plain areas, such as Hebei, Henan, Shandong, and Fujian (Figure 2C). AM is also distributed in India, Sri Lanka, North Queensland, and other countries (Figure 2D).

4 Phytochemistry and their bioactive properties

Chemical investigations have revealed that different parts of A. manihot (L.) Medicus (AM) contain distinct chemical components. The flowers are primarily rich in flavonoids, while the seeds are abundant in amino acids and unsaturated fatty acids. The roots, stems, and leaves mainly contain polysaccharides (Li Z. et al., 2016). While the chemical composition of AM has been well-studied, research into the pharmacological effects of its main components is still in the early stages.

4.1 Flavonoids

Flavonoids represent the primary chemical constituents and the most significant bioactive components of AM. Forty-eight flavonoids have been isolated and identified from AM flowers. These compounds can be broadly categorized into four groups: 1) Quercetin and its glycoside derivatives, including quercetin, rutin, hyperoside, quercetin-3′-O-β-D-glucoside, quercetin-3-O-β-D-glucoside, quercetin-3-O-β-D-6′-acetylglucopyranoside, quercetin-3-O-β-robinobioside, quercetin-3-O-β-rutinoside, and quercetin-3-O-β-D-xylopyranosyl (1→2)-β-D-galactopyranoside; 2) Gossypetin and its glycoside derivatives, such as gossypetin, hibifolin, and gossypetin-3′-O-β-D-glucoside; 3) Myricetin and its glycoside derivatives, exemplified by myricetin, myricetin-3-O-β-D-glucoside, cannabiscitrin, myricetin-3-O-β-D-galactopyranoside, myricetin-3-O-rutinoside, myricetin-3-O-robinobioside, and myricetin-3-O-β-D-xylopyranosyl-(1→2)-β-D-glucopyranoside; 4) Other flavonoid compounds, such as tiliroside, hibiscetin-3-O-glucoside, floramanoside B, floramanoside C, and 5-hydroxy-4′,7,8-trimethoxyflavone. Based on current literature, Table 1 summarizes the pharmacological effects and associated mechanisms of action for key representative flavonoid constituents of AM, including: hyperoside, quercetin, isoquercitrin, gossypetin-3′-O-β-D-glucoside, quercetin-3′-O-β-D-glucoside, gossypetin-8-O-β-D-glucuronide, myricetin-3-O-β-D-galactopyranoside, and abelmanihotols A-C.

4.2 Polysaccharides

AM flowers, roots, stems, and leaves are rich in soluble polysaccharides. Notably, the total polysaccharide content in the stems can reach as high as 10.86% (Li et al., 2025). Recent studies have confirmed that AM polysaccharides possess skincare, immunomodulatory, and anti-tumor activities (Liu et al., 2016; Pan et al., 2018; Wang J. et al., 2024). Specific polysaccharide fractions—such as AMPS-a, KSK-JT, S-SLAMP-a3, SLAMP-c, and SLAMP-d—contribute significantly to these immunomodulatory and anti-tumor activities (Table 1).

4.3 Other compounds

A total of 22 amino acids and 16 nucleosides have been identified in AM. Among these, the amino acid content is higher in the flowers, reaching 4.737 mg/g, while nucleoside levels in the leaves are relatively lower at 1.474 mg/g (Liu et al., 2016). Leaf composition analysis reveals 1.77% lipids, 2.20% protein, 1.61% ash, and 88.4% moisture. Steroids and triterpenoids have also been detected in AM stems (Wen et al., 2015).

AM seeds are rich in fatty acids, soluble polysaccharides, soluble proteins, amino acids, nucleosides, and mineral elements (Liu et al., 2012; Wen et al., 2015). Total fatty acids constitute 10.22% of seed composition, with unsaturated fatty acids accounting for 78.01%–79.40% of this fraction (Liu et al., 2016). Amino acids are abundant (10.08%–10.15%), and essential amino acids represent 38.42%–39.40% of total free amino acids (Liu et al., 2016). Nucleoside content is relatively low (3.01–3.11 mg/g) (Liu et al., 2016). AM seeds also contain a diverse profile of 24 mineral elements—including K, Ca, Fe, Mn, Cu, Zn, and Mo—with levels of harmful elements (Hg, As, Cd) below food hygiene standards (Wen et al., 2015). Studies report that unsaturated fatty acids from AM seeds reduce serum levels of total cholesterol (TC), triglycerides (TG), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in hyperlipidemic rats, while increasing high-density lipoprotein (HDL) (Wu, 2011). These findings demonstrate the significant nutritional and medicinal value of AM seeds.

5 Pharmacological activities of AM

Abelmoschus manihot (L.) Medicus (AM), particularly its flowers, exhibits therapeutic potential against various diseases including CKD, IBD, ischemic cardiac/cerebral injuries, hepatic injury, and diabetes mellitus (Figure 3). Advances in research methodologies have enabled systematic investigation into the pharmacological activities of AM. This section summarizes the established pharmacology and underlying mechanisms of AM and HKC (Table 2; Figure 4).

FIGURE 4

Flowchart illustrating the mechanisms of Abelmoschus Manihot and Huangkui Capsule in organ protection, anti-inflammatory effects, and metabolic regulation. It includes pathways like NOX, ERK1/2, JAK2, and AMPK, highlighting outcomes such as renal protection and inflammatory response modulation.

Potential mechanisms of AM or HKC in disease treatment, created with BioRender.com. This figure summarizes the multi-target mechanisms of AM in organ protection, anti-inflammatory effects, and metabolic regulation. The mechanisms include: organ protection via inhibiting renal tubulointerstitial fibrosis by regulating the NOX/ROS/ERK pathway (e.g., α-SMA, E-cadherin), reducing podocyte apoptosis through JAK2/STAT3, suppressing mesangial cell generation via TGFβ/IGF-1, and alleviating renal tubular cell injury through the ERK1/2/caspase pathway and NLRP3/GSDME; anti-inflammatory effects by suppressing inflammatory activity through p38 MAPK/TGFβ/Smad3, decreasing pro-inflammatory cytokine release via iRhom2/TACE/XBP1S, regulating macrophage polarization via AMPK/SIRT1, and inhibiting monocyte adhesion through TLR4/NFκB and β-arrestin1/NLRP3; as well as metabolic regulation through ameliorating lipid accumulation via the SCAP/SREBP2 and PPARα/γ pathways.

5.1 Anti-inflammatory and immunomodulatory effects

Inflammation accelerates organ injury through multiple mechanisms, while targeted anti-inflammatory intervention can significantly delay the progression of the disease associated with the inflammation. Current evidence demonstrates that AM downregulates pivotal inflammatory mediators—including M1 macrophage-derived cytokines (IL-1β, IL-12, IL-6, MMP-12), chemokines (MCP-1), and adhesion molecules (VCAM-1)—in diabetic nephropathy (DN) models (Ge et al., 2016; Gu et al., 2020). This anti-inflammatory action appears central to AM’s therapeutic mechanism, with additional research revealing its ability to modulate ER stress through iRhom2/tumor necrosis factor-α converting enzyme (TACE)/Spliced X-box binding protein-1 (XBP1S) pathways and regulate autophagy via adenosine monophosphate-activated protein kinase (AMPK)- sirtuin 1 (SIRT1) signaling (Liu et al., 2017; Tu et al., 2020). Parallel mechanistic studies reveal that HKC attenuates inflammatory cell activation and infiltration via p38 mitogen-activated protein kinase (MAPK) pathway inhibition, thereby reducing transforming growth factor beta 1 (TGF-β1) expression in nephropathy models (Chen P. et al., 2012). Current evidence establishes AM and HKC as renal protective agents targeting pathogenic T-lymphocyte subsets including Th22 cells, with single-cell RNA sequencing revealing critical renal receptor networks mediating HKC’s suppression of T-cell activation and infiltration (Wu et al., 2024). Simultaneously, these interventions modulate TGF-β1/Smad family member 3 (Smad3) signaling to reduce immune complex deposition in IgA nephropathy (IgAN) and mesangial proliferative glomerulonephritis (MsPGN) (Pei and Li, 2021; Wu et al., 2024), while enhancing erythrocyte-mediated clearance via redistribution of circulating complexes to erythrocyte surfaces—a mechanism shown to limit renal deposition (Hu et al., 2011). These multimodal actions collectively substantiate HKC’s clinical efficacy in IgAN through integrated immunoregulation (Pei and Li, 2021).

In addition, intestinal inflammation drives IBD progression by mediating tissue damage, fibrosis, and carcinogenesis. In 2,4,6-trinitrobenzenesulfonic acid solution (TNBS)/dextran sodium sulfate (DSS)-induced colitis models, AM ethanol extract attenuates pro-inflammatory cytokines (IL-6, IL-1β, IL-18, IL-17, TNF-α) and reduced myeloperoxidase activity in serum and colonic tissues (Cheng et al., 2015; Xue et al., 2023). Mechanistically, AM suppresses Nod-like receptor protein 3 (NLRP3) inflammasome activation via β-arrestin1 inhibition—evidenced by reducing NLRP3/apoptosis-associated speck-like protein containing caspases recruitment domain (ASC)/caspase-1 expression (Wu et al., 2021). Immune modulation studies revealed AM’s capacity to normalize T helper 17 cell (Th17)/regulatory T cell (Treg) balance through peroxisome proliferator-activated receptor gamma (PPAR-γ)-mediated enhancement of Treg cytokines (IL-10, TGF-β) with concurrent Th17 marker suppression (Qiao et al., 2021). In vitro studies confirmed AM’s inhibition of nuclear factor kappa B (NF-κB) and MAPK signaling in lipopolysaccharide (LPS)-stimulated macrophages (Zhang D. et al., 2019). Immune cell infiltration is critical in initiating and propagating the immune response against pathogens during the progression of UC (Neurath, 2014). This process is tightly regulated by adhesion molecules that mediate interactions between vascular endothelial cells and immune cells (Besendorf et al., 2022). Recent work identified the total flavonoids of AM (TFA) suppression of tumor necrosis factor-alpha (TNF-α)-induced NF-κB activation in colonic endothelial cells, thereby reducing vascular adhesion molecule expression (ICAM-1, VCAM-1, MAdCAM-1) and monocyte recruitment (Xue et al., 2023).

5.2 Anti-fibrotic effect

When tissues are damaged (such as due to infection, toxins, ischemia, mechanical injury, or chronic inflammation), the body activates its repair mechanism. The core of fibrosis lies in the activation and proliferation of fibroblasts. By differentiating into myofibroblasts with strong contractile and synthetic capabilities, they produce and secrete extracellular matrix components, thereby isolating the damaged area and preventing the spread of inflammation (Wang et al., 2025). However, as the injury stimulus persists or the repair process becomes imbalanced, the fibrotic response will proceed excessively, persistently and eventually lead to the aggravation of the disease state.

Renal fibrosis, representing the terminal pathological endpoint in CKD, is driven primarily by myofibroblast activation triggered by inflammatory mediators (TNF-α, IL-1β), metabolic disturbances (high glucose/lipid-induced reactive oxygen species (ROS)), mechanical stress, or hypoxia. These insults activate key signaling pathways (such as TGF-β/Smad3) to induce phenotypic transformation. In DN models, HKC suppresses TGF-β1 expression and reduces α-SMA levels (Gu et al., 2021). Furthermore, in unilateral ureteral obstruction models, HKC targets calcium-permeable TRPC channels, specifically modulating TRPC6/NFAT signaling. This mechanism is critical, as the protective effect of HKC is abolished in TRPC6-knockout mice (Gu et al., 2020). The protective role of HKC in renal disease is primarily mediated through the critical TRPC6/NFAT pathway, as complemented by its suppression of the TGF-β1/α-SMA axis. In addition, mechanistic studies reveal HKC’s capacity to inhibit fibrogenesis through coordinated p38 MAPK/phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) pathway downregulation (Mao et al., 2015), NLRP3 inflammasome suppression with toll-like receptor 4 (TLR4)/NF-κB blockade to prevent epithelial-mesenchymal transition (Han et al., 2019), NOX/ROS/ERK axis modulation (Li et al., 2019), and angiogenic receptor (VEGFR, PDGFR) inhibition coupled with pericyte myofibroblast transdifferentiation suppression (Wang M. et al., 2022). These actions are further complemented by connective tissue growth factor/osteopontin reduction via Smad7/SnoN upregulation and Klotho/TGF-β1/p38 pathway normalization in renal tubular cells (Gu et al., 2021). These studies collectively demonstrate that HKC orchestrates a coordinated suppression of critical pro-fibrotic pathways—including p38 MAPK/PI3K/Akt, TLR4/NF-κB/NLRP3, and NOX/ROS/ERK—thereby counteracting fibrogenesis at multiple levels.

Intestinal fibrosis—a pivotal complication in IBD progression with over 50% incidence in Crohn’s disease—drives intestinal stenosis, obstruction, and surgical intervention through excessive ECM deposition and pathological myofibroblast activation. AM counteracts this remodeling by reducing TNBS-induced weight loss, disease activity index (DAI) scores, and collagen deposition while improving histopathological features (Zhang et al., 2017). Mechanistically, AM suppresses fibrotic markers (col1a2, col3a2, α-SMA) via dual inhibition of TGF-β and IGF-1 signaling (Qiao et al., 2021; Zhang et al., 2024), remodels ECM through altered MMP/TIMP balance (elevated MMP-9/MMP-2 with suppressed TIMP-1), and attenuates TGF-β1-induced epithelial-mesenchymal transition (EMT) by blocking Smad2/3 phosphorylation and MAPK cascades (Yang et al., 2018). In vitro evidence confirms AMPK/mTOR-regulated autophagy mediates AM’s inhibition of IGF-1-driven collagen synthesis in intestinal fibroblasts (Zhang H. et al., 2022), establishing a multi-target therapeutic profile against fibrogenesis.

5.3 Metabolic and anti-oxidant regulation

The ethanol extract showed superior efficacy and reduced hyperglycemia-induced ROS in pancreatic β-cells (Wang S. W. et al., 2024). AM total flavonoids, TFA, enhanced glucose metabolism through dose-dependent promotion of glucose uptake in 3T3-L1 adipocytes and exerted hypoglycemic effects in diabetic murine models. TFA administration elevated superoxide dismutase (SOD) activity while reducing malondialdehyde (MDA) levels in diabetic rats, suggesting β-cell protection against oxidative damage (Zhou and Chen, 2016).

The ethanol extract of AM inhibited TG accumulation in 3T3-L1 adipocytes and lowered serum TC, TG, low-density lipoprotein cholesterol (LDL-C), and ox-LDL levels in hyperlipidemic rats, achieved through downregulation of PPARγ and CCAAT/enhancer-binding protein alpha (C/EBPα) mRNA to inhibit adipogenesis (An et al., 2011; Li J. et al., 2016). At the molecular level, AM ethanol extract orchestrates lipid homeostasis by normalizing adipogenic regulators (PPARα/γ, C/EBPα, SREBP-1), correcting adipokine imbalances (adiponectin/resistin), and alleviating ER stress-induced lipid dysmetabolism. Synergistically, TFA combined with glipizide reduced plasma lipids, blood urea nitrogen (BUN), creatinine, urinary microalbumin, and blood viscosity in DN rats (Li et al., 2018). Metabolic profiling reveals HKC’s systemic modulation of circulating metabolites including methionine sulfoxide, branched-chain amino acids, and cis-7-hexadecenoic acid (Shi et al., 2023). Complementary renal protection involves improved sodium handling via inhibition of renal medullary Na+-K+-ATPase activity, reducing pathological edema and lipid deposition in diabetic kidneys (Cai et al., 2016; Li et al., 2018; Qian et al., 2023).

AM also has a significant antioxidant effect. AM accelerates scald wound healing by modulating MDA/SOD via nuclear factor erythroid 2-related factor 2 (Nrf2) (Song et al., 2024), protects NIH-3T3 fibroblasts from H2O2 damage through the same pathway, and alleviates gastric mucosal injury by boosting glutathione synthesis (Hsuan et al., 2024). Furthermore, AM flower extracts enhance human fibroblast proliferation through cyclin D1 upregulation (Park et al., 2020) and HKC reduces ROS/NO in LPS-activated macrophages and increases lung catalase (CAT)/glutathione peroxidase (GSH-Px) activity in acute lung injury models (Deng et al., 2021). Several studies have revealed that AM exhibits antioxidant activity through scavenging DPPH/ABTS/OH radicals while enhancing antioxidant enzymes (GSH-Px, CAT, SOD, T-AOC) and reducing MDA levels (Qiu et al., 2017; Liu et al., 2021c; Sun et al., 2024). Its total flavonoid fraction TFA activates Nrf2 signaling to upregulate heme oxygenase-1 (HO-1)/NAD(P)H dehydrogenase quinone 1 (NQO1), mitigating D-galactose-induced hepatocyte cytotoxicity (Qiu et al., 2017).

5.4 Regulation of intestinal flora

The intestinal microbiota’s pivotal role in IBD pathogenesis is increasingly recognized, with microbial dysbiosis driving immune activation through commensal flora infiltration into lamina propria. Clinical observations reveal reduced microbial diversity in IBD patients, where therapeutic strategies like probiotics and fecal microbiota transplantation (FMT) demonstrate clinical efficacy by restoring ecological balance (Weingarden and Vaughn, 2017; Tao P. et al., 2024; Zhao H. et al., 2024). In DSS-induced colitis models, AM intervention reverses Firmicutes depletion and Bacteroidetes expansion while enriching beneficial taxa (Akkermansia muciniphila, Lachnospiraceae, Bifidobacterium) and suppressing pathogens (Escherichia coli, Proteobacteria) (Zhang W. et al., 2019; Bu et al., 2021). Cohousing experiments demonstrate AM-treated mice attenuate colitis severity in cohabited counterparts (Gao et al., 2022), with fecal microbiota transplantation confirming microbiota-dependent protection via increased Bacteroides and Ruminiclostridium [sp. cluster 9] in UC recipients (Wu et al., 2021). Notably, AM selectively enhances butyrate-producing Lachnospiraceae to boost short-chain fatty acid (SCFA) production—critical for mucosal integrity and inflammation suppression (Zhang W. et al., 2019) —and directly stimulates A. muciniphila proliferation in vitro (Bu et al., 2021). In addition, AM polysaccharides enhance mucin production via IL-10-dependent pathways, with bacterial transfer studies confirming A. muciniphila as a key mediator of this protective effect (Wang Y. et al., 2024), establishing microbial-metabolic modulation as a viable barrier rehabilitation strategy.

5.5 Organ protection

Cerebral ischemia, characterized by insufficient cerebral blood flow leading to oxygen/glucose deficiency, underlies pathologies like cerebral infarction and vascular dementia with high disability/recurrence rates (Chen et al., 2025). AM administration mitigates cerebral edema, attenuates infarct volume, and improves blood-brain barrier integrity while reducing serum biomarkers (LDH, MDA, and PGE2) of neuronal damage in cerebral ischemia-reperfusion injury model (Guo and Chen, 2002; Gao et al., 2003; Wen and Chen, 2006). AM further enhances hippocampal neuron survival by inhibiting intracellular Ca2+ overload and lactate dehydrogenase (LDH) release during hypoxia/reoxygenation, while its total flavonoids (TFA) suppress N-methyl-D-aspartate (NMDA) receptor-mediated excitotoxicity via non-competitive receptor desensitization—validated by patch-clamp electrophysiology (Cheng et al., 2006; Wen and Chen, 2017). In post-stroke depression (PSD) models, TFA enhances locomotor activity and improves hemorheological parameters by reducing blood viscosity while increasing erythrocyte deformability. Concurrently, it elevates SOD/GSH-Px activities and reduces levels of MDA, adrenocorticotropic hormone (ACTH), and cortisol in both brain tissue and the hypothalamus (Hao et al., 2007; Hao and Zhou, 2009). These effects are achieved by TFA’s suppression of lipid peroxidation and upregulation of brain-derived neurotrophic factor (BDNF)/cAMP response element-binding protein (CREB) neurotrophic pathways (Liu et al., 2009). In neuronal oxidative stress models, AM ethanol extract directly protects neuronal PC12 cells against oxidative stress through antioxidant enzyme induction, glutathione (GSH) synthesis promotion, DNA repair enhancement, and ROS reduction (Wang S. W. et al., 2022). Critically, AM modulates the gut-brain axis to alleviate depression-associated intestinal barrier damage and microbial dysbiosis, concurrently ameliorated depressive behaviors and DSS-induced colitis (Wang et al., 2021).

AM, traditionally used in Jiangsu and Anhui provinces for jaundice and hepatitis management, exerts hepatoprotection primarily through its total flavonoid component (Liu et al., 2010). In CCl4-induced liver injury models, TFA significantly reduces serum markers (ALT, AST, ALP, γ-GT) and hepatic MDA while elevating GSH content, concurrently enhancing antioxidant enzyme activities (SOD, GSH-Px, CAT, GST) and suppressing inflammatory mediators (TNF-α, IL-1β, NO) (Hu et al., 2011; Ai et al., 2013). TFA’s dose-dependent cytoprotection in CCl4-exposed hepatocytes, evidenced by improved cell viability and reduced ALT/AST/ALP leakage (Ai et al., 2013). In cholestatic models, TFA upregulates bile transporters (BSEP, MRP2, NTCP) at protein/mRNA levels (Yan et al., 2015). In D-galactose-induced aging models, TFA activates the Nrf2 pathway to boost antioxidant capacity (CAT, T-SOD, GSH-Px, T-AOC) and inhibit peroxidation (Qiu et al., 2017). In vitro analyses confirm AM’s ethyl acetate fraction protects HepG2 cells from H2O2-induced damage through ROS scavenging, membrane stabilization, and apoptosis modulation via Nrf2/HO-1/NQO1 pathway activation and caspase-3/9/Bax regulation (Liu et al., 2021c).

5.6 Antiviral, antibacterial, and ulcer repair

AM and its total flavonoid component exhibit broad-spectrum antimicrobial activity against viral and bacterial pathogens. TFA potently inhibits herpes simplex virus types 1/2 (HSV-1 IC50 = 1.01 mg/L; HSV-2 IC50 = 1.21 mg/L) with high therapeutic indices (>10), indicating selective antiviral action (Jiang et al., 2006). Gao et al. found that AM ethanol extract reduces influenza A viral loads and suppresses pulmonary IL-1β/IL-6/TNF-α via MAPK pathway modulation in murine models (Gao et al., 2022). Against bacterial pathogens, AM demonstrates efficacy against Gram-positive/negative species, particularly Neisseria gonorrhoeae, with TFA exhibiting bactericidal activity against Staphylococcus epidermidis and Staphylococcus aureus (MIC = 3.125 g/L) and fungistatic effects on Candida albicans (MIC = 1.562–3.125 g/L) (Zhang et al., 2006). These properties translate to therapeutic efficacy in mucosal infections: TFA accelerates healing of C. albicans- or S. epidermidis-induced oral ulcers in guinea pigs, and AM flower extract reduces inflammation in S. aureus-infected rabbit oral mucosa (Li et al., 2006; Zhang et al., 2006).

5.7 Antipyretic and analgesic effects

AM and its total flavonoid component exhibit antipyretic and analgesic properties through distinct biological pathways. In rabbit fever models induced by turpentine oil or E. coli, TFA reduced body temperature within 150 minutes—albeit with slower onset than aspirin due to delayed systemic absorption and hepatic metabolism (Fan et al., 2003b). For analgesia, TFA (5–20 mg/kg) significantly inhibited acetic acid-induced writhing responses (42.81%–57.53% reduction) and attenuated potassium chloride-evoked nociception without inducing addictive behaviors even at 280 mg/kg (Fan et al., 2003a). TFA significantly reduced pain responses in rabbits following potassium chloride injections (Fan et al., 2003a). Petroleum ether and methanol extracts of AM also exhibited a dose-dependent inhibition on thermopain (Jain et al., 2011), and AM extracts alleviate burn-induced inflammatory exudation and elevate pain thresholds in scalded models (Song et al., 2024).

6 Traditional Chinese medicine formulas containing AM

Clinical trial of Chinese herbal formula containing AM.

6.1 Jiahua tablets

Jiahua Tablets are semi-extracted TCM tablets made from the raw powder and extracts of AM flowers, containing 10% starch slurry and an appropriate amount of ethanol. These tablets have been clinically used for over a decade and have been demonstrated to display significant therapeutic efficacy (Lin et al., 2020a; Zha et al., 2020). Both HKC and Jiahua Tablets are derived from the single medicinal ingredient of AM flowers. They share properties that clear heat, promote diuresis, support kidney function, and eliminate toxins, primarily addressing acute and chronic nephritis (Zhang and Zhou, 2012). According to the Chinese Pharmacopoeia, the recommended dosage of AM flowers is 10–30 g/day, with both HKC and Jiahua Tablets containing a daily dosage of 30 g of AM flowers.

In addition to conventional early DN treatments, Jiahua Tablets can reduce serum inflammatory factors such as C-reactive protein (CRP) and TNF-α. It also lowers levels of Cystatin C (Cys-C) and urinary albumin-to-creatinine ratio (UACR), thereby improving kidney function (Cha et al., 2020). In patients undergoing coronary intervention, those treated with Jiahua Tablets exhibited significantly lower levels of serum creatinine (SCr), BUN, Cys-C, IL-6, IL-8, high-sensitivity C-reactive protein (hs-CRP), urinary N-acetyl-β-D-glucosaminidase (NAG), and urinary β-galactosidase (GAL) 72 h post-operation compared to the control group. Additionally, the estimated glomerular filtration rate (eGFR) was significantly higher in the treatment group than in the control group, indicating that Jiahua Tablets can effectively prevent contrast-induced nephropathy. The underlying mechanism likely involves inhibiting inflammatory responses and protecting renal tubules, thereby repairing kidney damage and preserving renal function (Wu et al., 2020).

6.2 Chuangling liquid

Chuangling Liquid was developed by the Jiangsu Provincial Hospital of TCM in the 1980s. Its formulation including A. manihot (Huang Shu Kui), Rheum palmatum (Da Huang), Carthamus tinctorius (Hong Hua), and Terminalia chebula (He Zi) (Yang, 1997; Xu, 2010; Huang and Chen, 2012; Miao, 2013; Yin et al., 2013; Cao et al., 2014; Sheng, 2014; Teng and Ji, 2016; Wang et al., 2016; Li, 2017; Liu, 2019; Wang et al., 2020; Xue et al., 2020; Ye et al., 2021). The primary active components of Chuangling Liquid include gallic acid, hyperoside, isoquercitrin, myricetin, quercetin, rhein, emodin, chrysophanol, and physcion (Shu et al., 2016). This preparation promotes blood circulation and removes blood stasis, effectively treating various types of infectious ulcers with significant inflammation (Chen et al., 2017).

Chuangling Liquid has demonstrated a range of therapeutic properties in various experimental and clinical settings. Zhang et al. showed that it can counteract acute exudative inflammation induced by croton oil in mice and inhibit granulation tissue proliferation in cotton pellet granuloma models (Zhang et al., 1997). In rabbit ulcer models, Chuangling Liquid promotes early wound healing processes such as epithelial tissue proliferation, granulation formation, and accessory regeneration, while inhibiting collagen fiber scar formation, leading to faster healing with less scarring (Zhang et al., 1997). Additionally, it exhibits strong antibacterial activity against S. aureus, methicillin-resistant S. aureus (MRSA), and Proteus species, being particularly effective at eliminating MRSA from infected wounds and promoting recovery (Liu et al., 2018). Moreover, Chuangling Liquid also inhibits thrombosis and platelet aggregation, thereby improving blood circulation and alleviating blood stasis (Chen et al., 2017). Clinically, it has been proven effective in treating postoperative infected wounds, chronic ulcers, diabetic foot ulcers, venous ulcers of the lower limbs, and anal fistulas (Hu, 2016; Li, 2016; Xu, 2017). Furthermore, modifying the formulation process and incorporating collagen into Chuangling Liquid enhances its anti-inflammatory effects, wound healing, angiogenesis, and overall recovery (Zhao and Zhu, 2013). Recent studies have also found that Chuangling Liquid promotes the proliferation of immortalized melanocytes in mice and activates tyrosinase activity, enhancing melanin synthesis. This suggests potential applications in treating pigmentary disorders such as vitiligo (Zhou et al., 2019).

6.3 Huangkui Lianchang decoction

Huangkui Lianchang Decoction (HLD) is a traditional Chinese medicinal formulation used to treat UC. It consists of six key ingredients: the primary herb is A. manihot (Huang Shu Kui), combined with Euphorbia humifusa Willd (Di Jin Cao), Pteris multifida Poir (Feng Wei Cao), Lithospermum erythrorhizon Siebold & Zucc (Zi Cao), Rubia cordifolia L. (Qian Cao), and Rhus chinensis Mill (Wu Bei Zi) (He et al., 2019; Yang et al., 2023). HLD is rich in flavonoids, including rutin, isoquercitrin, gossypetin, and quercetin (Cheng et al., 2022). The proposed functions of HLD are to clear heat and dampness, activate blood circulation, protect the intestines, and detoxify the body. These properties make it particularly beneficial for managing the symptoms associated with UC.

HLD has demonstrated significant therapeutic effects on DSS-induced UC in mouse models. Studies indicate that HLD exerts anti-inflammatory effects by modulating key signaling pathways, including NF-κB, IL-6/signal transducer and activator of transcription 3 (STAT3), and the IL-23/IL-17 inflammatory axis (He et al., 2019; He et al., 2020; Cheng et al., 2022). In vitro experiments with drug serum containing HLD (HLD-DS) showed that it reduces inflammatory cytokine levels while increasing IL-10 levels in NCM460 cells. HLD-DS also decreased the expression of p-NF-κB p65, LC3II/I, and Beclin 1, suggesting that HLD alleviates colitis by inhibiting the NF-κB pathway and autophagy (Cheng et al., 2022). Clinically, HLD is used for treating mild to moderate E1 and E2 type UC via enema alone. In contrast, severe or E3-type UC is treated with HLD enemas and oral medications (He et al., 2019). Clinical studies have shown that modified HLD, when used alongside corticosteroids, can effectively improve gut microbiota and exhibit significant anti-inflammatory effects, aiding in managing IBD (He et al., 2023). Additionally, the retention enema method of HLD has been found to inhibit the intestinal mucosal inflammatory response in UC patients and reduce mucosal damage (Yang et al., 2023).

6.4 Huangkui Siwu Formula

Huangkui Siwu Formula (HKSWF) is a traditional Chinese medicinal formulation comprised of four key herbs: A. manihot (Huang Shu Kui), Astragalus mongholicus (Huang Qi), Polygonum cuspidatum (Hu Zhang), and Curcuma longa L (Jiang Huang) (Lu T. et al., 2020). The formula contains eleven identified components, including polydatin, hyperoside, isoquercitrin, hibifolin, myricetin, resveratrol, quercetin, didemethoxycurcumin, demethoxycurcumin, curcumin, and emodin (Lu T. et al., 2020). The herbal combination in HKSWF clears heat, promotes blood circulation, facilitates urination, and reduces swelling, effectively addressing the symptoms of CKD.

Research on HKSWF has shown promising therapeutic effects in kidney health, particularly in an anti-Thy-1 nephritis model. One study indicates that HKSWF can alleviate glomerular injury by attenuating pyruvate dehydrogenase activity, contributing to its protective effects on renal function (Lu T. et al., 2020). Further investigations by Lu et al. revealed that HKSWF does not alter the expression of organic anion transporters in the kidneys or the transport of p-cresyl sulfate (PCS) from blood to kidneys. Instead, it regulates the synthesis pathway of PCS within host cells, inhibiting its endogenous production. This action helps reduce the accumulation of uremic toxins and slows the progression of CKD (Lu et al., 2021). Moreover, HKSWF modulates uremic toxin metabolism pathways within the gut microbiota, inhibiting the formation of uremic toxin precursors at various stages. This modulation alleviates the symptoms associated with uremic toxin accumulation and further delays CKD progression, highlighting the multifaceted benefits of HKSWF for managing kidney health (Lu J. et al., 2020).

6.5 Yu Kui Qing

Yu Kui Qing (YKQ) is composed of A. manihot (Huang Shu Kui), Astragalus membranaceus (Huang Qi), and Polygonum multiflorum Thunb. (Zhi Shou Wu) (30:1.5:1) (Chen and Yu, 2008; Chen and Yu, 2009). YKQ clears heat, detoxifies, promotes diuresis, tonifies Qi, strengthens the spleen, activates blood circulation, and nourishes Yin and kidneys. Modern pharmacological studies have demonstrated that YKQ can reduce the expression and chemotactic effects of chemokines in human renal mesangial cells (HRMC) induced by advanced glycation end-products bound to bovine serum albumin (AGE-BSA). Additionally, YKQ intervenes in the expression of connective tissue growth factor (CTGF) mRNA and protein in HRMC, which may contribute to reducing renal inflammation associated with DN (Yang et al., 2010; Sun et al., 2014). Clinical studies have shown that YKQ effectively treats microalbuminuria in patients with type 2 DN, reduces urinary microalbumin levels, and improves symptoms (such as fatigue and lower back pain) in early-stage disease. These findings underscore the potential of YKQ as a valuable therapeutic option for managing diabetes-related complications (Chen and Yu, 2009).

6.6 Qikui Granules

Qikui Granules is composed with A. membranaceus (Huang Qi), A. manihot (Huang Shu Kui), and processed P. multiflorum (Zhi Shou Wu) (Wang L. et al., 2023). Specifically, they help to benefit Qi, nourish Yin, and clear heat. Clinically, Qikui Granules have been utilized to treat early to mid-stage DN (Yang et al., 2016).

The study by Lou et al. shows that Qikui Granules provide renal protection in DN by lowering blood glucose, reducing inflammatory markers like IL-6, monocyte chemoattractant protein-1 (MCP-1), and TGF-β1, and inhibiting the p38 MAPK signaling pathway (Yang et al., 2016; Shao et al., 2017). In addition to renal benefits, Qikui Granules were observed to improve bone density, likely linked to improved blood glucose regulation (Lou et al., 2022). In vitro experiments revealed that these granules enhance the proliferation of mesenchymal stem cells (MSCs) and promote their osteogenic differentiation while simultaneously reducing their potential for adipogenic differentiation (Lou et al., 2022). Clinically, Qikui Granules have been shown to reduce microalbuminuria in patients with early DN. It slows disease progression and alleviates symptoms such as fatigue, weakness, lower back and knee soreness, and facial and limb edema (Yan et al., 2018). Observations indicate a marked reduction in urine protein levels, UACR, urinary albumin excretion rate (UAER), and urinary MCP-1/creatinine (uMCP-1/Cr) levels in patients with early DN (Yan et al., 2018). The underlying mechanisms of action for Qikui Granules may involve inhibiting CTGF expression and soluble intercellular adhesion molecule-1 (sICAM-1) in urine and serum (Xie et al., 2017b; Zhang et al., 2021). Overall, the findings suggest that Qikui Granules could be a valuable therapeutic approach for managing complications associated with diabetes, particularly DN, by addressing metabolic and inflammatory pathways.

6.7 Huangshu Kuihua paste

The Huangshu Kuihua paste, which combines 0.3–10 parts of A. manihot (Huang Shu Kui) with 0.1–10 parts of propolis extract and 0.1-5 parts of borneol, is an innovative formulation widely used at the First Affiliated Hospital of Anhui Medical University (Han and Situ, 1997; Chen et al., 2017). Its strong analgesic properties make it particularly effective for managing pain associated with oral ulcers. Notably, the formulation is characterized by minimal tissue irritation and does not cause local numbness or discomfort, which enhances patient comfort during treatment. Moreover, the paste exhibits excellent adhesion to mucous membranes, facilitating prolonged contact and promoting the healing process of oral ulcers without any toxic side effects. In clinical trials involving 82 patients with oral ulcers, the formulation achieved an impressive cure rate of 97.5%, underscoring its efficacy and safety in treating this condition (Han et al., 1997). These findings make Huangshu Kuihua paste a valuable option in managing oral ulcer pain and healing.

6.8 Er Huang ointment

Er Huang Ointment, formulated with A. manihot (Huang Shu Kui), Scutellaria baicalensis (Huang qin), Phellodendron amurense (Huang bai), Gardenia jasminoides (Zhi zi), and Ampelopsis japonica (Bai lian) (5:5:5:3:3), has garnered attention for its therapeutic effects on burns and wounds (Yang, 2016). Clinical studies have affirmed that the overall efficacy of Er Huang Ointment in treating burns and scalds and reducing wound healing time is comparable to that of Moist Burn Ointment (Yang et al., 2016; Guo and Wang, 2017). Furthermore, Er Huang Ointment has notable antibacterial activity against common pathogens such as S. aureus, Pseudomonas aeruginosa, and E. coli, suggesting its potential in preventing infections associated with burns and wounds (Li, 1993). These findings position Er Huang Ointment as a promising clinical practice option for managing burns and enhancing wound healing.

7 Research challenges and future perspectives

The traditional Chinese medicinal herb AM features pale yellow flowers with a delicate fragrance and holds significant ornamental, medicinal, and edible value. Modernizing AM faces two core challenges: degree of development and utilization, and gaps in translation from laboratory to clinic. Jiangsu Suzhong Pharmaceutical Co., Ltd. in Taizhou (Jiangsu, China) has successfully developed and commercially produced HKC—a Category III new TCM—after years of research. These capsules are widely used clinically to treat conditions such as nephritis and rheumatoid arthritis, serving as an adjunctive therapy for glomerulonephritis and demonstrating considerable value in preventing gadolinium-based contrast agent-induced nephrogenic systemic fibrosis. Utilizing AM flowers as the primary raw material, the proven efficacy and substantial market potential of these capsules have driven high demand, consequently stimulating the flourishing cultivation industry across Taizhou, Jiangsu, surrounding regions, and nationwide. However, other AM parts—including leaves, roots, stems, and seeds—are typically discarded, resulting in resource wastage and environmental pollution. Literatures indicate that the entire AM plant possesses medicinal properties, suggesting that non-capsule components also hold therapeutic value. To enable more scientific, comprehensive, and rational utilization of this medicinal resource, intensified research on its other bioactive parts is essential. This will maximize economic and social benefits while accelerating the development of the AM industry.

Transitioning to evidence-based medicine is hampered by significant clinical evidence gaps, including small randomized controlled trials with fewer than 300 cases, short follow-up periods of 6 months or less, reliance on surrogate endpoints like proteinuria instead of hard endpoints such as end-stage renal disease incidence, and insufficient long-term safety data on aspects like reproductive toxicity. Currently, only HKC has gained broad clinical acceptance, primarily for treating nephropathy. This is due to its robust clinical data, characterized by rigorous record-keeping, standardized patient grouping, sufficient sample sizes, and sustained post-treatment follow-up. Other AM-containing TCM formulations suffer from significant clinical evidence gaps: their studies often involve small, non-systematic patient cohorts and lack post-administration observation. This evidence deficit severely limits the broader clinical adoption and justification for using AM. Therefore, building upon the systematically compiled data on AM-containing TCM formulations presented in this study, it is recommended to prioritize 1-2 promising prescriptions for development. Conducting standardized clinical research on these selected formulations is crucial. This focused approach will enhance the understanding of AM’s therapeutic potential and ultimately expand its clinical applications.

8 Conclusion

Based on the current body of evidence derived from both basic research and clinical practice, AM has demonstrated significant therapeutic potential. Its pharmacological activities, including the improvement of liver and kidney functions, regulation of material metabolism, and anti-fibrotic effects, have been scientifically validated, providing a rationale for its application in conditions such as CKD and IBD (Miao et al., 2024a; Wang Y. et al., 2024; Zhao H. et al., 2024). However, the predominant clinical application remains limited to the single-component preparation HKC (Geng et al., 2023), underscoring the need to broaden the development and utilization of AM-derived formulations.

Notwithstanding this promise, current research faces notable limitations that must be addressed in future studies. These include a narrow focus on the flowers and total flavonoids, neglecting other plant parts and individual bioactive compounds; the use of animal models that may not accurately replicate human diseases; insufficient mechanistic insights at cellular and molecular levels; and a lack of integrated pharmacokinetic-pharmacodynamic (PK-PD) studies to represent the whole herb’s in vivo behavior. Consequently, future efforts should prioritize expanding phytochemical investigations, pinpointing specific bioactive compounds and their mechanisms, establishing integrated PK-PD models, and developing improved formulations through rigorous clinical trials. Overcoming these challenges via a multidisciplinary approach is essential to fully realize the clinical potential of AM.
