Ultrasonic water (UW) is a new type of functional drinking water. In the study, the SD rats with constipation were established to explore the purgative effect and mechanisms of UW. Safety of UW was evaluated by acute oral toxicity test, subacute oral toxicity test, micronucleus test of bone marrow cells, and Ames test. The results indicated that UW significantly improved constipation symptoms of the test SD rats, with a significant increase in body weight (16.03 ± 5.32%) compared to the model group (8.67 ± 4.02%, P < 0.05). Compared to the model group, serum levels of excitatory gastrointestinal hormones were significantly elevated 4.20% (motilin), 10.87% (substance P), 36.69% (vasoactive intestinal peptide) and 12.89% (acetylcholinesterase) (P < 0.05), while somatostatin, was markedly reduced 22.40% (P < 0.05), respectively. Acute oral LD50 values of UW were higher than 20000 mg/kg, indicating practical non-toxicity. In the subacute toxicity test, compared to those in the control group, performances, blood routine indexes and serum biochemical indexes of the rats in the UW group showed no statistical difference (P > 0.05), and all the organs and tissues of the rats in both groups maintained normal morphology. Micronucleus effect of UW was not found when the dosage of UW was up to 20000 mg/kg. UW also showed no mutagenic activity on standard test strains. In summary, UW exhibited favorable purgative effect and safety.
