About this Research Topic
Anxiety is an unpleasant state of tension, apprehension, or uneasiness, a fear that seems to arise from a sometimes unknown source. Disorders involving anxiety are the most common mental disturbances. Episodes of mild anxiety are common life experiences and do not warrant treatment. However, the symptoms of severe, chronic, debilitating anxiety may be treated with anti-anxiety drugs. Because many of the anti-anxiety drugs also cause some sedation, the same drugs often function clinically as both anxiolytic and hypnotic agents.
Depression is serious medical condition in which a person feels in a state of low mood and aversion to activity that can affect a person's thoughts, behavior, feelings and sense of well-being. People with depressed mood can feel sad, anxious, empty, hopeless, helpless, irritable, ashamed or restless. Although a number of synthetic drugs are being used as standard treatment for anxiety depression, they have adverse effects that can compromise the therapeutic treatments and patient's compliance. Unlike, synthetic medications, natural products are widely used across the globe due to their wide applicability and therapeutic efficacy associated with least side effects, which in turn has initiated the scientific research regarding the antidepressant activity.
Starting from these premises, the purpose of this special issue is to stimulate researchers around the world, working on natural products, to submit to this special issue review, research article or clinical trials regarding the use of natural products and/or natural-derived compounds as an emerging therapeutic alternative for the treatment of anxiety and depression.
