Anxiolytic Activity of Several Herbs

Anxiety disorders are among the most prevalent psychiatric conditions globally, often managed with pharmacological agents such as benzodiazepines and selective serotonin reuptake inhibitors (SSRIs). However, these conventional therapies are frequently associated with side effects, dependency, and tolerance, prompting growing interest in safer, plant-based alternatives. Herbal medicines have been used for centuries in various traditional systems and are now being scientifically explored for their anxiolytic potential. This review aims to highlight the anti-anxiety activity of selected herbal drugs, including Withania somnifera (Ashwagandha), Bacopa monnieri (Brahmi), Nardostachys jatamansi (Jatamansi), Valeriana officinalis (Valerian), Matricaria chamomilla (Chamomile), and Passiflora incarnata (Passionflower), among others. The anxiolytic effects of these herbs are attributed to their modulation of key neurotransmitter systems, particularly gamma-aminobutyric acid (GABA), serotonin, and dopamine pathways, along with their antioxidant and neuroprotective properties. Preclinical models such as the elevated plus maze and light/dark box tests, as well as clinical trials, support the efficacy of these herbal agents. While evidence is promising, issues such as standardization, herb-drug interactions, and regulatory oversight remain significant challenges. This review underscores the need for further well-designed clinical studies to validate the safety, efficacy, and mechanisms of herbal drugs in the treatment of anxiety disorders.
