Helicid, a compound derived from Hovenia dulcis, is widely used in traditional Chinese medicine for its hepatoprotective properties, particularly in mitigating alcohol-induced liver damage, hangovers, and supporting liver function. It also exhibits sedative and anti-anxiety effects, helping with insomnia, nervous disorders, and stress relief. Commonly found in herbal formulations for its calming and neuroprotective qualities, it can cross the blood-brain barrier. In research settings, it is investigated for mechanisms of sleep regulation, anxiety reduction, antioxidant activity, and potential therapeutic applications in neurology and addiction treatment.
