Brucea Fruit Whole (Brucea javanica) is the dried fruit of a small shrub native to Southeast Asia and widely used in traditional Chinese medicine (TCM) for its strongly bitter, clearing, and detoxifying qualities. Known in TCM as Ya Dan Zi, the fruit is regarded as a cold, intensely bitter herb that targets heat, dampness, and parasites, making it a powerful though specialized remedy. In traditional practice, Brucea Fruit is employed to clear toxic heat, reduce malarial symptoms, and address dysenteric disorders. It has been prescribed for chronic or recurrent diarrhea, malaria, and intestinal parasites, as well as in topical applications for warts, corns, and certain skin growths. Because of its potency, it is often used in small amounts and combined with other herbs to moderate its effects. Modern research has highlighted compounds in Brucea javanica such as quassinoids, fatty acids, and alkaloids, which are associated with antiparasitic, antimalarial, antitumor, and antimicrobial activity. Extracts of the fruit have been studied for potential use in cancer therapy, liver protection, and immune modulation, though its traditional use remains more common. Each batch of Brucea Fruit Whole (Brucea javanica) is carefully harvested and dried to preserve its bitterness, potency, and medicinal value. Typically decocted or powdered for use in classical formulas, it produces a distinctively bitter infusion reflecting its detoxifying and parasite-clearing nature. Note: Brucea Fruit is a very strong herb and should be used only under the guidance of a qualified practitioner. It is not intended for culinary use and is contraindicated during pregnancy and in weak or deficient constitutions.
