Polygala chinensis

Various species of Corydalis (fumewort, Fumariaceae) and Stephania (Jin bu huan) contain tetrahydropalmatine (1), which is the active constituent in Chinese Jin Bu Huan Anodyne tablets, sold on the Western market. The package insert suggested that Polygala chinensis is the source plant, but in reality this alkaloid comes from a species of Stephania. Both 1-tetrahydropalmatine and its racemic dl-form are used in Chinese medicine as analgesic and hypnotic agents.
