Clinical verdict
He Shou Wu is one of the world's most hepatotoxic supplements — HUNDREDS of documented liver injury cases across Asia and the West. The 'reverses gray hair' legend drives consumer demand despite clear danger. Raw (unprocessed) root is more toxic than traditionally processed (Zhi He Shou Wu). Chinese CFDA, Korean MFDS, and multiple international regulators have issued specific hepatotoxicity warnings. Any patient presenting with jaundice should be asked about He Shou Wu use [1].
