Medicinal & Culinary Use
Grown as a leaf vegetable, particularly in Vietnam, where it is called giấp cá or diếp cá and is used as a fresh herbal garnish. The leaf has an unusual taste that is often described as fishy (earning it the nickname "fish mint"), so it is not enjoyed as universally as basil, mint, or other more commonly used herbs.
Houttuynia is also used in herbal medicine. The beverage dokudami cha (Japanese: ドクダミ茶; literally "Houttuynia cordata tea") is an infusion made from Houttuynia cordata leaves, Oolong tea leaves, and Job's Tears.
In the southwestern Chinese provinces of Yunnan, Guizhou, and Sichuan, roots are used as a root vegetable. English names include heartleaf and lizardtail.
