SAURURACEAE(Lizard's Tail family)
• Medicinal / Folk-medicinal aspects: Extracts and other preparations from plants in this family are used externally, principally in North America and the Far East, as astringents and antimicrobials / antifungals to treat haemorrhoids, wounds, and skin infections. • This small family of bog, swamp, and sub-aquatic plants comprises six species in four genera found in eastern Asia and North America, namely Anemopsis Hook. & Arn., Gymnotheca Decne., Houttuynia Thunb., and Saururus L. (Mabberley 2017). Members of this family were formerly classified in the Piperaceae. Some are cultivated as ornamentals around ponds and in aquaria (Wright & Dewar 1913, Hunt 1968/70).

According to Stuart (1911) in a text on Chinese materia medica, the juice of the fresh leaves is prescribed in poisoned sores, infectious skin diseases, piles, prolapsus ani, and other such conditions. The prepared herbal product is known as yu xing cao (鱼腥草), or as Herba Houttuyniae. A 63-year-old female developed violet-reddish butterfly shape macules on both cheeks and erythematous macules on the forehead, V-neck, chin, nape, forearms, and hands after having taken a decoction prepared from the dried leaves for about twenty days. She gave a weakiy positive patch test reaction to an aqueous extract of the dried leaves. A more strongly positive reaction occurred in photopatch testing with UVB irradiation (Saito & Saito 1995). Houttuynia Cordata Extract / Flower/Leaf/Stem Water / Water / & Powder [INCI; CAS RN 164288-50-0; of uncertain composition (see Schmidt 2017)]a, and also Houttuynia Cordata Flower/Leaf Extract & Houttuynia Cordata Leaf/Stem Extract, INCI names with no assigned CAS RN, are recognised cosmetic product ingredients variously purported to have skin conditioning, antioxidant, emollient, humectant, skin protecting, antimicrobial, masking, and fragrancing properties (Standing Committee on Cosmetic Products 2019, CosIng 2023/4). The genus Houttuynia Thunb. is monotypic, its natural range extending from Japan through China to the mountains of Nepal and to Java (Mabberley 2017).
