Ampelopsin, also known as dihydromyricetin and DHM, when purported as an effective ingredient in supplements and other tonics, is a flavanonol, a type of flavonoid. It is extracted from the Japanese raisin tree and found in Ampelopsis species japonica, megalophylla, and grossedentata; Cercidiphyllum japonicum; Hovenia dulcis; Rhododendron cinnabarinum; some Pinus species; and some Cedrus species,[1] as well as in Salix sachalinensis.[2]

Hovenia dulcis has been used in traditional Japanese, Chinese, and Korean medicines to treat fever, parasitic infection, as a laxative, and a treatment of liver diseases, and as a hangover treatment.[3] Methods have been developed to extract ampelopsin on a larger scale, and laboratory research has been conducted with the compound to see if it might be useful as a drug in any of the conditions for which the parent plant has been traditionally used.[3]
