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]
Research[edit]
Research suggests that DHM protects against DOX-induced cardiotoxicity by inhibiting NLRP3 inflammasome activation via stimulation of the SIRT1 pathway.[4]
In a trial of 60 patients with "nonalcoholic fatty liver disease," dihydromyricetin improved glucose and lipid metabolism and yielded potentially beneficial anti-inflammatory effects.[5]
A study of rats demonstrated pharmacological properties of DHM which suggest it would be a therapeutic candidate to treat alcohol use disorders.[6]
Dihydromyricetin shows poor bioavailability which limits its potential medicinal applications.[7]
Additional research is required before claims of human efficacy and application, necessary dosage, and solutions to poor bioavailability, are met with scientific validation.
