Ampelopsin
Chemical compound
From Wikipedia, the free encyclopedia
Ampelopsin, also known as dihydromyricetin and DHM, when used as an herbal medicine, 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
Research suggests that ampelopsin protects against doxorubicin-induced cardiotoxicity by inhibiting NLRP3 inflammasome activation via stimulation of the SIRT1 pathway.[4] In a study of 60 patients with non-alcoholic fatty liver disease, ampelopsin improved glucose and lipid metabolism and yielded potentially beneficial anti-inflammatory effects.[5] A study of rats demonstrated pharmacological properties of ampelopsin which suggest it would be a therapeutic candidate to treat alcohol use disorders.[6]
Additional research is required before claims of human efficacy and application, necessary dosage, and solutions to poor bioavailability, are met with scientific validation.[7]
Purported benefits
Ampelopsin has been claimed to possess various health, wellness, and cosmetic benefits, including:
- Anti-alcohol intoxication: ampelopsin is widely used in hangover remedies due to its claimed ability to accelerate alcohol breakdown in the liver and mitigate alcohol-induced damage.[3] However, a pharmacokinetic study found no effect of DHM on alcohol metabolism.[8]
- Cosmetic applications: ampelopsin is used in skincare products for its purported ability to protect skin from UV-induced damage and aging.[9]
