DHM: The Japanese Raisin Tree Compound
Dihydromyricetin (DHM), also known as ampelopsin, is a flavonoid compound found in the Japanese Raisin Tree (Hovenia dulcis). The fruit and bark of this tree have been used in traditional East Asian medicine for over a thousand years — specifically for reducing the effects of alcohol.
Modern supplement science has caught up with traditional knowledge. DHM is now the most studied and most cited ingredient in hangover prevention supplements, included in Revive Capsules at 300mg per dose.
What Type of Compound Is DHM?
DHM belongs to the flavonoid family — a large class of plant-derived compounds found in fruits, vegetables and herbs. Flavonoids are known for their antioxidant properties and have been extensively studied for a range of health applications. DHM is specifically a dihydroflavonol, a subclass with particular characteristics relevant to alcohol metabolism support.
How DHM Is Used in Supplements
In supplement form, DHM is extracted and standardised from Hovenia dulcis. Quality varies significantly between manufacturers — the purity and standardisation of the extract determines how effective the supplement is. Revive uses a standardised DHM extract at a consistent 300mg per dose.
What Research Exists on DHM?
Preclinical research (primarily animal studies) has demonstrated DHM's effects on alcohol metabolism and GABA receptor modulation. Human trials are more limited but growing. The traditional use record — over a thousand years in East Asian medicine specifically for alcohol-related effects — provides a significant real-world evidence base that precedes modern clinical research.
