History of hovenia use**
K’ung Fu Tzu (Latinized as Confucious) lived from 551–470 BCE, and considered the author Book of Songs.
The book includes 300 traditional songs of the Zhou Dynasty (1066–221 BCE) with hundreds of references to food,
providing an agricultural picture of the  age. Book of Songs mentions 44 food plants. Raisin tree (Hovenia dulcis) is
included in the 44 food list as fruits

What is Hovenia dulcis? * [6]
-
Plant Extract Attenuates the Effects of Alcohol (The Journal of Neuroscience, January 4, 2012)

Fruit of the Japanese raisin tree, Hovenia dulcis, has long been used in East Asia to reduce alcohol intoxication and
treat alcohol poisoning. It does this partly by speeding alcohol catabolism: extracts of the fruit increase the activity of alcohol
dehydrogenase and acetaldehyde dehydrogenase.  Additional effects of H. dulcis may make it useful in treating alcohol withdrawal.
Chronic alcohol use reduces GABAergic inhibition, thus producing tolerance and causing withdrawal symptoms
such as anxiety and increased seizure susceptibility
.

Hovenia dulcis is listed among the premier anti-hangover herbal medicines in China’s first pharmacopoeia, the Tang
Materia Medica (Su, 659).
Hovenia extracts ameliorate alcohol induced liver injuries (Du et al., 2010) and relieves hangover,partly
by promoting EtOH elimination via enhancement of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH)
activity (Kim et al., 2000; Chen et al., 2006).








Dihydromyricetin As a Novel Anti-Alcohol Intoxication Medication:*[6]
Here we demonstrate that dihydromyricetin [(2R,3R)-3,5,7-trihydroxy-2-(3,4,5-trihydroxyphenyl)-2,3-dihydrochromen-4- one (DHM)],
a flavonoid component from Hovenia, is highly effective in counteracting acute EtOH intoxication, EtOH exposure/ withdrawal-
induced GABAAR plasticity and AWS symptoms, as well as reducing excessive EtOH consumption. We provide strong evidence that
DHM is a candidate for development as a novel AUD therapy.
