What is DHM?

DHM (Dihydromyricetin) is an organic, flavonoid compound that can be naturally extracted from two main sources – the Hovenia Dulcis tree and the Ampelopsis Grossedentata plant. It can also be found in tea. (More on those sources later.)

Dihydromyricetin is a hepatoprotective flavonoid. Hepatoprotective chemicals prevent damage to the liver. So not only is DHM effective in counteracting alcohol intoxication, but it can actually protect your liver from the negative effects of alcohol.

The DHM molecule is also known as Ampelopsin. It is a traditional Asian herbal medicine and dietary supplement. DHM is listed as a premier anti-hangover medicine in China’s first pharmacopeia, Tang Materia Medica

This miracle molecule can minimize the effects of alcohol consumption. For others, it produces zero side effects of being drunk. It can also be used to prevent intoxication or even reduce the desire to drink.

The substance DHM is soluble in hot water. It becomes irreversibly oxidized at temperatures over 100 degrees Celsius.

Dihydromyricetin is typically consumed as a powder or mixed as a soluble solution in lab tests.

Where is DHM from?

The first major source of the herb DHM is from the Hovenia Dulcis tree. This tree is known by many names including the Japanese raisin tree, Cedrus Deodara tree, and Himalayan cedar.

This ancient, deciduous tree is found all over Asia. It grows in Japan, Korea, southern China, and Himalayan regions such as eastern Afghanistan, northern Pakistan, northern India, and southwestern Tibet and Nepal. It is also grown in Thailand for reforestation efforts.

The tree grows 10-30 meters tall and bears edible fruits which are dried out and taste like raisins. Its leaves are glossy, large, and pointed. 

Dihydromyricetin is extracted from the bark of the tree (source?). The extraction is then processed, dehydrated, powdered, then purified.

The second major source of the traditional medicine DHM is from the Ampelopsis grossedentata plant in the Vitaceae family. This plant is also known as Vine Tea extract or by the name of the tea it produces, moyeam. Moyeam tea is made from the leaves and stems of this plant and is popular in China.

The Ampelopsis grossedentata plant grows in southern and central China and other southeast Asian nations in high mountainous regions. The plant is largely produced in early summer and autumn. The leaves vary in type and shape but often appear thin, long, and needle-shaped.

The Tujia minority group developed the processing method for making tea 600 years ago. The leaves are picked, dried, rolled, and fermented. Other methods result in a powder that can be consumed after purification.

Who uses DHM?

DHM has a long history of being used in herbal Ayurveda and has been used for thousands of years for therapeutic applications throughout Asia. DHM’s many natural benefits have made it famous in traditional medicine.

The Japanese, Chinese, and Koreans have used dihydromyricetin as a hangover cure since the year 659. It has been used for so long in ancient Asia that is seen as a spiritual tree and even been called ‘tree of the gods’.

Scientific research starting in 2007 has introduced the health benefits of DHM to the larger western world. Promising results from double-blind tests on rats, mice, and humans have led to an increased usage of dihydromyricetin as a supplement to fight hangovers.

DHM entered the world stage in 2012 after a famous study done by Jing Liang an associate professor from the UCLA School of Medicine. Now dihydromyricetin is used by thousands of people every day who wish to protect their liver from the harmful effects of alcohol consumption and have nearly zero hangover side effects after enjoying a night out on the town.

What are the benefits of DHM?

There are countless benefits of using DHM as a supplement. These are some of the most notable benefits of dihydromyricetin:

  • helps the body break down acetaldehyde, a toxic product of alcohol metabolism
  • prevents damage to the liver
  • counteracts effects of acute alcohol (EtOH) intoxication.
  • speeds up recovery from hangovers
  • relieves alcohol toxicity
  • GABA/alcohol receptor inhibitor
  • treats fevers, rheumatism, physique, and diuresis
  • prevents anxiety
  • promotes sleep and concentration

    This is why DHM has been called a hangover cure and a “novel anti-intoxication medicine”

What are the risks of DHM?

DHM is safe for human consumption.

Taking DHM does not allow you to drink more alcohol. Alcohol should always be consumed responsibly and according to government health organizations’ guidelines.

Dihydromyricetin does not eliminate the dangers associated with heavy or irresponsible consumption of alcohol. 

Which studies and articles back DHM use?

Jing Liang’s 2012 study on mice getting drunk while using DHM is the most notable study which showed there was real science behind counteracting acute alcohol (EtOH) intoxication. You can find that study here:
