Chinese tea is well-known worldwide. But actually tea is also among the medicine in the field of traditional Chinese medicine. And vine tea is one of the tea herbs that can not just be eaten, but also taken as medicine. Growing in Enshi, Hubei in the southern part of China, vine tea contains 17 kinds of amino acids and 14 different microelements, which give the plant high medicinal value.
What is Vine Tea & What is Dihydromyricetin
Vine tea plant is one kind of rare typical tea plant, called as dragon-boat tea, dragon-whisker tea, young stem and leaf from Ampelopsis grossedentat, a plant growing in 1300-1950m hillside shrub or valley woodland , always be consider as legendary healthy tea. Researches show than vine tea can relieve inflammatory, mixture cough and antitussives, it also has strong inhibitory effect to common bacteria can be found in food.
“Chinese Herbal Medicine Collection” wrote that the vine tea (Teng Cha ) has a glycol flavor, the nature is cool; It can alleviate fevers and drunden, cure rheumatism, strengthen physique and many other functions. The vine tea (Teng Cha) contains rich flavonoids , amino acids, vitamins; Proteins and essential trace element, in which the content of total flavones, and Dihydromyricetin element are especially high.
Dihydromyricetin (DHM) is a natural extract of the vine tea plant. DHM has been used for centuries in traditional Chinese medicine as a hangover cure and intoxication blocker.
Some of flavonoids, for example Ampelopsin and Dihydromyricetin, are main active ingredients in vine tea, which have almost same MIC and MBC comparing with berberine, and have high Free radical scavenging activity varies between 73.3~91.5%. It can also reduce oxidative damage in the body, anti-aging, reduce the deformation and tissue necrosis of animal liver.
Dihydromyricetin also have ability on lifting alcohol poisoning, prevent for AFL, Inhibit the deterioration of liver cells, decrease the incidence of liver cancer. In these case Dihydromyricetin is consider as a good product for enhance activity of SOD, protecting liver and removing inebriation.
It also can be used in feed as antioxidant, controlling E.coli, aflatoxin, mold in the feed. Helps improving the taste and flavors of the poultry meat.

How Dihydromyricetin Works
There are two mechanisms of DHM which aid your body in dealing with the harmful effects of alcohol. The first mechanism requires a brief explanation of how your body processes and metabolizes alcohol. When you drink alcohol, it enters your bloodstream through your gut. Your blood is then filtered through the liver, where the alcohol is broken down (metabolized) and removed from your system - however, this removal process creates a very toxic byproduct known as acetaldehyde. Acetaldehyde is up to 30x's more toxic than alcohol.
Your body is able to break down both alcohol and acetaldehyde at a finite rate. Consuming alcohol beyond the rate at which your body can remove it causes an increase in your Blood Alcohol Concentration, or BAC, which causes feelings of intoxication.
However, drinking beyond this rate also means that your body is unable to process the acetaldehyde created by alcohol metabolism. This accumulation of acetaldehyde causes acetaldehyde poisoning, which is responsible for a host of hangover symptoms, including flushing and increased heart and respiration rates, severe abdominal and urinary tract cramping, hot and cold flashes, profuse sweating, and depression. Dihydromyricetin aids your body in breaking down acetaldehyde, so that less acetaldehyde accumulates in your system.
Alcohol, GABA and Glutamate
The second beneficial mechanism of DHM as related to alcohol consumption is a bit more complex. Understanding this second mechanism requires an explanation of how alcohol interacts with the chemical communication system of our brains - neurotransmitters. Alcohol crosses what is know as the blood-brain barrier, meaning it interacts with our neurotransmitters. This interplay of alcohol and neurotransmitters create the collection of feelings that we know as intoxication.
When you drink alcohol, it affects two of your neurotransmitters: GABA and Glutamate. GABA is an inhibitory neurotransmitter - meaning it lower mental excitement and muscle tension. As GABA increases you feel more relaxed. Alcohol binds to your GABA receptors, increasing their effectiveness. This is why alcohol lower your inhibitions and relaxes you.
Glutamate is the opposite of GABA - it's an excitatory neurotransmitter. As Glutamate increases, you become more excited. But unlike GABA, alcohol decreases the effectiveness of Glutamate receptors. This again leads you feel more relaxed.
As the alcohol in your bloodstream is metabolized, your brain seeks to return to its normal state. It floods your system with glutamate in a process known as glutamate rebound. Glutamate rebound causes a surge in excitatory feeling, sometimes leading to tremors, anxiety, restlessness, and even increased blood pressure. If you've been drinking at night, this rebound will occur while you sleep, which compounds the damage by making your sleep less restful. Even though drinking may make you tired, the sleep that you get is not restful, and is often punctuated with a sudden and premature wake in the morning.
Dihydromyricetin has been shown to inhibit alcohol's effect on the GABA receptors, thus naturally leveling out your system, and decreasing the amount of glutamate rebound. This means that taking Dihydromyricetin before bed allows your sleep to be more restful, in addition to decreasing feelings of anxiety and restlessness the next day.
What is The Function of Dihydromyricetin
1) Liver Protection
Dihydromyricetin has the strong inhibitory action of the rise of ALT and AST in the blood Serum. It can low the total bilirubin in the blood serum. So it has the strong action of lowing the aminotransferase and jaundice. The vine tea extract can restrain the liver fibrosis in the rat. It helps recovery from drunk and greatly reduces hangover symptoms. Widely used in medicine preparation of respiratory tract infection and alcohol intoxication.
Dihydromyricetin doesn’t just prevent you from getting drunk, but can actually sober you up after a night of drinking. It does this in two primary ways:
It blocks alcohol’s effect on your GABAa receptors, preventing the increased effect of GABA from causing the negative symptoms commonly associated with drunkenness.
It causes the liver to metabolize alcohol more quickly, lowering your BAC and causing you to be fully sober more quickly.
Dihydromyricetin is the most effective hangover cure currently on the market, and when combined with the age old advice of staying hydrated, will prevent hangovers in almost everyone. Dihydromyricetin (DHM) isn’t just useful and counteracting intoxication or preventing hangovers, but also helps to reduce the liver toxicity caused by alcohol consumption. While numerous studies have reported on the liver-protecting properties of the hovenia dulcis fruit, a recent study identified Dihydromyricetin as the responsible compound.
DHM also restrains the absorption of alcohol in the gastrointestinal tract, causing less of the alcohol you consume to reach your brain in the first place.
2) Protects the Brain from Oxidative Stress
It is well established that consuming alcohol contributes to higher levels of oxidative stress in the brain. Luckily research has identified dihydromyricetin as a potent anti-oxidant. Taking dihydromyricetin after a night of drinking is an excellent way to offset the increases in oxidative stress caused by alcohol consumption.
3) Helps Mitigate Alcohol Withdrawal
One of the most exciting finds of recent research on DHM is that it may have potential for treating alcoholism by lowering the desire to drink. While more research is needed to confirm if it will be useful for this, a recent study has shown that DHM counteracts signs of alcohol withdrawal including tolerance, increased anxiety, and susceptibility to seizures.
4) Clearing the free radical in body and antioxidation
The vine tea extract can effectively level down the lipid peroxidation. It can prevent the oxidative damage of antioxidase in body caused by the free radical. Then it can improve the oxidation resistance of the human body. Used in food antioxidant and preservative.
5) Antibiotic Function
The vine tea extract has the strong inhibitory action of staphylococcus aureus and Bacillus subtilis. It also has inhibitory action of Aspergillus flavus, Aspergillus niger, penicillium and Alternaria. Dihydromyricetin has the inhibitory action of Staphylococcus aureus, Staphylococcus aureus(S. aureus) and Pseudomonas aeruginosa.
6) Reducing the levels of blood sugar and blood fat
Dihydromyricetin can reduce the blood fat levels in the mouse. It can decrease the damage to liver cells caused by the high blood fat levels and improve the antioxidation ability. At the same time, it can low the levels of high blood sugar.
The vine tea extract can effectively restrain the mouse pinna swelling caused by xylene. It can also restrain the writhing response in the mouse caused by acetic acid.
What is The Application of Dihydromyricetin
Dihydromyricetin is a type of flavonoid with high bioactivity, used to treat liver diseases, hangover and vascular sclerosis. It’s also used as an antioxidant and anti-inflammatory substance. It’s been widely used as antioxidants and preservatives in food, effective in reducing free radicals, inflammation and lipids, relieving cough and protecting your liver. It’s been applied to various industries: healthcare products, personal care products, food additives and feed supplements which help boost immunity, improve average daily gain, feed intake, and feed efficiency.
