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.
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.
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.
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.
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.
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.
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.
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.
Dihydromyricetin (DHM) is a completely safe and natural supplement. It is non-toxic and presents no side effects when consumed at doses even far exceeding what is recommended.
Dihydromyricetin is one of the only candidates for treating alcohol use disorders that doesn’t have major side effects. One animal study that attempted to find toxicity failed to find any side effects at oral doses up to 22 g / kg of body weight in mice, a dose that far exceeds what is needed to enjoy its benefits.
