Material Overview
Vine tea is not only a pure natural green drink, but also a valuable tea with strong efficacy and health care properties. It contains protein, dietary fiber, fat, carotene, vitamins and iron, zinc, calcium, magnesium, potassium, sodium and other elements required by the human body, and has a unique effect on preventing excessive liver fire, pharyngitis, hypertension and so on. It also has the effect of clearing heat and detoxification, beauty and anti-aging, and can especially improve the quality of sleep for people with poor sleep quality.
Benefits
1. Antibacterial effect:
Dihydromyricetin has antibacterial effects on Bacillus subtilis, Staphylococcus aureus, Salmonella, Escherichia coli, Aerogenes, brewer's yeast, Rhodosaccharomyces mucus, penicillium, Aspergillus Niger, Aspergillus aflatus, mucor and rhizopus, especially on gram-positive and gram-negative coccus or bacillus.
2. Regulating effect on blood sugar and blood lipids:
Dihydromyricetin can significantly inhibit the rise of blood sugar, at the same time, the inflammatory reaction is significantly reduced, and the number of islets is significantly increased. Dihydromyricetin decreased the content of serum triacylglycerol (TG) in hyperglycemia rats induced by streptomycin, but had no significant effect on the content of serum total cholesterol (TC) and high density lipoprotein cholesterol (HDL2C).
3. Liver protection:
It has significant protective effect on liver injury. Dihydromyricetin can protect the liver, accelerate the rapid decomposition of ethanol metabolite acetaldehyde, become non-toxic substances, reduce its damage to liver cells. In addition, dihydromyicetin can improve the increase of serum lactate dehydrogenase activity caused by liver cell injury, inhibit the formation of hepatic M cell collagen fiber, thus playing a role in protecting the liver, greatly reducing the liver damage caused by alcohol, and rapidly restoring the normal state of the liver.
Main component of raw material
It is rich in flavonoids, amino acids, vitamins and essential trace elements. According to the nutrition analysis results of the Institute of Nutrition and Food Hygiene of the Chinese Academy of Preventive Medical Sciences, every 100g of product water 9.4g, heat 291 kcal, Main nutrients protein 20.4g, fat 0.8g, carotene 5.23mg, vitamin E6.32mg, iron 10.1mg, zinc 1.58mg, calcium 411.3mg, copper 0.67mg, magnesium 121.6mg, selenium 10.62μg, rich in flavonoids. Compared with the tea in the "Food Composition Table", its nutritional composition is more complete, better than the general tea, especially the content of brass compounds and selenium is much higher than that of green tea and scented tea. Rattan tea is rich in selenium, the element symbol is Se, which is an essential trace element for the human body.
Microherb test proved that dihydromyricetin can protect the liver, accelerate the rapid decomposition of ethanol metabolite acetaldehyde, become non-toxic substances, and reduce the damage to liver cells. Dihydromyricetin acts quickly and has a lasting effect. It is a good product for protecting the liver and removing alcohol.
4. Antioxidant effect:
The scavenging rate of diphenyltrinitrophenylhydrazine (DPPH) free radicals in the test system by 99% dihydromyricetin. Dihydromyricetin can significantly inhibit the formation of MDA in oil, and the antioxidant effect is enhanced with the increase of dihydromyricetin purity (60%-90%). It has strong antioxidant effect on animal oil and vegetable oil.
5. Anti-tumor effect:
In recent years, anti-tumor pharmacodynamics studies have found that one of its active components, small molecule compounds of ophiopsin, has relatively strong anticancer effects. In vitro and in vivo anti-tumor studies have found that the compound can improve the efficacy of tumor treatment and improve the life of patients by inhibiting the growth of tumor vessels, regulating and enhancing cellular immune function, etc. It has been shown to have obvious anti-tumor effects in tumor model studies such as leukemia and nasopharyngeal carcinoma.
Packaging:
Negotiate or use double layer plastic bags internally, 1kg aluminum foil bags, 25kg cardboard drum
Storage Store:
Place it in cool, dry, avoid light, avoid high temperature.
