This kind of substance have various peculiar effects such as scavenging free radicals, anti-oxidation, anti-thrombosis, anti-tumor, anti-inflammatory, etc.. As a special flavonoid compound, in addition to the general characteristics of flavonoids, dihydromyricetin has the following characteristics:

  1. The general flavonoids are nearly insoluble in water, soluble in ethanol (alcohol), while dihydromyricetin is easily soluble in hot water, which means that dihydromyricetin in vine tea can be soaked out with boiling water with better benefits;
  2. In addition to the role of general flavonoids, dihydromyricetin also has the effects of relieving alcoholism, preventing alcoholic liver and fatty liver, inhibiting liver cell deterioration, and reducing the incidence of liver cancer;
  3. Dihydromyricetin has a small molecular weight (320), which makes it easier to pass through the blood-brain barrier and quicker to take effect.

Rattan tea is called the "king of flavonoids"

Rattan tea extract pharmacological efficac. According to the Chinese Pharmacopoeia, the total flavonoid content of these substances' comparison with rattan tea are as follows:
                    Flavonoid Content            Multiples
Rattan tea            36%—45.1%                    /
Ginkgo biloba         0.40%                        110
Propolis              1.0%                         45

Dihydromyricetin has significant effects in cleansing blood, reducing blood viscosity, anti-thrombosis, and clearing blood poison. According to The research progress of the pharmacological action of Dihydromyricetin, dihydromyricetin has the following effects:

  1. Dihydromyricetin is a strong antioxidant that can effectively eliminate oxygen free radicals in the body. Its antioxidation can prevent cell degradation and aging, and can also prevent cancer.
  2. Dihydromyricetin can improve blood circulation, lower cholesterol to greatly reduce the incidence of cardiovascular and cerebrovascular diseases. It can also improve cardiovascular and cerebrovascular diseases.
  3. Dihydromyricetin has been proved to reduce blood glucose by 26% and glyceryl triglyceride by 39% in animal experiments. It has a good effect on retinopathy and capillary embrittlement caused by diabetes.
  4. Dihydromyricetin can inhibit the exudation of inflammatory biological enzymes, and improve wound healing and pain relief. It has strong anti-histamine property, which can be used for all kinds of allergies.
  5. Dihydromyricetin has anti-tumor and anti-cancer effects. It has dual functions of prevention and treatment, not only for the tumor but for 14 kinds of cancers such as liver cancer, lung cancer, and stomach cancer.
