Gallnut extract is a product extracted from Gallnut, mainly containing Gallnut tannin, gallic acid and so on. Tannin and gallic acid and other components have a structure with more ortho-phenolic hydroxyl groups, which release hydrogen as a hydrogen donor to combine with free radicals in the environment, terminate the chain reaction caused by free radicals, and prevent the continued transmission and progress of the oxidation process. , so it has a strong effect of scavenging free radicals in the organism, thus producing an anti-aging effect. At the same time, due to the removal of free radicals, it protects the damage of biological macromolecules induced by free radicals, maintains the flow of cell membranes and the conformation of proteins, and prevents DNA breakage induced by radiation, thereby inhibiting lipid peroxidation, cardiovascular disease, and anti-aging. Mutation, anti-cancer, anti-cataract and other unique effects.

1. Convergence
Gallic tannins can combine with proteins to form water-insoluble macromolecular precipitates. After the skin, mucous membranes, and ulcers come into contact with tannins, their tissue proteins are coagulated, forming a layer of film and showing astringent effect. At the same time, small blood vessels are also compressed and contracted. Coagulates blood and has hemostatic effect. The protein of glandular cells is coagulated to cause secretion inhibition, resulting in dry mucous membranes and protein precipitation at nerve endings, which can be a weak local anesthesia phenomenon.
2. Antibacterial effect
Gallnut extract is effective against Gram-negative bacteria such as Pseudomonas aeruginosa, Shigella, Proteus, Escherichia coli, Bacillus aerogenes, typhoid bacillus and Staphylococcus aureus, Staphylococcus albus, Streptococcus beta, Diplococcus pneumoniae, Diphtheria bacillus , Bacillus anthracis and other Gram-positive bacteria have varying degrees of inhibition. It also has a strong inhibitory effect on certain pathogenic fungi. It has inhibitory effect on influenza A PR8 strain virus inoculated in chicken embryos. Its antibacterial mechanism is related to the coagulation effect of the contained tannin on the protein. In addition, it is also related to other components. Galla liquid still has antibacterial effect after removing the tannin.
3. Anti-fertility effect
100% Gallic Glycerin Solution has a good spermicidal effect, so this product has a certain anti-fertility effect.
4. Hepatoprotective and antioxidative effects Gallic tannic acid can prevent the nitration of aminopyrine in the stomach, and has a significant antioxidative effect, and may have an inhibitory effect on the carcinogenic process of nitrosamines. Intragastric administration of gallic acid has a protective effect on acute liver injury caused by CCl4.
5. Anti-ulcer effect The compound Galla galla extract, which is mainly composed of gallnut extract, can significantly reduce the amount of bleeding, shorten the bleeding time, and significantly reduce the secretion of gastric juice and gastric acid on gastric mucosal bleeding.
6. Inhibitory effect on smooth muscle
Gallic acid and esters can inhibit the astringent effect of bradykinin on the ileum of guinea pigs.
7. Detoxification
Galla tannins can form insoluble complexes with many heavy metal ions, alkaloids and glycosides, and have detoxification effects, so they can be used as chemical detoxification agents. The hydrolyzed tannin in gallnut also has the function of reducing the content of uremic toxin in the blood of patients with renal failure.
