The main effective components of this product are the extracts of wild cowberry, grape seed, blueberry and other plants, and their functions and effects are as follows: Grape seed is the seed of mature grapes, and generally grape seed comes from the leftovers of wineries, and the product is obtained by separating grape skins and grape stems after drying. Grape seeds are rich in protein and crude fat, and each kilogram of grape seeds contains choline: 279mg；; 2mg； hydrochloric acid; Pantothenic acid 34 mg；; .17 mg vitamin B1; Vitamin B22.5 mg. Grape seed contains 18 kinds of amino acids, such as aspartic acid, threonine, glycine and arginine, as well as a variety of minerals and trace elements. Grape seed extract contains polyphenol mixtures such as proanthocyanidins, anthocyanins, quercetin and resveratrol, which have various biological activities. The main effects of these mixtures on the eye and surrounding tissues are: strengthening the blood circulation of eye tissues can enhance the microcirculation of retinal capillaries and peripheral capillaries. In Europe, in order to improve blood circulation, treat diabetic retinopathy, relieve edema and inhibit varicose veins, anthocyanins have been used in clinical treatment for decades. Anthocyanin can strengthen capillaries, arteries and veins, so it has the effect of reducing swelling and removing blood stasis. The resistance of capillaries is reduced and the permeability is improved, which makes it easier for cells to absorb nutrients and eliminate waste. Transport nutrients and transport wastes, which are the functions of the blood circulation system. The heart is responsible for pumping blood; Arteries and veins transport blood; It is capillaries that are responsible for transporting nutrients to cells and transporting waste. Anthocyanins can scavenge water-soluble and fat-soluble free radicals in cell membranes, thus inhibiting the process of releasing some enzymes to damage capillary walls. The nourishing effect of anthocyanins can be observed in a short time. Professor HenriChoussat of the University of Bordeaux, France, conducted an experiment in which 47 people, aged from 37 to 85, each took 1 mg of anthocyanins. After 27 hours, it was found that the capillary resistance decreased by 4%. Anthocyanin can maintain the health of blood vessels and improve microcirculation, so that various organs and tissues can obtain adequate blood supply. It also improves the state of capillaries and enhances the blood circulation of cells around the eyes, so it is the hair follicle that gets more nutrients. Protecting and improving vision Diabetic retinopathy is a symptom of diabetes, which is caused by capillary micro-bleeding in the eyes and is a common cause of adult blindness. France has allowed anthocyanins to treat this disease for many years. This method significantly reduces the capillary bleeding of eyes and improves vision. Anthocyanins have also been used to prevent complications after cataract surgery in diabetic patients. In 1998, experts chose many people without eye diseases to do experiments to see if anthocyanins could alleviate night blindness. Participants were divided into two groups, one was the driver who drove at night, and the other was the person who spent all day with the computer screen. After four weeks, their blindness tolerance was checked again, and 98% of the subjects improved. The research and development of procyanidins in promoting hair growth is reported late, especially in Japan. Mainly because it has the function of proliferation and regeneration of hair follicle cells, which can promote hair growth and regeneration. Japanese scholars have found that 1% oligomeric proanthocyanidins can regenerate the hair of mice that have been shaved or whose hair has stopped growing. Now there are products available. U.S. Patent 612694 studies the hair growth promoting agent containing proanthocyanidins. In 1997, it was reported that black hair dye could be made from germanium-containing tannins and water-soluble iron salts. Promote the growth of hair follicle tissue cells. In 1 9 9 8, T a k a h a s h i et al. screened about 1 kinds of plant extracts, and found that proanthocyanidins extracted from grape seeds have obvious proliferation effect on mouse hair follicle cells and can promote mouse hair growth. Isatis indigotica extract: Isatis indigotica, Isatis indigotica of Cruciferae, is a biennial plant, also known as Isatis indigotica, Isatis indigotica, etc. Biennial herb, native to China. Isatis indigotica is a heat-clearing and detoxicating drug, which contains a variety of amino acids, sitosterol, indigo, indirubin and other medicinal components. It has the effects of clearing away heat and toxic materials, cooling blood and removing spots, and has good preventive and therapeutic effects on a variety of bacterial and viral diseases such as influenza, meningitis, mumps, leptospirosis, pneumonia, hepatitis and so on. Isatis indigotica has inhibitory effect on many kinds of bacteria. The aqueous extract has inhibitory effects on Bacillus subtilis, Staphylococcus aureus, Streptococcus octodipus, Escherichia coli, Salmonella typhi, Bacillus paratyphi, Shigella flexneri, Enterobacteriaceae, etc. Acetone leaching solution has a similar effect, and it is effective for hemolytic streptococcus (all by agar small hole plate method). Isatis indigotica can detoxify, reduce fire, effectively eliminate toxins in the body, improve human immunity, resist infection of bacteria and viruses, and balance yin and yang. It is reported that Radix Isatidis, Rhizoma Coptidis powder and Veratrum nigrum for dogs (2.g/kg each) can detoxify Veratrum nigrum and reduce the mortality rate. If veratrum is used again after poisoning, it is invalid; Using Radix Isatidis powder or Rhizoma Coptidis powder alone, the effect is not good either. In addition, Isatis indigotica is rich in basic fatty acids and effective ingredients for promoting hair follicle activation, which can quickly penetrate into hair follicles, continuously release rich nutrients, activate SOD activity in hair follicles and promote hair growth.
