Pharmacology function: Antibiotic, antivirus, antitumor, resists hepatitis, suppresses the agglutinate production with plain B2 of thrombus of blood platelet. It can prevent low-density fat albumen from oxidizing, has the potential to prevent and cure cardiovascular disease, and gives protection against cancer, antivirus, and immune regulating the action; its function is shown as its anti-oxidant characteristic mainly.
Clinical practice: Used in the acute jaundice type infective hepatitis, blood silt, menorrhea, rheumatism type arthralgia, muscle bone-ache, sand drench, blood drenching, bronchitis, damp and hot gall stone; It is too high to be used in the cholesterolemia and triglyceride; It is anti-oxidant to be used in, slowed aging.
Security: It measures the protection of resveratrol by the extent of damage caused by the leucocyte release of lactic acid dehydrogenase enzyme to the cell. We find that its LD50 weighs 1000mg of each kilogram. The size of resveratrol between 5*10-7 and 10-3M causes lactic acid dehydrogenation of the enzyme to release lower than 7%. Making resveratrol has very high security.
