Schisandra is a fruit with five medicinal properties of pungent, sweet, sour, bitter and salty. It is unique among Chinese herbal medicines that generally only have one or two medicinal flavors. This fruit with all five flavors and five elements can play a balancing effect on the five internal organs of the human body - heart, liver, spleen, lung and kidney.
Schisandra chinensis is sweet and sour in taste, warm in nature, and has the functions of invigorating the kidney and calming the heart, invigorating Qi and promoting body fluid, strengthening the exterior and relieving sweat, etc.
1. Effects on the central nervous system
Schisandra chinensis has obvious sedative effects. Schisandra chinensis extract and alcohol methyl can reduce the autonomous activity of mice, prolong the sleep time of barbiturates, inhibit animal aggressive behavior, and resist electrical shock and chemical convulsions. The effects are similar to tranquilizers. There are analgesic and muscle relaxation effects.
2. Hepatoprotective effect
The alcohol extract of Schisandra chinensis and Schisandrin A, B, C, alcohol methyl, alcohol B, ester A, and ester B have obvious protective effects on animal liver cell damage caused by chemical poisons, can inhibit the release of transaminase, and make ALT active. reduce. Can significantly induce mouse and rat liver microsomal cytochrome P-450 activity. Increase liver detoxification capacity. Schisandra chinensis can also inhibit the carbon monoxide generated after CCl4 is metabolized by liver microsomes and the consumption of NADPH in the metabolic process.
3. Effects on the cardiovascular system
Schisandra has a vasodilator effect. Schisandrin, Schisandrin C, and Deoxyschisandrin all have inhibitory effects on the contraction of isolated dog mesenteric arteries, and can increase blood flow in isolated rat hearts and coronary arteries in anesthetized dogs. Feeding rabbits with Schisandra chinensis can regulate the energy metabolism of cardiomyocytes and cardiac and renal arterioles, increase the activity of myocardial metabolic enzymes, and improve the nutrition and function of the myocardium.
4. Anti-aging effect
According to the "Benjing", Schisandra "mainly replenishes qi, replenishes deficiency, strengthens yin, and benefits men's essence". Both schisandrin B and schisandrin have antioxidant effects, which can scavenge free radicals and inhibit the formation of lipid peroxides. Gavage of Schisandra chinensis aqueous extract to aged mice can significantly inhibit the activity of MAO-B in the brain and liver, enhance the activity of SOD, and reduce the content of MDA.
Schisandrin can directly antagonize the cardiac mitochondrial toxicity induced by adriamycin, and inhibit the lipid peroxidation of rat brain, liver, kidney microsomes and mitochondria induced by vitamin C-NADPH, and its effect is stronger than vitamin E. It can also significantly increase the cAMP content of aged rat cardiomyocytes, increase the cAMP/cGMP ratio, and enhance cardiac activity. In addition, Schisandra can reduce serum cholesterol and increase protein content in the brain and liver, all of which have been shown to have anti-aging effects.
5. Effects on the respiratory system
Schisandra chinensis can "receive lung qi" and "relieve cough and asthma". Animal experiments show that schisandra decoction and schisandrin have excitatory respiration. The acidic components of Schisandra can reduce neutral mucopolysaccharides and acidic mucopolysaccharides in the tracheal glands of mice, and have expectorant and antitussive effects. Schisandra can enhance the function of bronchial epithelial cells in mice with chronic bronchitis.
6. Effects on metabolism and immune function
Schisandra can promote the synthesis of liver glycogen, strengthen the metabolism of sugar, and increase the synthesis of protein in liver cells. It can promote the DNA synthesis of lymphocytes, increase the generation of lymphoblasts, and promote the immune function of the spleen. Schisandrin can enhance the immunosuppressive effect of adrenocortical hormones and can resist the rejection of allogeneic tissue transplantation.
7. Anti-ulcer effect
The gavage of Schisandra chinensis in rats can inhibit the occurrence of stress ulcer, reduce the ulcer index, and inhibit the secretion of gastric juice.
Side effects: Oral crude drugs above 13-18g may have hiccups, acid regurgitation, heartburn, bowel whimper, drowsiness, etc., and occasionally allergic reactions.
Poisoning reactions include: fever, headache, fatigue, dry mouth, a sense of ignorance, nausea, vomiting, urticaria, etc. Oral oral administration of Schisandra chinensis ether extract is equivalent to 13-18g of crude drug orally and may experience hiccups, acid regurgitation, heartburn, bowel whimper, drowsiness, etc.
Food taboos: schisandra, wolfberry, red dates, and ginseng will not have side effects when soaked in water. But medicine is always medicine. When you are in good health, you don't need to take it, and you can't take it if you have a cold.
