The dried fruiting bodies of Ganoderma lucidum are used as medicine, including Ganoderma lucidum and Ganoderma rubrum. Ganoderma lucidum lipopolysaccharide has a wide range of immunomodulatory activity and can improve the body's immune activity. The triterpenoids isolated from Ganoderma lucidum fruiting bodies, Ganoderma lucidum polysaccharides, and Ganoderma lucidum spores all have anti-tumor effects. The proteoglycans in Ganoderma lucidum have antiviral activity, and the acid-bound Ganoderma lucidum polysaccharides have anti-herpes virus activity. Ganoderma lucidum triterpenoids can also resist HIV. Ganoderma lucidum phenolic compounds extracted by methanol and Ganoderma lucidum aminopolysaccharide G009 have antioxidant and anti-aging effects. Ganoderma lucidum polysaccharides can protect the liver and improve the ability to tolerate hypoxia. In addition, Ganoderma lucidum can reduce blood viscosity, increase myocardial contractility, increase coronary blood flow and cardiac output, and improve heart rate; it can also resist the damage of radiation and toxic chemicals to the body, has sedative and analgesic effects, prolongs sleep time, improves sleep quality, and can relieve asthma, cough, expectorant, and treat chronic bronchitis.
