Years ago a friend with compromised immunity and chronic fevers HIV told me that reishi medicinal mushroom kept him out of the hospital. It balances the immune system for auto immune illness, restores energy and vitality and protects against infections (flu) and cancer. Anti-inflammatory for arthritis. Reishi Mushroom Extract has been used medicinally in China for centuries. It has a variety of health-promoting effects, including inhibiting platelet aggregation, lowering blood pressure, helping to normalize cholesterol and blood sugar. By helping to restore the immune system to balance, Reishi Mushroom Extract can have an effect on all parts of the body.
