Reishi is thought to support and promote cardiovascular health and Traditional Chinese Medicine practitioners use it for the treatment of coronary artery disease. Phyllis Balch states in her book “Prescription for Nutritional Healing” that reishi is used to prevent high blood pressure and heart disease, lower high cholesterol levels and improve blood flow to the heart. Reishi also helps to prevent blood clots by keeping the blood thin and preventing it from clumping, a condition known as platelet aggregation.
Traditional Chinese Medicine uses reishi to slow aging; build resistance to disease; reduce inflammation; cleanse the blood; support liver, kidney and nerve function; enhance strength and stamina; and improve lower urinary tract function in men. It also is used to treat hay fever, insomnia, fatigue, viral infections, stomach ulcers, depression and impotence. These uses are based on anecdotal evidence, however, and not on solid scientific research.
