Cordyceps sinensis, commonly known as Cordyceps, is a fungus that has been a valued product of Traditional Chinese Medicine for thousands of years. It grows on the Tibetan caterpillar until the caterpillar dies, at which point the fungus sprouts a mushroom. In the West, Cordyceps is generally grown on plant sources such as soybeans for commercial use.
Cordyceps has been shown to act as an antioxidant and directly modulate the immune system. The traditional uses of Cordyceps include improving circulation, function of the lungs, heart, kidneys and liver. Cordyceps is also used to boost general vitality, increase longevity and improve sexual health.
