Cordyceps (Dong Chong Xia Cao)

Cordyceps (also known as ophiocordyceps sinensis) has been used in both Chinese and Tibetan medicine for centuries. A parasitic fungi that typically grows high in the mountains of Nepal and Tibet, cordyceps is highly prized for its tonic effects. 

It is said that cordyceps can boost testosterone and fertility, raise immune system function, regulate the liver, and fight cancer. It is also used to treat coughs, chronic bronchitis, high cholesterol, liver disorders, etc.[1] Cordyceps mushroom also has potent antioxidant properties[2].

 The medical research continues to grow for cordyceps sinensis. Some of the other benefits of cordyceps as tested in a clinical setting:

• Boost exercise performance^[3]
• Increase testosterone^[4]
• Cellular oxidative stress protection^[5]
• Combating altitude sickness^[6]
