"Is a blend of cordyceps sinensis and Hepialus armoricanus from the high elevation regions of China. This ""Chinese Caterpillar"" fungus has been used as an adaptogen (for ch'i) in traditional Chinese medicine for thousands of years. Its use in this country has been primarily confined to energy production dynamics with applications in athletic enhancement and Chronic Fatigue Syndrome (CFS*). Research has shown an increase in liver ATP:Pi (inorganic phosphate) ratio indicating more energy within the liver for metabolism. Other areas of benefit are increasing SOD (an overall antioxidant) activity, strengthening immune function, kidney function and improving glucose metabolism.* "
