The content of cordycepic acid in Cordyceps militaris is 3.09 grams, and that in wild Cordyceps militaris is 5.54 grams. Cordycepic acid is a D-mannitol, which can increase the osmotic pressure of plasma, lead to water in tissues entering blood vessels, thus reducing tissue edema and replenishing plasma.
