There are various ways to eat Cordyceps, such as making tea, decoction, making wine, cooking with food, and grinding into powder. All of these ways of eating Cordyceps can be used, but the best way to absorb and consume Cordyceps is to make a decoction and grind it into powder. Decoction is the traditional method of taking Chinese medicine, which has been recognized by the Chinese medical community, using water as a solvent to make the active ingredients of Cordyceps dissolve into the water as much as possible after boiling, so that it can be absorbed by drinking water. Grinding Cordyceps into powder can increase the absorption rate of the herb, so this is also a common way to eat Cordyceps. It is not recommended to swallow the powder directly, it is best to take it with boiling water, and to seal the lid of the water cup for 15 minutes, which can play a certain role in sterilization.
