note:

1, it is best not to wash the cordyceps before use, because washing will make the fungal spore powder attached to the fruiting body of the cordyceps with dietotherapy lose and affect the efficacy.

2. If you buy Cordyceps in bulk, many people don't look clean after contact. You can wash it before use, but don't soak it for too long.

3. Soup should not be cooked for a long time, so as to avoid the loss of fragrance and the destruction of nutrients.
