The correct drug name of Cordyceps is Cordyceps sinensis, as a traditional Chinese medicine, there may be potential hazards, and the Chinese Pharmacopoeia 2020 Edition clearly points out that it is prudent to take Cordyceps for a long time, so it is not recommended to drink Cordyceps in water every day. Cordyceps is the dried complex of the fungus Cordyceps sinensis parasitized on the larvae of the bat moth family and the carcass of the larva, which has the effect of tonifying the kidney and benefiting the lungs, stopping bleeding and resolving phlegm, and is able to improve or treat the conditions of kidney deficiency and essence deficiency, impotence and spermatorrhea, lumbar and knee soreness, prolonged cough and weak asthma, and coughing and blood hemoptysis. The 2020 edition of the Chinese Pharmacopoeia clearly states that it is prudent to take Cordyceps for a long time, and it is generally not recommended to drink Cordyceps in water every day in order to be safe. It should be noted that people with superficial evils (evils on the surface of the muscles) should not use Cordyceps sinensis, nor should they drink water with Cordyceps sinensis, as its adverse effects are not yet clear. In addition, the tea made of Cordyceps sinensis can precipitate limited medicinal ingredients and cannot replace drugs to treat diseases, so do not use Chinese herbs to make water for drinking by yourself. Chinese herbs should be under the guidance of a doctor’s diagnosis, do not use indiscriminately.
