This mushroom, Cordyceps sinensis also known as the Chinese catepillar mushroom or Dong chong xia cao meaning water insect has been used for centuries. There is much written about the historical aspects of this mushroom. It is considered an adaptogen. I have used it with the other adaptogenic herbs for a variety of conditions
Some of the properties are the following:
antiasthmatic
antileukemic
antioxidant
hepatoprotetcive
immune system boosting
nephroprotective
I usually prescribe as a tincture or in powder form. I find it very safe and effective. I use it extensively in lung patients to improve lung function. I used it as a immune booster during the recent COVID pandemic
