The fruiting body is usually up to 4 inches (around 10 cm) long and .2 inches (1/2 cm) wide. Unlike a typical mushroom, these are curved and club shaped like a small cane. They're usually orange or brown.
Kidney damage caused by the drug amikracin. Early research shows that using cordyceps with the drug amikracin might reduce kidney damage caused by the drug in older people.
Asthma. Early research suggests that taking cordyceps alone can reduce asthma symptoms in adults. However, other early research suggests that taking cordyceps along with other herbs for 6 months does not reduce the need for medication or improve asthma symptoms in children.
Chemotherapy. Early evidence shows that taking cordyceps by mouth during or after chemotherapy might improve quality of life and improve tolerance to the treatments.
Chronic kidney disease (CKD). Early research suggests that taking cordyceps along with standard therapy for chronic kidney disease may improve kidney function. However, most of these studies are low quality and were conducted for only 6 months or less.
Kidney damage caused by contrast dyes (Contrast induced nephropathy). Some early research shows that taking cordyceps while undergoing an exam using contrast dye reduces the chance of kidney damage caused by the dye. But other early research shows no benefit.
Kidney damage caused by the drug cyclosporine. There is early evidence that taking cordyceps with cyclosporine can reduce kidney damage caused by cyclosporine in people with kidney transplants.
Hepatitis B. Early evidence shows that taking cordyceps by mouth might improve liver function in people with hepatitis B. However, cordyceps seems to be less effective than the supplements astragalus and polygonum (fo-ti).
Sexual desire. Early research suggests that taking a specific cordyceps product (CordyMax Cs-4) daily for 40 days can improve sex drive in people with low sex drive.
Kidney transplant. Early research shows that taking cordyceps with low-dose cyclosporine can improve 1-year survival, prevent transplant rejection, and reduce the risk of infection similar to taking standard dose cyclosporine in people who received a kidney transplant. Also cordyceps seems to improve kidney transplant survival, kidney transplant rejection, and infection similar to azathioprine when taken with medications to prevent organ rejection. It might also reduce the risk of long-term impaired kidney function called chronic allograft nephropathy. This is the leading cause of kidney transplant failure.
