When will Western medicine catch up?
Herb/Drug Interactions: Some books recommend that cordyceps should be avoided by people who are taking immunosuppressive drugs such as cyclosporine (used to prevent organ transplant rejection) because it might interfere with the drugs’ effects. In a 1995 placebo-controlled study, sixty-nine people who had received kidney transplants were given cordyceps along with the pharmaceutical drug cyclosporine.
Not only did cordyceps not interfere with cyclosporine but it also helped prevent nephrotoxic (damage to kidney cells) side effects of the drug. Since that time more than five additional human studies have found that cordyceps given to kidney transplant patients allowed for
lower doses of cyclosporine, inhibited allograft rejection, protected liver and kidney function, reduced adverse drug effects, and reduced the incidence of infections (see the selected research studies below). Other studies found that cordyceps can help prevent nephrotoxic side effects from amikacin sulfate, prednisone, and gentamicin.
