Cordyceps is a fungus that lives on certain caterpillars in the high mountain regions of China. Most cordyceps supplements are made in a lab.
Cordyceps might improve immunity by stimulating cells and specific chemicals in the immune system. It might also help fight cancer cells and shrink tumor size, particularly with lung or skin cancers. Natural cordyceps is hard to get and might be expensive.
People most commonly use cordyceps for athletic performance, kidney disorders, liver problems, and sexual problems, but there is no good scientific evidence to support these uses.
