Cordyceps contains bioactive compounds like polysaccharides and cordycepin, which have been shown to have immunomodulatory effects. Rather than simply boosting immune function, Cordyceps may help balance the immune system--enhancing immune responses when they are weak and suppressing hyperactive immune responses that are characteristic of autoimmune diseases.
Cordyceps can promote the activity of regulatory T cells, which help maintain immune tolerance and prevent the immune system from attacking the body's own tissues. In autoimmune diseases, regulatory T cells often fail to function properly, contributing to the disease process.
