Fungi produce many useful medicines and antibiotics. Alexander Fleming first discovered penicillin from the fungus Penicillium notatum in 1944. Other antibiotics obtained from fungi include cyclosporine from Tolypocladium inflatum, used to prevent organ transplant rejection. Fungi also produce statins like lovastatin from Aspergillus terreus and the oyster mushroom, used to lower cholesterol. Ergot fungi contain alkaloids used to induce childbirth and treat menstrual disorders. Various fungi can synthesize steroids like cortisone. Many edible mushrooms have anti-cancer, anti-inflammatory, and immune-boosting properties.
