Cordyceps

A Chinese fungus used as a tonic and restorative. It is also known for improving athletic performance. You can buy whole, dried cordyceps in health food stores and add them to soups and stews, or drink tea made from powdered cordyceps, but it is more convenient to get cordyceps extracts in liquid or capsule form. To treat general weakness, take cordyceps once or twice a day, following the dosage advice on the product. For health maintenance, take it once or twice a week.
