Cordyceps fungi (Cordyceps militaris) or "Chong Cao Hua" is quite a fantastic fungi with a very mild taste. This wonderful fungus can be used is soups and different savory dishes. Cordyceps is good for the heart and lungs it can be used to reduce stress and strengthen the immune system. Fu Heng Herbs is an excellent source for quality chinese herbs and herbal products with great customer service and fast shipping. I would highly recommend.
