Cordyceps has been widely used as an energizing "heal all" in Traditional Chinese Medicine for centuries. Of the many benefits, it was mainly used for fatigue, exhaustion, protection of the liver, improving kidney function, alleviating respiratory illnesses, and enhancing libido. It was also recommended for those with excessive stress, debility, weakness, and lacking strength (mentally and physically). Cordyceps is also used to improve energy, endurance, stamina, appetite, and disrupted sleep patterns.
