Bacon: The human body takes water and soil as its root, and one side takes water and soil to support one side. Bacon's disease refers to various allergic diseases caused by acclimatization, such as allergic rhinitis, asthma, allergic gastroenteritis and allergic dermatitis. The ancient Chinese medicine book "Tujing" records that "Cordyceps sinensis can clear lung heat, treat lung disease and bacon disease". Cordyceps militaris has this effect completely.
