The liver is the largest hematopoietic bank and regulator in human body. In the face of modern people's excessive smoking and drinking, excessive medication (western medicine), the use of fruits and vegetables containing pesticides and food additives, serious environmental pollution, and toxins produced by the human body itself, the liver needs to effectively decompose, purify and excrete these toxins. Under fatigue, stress, decreased immunity, allergy, liver injury, chronic inflammation and other conditions, the original detoxification function of the liver declines, resulting in excessive deposition of endotoxin in the liver, resulting in chronic fatigue syndrome, which is characterized by soreness of the waist and knees, bitter taste and impatience.
