Chinese medicine “treats from toxicity”, applying “detoxification method”, “detoxification method”, “anti-toxicity method” and other methods, providing a new theory and way for The method of “detoxification”, “detoxification method” and “control method” are applied to provide a new theory and way to prevent and treat respiratory diseases caused by air pollution. Detoxification method: Detoxification is to target the part of the poison and give the poisonous evil a way out by taking advantage of the situation. 1, the lung detoxification method: the lung in the body together with the skin, and its Hua in the hair. “Nei Jing” cloud: “skin and hair, the lungs also, the person’s Yang also.” “All diseases begin to be born also, must first in the skin and hair.” The skin and hair have the function of defending against external evil, regulating fluid metabolism, regulating body temperature, and assisting in breathing. The external poisonous evil invade the skin and hair, so that the skin and hair can not promote the lung qi, the breathing is not smooth. The Nei Jing calls the sweat hole “Xuan Fu” and “Qi Men”, which means that the sweat hole is the gateway to the excretion of sweat, and is also the part of the body that exchanges gas between the body and the outside with the propagation and purification of the lung qi. If the skin and hair are affected by evil, it can lead to poor sweat excretion and the accumulation of turbid gas in the lungs that cannot be expelled from the body, thus leading to the generation of diseases. This method is mainly applied to the evidence of poisonous evil in the surface, as stated in the Classics: “The so-called sweat is also a treatment for the surface evidence.” Therefore, in the treatment of disease, you can add drugs that promote lung sweating as appropriate, the method has two: cold guests should be pungent warm detoxification, such as ephedra, Elsholtzia, cinnamon branch, onion, pungent and other drugs; hot people should be pungent cool detoxification, available mint, burdock, cicada, mulberry leaf, yellow chrysanthemum and other drugs, so that the poisonous evil from the sweat discharge. 2, through the internal organs detoxification method: “lung and large intestine,” lung congestion, loss of suction, gas does not go down, fluid does not go down, can cause the internal organs, constipation, intestinal dryness. As the “Women’s Complete Good Formula? Volume 8” pointed out: “the lung is the main gas, lung gas does not descend, then the large intestine can not be transmitted.” Epidemic Rash? Volume 4: “Lung gas can not reach down, then the large intestine can not transmit the order, and the stool is also knotted.” As the degree of constipation or blockage in the stool increases, the duration of the disease is prolonged and the condition is aggravated. Therefore, in the treatment of pulmonary diseases should be used in the process of diarrhea, benefit Qi, blood and bowel movement, warming the Yang to detoxify the internal organs. Specific drugs can be used such as rhubarb, fire marijuana, astragalus, angelica, shouwu, cistanches, locking yang, etc., so that the poisonous evil can be eliminated from the body through the stool.
