Chinese medicine’s understanding of the etiology of the disease is mainly based on the theory of the original deficiency and the symptoms of the disease, and it is believed that the internal causes are mostly caused by the dysfunction of the internal organs, among which the deficiency of the lungs, spleen and kidneys is the main cause; the external causes are mostly caused by the invasion of wind and cold and the evil of foreign qi. It is also believed that fire and heat are the causes of the disease. In the clinic the following causes are more common: 1, lung deficiency cold: the nose for the lungs of the orifice, the lungs are the main propagation, outside the skin. If the lung is not enough, the surface is not solid, the membrane is loose, it is easy for the wind and cold evil to take advantage of the deficiency and enter. The lungs feel cold, the lungs do not promote, the nasal orifice is unfavorable, thus leading to allergic rhinitis attacks. 2, lung and spleen deficiency: the lung is the main gas, and the spleen is the source of gas and blood biochemistry, the body gas generation, mainly dependent on the respiratory function of the lung and the transport function of the spleen. If spleen qi deficiency, often lead to lung qi deficiency. Lung Qi deficiency can also affect the transportation function of the spleen over time. Lung spleen qi deficiency, then fluid stagnation, and can be gathered and produce phlegm, over time stagnation of the nasal orifices and disease. 3, kidney deficiency: the kidney is the main water, the main gas, the root of the gas. The lungs are the source of water, and the lungs are dependent on the vaporization of the kidneys to promote and regulate the waterways. If the kidney is full of essence, the lungs will be warmed and nourished. If the kidneys are not enough, the qi does not return to the yuan, the intake does not have the right, the lung loses its warmth, the yang is easy to dissipate, and the nasal orifice is sick. In addition, some patients with allergic rhinitis have multiple causes, such as deficiency, deficiency fire or external wind-heat, or prolonged stagnation of Qi and blood. The symptoms of allergic rhinitis are manifested in the lungs, but the root cause is deficiency of the spleen and kidney. By warming the kidney and strengthening the spleen, tonifying the lung qi and improving the immune function, we can achieve the goal of eliminating allergic reactions.
