The meridian theory is the unique basic theory of Chinese medicine, the meridian and the luo are inseparable, the meridian has a certain path, while the luo veins are intertwined, network the whole body, all the organs, organs, orifices and flesh and bones and other tissues of the human body into a unified organic whole. The “Introduction to Medicine”: “The meridian is also the path; the branch of the path is next to the luo”, the luo vascular is the branch part of the meridian, the luo vascular is divided from the meridian, and then subdivided layer by layer, in the form of a network throughout the body, according to a certain speed and regularity, the qi and blood fluids running through the meridian are transported, diffused, and infiltrated to the internal organs and the limbs and bones, playing The physiological function of “moving qi and blood while supporting yin and yang”. The skin is the periphery of the body and the largest organ, the skin is not only the place where the meridians pass, but also the skin is the largest distribution site of the ligaments. The skin is not only the place where the meridians pass, but also the place where the largest meridians are distributed. It is the pathological basis of many skin diseases and is also the characteristic change of many skin diseases in the middle and late stages of development. As a result, clinical treatment methods such as blood circulation and wind circulation have become the most common treatment methods for skin diseases. 1, from the complex treatment of stubborn skin diseases to pass for use (1) treatment of wind first treatment of blood, blood line wind since extinction: wind to cause skin disease is the first of the evil, called “the first thief”, wind often combined with cold, heat, damp, phlegm, blood deficiency, etc. to form a strong pathogenic disease, difficult to cure. The wind evil causes the disease by first injuring the Wei Qi, gradually entering the Ying Blood, from the surface to the inside, from superficial to deep, and eventually often blocking the meridians, blood vessels are blocked, and skin nutrition is impaired. Therefore, in the treatment, the early evil in the table is easy to remove and easy to disperse, but the later is easy to activate the blood and blood circulation, treatment of wind and blood, blood vessels are not open to the wind evil is difficult to drive, blood vessels are unblocked, the meridians and channels are smooth then the wind evil easy to extinguish. This is the simplest reason for treating the wind and first treating the blood. For example, chronic urticaria is a typical skin disease caused by wind, but in the treatment of the author often in the thorny mustard, windproof, cinnamon, ginger and other wind medicine application at the same time, adding angelica, chicken blood vine, red peony, Chuanxiong, Xu Changqing, lily of the valley and other blood wind medicine, blood circulation, treatment of wind and blood, blood and wind will be extinguished. The clinical efficacy is like a captive drum. In the treatment of psoriasis, unblocking the meridians and regulating the flow of qi and blood always carry out the whole process. In the early stage of wind-heat and blood-heat stagnation, we must think of the paralysis and obstruction of the disease. It is a positive help for the prognosis of the disease. For the late stage of hypertrophy of the skin lesions, the color is light, then often a lot of application of blood activation and blood stasis, through the pick meridian products. Such as commonly used angelica, chicken blood vine, whole worm, leech, turtle worm gentiana, wei ling xian, loofah, peach kernel, safflower, etc.. The application of the products for treating wind and blood often becomes the key to reversing the disease and removing the evil. (2) Invigorate the blood and promote water circulation, invigorate the blood to resolve dampness: dampness is a common causative factor of skin diseases, which can cause eczema, urticaria, nodular itchy rash, erythema nodosum and other diseases. In the treatment of dampness, commonly used light percolation of dampness, aromatic dampness method, bitter cold dry dampness method, but the author has a fondness for blood dampness, the author believes that the reason why water dampness does not transform, is because the meridians do not work, qi and blood stasis, dampness is no way out, the evil of water dampness is easy to enter the blood into the complex, the disease and qi and blood intermingled, do not activate the blood meridians can not be unblocked, the evil of water dampness will not be transformed. Activate blood and dampness and blood and water should be the most effective measures of treatment, in the treatment of chronic eczema, stubborn dampness in the process of gathering, this rule is always effective. The specific application, often to remove dampness stomach Ling Tang, Dioscorea Z seeping dampness Tang, Ermiao Wan, gentian diarrhea liver Tang of the damp, combined with the peach and red four things Soup, Blood Mansions and Blood Stasis Soup, Gui Zhi Fu Ling Wan and other blood circulation, strengthen the blood and dampness and blood and water efficacy, the effect as captive drum. 2, treatment of luo disease should be distinguished from deficiency, cold and heat The luo disease is characterized by blood stasis, activating blood circulation is the main method of treatment of luo disease, but the luo disease can not be cured by simply activating blood circulation and removing blood stasis, the reason is that the luo disease should also be distinguished from deficiency, cold and heat, the meridians and channels are smooth, the flow of qi and blood is the goal of treatment, distinguishing deficiency, cold and heat, targeted balanced conditioning is an important means. As a disease, the main reason is that the real one is evil, such as wind-cold, wind-heat, wind-damp, wind-phlegm, blood-heat, heat-poison, phlegm-stasis, blood-stasis, etc. blocking the skin and meridians, so the treatment should be based on eliminating evil. Because of the deficiency, blood deficiency, Qi deficiency, liver and kidney deficiency, essence deficiency, the disease is also formed. Treatment should follow the principle of eliminating the real and replenishing the deficient, adjusting the balance according to the situation, so that the diseased meridians can recover. In terms of specific application, for wind-cold evil blocking the ligaments, dispersing cold and opening up the ligaments is the first priority, and Gui Zhi Tang and Ma Gui each half of the soup are the most commonly used formulas. When the wind-heat evil obstructs the ligaments, the basic method is to clear the heat and remove the wind to open the ligaments. If the wind-dampness is blocking the ligaments, it is advisable to dispel the wind and overcome the dampness, which is often treated with Douwuxiaosheng Tang and Huoxiang Zhengqi San. Wind-phlegm is often developed on the basis of wind-dampness, wet refining as phlegm, wind-phlegm blocking the luo is the disease of the luo is more difficult to treat nodules, cysts, stubborn itching, treatment should be to dispel wind and phlegm, soften the hardness and disperse the knots. Commonly used to dispel wind and combine with Er Chen Tang treatment. In this way, we can clarify the deficiency and the actuality, and target the repair of the disease ligaments, so that the meridians can be opened, the qi and blood can be smooth, and the evil can be removed. 3, the external treatment of skin diseases caused by the disease complexes There are many kinds of skin diseases caused by the disease complexes, but they are always characterized by external hair, involving the skin, hair, nails, etc. “Surgical diseases, the most important external treatment”, which can directly reach the disease, the most rapid results. The external treatment of skin diseases treated by the disease complex, often with aromatic and pungent string of products, dredge the meridians, combined with the specific situation, or adjuvant blood nourishing and invigorating products, treatment of blood deficiency and blood stasis; or adjuvant warming and dispersing cold products, treatment of cold paralysis evidence; or adjuvant cooling blood detoxification products, treatment of toxic heat stasis evidence. However, the treatment of diseased ligaments is the key to pass through and repair is the goal. In terms of medicine, Cang Er Zi, Wei Ling Xian, Ai Ye and Chuan Geun Pi are commonly used drugs. Nourishing the Blood and invigorating the Blood is often coupled with henbane, safflower, sumac, and peach kernel, etc. As in the treatment of keratotic eczema, the lesions appear dry and hypertrophic, keratinized and desquamated, and chapped. Warming and dispersing cold is often combined with Hosanna, Cinnamomum, Ephedra, and Chuan Cao Wu, such as in the treatment of cold erythema multiforme and frostbite, where the symptoms include dark purple erythema, low skin temperature, and pale peripheral edema. The symptoms of cold erythema and frostbite include erythema in the form of plaques covered with white scales and infiltrated with hypertrophy. For specific application, fumigation, medicinal bath, soaking, wet compress, medicinal powder and other methods can be used. In conclusion, the theory of disease ligament has pioneered the treatment of intractable skin diseases and chronic skin diseases from stasis, and from the treatment of ligaments and repair of disease ligaments. We need time to further prove which skin diseases exist in which period and to what extent, and whether the methods we use to repair the disease ligaments are effective, so as to contribute to the modernization of Chinese medicine.
