Dryness syndrome is a group of chronic autoimmune diseases mainly involving exocrine glands throughout the body, with symptoms of salivary glands and lacrimal glands as the main cause. Clinical symptoms of dry mouth and eyes are due to inflammatory infiltration of lymphocytes between salivary and lacrimal glands, followed by atrophy and destruction of the glands. There is no similar disease name recorded in the TCM literature, and because of its complex and diverse clinical manifestations it may be assigned to a variety of disease names. For example, some doctors believe that the joint pain belongs to the category of “paralysis”; the accompanying damage to the internal organs belongs to “internal organs paralysis”; the lesion involves the whole body, so it is called “peripheral paralysis”; most people classify it as Most people classify it as “dryness”; modern medical doctor Lu Zhi-Zheng generalizes it as “dryness paralysis”, which seems to be more appropriate. The treatment of this disease mainly starts from the following entry points, which are often effective: from deficiency: mainly including Yang Qi and Yin liquid deficiency. Yang Qi deficiency is mainly in the spleen and kidney. The spleen is the main transporter, both transporting water and grain, and transporting water and dampness. If the spleen qi is deficient, the water and grain are not transported, the essence is not distributed, and the water-dampness is not transformed. Insufficient kidney yang, which cannot transpire and transform, can be seen as dry mouth and dry eyes. The treatment is to strengthen the spleen, benefit the qi and tonify the kidneys, commonly used in Sijunzi Tang, Kidney Qi Pill and so on. Insufficient yin fluid and lack of yin and fluid directly lead to dryness. In treatment, according to the lack of fluid in each organ, we can apply Sha Shen Mai Dong Tang, Yu Niu Decoction, Liu Wei Di Huang, etc. Treatment from dryness and toxicity: “Su Wen? Wu Chang Zheng Da Lun” said: “dryness is not enough, brewing into poison, decoction of fluids, Yin loss and gain dryness”. The occurrence of SS is due to the deficiency of Yin and Blood, Yang Qi, or internal heat, fire and other internal dryness, and often invaded by foreign warm and dry evil, thus forming a vicious circle of “dryness into poison, because of the poison and dryness”; warm and dry poison is not removed, the Yin deficiency and blood is difficult to restore, and the disease evil from the superficial into the deep, from the skin, the mouth, eyes, nose and throat and other clear orifices and The disease will be superficial and deep, from the skin and hair, mouth, eyes, nose and throat and other clear orifices to the internal organs. In the treatment of SS, clearing heat and detoxifying toxins is given first priority, and sweet-cold and cool moist medicines are preferred, such as honeysuckle, forsythia, dandelion, daidin, summer kucca, guanzhong, white flowered snake-tongue grass, cockscomb, genus ginseng, fleabane, half-branch lily, dendrobium, and grain jingcao. Start from stasis: Blood stasis can cause dryness, but also is the pathological product of dryness and secondary pathogenic factors. In Su Wen? In the treatise on paralysis, “When the disease is prolonged and deep, the movement of Ying and Wei is astringent,” indicating that chronic diseases are often related to blood stasis. In the book of “The Essentials of the Golden Killing”, it is stated that chronic diseases are often related to blood stasis. The sixteenth book on the treatment of pulse evidence of chest fullness and stasis of blood in palpitation and epistaxis has: “The patient’s chest is full, his lips are impotent and his tongue is green, his mouth is dry, but he wants to gargle water and does not want to swallow, there is no heat or cold, his pulse is slightly large and late, his abdomen is not full, and he says I am full, because he has stasis of blood.” It is mentioned that dry mouth can be caused by stasis of blood. Stasis of blood, blockage of Qi, and non-distribution of water and fluid can cause dryness. At the same time, deficiency of Yin and Jin, Jin does not transport Blood, and Blood flow is astringent and does not flow smoothly, resulting in stasis; dryness and toxicity over time injure Jin and consume fluid, and meridians are astringent and stagnant, and Blood flow does not flow smoothly, resulting in stasis; Qi deficiency and inability to promote Blood flow can also result in stasis, and the formation of stasis at the same time increases the “dryness”. Clinical prescriptions often use peach kernel, safflower, angelica, red peony, Wang Bu Liuxing, Andrographis paniculata, curcuma, etc.
