Rheumatism is mostly called “paralysis” and “paralysis”, which refers to the pain, numbness, flexion and extension of limb joints and muscles, and even deformation of joints or involvement of internal organs due to deficiency of vital energy, deficiency of liver and kidney, and the combination of wind, cold, dampness and heat that attack the body and paralyze the qi and blood. The disease is often chronic in course and lingering. It is often chronic and difficult to heal, and the three major causative factors of paralysis are deficiency of vital energy, external sensation and phlegm and blood stasis. Chinese medicine has a long history of treating rheumatic diseases, with many methods and various means. The overall treatment methods include dispelling wind and cold, warming the meridians and relieving dampness, clearing heat and detoxifying the blood, cooling the blood, removing phlegm and stasis, nourishing the liver and kidneys, strengthening the spleen and benefiting the qi, tonifying the qi and blood, and searching and clearing the channels. The application of worm medicine in the treatment of rheumatism has a very unique role, after generations of medical practitioners continue to practice and explore, and achieve good results. The application of insect medicine in rheumatism is part of the composition of animal medicine, its shape is small, and most of them are insects. Because it is “flesh and blood”, “insects fly away” products, has a unique medicinal properties, for generations of doctors pay attention to. (1) There are many insect medicines, which are able to penetrate the evil, search the wind and pass through the channels, and reduce swelling and pain. Later on, the medical practitioners of the Song Dynasty made further progress in the treatment of paralysis. Most of them have the ability to penetrate the evil, search the wind, relieve swelling and pain, dispel dampness and phlegm, and stop spasms and break blood. For the treatment of paralysis, some people believe that insect medicine should be preferred, such as the Qing Dynasty Ye Tianshi cloud: “wind, cold and damp three gas combined for paralysis, after years and months, the external evil stay, gas and blood are injured, into defeated stagnant phlegm, mixed with the meridians, must use insects to search, to move the medicine so that the blood does not clot, gas can be appropriate to pass. Therefore, he took the characteristics of “insects and ants that fly away quickly” and used them to treat paralysis by “making the flying ones rise and the walking ones descend, so that the blood is not clotted and the qi can be declared and cleared, so that the stagnant species in the ligaments can be searched and removed”. In his treatment of paralysis, he often used insects such as scorpion, centipede, dendrobium, dung beetle and dung beetle, advocating the use of blood circulation and insects to search and ventilate the meridians. 2, the clinical evidence of flexible identification (1) wind, cold, dampness, phlegm and stasis of the symptoms. The main worm medicines used in the treatment of paralysis are scorpion, centipede, dendron, beehive, silkworm, silkworm sand, white flower snake, earth turtle worm, pierced beetle, dung beetle, wuzhang snake, herb snake, cicada, snake molt, etc. Clinical application should be based on the respective worm medicines. The clinical application should be based on the characteristics of each worm medicine, combined with the characteristics of the clinical evidence, the diagnosis and treatment, and choose the best one to use. In general, the worm medicine for the treatment of paralysis can be divided into three categories: wind-damp-heat paralysis, the use of heat-clearing and wind-removing Di Long, stiff silkworm, silkworm sand, beehive. For wind-cold dampness paralysis, whole scorpion, centipede, and white flower snake are used. For paralysis and heat toxicity, use wuzhang, cicada, snake shedding, water buffalo horn, etc. For paralysis and stagnation, use turtle worms, piercing snail, leech. For all kinds of paralysis, we can choose wuzhu snake and herb snake. The salty taste and cold nature of Di Long can clear heat and stop spasms, dispel wind and open the ligaments, and is often used to treat heat paralysis, walking paralysis and stubborn paralysis. It is often used to treat heat paralysis, walking paralysis and stubborn paralysis. It is salty and sweet, good at dispelling wind and clearing ligaments, relieving pain and detoxification, and is used to treat stubborn paralysis; Silkworm is salty, sweet and flat, dispelling wind and clearing heat, dispelling phlegm and relieving spasm, and can be used for walking paralysis, heat paralysis and tendon paralysis. It can be used for damp-heat stubborn paralysis. The whole scorpion is pungent and sweet, warm and poisonous, can dispel wind and spasm, attack the poison and disperse the knots, go through the meridians, is the key medicine for the treatment of wind and phlegm, can treat wind-damp cold paralysis joint pain more intense. The centipede is similar to the whole scorpion in its effect on pain. Zhang Xichen said: “Centipede is the most rapid, internal and internal organs, external and meridians, where the Qi and blood cohesion can be opened. The two drugs together, external to the meridians, internal tendons and bones, can dispel wind, remove dampness, dispel cold and stasis, phlegm and pain, for generations of medical doctors respected. Both of them are suitable for rheumatism and paralysis caused by trauma, and the best one is used for pulse paralysis. The “Materia Medica Seeking Truth” says that it is “only good at scurrying, so it can reach the meridians, nowhere, and can enter the liver and stomach.” The white flower snake, herb snake, and wuzhu snake, all have the effect of searching for wind and clearing the channels, but the white flower snake is the most effective, the herb snake is second, and the wuzhu snake is less effective. The white flower snake is warm and poisonous, and can cure stubborn paralysis, but should not be taken for a long time. The herb snake is between the two, sweet, warm and non-toxic, and can be used for all kinds of paralysis. It can be seen that rheumatism has many clinical symptoms, so the application of worm medicine must be flexible to identify the evidence and pay attention to both. (2) Pay attention to the combination of addition and subtraction. Warming, clearing and tonic line elimination each other, complement each other. The clinical application of worm medicine, in addition to attention to the characteristics of each drug to give full play to its strengths, but also good with other drugs in close coordination, so as to improve clinical efficacy. For paralysis with cold and dampness, we use Ocimum sanctum and Silkworm, together with Chuan Wu, Gui Zhi, Cang Zhu and Hsiang Hsiang to disperse cold and dispel dampness. If the joint is stiff and swollen, use dung beetle, dung beetle and dung beetle, with Zeilan and white mustard to penetrate and disperse the swelling. Because of the dryness of worm medicine, when applying it, we should pay attention to the appropriate combination of nourishing Yin and nourishing blood to nourish the liver and kidney, such as Dihuang, Dendrobium, Shu Di Huang, Angelica, Bai Shao, Niubizi, Sequoia, Eucommia, Epimedium, Agaricus, Deer horn gum, Deer horn cream, Turtle shell gum or the formula of nourishing blood, such as Astragalus, Gui Zhi Wu Wu Wu Wu Tang and Si Wu Tang, to control its bias and prevent its blood depletion, so that it is dry but not hurt, nourishing but not greasy, to complement each other The effect.

The more rheumatic diseases treated by worm medicine in modern medicine include rheumatoid arthritis, rheumatoid arthritis, ankylosing crestitis, osteoarthritis, lumbago, systemic lupus erythematosus and dermatomyositis. The less applied ones include leukoarthrosis, adult Steele’s disease, etc. (2) Application of worm medicine for rheumatic diseases in dosage form. From the viewpoint of many doctors, soup is the most, followed by pills and powder medicine, and less for external use. Worm medicine should be made into pills, pills, tablets, etc., as far as possible, not only to save herbs, improve the efficacy, but also easy to take, reducing the patient’s unnecessary fear after seeing.

(7) Review the pros and cons, reduce toxic side effects. The use of worm medicine for rheumatism, we should pay attention to the observation that worm medicine is more dry, such drugs are served for a long time, easy to break the gas and blood, so it is appropriate to use one or three flavors, in addition to astragalus, the genus of ginseng to supplement the gas to help it search and expel evil, but also with angelica, peony, raw earth, yu zhu, huai yam, dan shen and other nourishing blood and nourishing yin products, in order to system bias, with each other to enhance the effectiveness.
