Asthma is a chronic inflammatory disease of the airways involving a variety of cells, including inflammatory and structural cells and cellular components of the airways, manifested by recurrent episodes of wheezing, shortness of breath, chest tightness, or coughing, which often flare up and worsen at night and/or early in the morning. It is well known that asthma is highly prevalent and harmful. Many patients do not have effective control of their disease due to irregular treatment, and it can easily develop into diseases such as emphysema and pulmonary heart disease…. Severe asthma is critical and complex and must be rescued in a timely and reasonable manner and should be hospitalized immediately. For this reason we must pay more attention to remission treatment, with the aim of consolidating the efficacy, preventing or reducing recurrence and improving respiratory function. Self-blood meridian injection therapy (self-blood acupuncture) belongs to one of the external treatment methods of Chinese medicine, the main purpose of which is to consolidate the efficacy of asthma treatment and prevent acute asthma attacks. This therapy is developed according to the meridian theory and the principle of drug treatment, through the dual action of acupuncture and self-blood. For this reason we give a brief introduction to this kind. How is self-blood meridian injection therapy performed? ”Self-blood meridian injection therapy is an acupuncture treatment in which the patient’s own venous blood is drawn and injected immediately into specific acupuncture points on the patient’s body for treatment. One pair of acupuncture points with the same name is injected every other day, and every 5 times is a course of treatment. What are the effects of self-blood? Blood contains blood cells, tonic, enzymes, hormones and trace elements. Blood injected into acupuncture points stimulates and regulates the body’s immune function through absorption, generates lasting stimulation, promotes the release of more immunoglobulins, enhances microcirculation, antagonizes histamine and other active substances, inhibits It enhances microcirculation, antagonizes histamine and other reactive substances, inhibits metamorphic reactions and reduces capillary permeability. Which acupuncture points to choose for treatment? Asthma acupuncture injection formulas mainly have two types of acupoints, one is the acupuncture points for attack control, such as Tiantu, Tanzhong and Yuzhong, which can inhibit the release of allergic mediators, anti-inflammatory and improve the microcirculation of bronchial and pulmonary vessels, release the spasm of bronchial smooth muscle, and play a more lasting effect on asthma; the other is the dorsal points with tonic effect, which is the place where the essence of the internal organs is cohesive, and the three points in the dorsal points, namely Lung Yu, Spleen Yu and Kidney Yu, can adjust the yin and yang of the internal organs. The three points of Lung Yu, Spleen Yu and Kidney Yu can adjust the yin and yang of the internal organs, and achieve the function of tonifying the lung, strengthening the spleen, benefiting the kidney, and removing phlegm from the turbidity. What is the time of meridian injection? Asthma attacks have certain seasonality. Spring and irregular attacks can be treated after spring, while summer, autumn and winter attacks can be treated in summer and autumn respectively. At present, according to the theory of “winter disease and summer treatment” in Chinese medicine, the treatment of asthma by acupuncture point patching on three volt days has become an important way to prevent asthma attacks in winter, so it is also possible to use self-blood meridian injection with the patching of Chinese medicine to treat bronchial asthma at the same time. The two methods together can achieve the purpose of strengthening the root, enhancing the body’s resistance to disease and preventing the recurrence of asthma. What are the side effects of autologous blood acupuncture point injection? Autologous blood injection uses the patient’s own blood and does not contain any other drugs, so there is no contamination or rejection, so there are very few side effects, except for a little pain at the injection site, no significant adverse reactions. However, care should be taken to keep the injection site dry and clean, as contamination may also cause local infection, but the incidence is very small. At the same time, only one pair of acupuncture points is selected for each injection, and the cost is quite small, which does not increase the financial burden of patients and is really simple and inexpensive.
