Acupuncture point injection has the following three major effects: First, amplification, that is, the same dose of drugs in acupuncture point injection produces a stronger effect than subcutaneous or intramuscular, or even intravenous injection, or to achieve the same effect, acupuncture point injection application of drug dose than intravenous, intramuscular or subcutaneous injection is small. Second, has a two-way regulatory effect, according to the relevant research found that different meridian points to different drug reactivity, the meridian points have a discriminatory nature of accepting chemical stimulation or acupuncture points to inject drugs have a certain recognition role, which is the drug to the meridian theory of performance, injected in the acupuncture points have a relatively specific drug, the taste of this drug and the meridian points have a special affinity, that is, to this meridian, it can On the contrary, if the drug injected into the adverse identification, the acupuncture point can weaken or correct this adverse effect. In short, acupuncture point injection when the meridian as a carrier, the drug transported to the corresponding area or part, so that the drug and meridian points play a two-way role, so that the drug effect is enhanced, and more rapid and lasting. Third, the triple effect, (1) immediate effect: produced within minutes and hours of needle entry, mostly caused by local stimulation by needling and drug injection; (2) slow effect, which can occur within hours to a day of treatment and is related to the biochemical action of the drug in the acupuncture point area; (3) after effect, which is achieved by mobilizing and restoring the patient’s own regulatory function on the basis of the first two therapeutic effects. This initial mechanical stimulation effect, which is obtained through the conduction of the acupuncture points for immediate effects, and the mid-term chemical effect of the drug and the later post-action effect, then bring into play the combined effect of the acupuncture points and the drug, which inevitably prolongs the validity of the therapeutic effect after acupoint injection and allows for more effective control of the disease during this longer treatment process. The onset and continuation of the drug effect during acupoint injection has the participation and coordination of the meridian point function. In this process, the special functions of affinity, meridian, direct access, pathogenicity, rapidity and prolongation of meridian points and drugs contribute to the high efficiency, rapidity and longevity of acupoint injections, so that acupoint injection therapy is simple and can be done every other day, or 1-2 times a week, or even once a month in some cases. Dermatology commonly used injection points and drugs are not bound to individual acupuncture points, according to the clinical evidence of the selection of the meridian, evidence of the selection of points, evidence of the use of drugs, Chinese medicine has “the first disease in the qi, long-term disease in the blood”, “treatment of wind first treatment of blood, the blood of the wind will be extinguished”, “long-term disease into the luo for the blood”, “the blood of the blood, the wind is extinguished, “In the selection of meridians and channels, we often choose foot Yangming Stomach meridian, foot Taiyin Spleen meridian, hand Yangming Large Intestine meridian, foot Sun Bladder meridian, and Governor’s vein, and in the selection of acupuncture points, we often choose Foot Sanli, Quchi, Diaphragm acupoint, Lung acupoint, Kidney Yu, Sea of Blood, Sanyinjiao, Dazhi, and Hundred Wormwood. In the acupuncture point injection drugs are often used antihistamines such as Benadryl injection, paracetamol injection, cimetidine injection, immunomodulators such as BCG polysaccharide nucleic acid injection, nutritional drugs such as vitamin B12, adenosine cobalamin, etc., whitening drugs such as reduced glutathione and some Chinese medicines such as dampicol injection, angelica injection, gastric injection, etc., can be one or several in a certain ratio with lidocaine The injection solution can be mixed with lidocaine and then injected into the acupuncture points. Acupoint injection has been used since the 1950s, and its efficacy on dermatological diseases has been clinically confirmed, which has not only enriched the clinical treatment of dermatology, but also its exact efficacy is a blessing to the majority of dermatological patients.
