Urticaria is the result of temporary exudation of plasma from the dermal vessels and is characterized by temporary, pruritic wind clusters that are caused by dermal edema. Most patients with chronic urticaria have symptoms that disappear within 2 years. Patients with a long history and combined physical urticaria are not easily cured. Removal of the cause and aggravating factors, especially medications, is very important. The commonly used treatments are divided into three lines, that is, from the most conventional to the least conventional methods. First-line approaches H1 receptor antagonists without sedative effects. Most of the drugs are effective in patients, but there is a lack of high quality comparative studies. Second-line approaches Leukotriene receptor antagonists, diet therapy, corticosteroids, H2 receptor antagonists, clearance of spirochetes, doxepin, nifedipine, PUVA, salazosulfapyridine, warfarin, stanozolol, tranexamic acid, dipyridamole, and thyroxine. It may improve the quality of life, but it does not change the cycle of urticaria. Strict dietary control is effective for some chronic urticaria. Third-line approaches Cyclosporine, plasmapheresis, intravenous immunoglobulin, mescaline, tacrolimus, omalizumab The first two approaches can be tried if treatment is ineffective, but the third-line approaches are unconventional therapies. And there is no guarantee of absolute effectiveness. Chinese medicine methods The above are all conventional treatments for urticaria internationally. Fortunately, there are Chinese medicine practitioners in China, so they can be treated with Chinese medicine therapies. The method we use is to use Chinese herbal medicine to identify the symptoms, together with oral calcium tablets. This method is more effective and at the same time ensures that there are no side effects.
