Urticaria is commonly known as “rash”. It is often triggered by drugs (such as penicillin), food (mainly animal proteins), pollen and dust, infections, insect bites, and psychological factors. Itching of the skin is common, followed by the appearance of rubellae, which are bright red or pale white. The puffs gradually spread and may fuse with each other to form patches. Occasionally, large blisters may form on the bumps. Some patients have nausea, vomiting, headache, headache, abdominal pain, diarrhea, and some have systemic symptoms such as chest discomfort, pallor, rapid heart rate, weak pulse, decreased blood pressure, and shortness of breath. Urticaria caused by acute infection and other factors may be accompanied by high fever and increased white blood cells. (A) diet regimen method usually pay attention not to overeat, eat less beef, lamb, pork, fish, shrimp and other seafood, and drink less alcohol. Because after overeating, the peptone in the food will be absorbed into the blood through the gastrointestinal mucosa before being digested, which will cause redness of the skin, wind mass, accompanied by weakness and headache. Do not take suspicious food or medicine, and pay attention to whether the bowel movement is normal or not. If you develop hives from eating fish, shrimp, or crab, you can consume a large amount of fresh perilla leaves, or drink a decoction of perilla leaves. The decoction is made with 5 grams of dried perilla leaves and 200 grams of water. Chronic urticaria can be treated with sesame seeds. Regular consumption of sesame seeds improves the body’s constitution, strengthens the body and fortifies the skin so that the rash does not appear easily. (B) living conditioning method For cold urticaria, pay attention to the prevention of cold, especially in winter to wear more clothes, and eat less cold drinks in summer; for heat urticaria, less exercise in summer, not too hot water when bathing, prevent sun exposure, etc.
