The medicine can be used to treat hives. The main effect is to relieve the symptoms of the exterior and the interior, so it has a certain therapeutic effect on the damp-heat and wind-heat type of urticaria. However, for cold urticaria, or urticaria identified by Chinese medicine as wind-cold type, there is no therapeutic effect, and may even aggravate the symptoms of urticaria. Especially for some cold urticaria or pressure urticaria, the therapeutic effect of this drug is very limited. For wind-heat urticaria or damp-heat urticaria, treatment can generally be given orally twice a day, with about 10-20 pills taken orally each time. In addition to the treatment, you need to pay attention to avoid eating seafood, spicy and stimulating foods.
