With the changing environment and unsafe diet, there are more and more patients with urticaria. 90% of people will have urticaria 1-2 times in their lifetime, which is commonly known as “wind clusters”, and will naturally return to normal, but there are some patients who have acute attacks that become chronic, and once chronic is formed, it is difficult to cure. Many people will rely on anti-allergy drugs to control the symptoms, eat a grain of cetirizine or Epinephrine can control 1-2 days, or even a week, but can not stop the drug, recently some experts proposed to double the dosage, gradually reduce the amount of treatment, but still can not stop the drug, a patient with urticaria for more than 10 years told me that due to long-term anti-allergy drugs, resulting in memory loss, more than 30 years of age, forgetting things very quickly, the memory is significantly reduced. It is possible to have a significant memory loss because most anti-allergy drugs have a central nervous system suppressing effect, and dizziness, desire to sleep, and dry mouth are the most common side effects. That is why most patients come to seek treatment in TCM. Most patients can be cured by changing their constitution through TCM evidence-based treatment.
