The disease can be caused by external factors (temperature, mechanical, chemical) or internal (diseases of internal organs, disorders of the nervous system). [1, 2]. Allergies can be caused by toxins, bacteria, and undigested food. In the diagnosis of the disease, anamnestic data, dermography and various skin allergological tests are used. There are acute (up to 6 weeks) and chronic (more than 6 weeks) urticaria. The latter is characterized by daily or frequent symptoms (blistering, itching, angioedema for 6 weeks or more [3, 4]. During life, 0.5-1% of the entire population of people suffers from chronic urticaria. At the same time, if acute urticaria is usually associated with the action of exogenous factors and allergens (food, medicines, insect bites, etc).
