Every day around the world, children and adults suffer from burn injuries. Burn injury is one of the global health problems due to its high prevalence and mortality. The skin is the largest multifunctional human organ. The area of the entire skin is on average 1.7-1.9 square meters. The skin has a wide variety of functions from protective to energy-saving and tactile. Burns have a long history, but new methods of study are needed, this is due to the increase in the frequency of burns in everyday life, production, as well as the complexity of the pathogenesis and treatment of burn disease. Pathological changes that occur in the body of burned animals lead to the fact that in the first hours with extensive burn injury, circulatory disorders occur in parenchymal organs, especially in the liver, lungs and adrenal glands. In the future, with severe intoxication, severe dystrophic processes occur in the muscles of the heart and other internal organs. Recently, the main areas of research into the pathogenesis of inflammation have become immunological, at the morphological level it has not been sufficiently studied. The article shows the morphological features of the study in thermal burns of the skin of rats during treatment with a different mechanism of action. Rats in the amount of 15 pieces were divided into 3 groups: the first control group with a burn without treatment, the second group with a thermal burn, to which levomekol gel was applied to the burn area, the third group was treated with powder from the medicinal plant yarrow Achillea millefolium L. On the 3rd, 7th, 14th, and 21st days, the rats were taken out of the experiment, after which the skin pieces were fixed in 10% formalin for further histological examination.
