The article describes experimental investigation of influence of laser irradiation on the drug activity of umbellate wintergreen and round-leaved wintergreen in the form of decoction and extract. The drug activity is estimated by counting the number of colonies grown on the nutrient medium with the addition of the studied plant preparation. It is shown that laser irradiation of pharmaceuticals significantly changes their activity, and the best results are obtained by irradiation of the umbellate wintergreen decoction.
