The search for new sources of medicinal plant raw materials for the production of drugs is one of the urgent tasks of modern pharmacy. The expansion of the range of medicinal plant raw materials is possible, first of all, due to the types systematically close to the official ones. In medical practice, wild strawberry leaves are used. Wild strawberry leaves are used in medicine as a diuretic, anti-inflammatory, antispasmodic, choleretic, hypoglycemic, antipyretic, hypolipidemic, antimicrobial and appetite-enhancing agent. Earlier studies of strawberry leaves have shown that they have a rich chemical composition and are widely cultivated in Russia, being an affordable source for mass procurement of raw materials, and are not used in scientific medicine. At the same time, in folk medicine, strawberry garden leaves are used similarly, and sometimes instead of wild strawberries. The proximity of the composition of biologically active substances of wild strawberries and garden strawberries. To expand the modern nomenclature of medicines, studies on the comparative study of the toxicity and pharmacological activity of infusions and extraction forms from medicinal plant raw materials of strawberry leaves are relevant. In this regard, the study of the toxicity, diuretic and anti-inflammatory activity of the infusion of garden strawberry leaves and the extract of dry strawberry leaves is of practical interest for the formation of a scientific justification for their use in medical practice.
