Any plant phylogenesis is a long-term historical complex of plant species, including elements of different ages, different origins and differing from other floristic complexes in its systematic composition. This complex is a dynamic and unstable phenomenon that changes over time. Its individual elements disperse, or, conversely, remain within the boundaries of their range, de-pending on changes in external ecological and geographical factors. Therefore, when study-ing any floristic composition, it is necessary, first of all, to systematize the plant world. The distribution of species between systematic categories of the highest rank characteristic of each flora. Issues related to the characteristics of the growth, procurement and protection of plant medicinal raw materials are one of the leading links in ongoing activities for the ration-al use of natural resources throughout the world. Medicinal pharmacopoeia plants growing in various regions of Russia are a valuable source of biologically active substances used in med-icine and pharmaceuticals. The study of medicinal plants is important for optimizing the drug production process, as well as for the conservation of biodiversity and sustainable use of natural resources. Methods for studying medicinal pharmacopeial plants include a botanical description of plants, analysis of the chemical composition and pharmacological properties of raw materials, the study of factors affecting the quality and quantity of biologically active substances, as well as the development of methods for growing and collecting plants. Much attention is also paid to the issues of sustainable use of medicinal plants and their conservation in natural ecosystems. The study of medicinal pharmacopoeia plants growing in various regions of Russia, including the Republic of Tatarstan, allows us to determine the optimal conditions for their cultivation, evaluate the quality and effectiveness of the raw materials used, and also develop new drugs based on natural components. The more work there is related to the study of the growth of medicinal plants, the more it will contribute to improving medical practice, enriching the range of medicines and providing access to effective and safe medicines.
