The article presents the results of a morphological and anatomical study of the aboveground part of the common self-heal (Prunella vulgaris L.) collected during the mass flowering period in the Bustanlik district of the Tashkent region. Despite the fact that the common self-heal is not a pharmacopoeia plant and is not used in official medicine, thanks to the healing chemicals that make up its composition, it has some medicinal properties. Data on the morphology and main diagnostic microscopic features of the herb Prunella vulgaris L., which are of decisive importance for establishing the authenticity of medicinal plant raw materials, were obtained. The purpose of the study: to determine the morphological and anatomical features of the grass of the common self-heal. Materials and methods. The plant material was collected during the period of mass flowering in the Tashkent region. Microscopic signs were studied according to the methods of the State Pharmacopoeia of the Russian Federation of the XIII edition using a Micromed-1 light microscope, photos were edited in the program Paint. NET.3.5.11. Results. Morphological analysis of the whole leaves and stem of the common self-heal showed compliance with the literature data. The leaves are whole, simple, lanceolate with a wedge-shaped base and a blunt tip, the stem is tetrahedral, reddish, whitish-woolly at the tip. The main diagnostic microscopic signs of the herb can be indicated as follows: cone-shaped unicellular trichomas, simple multicellular trichomas, trichomas with a multicellular pedicle and funnel-shaped trichomes and with a unicellular pedicle and spherical head, radial-type essential oil glands with 6-8 excretory cells. Conclusion. During the morphological and anatomical study of the grass, diagnostically significant microscopic signs of raw materials were revealed. The results of experimental studies supplement the data of the scientific literature and can be used to confirm and establish the authenticity, identification and standardization of the aboveground part of this sample.
