Abstract The genus Veronica L. of the family Plantaginaceae Juss. comprises approximately 500 species distributed worldwide, particularly across the Northern Hemisphere – Europe, America, Asia, as well as in parts of Africa and Australia. Plants of the genus Veronica and their extracts, infusions, and decoctions are widely used in traditional medicine to treat cardiovascular diseases, gastrointestinal disorders, respiratory conditions, coughs, influenza, bronchitis, hoarseness, gout, rheumatoid pain, kidney and gallbladder disorders, and metabolic impairments. The fresh herb is applied in the treatment of wounds, skin eruptions, eczema, ulcers, burns, snakebites, and carbuncles. Water- or oil-based extracts are also used to treat bacterial- or fungal-induced skin diseases.
Currently, more than 1,100 medicinal plants are registered in the Mongolian flora. The chemical composition and certain biological and pharmacological activities of over 10 percent of these species have been scientifically investigated. In Mongolia, 27 species of the genus Veronica are officially recorded. However, research results remain insufficient. Generally, Veronica species, considered grassland plants in Mongolia, are tolerant of harsh climates and adaptable to dry conditions. Therefore, studying their chemical composition and specific characteristics, identifying biologically active components, and evaluating their biological and pharmacological activities is crucial. Such research not only validates their traditional uses but also supports the development of scientifically based new products for the prevention and treatment of ailments in living organisms.
