Parasitic infections are one of the most acute problems of the modern society as this group of diseases is met in all countries of the world. According to the World Health Organization around 1.2 billion people are infected with diverse parasitic infections each year. Helminthiases of digestive system, primarily nematodosis, constitute a group of special risk, since a particularly sensitive audience for them are children of younger and middle age. Phytotherapy, which is based on the centuries-old experience of folk medicine, promises to be a solution to this problem, enabling to create effective complex medicines for nematodosis prevention and treatment. Thus, the herbal mixture was prepared on the basis of the offered composition of medicinal plant raw material. The research of antimicrobial activity of the studied herbal mixture was conducted in vitro by the method of diffusion into agar at the Biotechnology Department of the National Pharmaceutical University under the direction of Doctor of Pharmaceutical Sciences, prof. Strelets O.P. The obtained results of the carried out research of the antimicrobial properties of the herbal mixture samples allowed examining the level of antimicrobial activity. The further research of the investigated herbal mixture and the offered phytocomposition is promising for creation of new effective medicines with the complex action including anthelminthic (specific to nematodes), antiparasitic, anti-inflammatory, antibacterial, antiseptic, hepatoprotective, nephroprotective, laxative, antiallergic, antispasmodic, analgesic, sedative activities
