Nowadays there is an increasing interest to such an area of medicine as homeopathy. In this regard, the study of medicinal plants used in homeopathy is of great current interest. The search for new species that can be used in homeopathy is still continuing. The aim of our study was to identify Siberian poisonous plants, which could be used in homeopathy, basing on the author's own research and literature data. The conducted research allowed us to draw a list of poisonous plants of Siberia, used in homeopathy. The list includes 23 species, listed in Latin, with the indication of homeopathic raw materials, area of medicine and the diseases which can be treated applying this species in homeopathy. The author conducted field studies of medicinal plants, including poisonous plants, in Siberia, the Kuznetsk Alatau, in particular. To select the material, the technique of regular laying the key sites and a network of expedition routes were used. In most cases, namely in 17 species, the whole plant can be used as the source of raw material. The underground part alone is used in two species. The aboveground part alone is also used in two species. Most poisonous plants (14 species) are not listed in scientific medicine and are used in traditional medicine and homeopathy. 9 species of poisonous Siberian plants are used in scientific and traditional medicine and homeopathy. Poisonous plants used in homeopathy are applied in treating a variety of diseases, both of mental and somatic nature. The author hopes to continue research in this area to expand the list of species used in homeopathy to help people cope with various diseases which are not always successfully treated by the methods used in conventional medicine.
