Studying of topical-product-induced irritation properties of pharmaceutical forms elecampane (Inula helenium) (herbal infusion, tincture, liquid and dry extracts) on skin integuments and conjunctiva of experimental animals (Guinea pigs (Cavia porcellus), rabbits (Oryctolagus), sheep and piglets). Research results showed that the preparative forms of elecampane had poorly expressed irritating properties after application on the skin of animals, as well as weak irritating action with the exception of the native forms of tincture and liquid extract of eye conjunctiva, that proved their total low toxic effect. Topical-product-induced irritation effect of herbal infusion (1:10), tincture and liquid extract in constitution (40 % concentration) and suspension of dry extract in strength of 10%, 15%, and 20% after the single application on skin could be referred to the I class – absence of irritating action. Topical-product-induced irritation effect of herbal infusion and liquid extract in native form (70% concentration) could be referred to the II class – light irritating action. Irritating activity of herbal infusion of eye conjunctiva was evaluated as light, as it was insignificant and short. Irritating action of suspended matter of dry extract in strength of 10%, 15%, and 20% was estimated as a limited one, which disappeared in 24 hours. Irritating action of tincture and liquid extract in constitution (40 % concentration) was evaluated as a high-grade one, which did not disappear in 24 hours. Irritating action of tincture and liquid extract in native form (70 % concentration) was evaluated as a pronounced one, which did not disappear for than 24 hours
