Abstract: The present invention relates to the area of pharmacology; its objective is to solve the technical problem of inflammation, pain, pruritus and local hyperthermia in human beings and animal species. The composition and the subcompositions thereof are obtained from plants of the family Cactaceae, the main methodological steps being a set of processes: production, purification, physicochemical quantification, biotherapeutic evaluation, biopharmaceutical formulation and molecular identification. From the molecular identification a set of molecules is recognized, comprising carbohydrates and an aromatic amine, the general formulae of which are:C.sub.5 H.sub.10 O.sub.5 (RIBOSE),C.sub.6 H.sub.12 O.sub.5 (FUCOSE),C.sub.6 H.sub.12 O.sub.6 (GALACTOSE; MANNOSE; GLUCOSE),C.sub.8 H.sub.11 O.sub.2 N (1-HYDROXY-1-(4-HYDROXYPHENYL)-2-AMINOETHANE),C.sub.10 H.sub.18 O.sub.9 (RIBOFURANOSYLRIBOSE).
