ABSTRACT. The aim of this study is to embed the active ingredients of the hydroalcoholic extract from the aristolochia (Aristolochia clematitis) into a new semisolid preparation and a viscoelastic methylcellulose based hydrogel in order to broaden the topical applicability of the palette's range. The methylcellulose based hydroalcoholic gel formulation, preparation and quality evaluation was realized by continuously measuring the product's physico-chemical parameters. The evaluated physico-chemical parameters: the swelling degree, the equilibrium swelling degree, the swelling rate and the swelling fraction, the swelling rate parameter, the swelling kinetics order, the speed constant.
