Transforming medicinal plants into industrializable and marketable products involves meeting numerous regulatory requirements regarding the quality, safety, efficacy and stability of the proposed formulation. In this context, the product Curcuvet (antiseptic and healing solution obtained from the hydroalcoholic extract of C. longa) needs to demonstrate its safety before being legally used in veterinary clinical practice. Therefore, the present work aimed to evaluate in vivo the dermal and ophthalmic toxic potentialities of the product. To achieve this, three in vivo investigations were carried out: acute dermal toxicity, primary dermal irritancy and ophthalmic irritancy according to the standards described by the Organization for Economic Cooperation and Development (OECD) No. 434, 404 and 405, respectively. The Curcuvet product in all tests was administered as a single dose, superficially on both skin (Sprague Dawley rat and F1 rabbits) and ocular mucosa (New Zealand albino rabbits). The Curcuvet product was not irritating to the skin of rats and rabbits, but not to the ocular structures, which were severely damaged, reaching an irritancy index of 110. It is concluded that the Curcuvet formulation, administered in single dose, was not a dermal irritant and a severe ophthalmic irritant.
