[Propolis extract. I. Acute toxicity and determination of acute primary cutaneous irritation index].

Abstract

In first part, the aim of this work is to study the orally subacute toxicity of a propolis extract on conscious mice. LD50 is more than 7.34 g/kg propolis extract: this product is not toxic. In second part, cutaneous primary irritation of several products: excipients and propolis extract alone or in ointments, is evaluated in the rabbit. The cutaneous reactions after reiterated applications for 14 days are observed. The index of cutaneous primary irritation is calculated by evaluation of the erythematous and oedematous lesions. The propolis extract is non irritant.
