INTRODUCTION: Solanum torvum Sw., commonly known in Cuban eastern zone as prendejera, belongs to Solanaceae family and is very used due to its traditional medicinal properties as antimicrobial, antiarthritic and anti-inflammatory. OBJECTIVE: to assess the toxicity level by repeated doses for 28 days of leaves and stems decoction of S. torvum by oral route in rats. METHODS: a toxicity trial was made in repeated doses by limit test method for 28 days in a decoction of S. torvum in a 1 000 mg/kg dose, administered by oral route to Sprague Dawley rats. Hematology, blood Biochemistry examinations and anatomical and pathological and histopathological corresponding analyses were made. RESULTS: there were not toxicity signs in animals and no affectations in body weight. The results of histopathological analysis demonstrated the lack of organic damages provoked by the assessed decoction and corroborated the above results. CONCLUSIONS: in trial conditions, the decoction of leaves and stems of S. torvum there were not toxic reactions attributable to essayed substance.

INTRODUCTION: Azadirachta indica A. Juss, known as Neem tree, has various applications in agriculture, veterinary medicine and health care, thus it is a relevant vegetable species due to its antimicrobial, antiparasitic and immunostimulating properties. OBJECTIVE: to detect any signal of toxicity after daily oral administration of decoction for 28 days. METHODS: a repeated dose toxicity assay using a A. indica decoction at a dose of 1000 mg/kg, orally administered to Sprague Dawley rats for 28 days. Clinical signs and body weight of the study animals were evaluated together with hamatological, blood chemistry, anatomopathological and histopathological analyses. RESULTS: this decoction brought about neither significant change in the body weight nor clinical signs indicating toxicity. There were not altered hematological and biochemical indicators that may be attributed to the substance under testing. The anatomopathological results did not show any alteration upon systems, organs and tissues. CONCLUSIONS: the study did not reveal toxic effects in the animal model that might be connected with the repeated oral administration of A. indica decoction under the study conditions.
