Popis: Croton zehntneri Pax & K. Hoffm., Euphorbiaceae, or “canela-de-cunhé” is used in the Northeast Brazil to treat several diseases. Leaves and aerial parts of C. zehntneri are rich in volatile oil of high potential therapeutic. This study aimed to investigate volatile oil systemic toxicity after per oral treatment in rats. Volatile oil characterization (gas chromatography and mass spectrometry) showed 85.7% anethole and 4.8% estragole. Male Wistar rats (116–149 g) were treated with volatile oil (250 mg/kg p.o.) during ten weeks and evaluated for the following parameters: survival; food and water intake; body mass; absolute/relative organs weight; hemogram; plasma biochemical dosage; organs morphology. Volatile oil did not alter animal water and food consumption or the relative/absolute weight of most organs, but animals gained less weight. Volatile oil did not alter function biomarkers of pancreas, kidney, heart or liver, but increased plasma gamma-glutamyltranspeptidase (liver biomarker) and decreased uric acid (kidney biomarker). Although volatile oil had caused discrete morphological alterations in some organs, it did not induce architectural changes in these organs. In conclusion, the sub-acute per oral treatment with volatile oil no longer than ten weeks in rats offers small toxicity at doses below 250 mg/kg.
