Introduction: Effects of antimutagenic and non-genotoxic agents of tannins from Pinus caribaea Morelet, as well as its influence in improvement of quality life of patients have been demonstrated. Our aim was to assess chronic oral toxicity of tannin powder obtained from bark of P. caribaea in Cenp:SPRD rats. Material and Methods: Rats were randomly distributed into four experimental groups: Control, Low (1 mg/kg), Median (2 mg/kg) and High Dose (5 mg/kg). Administration was made daily along the six months of the study. Rats were inspected daily for clinical signs. Body weight and food and water consumption were weekly measured. Hematological and biochemical analysis were performed at the beginning, three months and at the end of experimentation. Gross necropsy and histological examination of tissues were performed on animals at the end of the assay. Results: During the study a female in Low Dose group died, the remainder finished the study in a good state. Clinical signs described were distributed by all groups and were considered not to have relation with the tested substance. Body weight curve was similar for all groups. Water consumption increased in animals treated with the higher dose, but the food consumption was normal. Clinical laboratory parameters had differences, although they were within normal ranks reported for the species. There were no macroscopic or microscopic lesions related with the tested substance. Conclusions: The tannin powder obtained from bark of P. caribaea appears to be safe under the experimental conditions established.
