Locals around the world have been used botanical extracts to reduce the effects of this deadly disease to improve the quality of life of the patients. Objectives: To evaluate the effects of crude extracts of the ethnobotanical species K. daigremontiana on a hyperglycemia rat model to support its antidiabetic use in traditional medicine. Materials and Methods: Crude leaves extract were daily administered per os to Wistar rats for six months. Hyperglycemic induction model was rich-sucrose diets. Six animals per group were used: i) standard diet, ii) sucrose-rich diet, iii) sucrose-rich diet + extract (1 ml), iv) sucrose-rich diet + extract (2 ml) and v) standard diet + extract (2 ml). All animals were sacrificed and the liver prepared for histopathological analysis. Powdered leaves were functionally characterized and analyzed by Fourier Transform Infrared (FTIR) spectroscopy. Results: Treatment with 2 ml of the crude extract caused the least tissue damage, compared to the control. A high antioxidant activity (DPPH: 111.14 ¿M Trolox equivalents g-1 dry weight (DW); ABTS: 223.90 ¿M Trolox equivalents g-1 DW) was observed. A content of 0.54 mg ascorbic acid g-1 DW, total phenol content of 17.45 mg gallic acid g-1 DW and flavonoid content of 2.3 mg equivalent quercetin g-1 DW were determined. No conclusive evidence on the molecules present in the extract was obtained by FTIR spectroscopy. Conclusion: The use of dosages of 2 ml of crude extract of Kalanchoe daigremontiana reduces liver damage under high sucrose conditions.
