Introduction: Polyherbal formulations used for management of diabetes in Kenya lack studies to determine their efficacy or safety. Objective: To evaluate the efficacy and safety of two anti-diabetic polyherbal formulations (LUC and MUI). Method: Herbs were collected, dried and formulated. Formulations were evaluated using grouped alloxan induced wistar rats. Effects were compared to conventional drugs; pioglitazone (3mg/kg bw), glibenclamide (100 mg/kg bw), metformin (100 mg/kg bw) and normal control group. Each group received an individual drug/water once daily orally for fourteen days. Blood glucose levels were evaluated every seven days using a glucometer. Liver function tests and lipid profile were measured on day 14. The data was expressed in mean ± SEM. Analysis was by ANOVA and post hoc multicomparison Turkey test (p < 0.05). Results: No mortalities reported. Both herbal preparations had hypoglycemic effects. LUC was more potent. MUI increased all lipid levels. LUC caused intestinal gas distention on gross examination. Conclusion: The herbal formulations were hypoglycemic at the tested doses.
