Background & objectives: Painful diabetic neuropathy is a common complication of diabetes and can severely limit patients' daily functions. The aim of this pilot study was to evaluate the safety and effect of using a polyherbal formulation in reducing the symptoms of diabetic neuropathic pain in comparison with placebo among patients with type 2 diabetes. Methods: A total of 50 (M:F = 33:17) consecutive type 2 diabetes patients with painful diabetic neuropathy were enrolled in this study. All these patients had either two or more symptoms of diabetic neuropathy such as pain, burning and pricking sensations and numbness in their feet. They were randomly assigned to two groups: group 1 (n = 26) patients were treated with polyherbal formulation cream and group 2 (n = 24) patients were administered placebo. The patients were followed up for six months. Changes in the symptoms of painful diabetic neuropathy of each patient were recorded at baseline, third and sixth month using the Diabetic Neuropathic Score. Results: The mean age of the patients, duration of diabetes and glycated haemoglobin (HbA 1c ) were similar in both groups at baseline. During follow up visits, there was a decrease in the HbA 1c levels in the study and control groups. The symptoms of painful diabetic neuropathy were also similar in both groups at baseline. A significant decrease in symptoms of neuropathic pain was observed among the group of patients treated with polyherbal formulation cream (76.9 per cent) compared to the placebo-treated group (12.5 per cent) (P<0.001), at the end of the final follow up. Interpretation & conclusions: In this pilot study polyherbal formulation cream was found to be effective as well as safe to treat painful diabetic neuropathy. However, its long term use needs to be evaluated for any further effectiveness and side effects.
