Abstract

Background: The patho-physiological cross-talk between diabetes and obesity is well established. However, the choices of drugs suitable for combined treatment of diabetes and obesity are limited. Integration of complementary and alternative medicines (CAMs), like Ayurveda, with modern medicine would be a promising strategy to fill this gap. The diagnostic principles of Ayurveda define obesity as one of the predisposing factors of Madhumeha (correlated as diabetes) and recommends specific formulations for managing obese-diabetes. Lodhrasavam is one such poly-herbal formulation prescribed for obese-diabetic patients.

Objectives: The present study is an attempt to demonstrate the possible modes of action of Lodhrasavam, built on the hypothesis that the formulation can exert both anti-diabetic and anti-obesity actions.

Materials and methods: Lodhrasavam, following simulated gastro-intestinal digestion, was monitored for inhibition of α-amylase, α-glucosidase (key digestive enzyme targets of anti-diabetic drugs) and adipogenesis using standard in vitro model systems.

Results: Lodhrasavam digest inhibited α-amylase (90%) and α-glucosidase (78%) activity as well as reduced the differentiation of 3T3-L1 fibroblasts to adipocytes. Upon fractionation, the enzyme inhibitory activity and anti-adipogenic activity of the digest were found distributed in different solvent fractions. This partly indicates a potential pharmacological networking of chemically and functionally diverse bioactive molecules in Lodhrasavam.

Conclusion: The study provides a possible mode of action and an experimental support for the Ayurvedic use of Lodhrasavam for managing obese-diabetes. Generating scientific evidences and understanding the modes of action, in contemporary scientific language, would essentially help in expanding global acceptance of potentials of CAMs in the management of life style disorders.
