Antidiabetics Interactions with Herbs: A Compressive Review.

Diabetes mellitus is a chronic illness with a variety of causes and pathophysiology. For the management of diabetes, various synthetic antidiabetic drugs are available. Still, people prefer complementary and alternative therapies as well as traditional herbal home remedies because they are perceived to be free of side effects and generally recognized as safe due to their natural origin. Hence, worldwide, the majority of the population is consuming herbs and/or herbal products in their daily routine. It has been observed that individuals with diabetes also consume herbs/herbal products either with or without medical supervision. This co-consumption of antidiabetic medications and herb/herbal products may result in herb-drug interactions, which might be potentially beneficial or harmful or, in some cases, even fatal. Most of the times, these interactions remain unnoticed or undiagnosed due to lack of knowledge and awareness about them. In this review, the authors have summarized some important aspects related to the herb-drug interaction (HDI), which include methods for prediction and mechanism of HDI (pharmacokinetic and pharmacodynamic) and also the clinical and experimental literature on herb-drug interactions (HDI) in the treatment of diabetes. Authors have attempted to categorize the interactions between oral hypoglycemic agents and various herbs as beneficial or harmful based on the results reported in the original research work.
