Diabetes mellitus and its related complications are of the major chronic diseases affecting millions of people worldwide. Recently, there has been an increasing need in the use of medicinal plants to ameliorate and control DM. This is attributed to that most of the pharmaceutical products in the market induce severe complications following long term use. In response, many Eastern-Mediterranean patients use traditional herbs to treat DM. The purpose of using these herbs is the economical value and the fewer side effects of these herbs, compared to the marketed synthetic drugs. Our current work aims at standardization and evaluation of the antidiabetic and antinociceptive potential of two selected Eastern-Mediterranean plants. Bio-guided and RP-HPLC fractionation combined with acute (6 hrs) and subacute (8 days) administration of extracts and their most active fractions were assessed in alloxan diabetic mice (n=7/group). Likewise, the thermal antinociceptive effects were investigated chronically (8 weeks) to access the herbal plants ameliorating effect on alloxan-induced diabetic neuropathy. Our results demonstrated significant experimental anti-diabetic and antinociceptive effectiveness. It is strongly recommended to consider the Eastern-Mediterranean medicinal plants to the amelioration of chronic diseases, such as DM and its related complications.
