Evaluation of Indian food spices for their beneficial hypoglycemic activity
Aqueous homogenates (10% w/v) of components of Indian dietary spices Allium cepa (onion), Allium sativum (garlic), Curcuma longa (turmeric, 1% w/v) and Zingiber officinale (ginger) when administered with 0.5ml/kg body weight in alloxan induced hyperglycemic male Wistar rats showed significant antihyperglycemic activity 30 minutes after glucose loading in rats under OGTT. The activity continued even after 2 hours. The fall of glycemia was in the range of 15–35% as compared to controls with minimum and maximum being with Curcuma longa and Allium cepa treated animals, respectively. Combinational (2, 3 and 4 plant extracts) studies did not show any significant additive effects.
