Anti-hyperglycemic effect of some edible plants

Abstract

The anti-hyperglycemic effect of 12 edible plants was studied on 27 healthy rabbits, submitted weekly to subcutaneous glucose tolerance tests after gastric administration of water, tolbutamide or a traditional preparation of the plant. Tolbutamide, Cucurbita ficifolia, Phaseolus vulgaris, Opuntia streptacantha, Spinacea oleracea, Cucumis sativus and Cuminum cyminum decrease significantly the area under the glucose tolerance curve and the hyperglycemic peak. Brassica oleracea var. botrytis, Allium cepa and Allium sativum only decrease the hyperglycemic peak. The glycemic decreases caused by Psidium guajava, Brassica oleracea and Lactuca sativa var. romana were not significant (P > .05). The integration of a menu that includes the edible plants with hypoglycemic activity for the control and prevention of diabetes mellitus may be possible and recommendable.
