“…However others (e.g. bittergourd, jamun and fenugreek) have been documented for their hypoglycaemic effects (Basch, Ulbricht, Kuo, Szapary, & Smith, 2003;Bogacheva, Ulezlo, & Kogan, 1976;Eidi, Eidi, & Sokhteh, 2007;Krawinkel & Keding, 2006;Warier, 1995). But some more research needs to be done on the hypoglycaemic activity of these extracts as their mechanisms of action, whether it is via stimulation of insulin secretion or altered glucose metabolism, are still unclear (Krawinkel & Keding, 2006;Plant Resources of Tropical Africa Database, 2006).…”
