Abstract
Prosopis fracta (Leguminosae) has been used in Jordanian folk medicine as a hypoglycemic and hypotensive agent. The hypoglycemic activity of an aqueous solution of the lyophylized root extract of Prosopis fracta was tested in normoglycemic and streptozocin-induced hyperglycemic rats. Results indicate that the root extract caused significant reductions in blood glucose concentration when given orally.
