From these findings, the water turned out to ta Johar leaf decoction dose of 2.5, 5.0, and 10.0 g / kg bb can reduce LDDK (The area under the curve) blood glucose level of negative control, the group of normal mice given a glucose load (DMTTI - UTGO = no insulin-dependent diabetes mellitus. oral glucose tolerance test). In the group of normal mice are not given a glucose load (DMTTI), leaves boiled water Johar dose 10.0 g / kg bb can reduce blood glucose levels LDDK of 15:06% against a negative control. , 1993. Department of Pharmacy, FMIPA UI. Has conducted research hepatoprotective effect of leaf infusion Johar on white rats given carbon tetrachloride.
