The effect of ethanol extract of whole plant of Cynoglossum zeylanicum on Oral Glucose Tolerance was determined. Ethanol extract of Cynoglossum zeylanicum were evaluated for Oral Glucose Tolerance Test (OGTT) in normal and alloxan induced diabetic rats. Oral administration of ethanol extract at doses of 100 &150mg/kg body weight shows that the extract promote glucose uptake. These results suggest that the ethanol extract of Cynoglossum zeylanicum whole plant will be useful in the treatment of impaired oral glucose tolerance.

In the present study, Melastoma malabathricum leaf was extracted with ethanol and evaluated for anti-inflammatory activity in rats using a carrageenan induced paw edema method. Ethanol extract exhibits potent anti-inflammatory activity at 500mg/kg at 3hr after administration. The study was compared with standard drug indomethacin (10mg/kg). Observed pharmacological activity in the present study provides scientific validation of ethnomedicinal uses of this plant in treating acute inflammation.
