The extract showed significant antipyretic effect on yeast-induced fever in rats at 600 mg/kg that persisted up to 3 h of the study. The extract at the doses 400 and 600 mg/kg significantly reduced the numbers of writhings induced by intraperitoneal injection of acetic acid in mice. The most important carbohydrate is glucose, which can be broken down via glycolysis, enter into the Kreb's cycle and oxidative phosphorylation to generate ATP.
