Extracts of 32 medicinal plants used popularly for their presumed diuretic and/or antihypertensive properties were tested for diuretic effects in conscious unrestrained rats. Extracts were made using aqueous ethanol (50:50, v/v) at 4-10 degrees C. When given orally at a dose of 40 ml/kg, a majority of the ethanol-free extracts produced a more pronounced diuresis than would be expected from the potassium concentration of the extracts. The most significant diuretic effect was observed with Hedychium coronarium sheath and leaf-blade extracts.
