Does Aerua lanata have diuretic properties?

We have compared the diuretic activity of 200 ml of sucrose flavoured aqueous extract of the herb Aerua lanata with that of 200 ml sucrose flavoured weak infusion of tea leaves, and 200 ml of water, in 14 healthy volunteers under standardized conditions. Each volunteer acted as his or her own control in the three protocols, and chemical, physical and statistical analyses were performed "blind" by coding all urine and blood samples collected. A. lanata extract did not significantly increase urine flow, sodium excretion, potassium excretion, or urine and plasma osmolality as compared to an infusion of tea or plain water.
