Clinical Studies:

Medical management of urinary calculus disease is a challange for modern science. In the present trial Ayurvedic drug “Herbmed,” which is made up of varuna (Crataeva nurvala) and banana stem (Musa paradisiaca) was assessed to see reduction and/or expulsion of urinary calculi and also to assess the role of these drugs to reduce pain during expulsion.

In this prospective randomized, double-blind, placebo control trial, total 77 patients with calculi more than 5 mm were included. All patients were evaluated either by X-ray KUB or USG KUB for 3 months. 

All patients were divided into two groups: group A included patients with calculi 5-10 mm and group B with calculi > 10 mm with either active treatment or placebo in both the groups. All patients were asked to keep a record of number of pain episodes, while severity of pain was measured on a visual analogue scale.

In group A, there was 33.04% reduction in the size of calculi in the active arm while there was a 5.13% increase in the same group in the placebo arm. In the other group B, there was an 11.25% reduction in the active arm and a 1.41% reduction in the same group with placebo. 

The preliminary experience suggests that the Ayurvedic formulation “varuna and banana stem” has promise for the management of upper urinary-tract calculi, especially renal calculi. It helps to dissolve renal calculi and facilitate their passage. In addition, it also helps in reduction of pain due to renal/ureteric calculus disease.
