The present work describes the nature of a herbal medicine in liquid phase, prepared by a native of Tinsukia district of Assam. Kidney stone of moderately big size (13.9 x 9.4 mm) of a particular female patient is completely dissolved after she took the herbal medicine 10 ml thrice daily for ten days. X-ray photographs and ultrasound record taken before and after taking the medicine indicates beyond any doubt that the particular uric acid type stone is absent. Earlier the patient was treated with various procedures like, lithrotripsy (thrice), with and without introduction of a ureteral stent, but without any effect. An X-ray and ultrasound photographs decisively prove the positive effect of the native medicine. In the present work we describe the scientific basis of the miraculous effect based on the available literature in recent times.
