Chinese medicinal compound stops formation of cysts in polycystic kidney disease in lab
... cysts, the kidney begins to swell, and the person moves to either dialysis or transplant in order to survive. That means a treatment that slows down the development of cysts does not have to stop their production completely to be effective, says Dr. Crews.
