Clinical and experimental studies on the treatment of senile constipation with shenshen wan

From August 1988 through February 1991, we have successfully treated 400 cases of senile constipation with self-made Shenshen Wan with a total effective rate of 98%. A group of patients taking Maren Wan served as controls. Clinical practice has proved that Shenshen Wan can not only relax the bowels, but also improve renal function. Furthermore, no side effects whatever were observed after a prolonged administration of the pills.
