A parallel study on the effects in treatment of impotence by tonifying the kidney with and that without improving blood circulation.

141 cases of functional impotence of the kidney-deficiency type were treated by tonifying the kidney. On them, 103 cases at the same time were treated by improving blood circulation and the other 38 cases by the former only. As a result the total effective rate and the markedly effective rate in the former were 84.46% and 46.60% respectively; but in the latter, 60.55% and 13.15%. A significant difference was found in Ridit analysis (P < 0.05), indicating that method of tonifying the kidney with improving blood circulation is much better than by simply tonifying the kidney alone.
