Constipation that stems from deficiency with a need for warmth is best treated by a herb that tonifies yang and also moistens the intestines to ease stool passage. Rou Cong Rong does exactly that: it tonifies kidney yang, which provides the warmth and energetic drive to fluids, and it also moistens and lubricates the bowels, helping stools move more smoothly. In many cases of elderly or deficient patients with dry, hard stools, this gentle, warming support can unblock the bowels without harsh purge. It also has a blood-nourishing aspect that supports overall circulation and vitality, aligning with its ability to improve the body’s ability to move and nourish blood. By contrast, the other herbs here focus more narrowly (nourishing or activating blood, or exerting purgative heat), and do not address the combination of yang deficiency and bowel dryness as effectively.
