Chief herb in Ji Chuan Jian?

• A. Shu Di Huang
• B. He Shou Wu
• C. Rou Cong Rong
• D. Dang Gui

Answer: (C)

In Ji Chuan Jian, the main issue is constipation caused by kidney deficiency with resulting dryness. The herb that provides the core action is one that both nourishes the kidney and directly lubricates the intestines, addressing the underlying deficiency and the stool dryness at the same time. Rou Cong Rong fits this role perfectly: it tonifies the kidney and essence while acting as a strong moist laxative to soften and ease the bowels. That combination is what drives the formula’s therapeutic effect for this pattern.

The other herbs contribute supportive functions—nourishing yin, blood, and overall foundation—but they do not supply the primary lubricating laxative action the formula relies on.
