Botanical Description

Stephania tetrandra (Fang Ji, fourstamen stephania) is a perennial herbaceous to slightly woody climber in the Menispermaceae family, twining up to several meters through surrounding vegetation. The slender, pale green to grayish stems arise from a stout tuberous root, the medicinal material, which is cylindrical to irregularly shaped, often curved, 5 to 10 centimeters long and 1 to 5 centimeters thick, externally pale grayish-brown with deep transverse furrows and shallow longitudinal grooves, internally pale yellowish-white with radial striations on cross section. The alternate leaves are long-petioled, peltate, and broadly ovate to triangular-ovate, 4 to 7 centimeters across, with entire to slightly undulate margins and a pale grayish-green underside. Inconspicuous dioecious greenish-yellow flowers are borne in small axillary umbel-like cymes in summer. The fruits are small, fleshy, reddish drupes containing curved, horseshoe-shaped seeds. Native to central, eastern, and southern China and Taiwan, growing on hillsides, in scrub, and at woodland margins.

Cultural & Historical Context

Traditional Chinese Uses

Fang Ji (stephania root) is a bitter, cold herb particularly effective at clearing Damp-Heat from the lower body and draining excess water. It relieves joint swelling, pain, and heaviness caused by Wind-Damp or Damp-Heat obstruction, and its strong diuretic action addresses edema, difficult urination, and swelling of the lower limbs. Its cold nature makes it best suited for heat-type bi obstruction, distinguishing it from warming herbs used for cold-type joint pain.
