Botanical Description

Euphorbia pekinensis Rupr. (Euphorbiaceae) is a perennial herb 30-90 cm tall native to China, Korea, Japan, and the Russian Far East, with milky latex, erect stems, alternate lanceolate to oblong leaves, and the typical cyathium inflorescence with crescent-shaped yellow nectary glands. The cylindrical to conical taproot, fleshy and tan-brown externally, is collected in autumn or early spring, washed, and sun-dried. In TCM, Jing Da Ji is bitter and acrid in flavor, cold in nature, and toxic, entering the Lung, Spleen, and Kidney channels; it strongly drives out water accumulation, reduces severe edema and ascites, and dissipates clumps. It is normally processed with vinegar to attenuate toxicity before clinical administration.

Cultural & Historical Context

Traditional Chinese Uses

Jing Da Ji (euphorbia kansui or Euphorbia pekinensis) is a powerful draining herb used in Chinese medicine for severe fluid accumulation — including chest and abdominal effusions, generalized edema, and stubborn Phlegm masses — when gentler approaches have been insufficient. It is classified as toxic and is only used under professional supervision for short periods in critical conditions. It is typically processed with vinegar before internal use to reduce its toxicity, and is contraindicated with licorice root.
