Xu Chang Qing徐长卿
Cynanchi Paniculati Radix et Rhizoma · Paniculate Swallowwort Root
Overview
Root and rhizome of paniculate swallowwort, acrid and warm, with a straightforward reputation as an analgesic: wind-damp joint pain, aching low back and knees, toothache, epigastric pain and pain after injury. Its second use is dermatological — itching, eczema and urticaria, taken internally and applied as a wash. Its active constituent is volatile, so it is added late in the decoction.

Cautions
Warm and dispersing: it does not suit weak, yin-deficient patients with heat signs. Add it late and decoct it briefly — long boiling drives off the volatile constituent that carries the effect. Snakebite is a medical emergency; herbs are no replacement for antivenom and hospital care.
