Overview

Shu Jing Huo Xue Tang — the “Relax the Channels and Invigorate the Blood Decoction” — is from the Ming-dynasty Wan Bing Hui Chun. It addresses chronic Wind-Damp-Cold obstruction of the channels combined with Blood stasis — the picture of long-standing joint or nerve pain that has both stagnation and accumulation features, where the pain is fixed and deep but also worse with damp weather.

The formula combines Wind-Damp herbs (Qiang Huo, Du Huo, Wei Ling Xian) with Blood-moving herbs (Tao Ren, Dang Gui, Chuan Xiong, Niu Xi, Bai Shao), Damp-resolving herbs (Cang Zhu, Fu Ling) and a small amount of Sheng Di, plus Gan Cao and Sheng Jiang.

I prescribe Shu Jing Huo Xue Tang as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan.
