Description

Huai Hua San (Sophora Japonica Flower Powder), from the Ben Shi Fang, is used to cool the intestines; stop bleeding; disperse wind; regulate Qi.

Presentation: intestinal wind from wind-heat or damp-heat; fresh red blood before or after defecation; blood in stool; hemorrhoidal bleeding; quick-spreading blood drops before defecation (sign of wind); tongue: red; pulse: wiry and rapid.

Syndrome: Syndrome of bleeding.

Composition strategy:

  • for lower-body bleeding choose upward-moving herbs
  • combine heat-clearing and heat-dispersing herbs
  • light, gentle herbs ascend clear Qi and disperse constrained heat without forcing blood
  • each of the four herbs serves more than two functions

Dui Yao — Core Herb Pairs

The classical two-herb combinations at the heart of this formula, as recorded on the herbs' own pages — each pair has an action neither herb has alone.

Ce Bai Ye侧柏叶 + Huai Hua槐花

The combination cools the blood and stops bleeding more strongly than either alone, for heat-type intestinal bleeding.

Intestinal wind and toxic accumulation with bright red rectal bleeding; the formula also contains Jing Jie and Zhi Ke.

Energetics dose-weighted

The formula's overall nature, taste balance and channel reach, weighted by each herb's dose. Classical formulas often pair warm and cool herbs on purpose, so a net figure summarises the mix — it doesn't describe every herb in it.
