Huai Hua San槐花散
Sophora Japonica Flower Powder
Ingredients4 herbs
Indications
Wind-heat or damp-heat toxin obstructing the intestinal tract and injuring its vessels. Heat scatters blood out of the collaterals of the large intestine, so it appears with the stool.
Clinical Manifestations
- Bright red bleeding before or with the stool
- Bleeding haemorrhoids
- Blood in the stool from wind-heat
- Dark blood mixed into the stool from damp-heat toxin
Health Categories
Modern Applications
Common adjustments
- Damp-heat marked with a sticky coating — add Di Yu 地榆 and Huang Qin 黄芩
- Bleeding heavy — add Xian He Cao 仙鹤草 and charred Ce Bai Ye 侧柏叶
- Constipation with dry hard stool — add Huo Ma Ren 火麻仁 to moisten the intestines
- Long-standing case with qi deficiency and prolapse — pair with Bu Zhong Yi Qi Tang rather than continuing to cool
Contraindications
Not for rectal bleeding from deficiency-cold or from qi failing to hold blood — pale dilute blood in a tired, cold patient with loose stools needs warming and tonification instead. Because it is cooling and dispersing it is not suitable for long-term use. Rectal bleeding at any age needs a diagnosis: haemorrhoids are common, but so are polyps and colorectal cancer, and the formula treats a symptom rather than its cause.
For licensed practitioners’ reference only — not a self-treatment guide.
Pregnancy
Used with caution in pregnancy and only on a practitioner's direction. Haemorrhoidal bleeding is common in pregnancy, but Huai Hua is cooling and downward-moving and Zhi Ke moves qi downward, neither of which is ideal once pregnancy is advanced. Any rectal bleeding in pregnancy should be examined rather than assumed to be haemorrhoids. There is no established interaction with anticoagulant medication, though a patient on such a drug who is bleeding should be reviewed by the prescriber.
