Common adjustments

Sore throat prominent — add Jie Geng 桔梗 and Niu Bang Zi 牛蒡子
Stools not actually blocked — reduce or omit Mang Xiao 芒硝 and keep Da Huang small
Mouth sores recurring — add Sheng Di Huang 生地黄 and Dan Zhu Ye 淡竹叶
Fluids damaged — add Xuan Shen 玄参 and Mai Men Dong 麦门冬

Contraindications

Not for mouth sores or throat pain arising from yin deficiency fire, which recur and are worse when tired — purging would deplete further. Not for the elderly and frail, nor for loose stools.

For licensed practitioners’ reference only — not a self-treatment guide.

Pregnancy

Contraindicated in pregnancy — it contains both Da Huang and Mang Xiao, purgatives that are avoided during pregnancy and while breastfeeding.
