Common adjustments

Heat toxin escalating, high fever and severe pain — the picture belongs to Lan Wei Qing Jie Tang 阑尾清解汤
Constipation with abdominal fullness — increase Da Huang 大黄, added late in the cooking
Stasis pain still fixed and sharp — increase Tao Ren 桃仁 and Chi Shao 赤芍

Contraindications

Does not replace surgical assessment; perforation, gangrene and peritonitis are surgical. The formula is cold and bitter throughout and is unsuitable for a deficiency-cold middle burner or for prolonged use.

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

Pregnancy

Contraindicated in pregnancy. It combines a purgative (Da Huang) with blood-movers (Tao Ren, Chi Shao, Mu Dan Pi) and heavy cold herbs; none of that is appropriate in pregnancy, and abdominal pain in a pregnant patient needs urgent assessment instead.
