Last updated October 1, 2026
Description
Mu Xiang Bin Lang Wan (Aucklandia and Betel Nut Pill), from the Dan Xi Xin Fa quoted from Zhang Zi He's formula, is used to promote Qi movement in the Large Intestine; purge accumulation and heat.
Presentation: food stagnation obstructing Qi with damp-heat; focal and general epigastric/abdominal distension, fullness and pain; constipation; dysenteric diarrhea with mucus and blood; tongue: red or purple with yellow sticky coating; pulse: strong.
Syndrome: Syndrome of Qi stagnation in the Stomach, Spleen and Large Intestine.
Composition strategy:
- all herbs strong and active, grouped by aspect of pathology
- treats diarrhea by purging the accumulation rather than astringing, which would prolong accumulation and worsen heat/damp
- blood-regulating and heat/toxin-clearing herbs directly address blood and mucus
Cautions:
- excess syndrome only; all herbs strong and harsh

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.
Nature
Net slightly cool (-0.35)
From 100% of the weighed grams.
Grams by band: cold 39%, neutral 17%, warm 44%.
Pairs warm and cool. 44% of the weighed grams are warm or hot and 39% cool or cold — the net is their average, not the whole story.
Small but decisive: Da Huang 15g (cold, 4% of the grams), Huang Lian 30g (cold, 9% of the grams), Huang Bai 30g (cold, 9% of the grams). Dose weighting nearly cancels a herb this small, but it may be what the formula is for.
Taste
- pungent 36%
- sweet 6%
- bitter 58%
From 100% of the weighed grams.
Channels reached
- Large intestine 56%
- Spleen 56%
- Liver 48%
- Stomach 39%
- Lung 26%
- Kidney 26%
Share of the grams entering each channel, from 100% of the weighed grams.
Dose-weighted from each herb's recorded nature, taste and channels (missing values are left out, never counted as neutral). It describes the composition — it is not a recommendation.
Preparation
Powder formed into water pills; 3-6g 2-3 times daily with warm water or a fresh-ginger decoction. May be decocted at proportionally reduced doses.

Each entry reads as the larger formula written out: “+” adds its other catalogue cores, then the herbs none of them hold. A catalogue formula counts as a core only when at least 80% of its herbs are present, no more than 1 is absent, and the absent herb is not its chief.
