Liu Jun Zi Tang: The Six Gentlemen Formula and Its Origins
Six herbs, one classical formula — prepared fresh in our Toronto facility
Liu Jun Zi Tang, the Six Gentlemen Formula, is one of the most widely used digestive tonics in classical Chinese medicine. If you have encountered Si Jun Zi Tang — the Four Gentlemen — you already know its foundation. Liu Jun Zi Tang builds on those four herbs by adding two more, creating a remedy that addresses both digestive weakness and phlegm accumulation.
The name comes from a long tradition in Chinese medicine. Chinese medicine practitioners called well-balanced, effective herbs “gentlemen,” because they work with the body rather than forcing a response. The six herbs in this formula are: Korean red ginseng root (Ren Shen), white atractylodes root (Bai Zhu), poria fruiting body (Fu Ling), honey-fried licorice root (Gan Cao), chen pi peel (Chen Pi), and pinellia tuber (Ban Xia). The name Liu Jun Zi Tang translates to the Six Gentlemen Formula, a direct reference to these six herbs working in concert.
How the Six Herbs Work Together
The first four herbs form Si Jun Zi Tang. Together, they tonify Spleen and Stomach Qi — the core of digestive energy in TCM. The final two herbs add the Er Chen component. Specifically, chen pi dries dampness and moves Qi. Pinellia transforms phlegm and helps the Stomach descend its Qi normally. Additionally, pinellia is one of the more targeted herbs in classical Chinese medicine for calming nausea driven by a rebellious Stomach.
In TCM theory, the Spleen governs the transformation and transport of food and fluids. When Spleen Qi weakens, the body cannot move fluids properly. As a result, those fluids accumulate as dampness and phlegm over time. For this reason, Liu Jun Zi Tang addresses both the root and the symptom — it strengthens the Spleen while clearing the phlegm its weakness produces.
Historically, the formula draws from Li Dongyuan’s Spleen-Stomach school of Chinese medicine, which developed in the Jin-Yuan dynasty (1115–1234 CE). His work established that digestive strength was central to overall health. Furthermore, Liu Jun Zi Tang remains one of the most commonly prescribed TCM digestive formulas in global clinical practice. Practitioners in East Asia, Europe, and North America use it regularly. At Herbal Clinic, we offer it as a liquid extract made from all six classical herbs.
What the Liu Jun Zi Tang Six Gentlemen Formula Is Traditionally Used For
Liu Jun Zi Tang liquid extract — six classical herbs in a single formula
Practitioners most often choose the Six Gentlemen Formula, Liu Jun Zi Tang, for a TCM pattern known as Spleen Qi deficiency with phlegm-dampness. This pattern describes a digestive system that is both weak and producing excess phlegm or fluid accumulation. However, the formula’s reach extends beyond any single pattern. Practitioners choose Liu Jun Zi Tang, the Six Gentlemen Formula, when digestive weakness has progressed to include visible phlegm signs that Si Jun Zi Tang alone would not clear.
Four Main Actions in Classical TCM
In classical TCM, this formula has four main actions:
- Tonifies Spleen and Stomach Qi — supports the digestive system at its root, helping the body extract energy from food
- Dries dampness — chen pi resolves fluid accumulation that accompanies Spleen weakness
- Transforms phlegm — pinellia clears phlegm from the middle jiao, which may reduce sensations of fullness and nausea
- Harmonizes the Stomach — the combined formula calms Stomach Qi and supports its normal downward movement
This is where it gets interesting:
Compared to Si Jun Zi Tang, the Six Gentlemen formula adds a phlegm-clearing dimension. Compared to Xiang Sha Liu Jun Zi Tang, it lacks the Qi-moving and food-accumulation herbs. So Liu Jun Zi Tang sits in the middle — broader than the Four Gentlemen, more focused than the full Eight Gentlemen variant.
Modern research on Liu Jun Zi Tang has explored its traditional applications in functional gastrointestinal conditions. A number of studies indexed on PubMed have examined its use in chronic gastritis, functional dyspepsia, and digestive recovery after illness. In particular, researchers have noted its effects on gastric motility and its role in supporting digestive function during and after medical treatment. Nevertheless, this research reflects ongoing investigation, not established medical conclusions.

How to Take the Liu Jun Zi Tang Six Gentlemen Formula
Chen pi and pinellia root — the two herbs that distinguish the Six Gentlemen from the Four Gentlemen
Liu Jun Zi Tang, the Six Gentlemen Formula, comes as a liquid extract at Herbal Clinic. This format preserves a broad range of active compounds from all six herbs and makes consistent use straightforward. Consistent use over weeks matters for TCM tonic formulas — they work gradually by building and supporting the underlying system, not by producing an immediate acute effect.
How We Prepare the Formula
At Herbal Clinic, we prepare the Liu Jun Zi Tang Six Gentlemen Formula using the six classical ingredients: Korean red ginseng root, white atractylodes root, poria fruiting body, honey-fried licorice root, chen pi peel, and pinellia tuber. We extract them in reverse osmosis water and gluten-free pharmaceutical grade alcohol at a 1:5 ratio. In this way, we keep the formula close to its classical preparation and preserve the full activity of each herb.
Unlike single-herb tinctures, this is a compound formula where each herb plays a specific role. For this reason, removing or substituting any of the six herbs changes what the formula does. We follow the classical composition exactly so the formula works as generations of TCM practitioners intended.
Furthermore, because Liu Jun Zi Tang is a tonic rather than an acute formula, practitioners generally recommend taking it over a longer period. How long, and whether the Six Gentlemen formula fits your individual pattern, is a question best answered by a TCM practitioner or naturopathic doctor.
We do not make dosage recommendations for regulatory and liability reasons. Please review our disclaimer and consult a qualified health practitioner for guidance.

Liu Jun Zi Tang comes in 100mL, 250mL, 500mL, and 1000mL sizes. We ship across Canada. You can also explore Xiang Sha Liu Jun Zi Tang if you want the expanded version that also targets Qi stagnation and food accumulation.
