About This Formula
Traditional Chinese Medicine background and properties
Formula Description
A modern clinical formula used to support gallbladder health by clearing heat and dampness from the liver and gallbladder system. It is commonly used for gallbladder inflammation, gallstones, and related digestive discomfort such as pain under the right ribs, nausea, bitter taste in the mouth, and yellowish skin or eyes.

- Benefits the Gallbladder
- Clears Heat and Resolves Toxicity
- Moves Qi and Alleviates Pain
- Disperses stagnation in the Gallbladder
TCM Patterns
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Li Dan Tang is traditionally associated with these specific patterns.
The following describes this formula's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Li Dan Tang addresses this pattern
This is the primary pattern addressed by Li Dan Tang. When damp-heat lodges in the Liver and Gallbladder, it obstructs the smooth flow of bile, causing it to stagnate and concentrate. Over time, this stagnation can lead to gallstone formation and gallbladder inflammation. The formula targets this pattern from multiple directions: Jin Qian Cao and Yin Chen Hao directly clear damp-heat and promote bile drainage; Huang Qin dries dampness and clears Gallbladder fire; Da Huang purges the accumulated heat downward; and the Qi-moving herbs (Chai Hu, Yu Jin, Mu Xiang, Zhi Shi) restore the free flow of Liver and Gallbladder Qi that damp-heat has obstructed. The toxin-clearing herbs (Jin Yin Hua, Da Qing Ye) address the toxic heat that manifests when the damp-heat becomes severe enough to cause infection and high fever.
A practitioner would look for one or more of these signs
Distending or sharp pain under the right ribs, often radiating to the right shoulder or back
Persistent bitter taste in the mouth, especially in the morning
Nausea and aversion to greasy or oily foods
Yellowing of skin and eyes when bile obstruction is present
Dark yellow or tea-colored urine
Fever with alternating chills in acute episodes
Dry stools or constipation from heat drying the intestinal fluids
Why Li Dan Tang addresses this pattern
When Liver Qi stagnates, it impairs the Gallbladder's ability to store and excrete bile normally. The stagnant Qi creates a predisposition for damp-heat to accumulate and for stones to form. Li Dan Tang addresses this through Chai Hu, which courses Liver Qi and resolves constraint; Yu Jin, which moves both Qi and Blood stasis in the flanks; and Mu Xiang with Zhi Shi, which break up Qi accumulation in the middle burner. By restoring smooth Qi flow, these herbs address the root mechanism that allows damp-heat to collect in the first place, and they relieve the characteristic distending pain of Qi stagnation.
A practitioner would look for one or more of these signs
Distending pain in the flanks that worsens with emotional stress
Feeling of fullness and bloating in the upper abdomen
Frequent belching or sighing
Poor appetite, especially aversion to fatty foods
How It Addresses the Root Cause
Li Dan Tang addresses a pattern where Dampness and Heat accumulate in the Liver and Gallbladder system, disrupting normal bile flow and causing inflammation and pain. In TCM understanding, the Gallbladder is responsible for storing and excreting bile (a "clear fluid"), and it functions properly only when Liver Qi moves smoothly and the Gallbladder channel is free of obstruction.
When a person eats excessive greasy or rich food, experiences prolonged emotional frustration (which stagnates Liver Qi), or is invaded by external Dampness-Heat, these pathogenic factors can brew in the Liver and Gallbladder. Dampness is heavy and sticky, while Heat is inflammatory and agitating. Together they create a turbid, congested environment where bile thickens, stagnates, and may eventually form stones or trigger infection. This manifests as pain and distension in the right upper abdomen and ribcage area, bitter taste in the mouth, nausea (especially after fatty meals), yellow greasy tongue coating, and in more severe cases, jaundice (yellowing of the skin and eyes).
The formula works by clearing this Dampness-Heat through two main routes: promoting bile secretion and flow ("benefiting the Gallbladder"), and draining the turbid Dampness-Heat downward through the intestines and urine. Simultaneously, it addresses the Qi stagnation that always accompanies Gallbladder disorders by moving Liver Qi and relieving pain. By resolving the root cause (Dampness-Heat accumulation) while also addressing the branch symptoms (pain, nausea, jaundice), the formula restores normal Gallbladder function.
Formula Properties
Cold
Predominantly bitter and cool, with some pungent elements. The bitter taste drains Dampness-Heat and promotes downward movement, while pungent herbs move stagnant Qi in the Liver and Gallbladder.
