Herb Description*
Sandalwood heartwood is an aromatic, warming herb primarily used to relieve chest and stomach pain caused by cold and stagnation. It is valued for its ability to open up the chest and settle the stomach, and is commonly found in formulas for angina and digestive discomfort. Its pleasant fragrance also has a calming quality.

Main Actions*
- Moves Qi and Alleviates Pain
- Disperses Cold and warms the Middle Jiao
- Regulates Qi Flow in the Chest, Abdomen and Lower Body
- Harmonizes the Stomach and Stops Vomiting
How These Actions Work*
'Moves Qi and alleviates pain' means Tán Xiāng promotes the smooth circulation of Qi, particularly in the chest and upper abdomen. When Qi becomes stagnant (stuck or blocked), it causes pain, fullness, and discomfort. Tán Xiāng's acrid, aromatic nature penetrates and unblocks these areas, making it especially useful for chest pain, epigastric pain, and the sensation of tightness or oppression in the chest. It is a go-to herb for pain caused by Cold and Qi stagnation in the chest, and has been used in modern clinical practice for angina pectoris.
'Disperses Cold and warms the Middle Jiao' refers to Tán Xiāng's warm nature, which drives out Cold that has settled in the Stomach and Spleen. When Cold invades the digestive system, it can cause cramping abdominal pain, vomiting of clear watery fluid, and poor appetite. Tán Xiāng gently warms these organs and restores their normal function.
'Regulates Qi in the chest and diaphragm' highlights the herb's special affinity for the upper body. Classical texts describe it as being good at "adjusting the Qi above the diaphragm." Unlike Chén Xiāng (Agarwood), which primarily pulls Qi downward, Tán Xiāng lifts and spreads Qi upward and outward, opening up a congested chest and relieving the feeling of things being stuck in the throat or chest.
'Harmonizes the Stomach and stops vomiting' means Tán Xiāng helps settle a cold, rebellious Stomach. When Stomach Qi reverses upward instead of descending normally, it causes nausea and vomiting. Tán Xiāng's aromatic quality "awakens" the Spleen and Stomach, restoring the normal downward flow of digestion and relieving nausea, especially when the vomiting involves clear, watery fluid.
Patterns Addressed*
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Tan Xiang is traditionally associated with these specific patterns.
The following describes this herb's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Tan Xiang addresses this pattern
In this pattern, Cold pathogen lodges in the Stomach, congealing Qi and causing cramping pain with vomiting of clear fluid and poor appetite. Tán Xiāng's warm, acrid nature directly disperses the Cold while its aromatic quality "awakens" the Spleen and Stomach, restoring their digestive and descending functions. Its channel entry into the Spleen and Stomach makes it a well-targeted herb for this pathomechanism.
A practitioner would look for one or more of these signs
Cold, cramping stomach pain that improves with warmth
Vomiting clear, watery fluid
Poor appetite with no desire for food
Why Tan Xiang addresses this pattern
When Qi circulation becomes blocked in the chest, diaphragm, or epigastrium, it produces feelings of distention, oppression, and pain. Tán Xiāng is acrid and aromatic, giving it strong dispersing and penetrating qualities that break through Qi obstruction. Classical sources describe it as excelling at "adjusting Qi above the diaphragm," making it particularly suited for Qi stagnation manifesting in the chest and upper abdomen rather than in the Liver or lower body.
A practitioner would look for one or more of these signs
Chest pain or tightness from Qi obstruction
Epigastric fullness and bloating
Shortness of breath from chest constriction
Why Tan Xiang addresses this pattern
When Blood stasis combines with Qi stagnation in the Heart and chest vessels, it produces the fixed, stabbing pain of chest impediment (xiōng bì). Tán Xiāng enters the Heart channel and moves Qi powerfully through the chest, which in turn helps promote Blood circulation. While Tán Xiāng primarily targets the Qi aspect, its ability to open the chest makes it an effective supporting herb for Blood stasis patterns when paired with Blood-moving herbs like Dān Shēn.
A practitioner would look for one or more of these signs
Chest pain radiating to the back or left arm
Sensation of pressure or constriction in the chest
