About This Herb*
Traditional Chinese Medicine background and properties
Herb Description*
Citron fruit is a gentle, aromatic herb used to ease digestive discomfort such as bloating, belching, nausea, and stomach pain caused by stress or emotional tension. It also helps loosen chest congestion and clear phlegm from the lungs. Because it works by moving stuck Qi and calming the digestive system, it is especially suited for people whose digestive problems worsen with stress or frustration.

How These Actions Work*
'Soothes the Liver and resolves depression' means Xiāng Yuán helps restore the smooth flow of Qi through the Liver system. When someone is emotionally frustrated, stressed, or irritable, the Liver's Qi can become stuck or "knotted." This shows up as pain or tightness along the sides of the ribcage, a feeling of a lump in the throat, or mood swings. Xiāng Yuán's pungent taste disperses this stuck Qi while its bitter taste helps push it downward and outward, relieving the congestion. It is commonly paired with herbs like Yù Jīn (Curcuma tuber), Fó Shǒu (finger citron), and Xiāng Fù (Cyperus tuber) for this purpose.
'Regulates Qi and harmonizes the Middle' means it restores the normal movement of Qi in the Spleen and Stomach (the digestive center or "Middle Burner"). When Qi stagnates here, people experience bloating, belching, acid reflux, nausea, loss of appetite, or epigastric pain. Xiāng Yuán's aromatic fragrance "wakes up" the Spleen, and its pungent-bitter nature moves stagnant Qi and promotes the Stomach's natural downward-moving function. It is combined with herbs like Mù Xiāng (Costus root), Shā Rén (Amomum), and Chén Pí (Tangerine peel) to strengthen this effect.
'Dries Dampness and transforms Phlegm' means Xiāng Yuán helps the body break down and clear accumulated Phlegm, particularly in the Lungs and chest. When Qi stagnation and Dampness combine, thick mucus can build up, causing coughing with copious sputum and a heavy, congested feeling in the chest. The herb's bitter taste dries Dampness and its warm nature helps dispel cold Phlegm. It is often used with Bàn Xià (Pinellia) and Fú Líng (Poria) for this indication.
Patterns Addressed*
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Xiang Yuan 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 Xiang Yuan addresses this pattern
Xiāng Yuán directly addresses Liver Qi Stagnation through its pungent, dispersing nature and its affinity for the Liver channel. When the Liver's Qi becomes stuck (often due to emotional stress or frustration), it fails to flow smoothly, causing pain and distension in the chest and ribcage area. Xiāng Yuán's pungent taste scatters the bound-up Qi while its bitter taste promotes the Liver's natural spreading and draining function. Its warm temperature gently activates Qi movement without being overly drying. Although it is milder than some other Qi-moving herbs, its aromatic quality makes it particularly suited for patterns where the stagnation causes a stuffy, oppressive sensation in the chest.
A practitioner would look for one or more of these signs
Distending pain along the sides of the ribs (胁肋胀痛)
Stifling sensation in the chest
Emotional irritability and frustration
Frequent sighing or desire to take deep breaths
Why Xiang Yuan addresses this pattern
Xiāng Yuán's aromatic fragrance "awakens" the Spleen, and its combined pungent-bitter taste moves stagnant Qi in the Middle Burner (Spleen and Stomach). When Qi stagnates in the digestive system, the Stomach cannot descend food properly and the Spleen cannot transform nutrients, leading to bloating, nausea, and poor appetite. The herb's warm temperature and bitter flavor promote the Stomach's natural downward movement, helping to relieve belching, acid reflux, and vomiting. Its entry into the Spleen channel makes it a natural fit for resolving the fullness and distension that characterize this pattern.
A practitioner would look for one or more of these signs
Epigastric and abdominal distension and fullness
Frequent belching or acid reflux
Nausea or vomiting
Reduced appetite and poor digestion
Why Xiang Yuan addresses this pattern
Xiāng Yuán addresses Damp-Phlegm accumulation through its ability to both dry Dampness and regulate Qi. In TCM theory, Phlegm is often generated when Qi stagnation impairs the Spleen's ability to transform fluids, allowing Dampness to congeal into Phlegm. Xiāng Yuán's bitter taste dries this Dampness while its warm temperature helps dispel cold Phlegm. Its pungent nature opens the Lung Qi (since it also enters the Lung channel), which is essential because the Lungs govern the downward movement of fluids and the dispersal of Phlegm. By simultaneously moving Qi and transforming Phlegm, it breaks the cycle of Qi stagnation breeding more Phlegm.
A practitioner would look for one or more of these signs
Coughing with copious, thick sputum
Heaviness and congestion in the chest
Wheezing or laboured breathing from Phlegm obstruction
