About This Herb
Traditional Chinese Medicine background and properties
Herb Description
White cardamom is a warm, aromatic herb widely used in Chinese medicine to settle the stomach, relieve nausea and vomiting, and ease bloating. It works by transforming internal dampness and promoting the smooth flow of Qi through the digestive system. It is also a popular culinary spice valued for its fragrant, slightly cooling taste.

Main Actions
- Transforms Dampness and Moves Qi
- Warms the Middle Burner and Stops Vomiting
- Opens the Stomach and promotes digestion
- Transforms Turbidity
How These Actions Work
'Transforms Dampness and moves Qi' means Bái Dòu Kòu uses its aromatic, pungent nature to cut through the heavy, stagnant quality of internal Dampness that clogs the digestive system. When Dampness obstructs the Spleen and Stomach, people feel bloated, heavy, have a poor appetite, and may notice a thick greasy coating on their tongue. This herb's fragrant volatile oils 'awaken' the Spleen and get Qi moving again, relieving that stuck, waterlogged feeling in the abdomen and chest. It is considered a key herb for the upper and middle portions of the body (the chest and upper abdomen).
'Warms the Middle Burner and stops vomiting' means this herb gently warms the Stomach when it has been affected by cold, helping to calm rebellious Qi (Qi that moves upward when it should descend). This makes it especially useful for nausea and vomiting caused by cold conditions in the Stomach, such as vomiting clear fluid, nausea after eating cold foods, or morning sickness. Classical texts note it can be used alone as a powder for acute vomiting, or combined with herbs like Huò Xiāng and Bàn Xià.
'Opens the Stomach and promotes digestion' refers to its ability to stimulate appetite and help break down food that sits undigested in the stomach. When someone loses interest in eating, feels full after only a few bites, or has food sitting in their stomach causing discomfort, this herb's warm and aromatic properties help restore normal digestive function. Modern pharmacological research has confirmed that it promotes gastric secretion and stimulates intestinal movement.
Patterns Addressed
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Bai Dou Kou 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 Bai Dou Kou addresses this pattern
When Dampness accumulates in the Spleen and Stomach, it blocks the normal flow of Qi, leading to a feeling of fullness and stuffiness in the chest and abdomen, poor appetite, and a heavy, tired body. Bái Dòu Kòu's pungent and aromatic nature directly targets this pathomechanism: the aromatic quality penetrates and dissolves turbid Dampness, while the pungent warmth moves stagnant Qi. Because it enters the Lung, Spleen, and Stomach channels, it can address Dampness affecting both the upper and middle areas of the body. Classical texts describe it as a key herb for the middle and upper Burners when Dampness and Qi stagnation coexist.
A practitioner would look for one or more of these signs
Epigastric and abdominal distension
No desire to eat
Stifling sensation in the chest
Nausea with greasy tongue coating
Why Bai Dou Kou addresses this pattern
When the Stomach is invaded by Cold, its descending function is impaired and Qi rebels upward, causing nausea, vomiting, and pain. Bái Dòu Kòu's warm temperature directly counters the Cold that has lodged in the Stomach, while its pungent taste promotes the movement and dispersal of Cold stagnation. Its specific ability to redirect rebellious Stomach Qi downward makes it one of the go-to herbs for vomiting due to Cold in the Stomach, including vomiting of clear fluids, vomiting after cold food intake, and infantile vomiting of milk.
A practitioner would look for one or more of these signs
Vomiting of clear or watery fluid
Cold pain in the stomach area relieved by warmth
Hiccups or belching from Stomach Cold
Why Bai Dou Kou addresses this pattern
In the early stages of Damp-Warmth (a type of febrile disease where Dampness and Heat combine), Dampness can be the dominant pathogen. Bái Dòu Kòu is described as 'warm but not drying,' making it suitable even for conditions where some Heat is present alongside heavy Dampness. Its aromatic action cuts through the turbid Dampness that traps Heat in the Qi level, while its ability to move Qi helps restore the normal transformation and transportation functions of the Spleen. It is a central herb in Sān Rén Tāng, the classic formula for the early stage of Damp-Warmth disease.
A practitioner would look for one or more of these signs
Chest oppression with no hunger
Body heaviness and fatigue
Afternoon fever that is low-grade
