SECTION 2 PART 2: The Functions of the Stomach
Importance of the Stomach
The Stomach is deemed the most crucial of all Yang organs, playing a central role in digestion and overall health.
In conjunction with the Spleen, referred to as the ‘Root of Post-Heaven Qi’, it represents the origin of all Qi and Blood post-birth, crucial for sustaining life. This contrasts with Pre-Heaven Qi, which is formed at conception and contributes to one's inherent vitality.
Key Textual References:

- ‘Simple Questions’ Chapter 11 outlines the Stomach as the Sea of water and grains, vital for nourishing not only the 6 Yang organs but also for maintaining the body's overall balance.
Functions of the Stomach
The functions of the Stomach are categorized under various headings:
- The Stomach controls ‘receiving’, ensuring proper intake and processing of food and drink.
- It oversees the ‘rotting and ripening’ of food, breaking it down into usable forms.
- The Stomach controls the transportation of food essences throughout the body, distributing vital nutrients. - It governs the descending of Qi, essential for effective digestive processes.

The Stomach Controls ‘Receiving’
Function Overview:
- The Stomach’s primary role is to receive food and drink, ensuring they are held downwards for proper digestion.
- Concept of ‘Receiving’:
- This goes beyond mere ingestion; it encompasses the ability to retain and process food effectively.
- It is often referred to as the ‘Great Granary’ and ‘Sea of Food and Drink’, emphasizing its essential role in nutrient storage.
- The ‘Spiritual Axis’ highlights that the Stomach is crucial for drawing in Qi from the consumed food. - Relation to Appetite:
- A good appetite indicates a strong and healthy Stomach ‘receiving’ function, essential for maintaining energy levels. - Conversely, a poor appetite signifies weakness; the total absence of appetite indicates a collapse of this vital function, which can lead to significant health issues. - Symptoms such as belching, nausea, and vomiting arise from a weak Stomach function, indicating underlying digestive problems. - Key Quotes:
- According to Yu Jia Yan, the strength of Stomach-Qi is directly linked to the health of the five Yin organs, reflecting the interconnectedness of bodily systems.
- Zhang Jie Bin states that healthy Stomach-Qi is foundational for nourishing life; thus, its tonification is critical in treatments. - Recommended tonification points for treatment include ST-36 (Zusanli) and SP-6 (Sanyinjiao).
The Stomach Controls the ‘Rotting and Ripening’ of Food
Function Overview:
- The Stomach plays a pivotal role in macerating food, facilitating its breakdown through both mechanical and chemical processes.
- This process is vital for the extraction of Qi and Blood, with Food-Qi (Gu Qi) being a crucial output. - A strong Stomach-Qi is associated with a positive prognosis and overall well-being; when Stomach-Qi is weak, it may reflect or lead to health issues. - The condition of the tongue coating is an important indicator of Stomach-Qi status:
- A normal tongue coating suggests a healthy Stomach and efficient digestive function. - Illustration of Function:
- Food is transformed within the Stomach before being transferred to the Small Intestine for further processing.
- Traditional texts underscore the Stomach as the origin of the body’s Qi, which is foundational for sustaining life.
- The notion prevails: ‘If there is Stomach-Qi, there is life; without it, there can be none.’
The Stomach Controls the Transportation of Food Essences
Overview of Function:
- In conjunction with the Spleen, the Stomach is responsible for distributing food essences throughout the body, serving as a critical component in energy metabolism.
- A weak Stomach can lead to inadequate supply of food essences, resulting in fatigue and diminished vitality. - The activity of the Stomach contributes to the formation of ‘dirty dampness’, which impacts the condition of the tongue coating:
- A thin white coating typically indicates normal Stomach function; variations in color provide insights into potential pathologies that may require intervention. - A thick white coating can indicate Cold, while a thick yellow coating may indicate Heat within the body, providing vital clues for diagnosis.
The Stomach Controls the Descending of Qi
Movement of Qi:
- The Stomach is responsible for sending transformed food downwards to the Small Intestine, helping maintain proper digestive flow and preventing stagnation.
- Healthy Stomach-Qi movement is essential to facilitate digestion and prevent discomfort; impaired movement can lead to symptoms such as fullness, sour regurgitation, belching, and nausea. - Treatment Points:
- Ren-10 (Xiawan) is particularly effective for stimulating the downward movement of Qi, addressing issues related to Qi stagnation. - The Stomach is aligned with the Earth element, commonly associated with balance, nourishment, and stability within the body's environment. - Liver's Role:
- The Liver also plays a significant role in aiding the descending of Stomach-Qi; any stagnation in the Liver can lead to subsequent digestive complications.
The Stomach is the Origin of Fluids
Role of Fluids:
- The Stomach requires an adequate intake of fluids for effective food processing and digestion, which is essential for maintaining hydration and metabolic health.
- It governs the condensation of Body Fluids derived from ingested elements, contributing to overall fluid balance in the body.
- Clinical Indicators:
- Ample fluids improve digestion, while deficiencies can lead to discomfort, dryness, and potential digestive disruptions. - Connection with the Kidneys:
- The Kidneys are referred to as the ‘Gate of the Stomach’, emphasizing their role in transforming fluids in the Lower Burner, highlighting the interdependence of these organs. - Chronic deficiencies in fluids might lead to concurrent weaknesses in both Stomach and Kidney-Yin, complicating treatment approaches.
Other Aspects of the Stomach
Mental Influence:
- Overactivity in the Stomach may give rise to Excess patterns such as Fire or Phlegm-Fire, leading to various psychological effects and symptoms:
- Mental health can manifest as social withdrawal, hyperactivity, irritability, or even mania, indicating how physical health can impact mental well-being.Dream Interpretation:
- The ‘Spiritual Axis’ notes that dreaming of large meals often relates to Stomach deficiency, indicating unmet nutritional needs or imbalances in the digestive system.
