What does the ST (Stomach) control in Traditional Chinese Medicine?

In Traditional Chinese Medicine, the Stomach is primarily associated with the function of controlling the receiving and descending of Qi. This function is crucial for digestion, as the Stomach is responsible for processing food after it has been ingested. Once food enters the Stomach, it is broken down and prepared for the Spleen to transform and transport the nutrients. The downward movement of Qi is essential for the proper digestion process, allowing the Stomach to not only receive food but also to ensure that Qi and bodily fluids descend correctly for further processing by the digestive organs.

In this context, the Stomach's role is essential in maintaining balance and harmony within the digestive system, as it helps in directing the movement of food and energy. This descending action of Qi is vital for preventing problems such as nausea or reflux, which can arise when the Qi does not flow appropriately in the digestive tract.

The other functions mentioned relate to different organs or concepts within Traditional Chinese Medicine. While the Stomach does play a role in these areas, its primary function is focused on the receiving and descending aspects of Qi.
