Which organ primarily controls muscle according to TCM?

In Traditional Chinese Medicine (TCM), the Spleen holds a crucial role in controlling muscle health and function. It is considered the source of postnatal energy and is responsible for the production of Qi (vital energy) and Blood from the food we digest. This process is essential for nourishing the muscles and providing them with the strength and energy required for movement and activity.

The Spleen also plays an integral part in the transformation and transportation of nutrients throughout the body, which supports muscle development. A well-functioning Spleen leads to the adequate generation of Blood that circulates to the muscles, while a deficiency can lead to weakness, atrophy, or fatigue of the muscles.

In contrast, other organs like the Liver, Heart, and Kidneys have different primary functions in TCM. The Liver is associated with the smooth flow of Qi and blood, the Heart governs blood circulation and houses the Shen (mind/spirit), and the Kidneys control growth, development, and reproduction. While these organs can influence muscle condition indirectly through their various roles, they are not the primary organ responsible for muscle control like the Spleen is. This underscores the unique perspective of TCM on the interconnectedness of organ systems and their functions.
