What does Ye primarily nourish within the body?

Ye, often translated as "body fluids" or "essence," primarily refers to the more viscous and nourishing fluids within the body. It plays a crucial role in nourishing joints and marrow, which are essential for the overall structure and function of the body. Ye is particularly involved in moistening and lubricating areas where dryness could lead to discomfort or dysfunction, such as in the joints.

In Traditional Chinese Medicine, the nourishment provided by Ye is vital for maintaining the health of these areas, preventing issues such as joint pain or bone weakness, which often arise from a deficiency of these nourishing fluids. This is why it is understood that Ye's primary function is related to the joints and marrow, supporting their health and proper function in the body.
