What is the Yuan Source point associated with Heart function?

The Yuan Source point associated with Heart function is indeed H9, known as the Jing-Well point of the Heart. In Traditional Chinese Medicine (TCM), each organ has a designated Yuan Source point, which serves as a vital access point for the organ's qi, allowing practitioners to influence the organ's function directly.

H9, located at the radial side of the little finger, is particularly important for enhancing the Heart's functions of nourishing the blood, calming the mind, and promoting emotional well-being. This point can be beneficial for conditions related to the Heart, such as palpitations or emotional disturbances. Its connection to the Wood element also emphasizes growth and transformation, further supporting emotional balance.

The other options, while related to various Heart functions, do not serve as the primary Yuan Source point for the Heart: H6 addresses night sweats, H7 is used for insomnia and calming the mind, and H4 focuses on symptoms related to the Jing River. Each of those points may be utilized in treating specific conditions, but H9 is uniquely positioned as the Yuan Source point for directly influencing the Heart's function.
