P-8 is known as which type of point?

P-8, also known as the Palmaris Longus or "Shenmen," is classified as a Ying Spring point. Ying Spring points are located on the channels where Qi is deeper and more nourishing compared to other points. They are typically situated on the meridians at the level of the wrist or on the forearms and are associated with the transformation of Qi and blood, taking part in the overall nourishment of the body.

This classification is significant in acupuncture practice as Ying Spring points often have a strong effect on the corresponding organ's Yin and Yang, facilitating the movement and cooling of the Qi. Thus, P-8 being labeled as a Ying Spring point indicates its important role in treating conditions related to the heart and its connection to emotional aspects, such as anxiety or insomnia, aligning with its naming and traditional uses in TCM (Traditional Chinese Medicine). In this context, it is essential to understand its therapeutic implications and how it can be effectively employed in clinical practice.
