Where does the pericardium meridian begin and end?

The pericardium meridian, also known as the heart protector, is a key pathway in traditional Chinese medicine that plays a crucial role in the heart's health and emotional well-being. This meridian indeed starts at the nipple (specifically in the middle of the chest) and travels down the inner arm, ultimately ending at the tip of the third finger (the middle finger).

This pathway is significant because it reflects the meridian's function of protecting and nurturing the heart, which is seen as having both physiological and emotional aspects in traditional Chinese medicine. The involvement of the middle finger is particularly noteworthy, as this digit is often associated with balance, expression, and communication, all of which are essential elements in the context of heart health.

Recognizing where the pericardium meridian begins and ends reinforces the understanding of its clinical relevance, helping practitioners identify potential pathologies related to heart health, emotional states, and other related conditions. Thus, by knowing the correct trajectory of the pericardium meridian, acupuncture practitioners can effectively target treatments that benefit the heart and its associated systems.
