The difference between the Heart Meridian and the Pericardium Meridian is that the meridian circulation and the main treatment are different. 1. Meridian circulation: the Shao Yin Heart Meridian starts from the heart, passes through the diaphragm and contacts the small intestine. The pericardium meridian of the syncopal yin of the hand starts from the chest and belongs to the pericardium, passes through the diaphragm, passes through the chest, the upper abdomen and the lower abdomen, and connects to the San Jiao. 2. Treatments: The Heart Meridian of the Shao-Yin Hand treats conditions of concern, such as yellowing of the eyes, dystocia (pain in the area of coats of arms and ribs), pain in the upper arm, pain in the posterior border of the inner forearm, syncope of cold, and warmth and pain in the heart of the palm. The pericardium meridian of the syncopal region of the hand deals with conditions that occur in the “pulse” area, such as irritability in the heart, heart pain, and heat in the palms. For specialized medical questions, it is advisable to consult a doctor.
