First, protect the heart. Because the heart is connected with the pericardium through the membrane and is the peripheral organ of the heart, it has the function of protecting the heart. "Lingshu Xie Ke" said: "All evils are in the heart, and all are wrapped in the heart", which shows that pericardium can take the place of monarch to accept evil. When it is sick, it shows heart disease. Such as trance and delirium. Therefore, when exogenous pathogens invade the heart, the pericardium bears the brunt. Its acting monarch ordered. Because the yang of the heart spreads through the pulse of the pericardium, the heart can dominate the pericardium. But the role of the heart can only be played through the pericardium. So pericardium can act on behalf of the monarch.
The pericardium meridian is called the Hand Jueyin meridian. The meridian of hand jueyin originates in the chest and belongs to pericardium. It passes through the diaphragm circulation from the pericardium downwards, and connects the upper, middle and lower triple energizer from the chest to the abdomen in turn. Its chest branches run along the chest, out of the lateral abdomen, to the three-inch Tianchi point under the armpit, up to the armpit, and then along the inner side of the upper arm, between the Taiyin meridian of the hand and the Shaoyin meridian of the hand, into the cubital fossa, down from the cubital fossa between the two tendons of the forearm, into the palm, and along the middle finger to the midpoint of the fingertip.
The palmar branch originates from Laogong point in the palm, passes through Guanchong point from the ring finger to the fingertip, and meets the Sanjiao Meridian of Shaoyang in the hand here (see figure).
The physiological functions of the meridian of Hand Jueyin mainly include running the blood-blood connection of pericardium and nourishing tissues and organs closely related to pericardium. Because the meridian of hand jueyin originates from chest and belongs to pericardium. Therefore, blood gas mainly passes through pericardium. Therefore, there is a saying in Lingshu Jingpian that "the heart governs the hand pulse, and Jue Yin controls the heart collaterals". That is, it points out the physiological relationship between pericardium and hand Jue yin meridian. In addition, the meridian of Hand Jueyin belongs to the pericardium, which runs through the triple energizer and runs along the midline of the chest, hypochondrium and upper limbs, making it form a small organism with the pericardium. It transports the blood gas of pericardium to these tissues and organs, so that they can be moistened and nourished, thus completing their respective physiological functions. If the channels and collaterals of the Hand Jueyin Meridian are not functioning normally, there will be pericardial inflammatory diseases such as palpitation, upset and nerve disorder. Or symptoms such as fullness of chest and hypochondriac branches and upper limb spasm may occur. But at the same time, it must rely on the nourishment of blood gas in the pericardium to play its normal physiological function.
Zhongshan is not a substantial organ, but refers to the part between the breasts. "On the Development of Spiritual Pivot" said: "Those who are in the mountains are also the Miyagi of the heart." "On Ling Shu Hai" said: "Those caught in the middle are the seas of Qi." It can be seen that pericardium and air sea are contained in the stomach. What is the function of Zhongshan? Zhongshan has two main functions. Is the middle of the mountain is the sea of gas, the main gasification. Because Zhongshan is a place where clan spirit gathers, it is also called the sea of qi. Mainly acts on the heart and lungs. For the lungs, Qi Hai Zuling supports the breathing of the lungs and is the driving force of drum language. For the heart, the qi of qi and sea is the driving force to promote the blood circulation of the heart. Therefore, Qi-Hai can transmit Qi and blood to the heart and lungs, and coordinate Yin and Yang. Clinically, lung and heart diseases, such as chest tightness, wheezing, blushing, upset, etc., are prone to occur due to excessive qi and yang hyperactivity. If the qi and sea are insufficient, it is easy to have weak breathing, weak language and weak facial expression. (yellow) white, palpitation and other lung and heart diseases. This shows that Zhongshan is a gas sea with main gasification function. Second, Zhongshan is an official of the minister and acts on behalf of the monarch. An envoy is an official who commands the monarch's orders and will. In fact, Zhongshan is an official of the minister, which shows that Zhongshan can play a role, not a heart. The imperial edicts in the middle period of Zhongshan include the functions of heart seal and qi sea. Because the spread of heart fire must first pass through the pericardium, and then it can reach the Qi Sea, and it will play a role through the propaganda of Qi Sea. The normal declaration of heart fire can promote people's spiritual comfort and happiness. Therefore, the Sutra of Su Wen Ling Lan said: "Those who catch in the mountains, I will make them officials and have fun." This is also called.
