Known as the 'Prime Minister', the lungs control breath and energy and assist the 'King' heart with the circulation of blood. The Internal Medicine Classic states: 'Energy is the commander of blood; when energy moves, blood follows. Blood is the mother of energy; where blood goes, energy follows.' This intimate relationship between breath and pulse, blood and energy, is the basis of Chinese breathing exercises.
Breathing controls cellular respiration, and shallow irregular breathing is therefore a major cause of low vitality and insufficient metabolism. The lungs also control the skin, which 'breathes' via the opening and closing of pores and is responsible for adjusting body temperature through perspiration and shivering.
The skin is where the radiant energy of resistance emanates, forming the first line of defense against noxious environmental energies such as heat and cold. Flu and the common cold are caused by impairment of radiant skin energy's capacity to resist external invasion, and symptoms of these diseases usually settle in the lungs and bronchial tract.
Pallid skin and poor complexion are common indications of weak lungs. The nose is the external aperture of the lungs and the gate of breath. A clogged or runny nose is another indicator of ailing lungs.
Breathing directly controls the autonomous nervous system, and this relationship is the basis for almost every system of yoga and meditation. By regulating the autonomous nervous system and governing energy and pulse, breathing forms a direct bridge between body and mind and may be utilized to keep the two in balance.
Passage without points
The meridian originates from the middle warmer runs downward to connect with the large intestine meridian winds back to go through the upper orifice of the stomach passes through the diaphragm enters its pertaining organ the lung from there runs upward to communicate with the throat then comes out transversely.
Passage with points
LU 1 starts in the lateral aspect of the chest descends along the medial aspect of the upper arm passes in front of the pericardium and heart meridians reaches the cubital fossa then goes continuously downward along the anterior of the medial aspect of the forearm arrives at the styloid process of the radius passes the thenar eminence along its radial side ends at the medial side of the tip of the thumb (LU 11).
The branch proximal to the wrist emerges from LU 7 runs directly to the radial side of the tip of the index finger, where it links with the large intestine meridian.
The hand greater Yin (Taiyin) lung meridian starts in the region of the stomach in the middle warmer and descends to net the large intestine. It then returns upward through the cardiac orifice, passes through the diaphragm, and homes to the lung. Continuing its ascendant path, it passes through the respiratory tract into the throat, then veers downward following the clavicle to enter the axilla. From here it runs down the anterior aspect of the upper arm, lateral to the heart and pericardium meridians, traverses the cubital fossa, and continues along the anterior aspect of the forearm to the radial styloid process of the wrist. It crosses the wrist pulse (radial pulse), traverses the thenar eminence, and travels along the radial side of the thumb to its tip. A branch leaves the main pathway proximal to the wrist, passes round to the dorsum of the hand, and then runs down the inside of the index finger to its tip.
