The Lungs(肺) and the lung meridian(肺经)
The functions of the lungs
- The lungs govern Qi (肺主气)
- the lungs govern breathing, they take in the clear Qi from the nature and expel the turbid Qi from the body. They are in charge of the exchange of the “new” and the “old” of the body(吐故纳新).
- the lungs govern all the Qi of the body(there are different types of Qi in the body, and all organs have their own Qi too). For example, the lungs take in the clear Qi and send it to the digestive organs, help them to transform food and liquid into “Qi of water and grain”.
- The lungs correspond with all blood vessels (肺朝百脉)
- what this means is that the heart is in charge of the movement of the blood, this movement requires Qi as energy, and the engery-Qi comes from the lungs.
- The lungs regulate the water passage of the body
- the lungs are the upstream and upper source of water that the body needs.
- The lungs disperce and descend
- this meand the lungs spread clear Qi to the whole body, are in charge of sweating and send water down through out the body. (the lungs are on the top of other organs, so they are called “the canopy” or the “the marquee”, so they send water “down”).
The Lung Meridian(手太阴肺经)
The lung meridian starts in the middle burner(中焦, the midsection of the torso), then:
- move downward to connect with the large intestine
- winds back up, passes the diaphragm, the stomach, the lungs and comes out through the throat
- from the throat, it goes downward following the clavicle to enter the axilla, then runs down the anterior aspect of the upper arm, 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.
The lung is related to the season of the fall, the emotion of sorrow, the taste of spicy, and the color of white.
There are 11 points on the lung meridian, and they treat:
- Common cold
- Pain in the regions that on the meridian pathway
