Yin, Yang and the 12 Meridians
There are 12 regular meridians. The meridians are organized into six Yin and Yang pairs.
Meridian Pairs of Chinese Medicine:
1. Yin: Lung
2. Yang: Large Intestine
3. Yin: Spleen
4. Yang: Stomach
5. Yin: Heart
6. Yang: Small Intestine
7. Yin: Kidney
8. Yang: Bladder
9. Yin: Pericardium
10. Yang: San Jiao (Triple Warmer)
11. Yin: Liver
12 Yang: Gallbladder
What is the difference between the Yin and Yang Meridians?
Compared to Yang, Yin is dense while Yang is hollow.
All Meridians are extensions of Organs.
The Yin Organs are more dense compared to the Yang Organs. Notice that the Yang Organs are hollow – the intestines, bladder, and gallbladder are tubes or sacs. This is in contrast to the Yin Organs that are dense in structure.
But what about the Heart?
The Heart is Yin but has chambers, so shouldn’t it be Yang?
Not all Yin Organs are alike. Every Organ has its own particular nature. Some of the nature or characteristics of an Organ come from the Element that it is associated with. The Heart is associated with the Fire Element, which is the most active of all of the 5 Elements. Notice that the Heart is denser than its Yang partner, the Small Intestine. So even though the Heart is very active, it is a Yin Organ.
