The 5 Elements: The four cycles
Two that sustain and two that spoil. 6 activities, about 14 minutes.
Generation: mother and child
相生 xiāng shēng
Each phase feeds the next one clockwise. From that comes the most used clinical rule in the system: if the child is deficient, tonify the mother.
- Wood feeds Fire
- wood burns
- Fire feeds Earth
- ash makes soil
- Earth feeds Metal
- ore comes out of the ground
- Metal feeds Water
- metal condenses dew
- Water feeds Wood
- water waters the shoot
Common mistake: Reciting the chain without using it. Its point is deciding whom to treat when the complaining organ does not respond.
Control: the star inside
相剋 xiāng kè
Besides feeding the next phase, each one restrains the phase two places on. It draws a star inside the circle and it is what keeps generation from running away.
- Wood controls Earth
- roots hold the soil
- Earth controls Water
- the bank contains the water
- Water controls Fire
- water puts fire out
- Fire controls Metal
- fire melts metal
- Metal controls Wood
- the axe prunes
Common mistake: Reading control as something bad. Without it each phase would grow until it smothered the rest.
When control breaks down
Control can fail in two ways and both have names. If the controller overdoes it, it crushes; if the controlled one gets bold, it rebels against the phase that should restrain it.
- Over-acting
- the restrainer presses too hard
- Insulting
- the restrained one pushes back
- Over-acting example
- a tense Liver attacking the Spleen
- Insulting example
- overflowing fire drying the water
Common mistake: Treating only the organ that complains. In over-acting, the one with symptoms is the victim, not the culprit.
A patient with heavy digestion and diarrhoea that always follow an argument. Which cycle explains it?
Which cycle describes each situation?
- Tonifying the Kidney so a dry Liver improves
- The Lung descending and restraining a rising Liver
- Sustained stress that ends in gastritis
- A very high Heart fire that exhausts Kidney water
- Strengthening the Spleen so the Lung stops relapsing
- A huge Spleen dampness that smothers the breathing
Order the generating cycle starting from the Kidney's phase.
- Water
- Wood
- Fire
- Earth
- Metal
