five phlegms are:
The sustaining phlegm that resides in the chest, sustains all other four phlegms; its function is to move all body fluids.
The decomposing phlegm that resides in that part of the stomach where the food is not yet digested, whose function is to grind all kinds of foods.
The tasting phlegm that resides in the tongue, helps to be aware of tastes.
The satisfying phlegm that produces the satisfaction feeling resulting from whatever is good in life.
The connective phlegm that resides in the joints, allows us to move them. When it does not function well we experience pain and joint problems.
