I know everything can be categorized into the 5 elements. Also when using the Ba Gong method I see other organs. After all we have many organs. Now how exactly does TCm approach the 5 organs. And some are yin and some yang. And also the organs that are not the 5? The stomach isn’t nor the brain, one of the 5 organs. Basically, I am asking. Do all diagnosis have to involve one or more of the 5 organs?
