Fascinating! I was always accustomed to Western doctors or even TCM folks being generalists, but I'd never thought about someone specializing in just a handful of herbs. It makes a lot of sense though.

Out of curiosity, how would you go about selecting the ones to focus on? Would they be the ones that are local to you? That you grow yourself? Or perhaps some that you have used and found useful for yourself and your family? Some other criteria?
