The problem is that Eastern medicine is also full of complete horse shit. How do you differentiate between the good and the bad without just reinventing from base principles?
But what I do find to be a little misguided is what I pointed out from the author's statement. There is a tendency in western circles to push away everything and not only just try to recreate based on first principles, but push those first principles away as well. The author was pondering a question that millions before her have done the practice of, without looking to any of those millions for a guide. Instead, I'd say listen to them, practice it, and if it doesn't work, discard it.
