Intriguing quote at the top of this section: If the student can be made to understand the principles of scientific treatment of tissue-states...his judgement as to prescribing comes to him as if by intuition, and can scarcely be wrong. Matthew Wood gives a brief history and reason for the language of energetics that he presents - and that many folk herbalists use today, thanks to him. He then goes on to give great information about each tissue state. I appreciate the opportunity to learn and use this common language with the wonderful herbalists around me! And maybe it can seep out a bit into the non-herbal world, too, as a new way of looking at health and wellness, as well as "un-health" and how to deal with that.
