I would say every great MD or author was a result of their own disease. Most every book I have read that was good all started with how the author cured them selves.
You would do well to watch the entire Master Herbalist tapes and others I have, they give you allot of ideas and stories. I play them as I work instead of the radio. The Second book has been done, I just have not had time to punch the holes and bind them, I gurantee you that if your becoming a MD, the second book is going to blow you away as you will be learning a system that odds are you have no idea about and may answer many questions about your own health and the health of this world.
