Well done, Mr. Rawles!! Excellent info. I have been involved in survival skills for the last 30 years (former U.S. Army survival instructor) and have been a student of herbal medicine and wildcrafting for many years. I have an excellent source for herbal medicine information. The web site that belongs to the herbalist Michael Moore  (no, not THAT Michael Moore!) has tons of downloadable material which has an incredible amount of free herbal medicine information. I certainly hope this info may be of help to you and the survival minded community in general. Best Regards and may God bless you. – R.L.
