For herbal remedies, I love Rosemary Gladstar and Christopher Hobbs. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/winky.gif" style="border:0px solid;" title="Wink">
For dealing with illnesses, I really like Smart Medicine for a Healthier Child by Janet Zand. Apparently there's an adult version as well but I don't have it.<br><br>
I also like The Healing Power of Minerals, Special Nutrients and Trace Elements by Paul Bergner. Not for dealing with illness directly, but lots of discussion on minerals and their interactions.
