Herb books range dramatically in there quality, cost and applicability to lactation. Personally, I'd recommend Dorling Kindersley's MEDICINAL HERBAL book for a beginner. It's not very technical, but does provide more detail than Susun Weed's HERBS FOR THE CHILDBEARING YEAR. There are many others that are more technical that I use for the chemistry side to assess the safety, but I'm not sure of your background. : )Chris Hafner-Eaton, PhD, MPH, CHES, IBCLC email: [log in to unmask] : ) : )HSR & Health Educational Consultant voice/fax: 541 753 7340 : ) : )------------**CHANGE THE WORLD, NURTURE A CHILD!**------------------ : )
