Dear Melissa, Just got a book from our local health food store (B&C) called Handbook for Herbal Healing ... a concise guide to herbal products. It seems to be an excellent source of information and inexpensive at that (on sale 2.95). It is written by a fourth generation herbalist...Christopher Hobbs. Has whole sections on herbs/pregnancy and herbs/children. He says echinacea is well known for use during pregnancy. He says use low to moderate dosing. Bought this book for my own info. Great book-very practical. Warmllly, Ilene (where it hit -30 around the Boston area last night with wind chill Brrrrrrrr!)
