Kathy and all, The comments that I posted about St. John's Wort were those of the author of the book Hypericum (St. John's Wort) and Depression-- Peter McWilliams. He did not give any references. I had e-mailed him from their website and what I posted on Lactnet is what I copied from his response. His answer was part of his "personal notes on Hypericum". I will try to write back to him and ask these questions. I will let you know if I get a response. If you want to direct comments to him you can e-mail him from his site at http://www.hypericum.com Thanks for pointing out these questions. I am really new at learning to read with a critical eye. I learn so much each day from all of you. Jodi Smart RN, IBCLC Port St. Lucie FL.
