With this edition, I have tried to cover most of the widely mentioned medicinal herbs, whether they are extremely salubrious or extremely toxic. Without counting them, I estimate we include more than 1000 of the most important herbs, including the more important herbs from the young Native American and the European traditions (including most of those approved by Commission E (KOM), and almost all of those included in the PDR for Herbal Medicine (PHR for the first edition, and PH2 for the second edition). Unlike Commission E and the Herbal PDR, which seem to stress European and American traditions, I include proportionately more herbs from the older African, Ayurvedic, and Chinese traditions as well, not wanting to slight any major medicinal plant from any major tradition. All science books are built on what has gone before, hopefully seizing the best and discarding the worst. It’s not plagiarism if one cites one’s sources. I am deeply indebted to all those scientific writers with and before me, who have written about phytochemicals and phytopharmacy; and to our ancestors before them, who sampled the plants around them, and learned which were edible, medicinal, and poisonous, and who lived to talk about it. Also let me acknowledge you, my readers, for struggling with this, my most ponderous,yet I hope most useful, book. If you like it and find any errors, let me know. I hope to keep it updated on my computer at home. Then maybe Barbara and CRC Press, maybe even you, will be ready for a third edition. New scientific data is pouring in, hopefully proving me right, that herbal phytochemicals are cheaper and safer
