The second edition is designed to present most of the old information plus new information on the more important of those original 365 herbs.
With this edition, I have tried to cover most of the widely mentioned medicinal plants, 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.
