The second edition is designed to present most of the old information plus new information on the more important of those original 365 herbs. I submitted the first edition under the original unpublished title, Herbs of Dubious Salubrity. I intentionally left out many of the completely safe culinary herbs, spices, and food plants that are clearly medicinal. I also intentionally omitted some strictly dangerous herbs, such as foxglove, that were too unhealthy for use in unskilled hands. I did include several obscure hallucinogenic plants of dubious salubrity. I did, or should have, dropped some of these because they have little medicinal importance. Some poorly documented species, such as Mimosa hostilis and Phoradendron leucarpum, for example, were retained with fragmentary entries, so as to at least mention species from the first edition that might better have been dropped.
