A book about herbs and plants, especially those which possess medicinal and healing properties (based on scientific evidence) or those whose medicinal values are based entirely or in part on conjecture or folklore. One of the most interesting and popular herbals of all time is Nicholas Culpepper's astrologically influenced herbal guidebook entitled The English Physician (also called The Complete Herbal). It was originally published in the mid-seventeenth century and remains popular in modern times, especially among Witches and students of herbalism and plant lore.
