The discipline of Occult Herbalism encompasses the knowledge and use of the magical, spiritual, and folkloric dimensions of plants. This perennial wisdom animates many global spiritual traditions, especially those which have maintained their integrity of transmission even in the face of industrial development and cultural destruction. Often concealed within the deepest strata of the Western Esoteric Traditions, this green strand of wisdom is a potent legacy of all magic, sorcery, and occult science. In addition to the hard sciences of botany, ethnology, agriculture and ethnopharmacology, a number of pathways can assist the magical herbalist in furthering the depth of understanding and integrity of personal approach. 'Thirteen Pathways of Occult Herbalism' circumscribes the metaparadigm of herbal magical practice, providing useful examples of its manifestation, as well as demonstrating its time-honored routes of inquiry.
