This books strives to make us aware again of the relation between human beings and medicinal plants. Not a book that tells us how to prepare and use different plants for therapy, but instead one that develops paths for insights into the healing powers of plants. Insights not based only on ancient traditions or ethnobotanical discoveries, but on enhanced capacities of perception. These perceptions focus not merely on the morphology of plants in the Goethean sense, but in addition take full cognizance of phytochemistry. Through the many illustrations and woodcuts by the late Walther Roggenkamp, one can gain an image of what nature has withheld and words do not express; aspects of the plant’s essence emerge, made visible through the artist’s creations.
