First published in French in 1911, this practical guide to the art of spagyrics begins by outlining the ancient yet often forgotten Hermetic foundations of herbalism. Author Jean Mav?ric provides botanical and medicinal classifications of over 600 plant species along with an in-depth study of their astral natures, elemental qualities, and planetary and zodiacal signatures as well as practical advice on the appropriate times to harvest plants and administer herbal remedies and quintessence's. Reviewing the general principles and procedures of premodern chemistry, Mav?ric then explores the secret doctrines and operations of the spagyric art. He offers a large collection of recipes for spagyric herbal preparations adapted from celebrated spagyrists such as Paracelsus, Pseudo-Lull, Philipp Ulstad, Jan Baptist van Helmont, Oswald Croll, and Nicaise Le F?vre, providing detailed step-by-step instructions for a veritable pharmacopeia of spagyric extracts, tinctures, elixirs, liquors, oils, unguents, salts, aquae vitae, and quintessence's. Mav?ric also shares his intricate theory of astral medicine and advocates a seasonal ?Hermetic diet? designed to keep the humors of the body in equilibrium and prevent the onset of illness. In the final section of the book, Mav?ric focuses on the more advanced methods and techniques of Paracelsus, Helmont, and George Starkey, unraveling the mysteries of manufacturing alkalis, alkahests, and menstrua and divulging his own secret formula for a universal circulatum. 6 x 9 paperback book with 256 pages.
