The book spans a range from Stone Age culture through medieval alchemists to the traditional medical systems of Europe, China, and India. It discusses misunderstood gold-making techniques, the Philosopher's Stone, the language of the Yaghan, Hippocrates, Agricola, and Druids, as well as pulse diagnosis, fire arts, the modernity of inner alchemy, planetary forces, outlines of simple plant preparations, and the principles of mercury, salt, and sulfur. The spagyric essence, the fixation of mercury, and the preparation of amber and coral through distillation are also presented. A book for anyone interested in natural healing.
