Physical cosmologists and physicists are now in search of a so called ―Unified Theory‖ of the Universe; without a consideration of the first principle of healing intention, or Prima Materia Medica, the search may continue in vein. Iatrochemistry or Medical Alchemy offers a holistic or ecological theory of evolution and cosmology that seeks Quintessence of both spirit and matter. This presentation will include discussions on the history, theory, and practical aspects of traditional laboratory alchemy as well as an exploration for a new, yet traditional, theory of evolution. Spagyria Medica technology and herbal preparations will be covered along with historical contributions from past Adepts. This presentation will focus on the transmutation of living medicines and Nature as the guiding compass towards a harmonized health process. Insights will be shared regarding the culture, science, and art of immortality.
