This book explores everything that is known about the manufacture of the mythical universal solvent of the alchemists. To do this, numerous procedures translated for the first time into Spanish, of incunabula books, have been explored, and experiments have been carried out until that special solvent has been achieved. It compiles the experience of many alchemists from different parts of the world.
The result is this checkered book of photographs explaining the processes and how to obtain not only the Alkahest, but also its most powerful the Universal Medicine. For the first time, the entire operation of Limojon de Saint Didier and its keys to philosophy are openly revealed.
