The Temper of Herbs


By Robert Allen Bartlett

150 pages / 30 Oct 2020 

In this landmark exploration of the qualities of elemental degree, Robert Allen Bartlett sets up ancient alchemical natural philosophy against modern lab equipment. In the span of 150 pages, he outlines the historical basis for assigning temperament to an herb, and then presents raw laboratory data, in some cases copied facsimile from his own notes, to probe how chemistry either confirms or denies the results achieved through traditional alchemical theory and medical practice.

The first printing, limited to 666 copies, features a full color interior and gold foil cover accents.
