The first edition of James Tyler Kent's Lectures on Homoeopathic Materia Medica was published in 1905. Kent felt that "the speech of laymen presents all sickness to the physician's mind, hence the Materia Medica must be reduced from technicalities to simple speech. By presenting every remedy's strong characteristics Kent shows how the Materia Medica is evolved and used. This is one of the first instances where a remedy picture is portrayed. Here are 217 remedies from the pen of one of the most influential American homeopaths. These are the transcribed lectures from Kent's classes at the Post-Graduate School of Homoeopathy in Philadelphia. Though not a primary Materia Medica, there are wonderful gems to be found within. Witness the distinctive picture of the sycotic miasm within the context of the remedy, Natrum sulphuricum. The colloquial presentation leads to an easier grasp of the information. The lectures are in simple form, explaining Kent's plan of study for each remedy.
