The Materia Medica in my website is being made with the help of different Homeopathic Books and research and also Homeopathy facebook groups, Homeopathic linkedin groups, and google Homeopathy Groups.
Some of the books I find excellent and use in my studies are:
Homeopathic Materia Medica & Repertory (William Boericke)
Homeopathic Clinical Repertory (Third Edition) By Robin Murphy.
Boericke’s New Manual of Homeopathic Materia Medica with repertory.
I am only one person working on this website… so with time it will be more complete. I do what i can for the Homeopathic World and to those who choose to go into homeopathy.
