Homoepathic physician must study the homoeopathic principles till he learns, what it is in sickness that guide to the curative remedy ( oragnon and homoeopathic philosophy / grammer ) he must study the materia medica until he learns, what is need to meet this demands ( Materia Medica / Literature ). He must then study the repertory until he lerans how to use it, so he can find what he wants, when he needs it ( repertory / Dictionary )

No one can know everything and that is why all honesty, one must admit that in conscientious homoeopathic doctor can practice homoeopathy in a serious and really scientific way without repertory.

In the department of repertory we have various charts and various software for learning the different repertories.
