Homoeoprophylyaxis has been part of mainstream homeopathy since 1798, but its use remains controversial. Its history and evidentiary base is frequently misunderstood. This book aims to provide homeopaths, as well as practitioners of any modality and students with a complete grounding in the topic. It contains comprehensive instructions on how to implement both short-term and long-term HP programs, a thorough presentation of the evidentiary base of HP as well as an in-depth discussion of its philosophical underpinnings. This is the most comprehensive resource currently available on the challenging topic of homeopathic immunisations.
