Colin Griffith

Colin Griffith (MCH RSHom) is a British homeopath, teacher and author described as a highly respected practitioner of homoeopathy. He studied at the College of Homoeopathy in London from 1986 to 1989 and is a founder member of the Guild of Homoeopaths as well as a regular lecturer at the Centre for Homoeopathic Education.

In 1999, Griffith founded the Guild of Homoeopaths together with Janice Micallef and the late Martin Miles. Structured as a two-year postgraduate course, the Guild grew out of a meditation group dedicated to the research and meditative proving of new remedies. Through this meditative proving method, practitioners of the Guild have introduced a body of new crystal, botanical and animal remedies into homeopathic practice.

Griffith is best known for The New Materia Medica series, source books documenting these meditatively proved remedies. The first volume, The New Materia Medica: Key Remedies for the Future of Homoeopathy, was published by Watkins in 2007 and presents 30 new crystal, botanical and animal remedies. Volume 2 followed in 2011 with a further 30 remedies, and Volume III, drawing on ten years of testing by Griffith's group, was published by Watkins in 2023 with another 36 new remedies. He also compiled The Comprehensive Repertory of New Homoeopathic Remedies (2015), a 376-page repertory making these new remedies accessible for case analysis.

Beyond the new-remedy materia medica, Griffith has written practitioner-oriented works including The Practical Handbook of Homeopathy and The Companion to Homeopathy: The Practitioner's Guide. His most recent published work in the series, The New Materia Medica Volume III, appeared in 2023.
