About the author

Frans Vermeulen

Born in 1948 in Den Helder, Netherlands, Frans Vermeulen trained as a homeopath in The Hague and opened his practice in 1979 after working as a primary school teacher. He has translated major works by Kent, Allen, Tyler and Vithoulkas, and authored a series of materia medica references — from Synoptic Materia Medica I (1992) and Concordant Materia Medica (1994) through the Ultimate Prisma Collection — that are among the most widely used in contemporary homeopathic practice.
