Frans Vermeulen is one of the great scholars and researchers in homeopathy. Author of many books, he has helped classify and arrange vast amounts of information on homeopathic materia medica and his research into the origin of substances has greatly enhanced our knowledge of homeopathic medicines.
In 1990 he was appointed managing director, teacher, and administrator of 'The School of Homeopathy' in Holland. In 1992 he wrote 'Synoptic Materia Medica 1' which originally emerged from remedy summaries made for the students in Holland, Ireland and Finland.
He followed this one up with the 'Concordant Materia Medica' published in 1994. Followed by a second edition of the Concordant, including Hering's Guiding Symptoms in 1997; a third edition was printed in 2000.
Out of his special interest in the small remedies, Frans wrote 'Synoptic Materia Medica 2'. In the completely revised edition of Synoptic 1, entitled 'Prisma', he introduces us to data from numerous non-homoeopathic sources as both reference material for the homoeopathic materia medica and as the source of potential symptoms. The significance and potential of such external data has been the subject of his numerous seminars in Europe, Israel and Australia.
