According to Vithoulkas's citation from the Right Livelihood award, his books "have had a profound influence upon the acceptance and practice of homeopathy worldwide." Lyle Morgan says he is "widely considered to be the greatest living homeopathic theorist"; and Scott Shannon calls him a "contemporary master of homeopathy."
Paul Ekins credited Vithoulkas with the revival of the credibility of homeopathy. Vithoulkas has also made an expert system 'VES'(Vithoulkas Expert System) that has been incorporated into the RADAR software. His biography has been published in the book
Georgos Vithoulkas Der Meister-Homöopath Biographie und Fälle by the journalist Peter Clotten and the homeopath Susan Pfeifer who studied at his International Academy for Classical Homeopathy. In 1978,
Anthony Campbell, then a consultant physician at The
Royal London Homeopathic Hospital, reviewed
The Science of Homoeopathy. He criticised Vithoulkas for substituting assertion for hard evidence and constructing an almost meaningless argument on the basis of a dubious theory of disease. He described rhetoric put forward by Vithoulkas (in presenting the argument that "allopathic drugging" is harmful and must be avoided) as including a thoroughly irresponsible statement which could mislead an unfortunate layman into refusing orthodox treatment, mentioning Vithoulkas' claim, "in the course of an argument designed to show that 'allopathic drugging' is harmful and must be avoided", that
syphilis, when treated with antibiotics, would have the early stages suppressed, but would go on to the secondary and tertiary stages. However, he felt the book also provided a good, if dogmatic, description of the principles and practice of "classical" homoeopathy. In response, Vithoulkas quoted various medical studies he claimed supported his assertion that
penicillin "may suppress primary syphilis while failing to prevent the insidious development of a tertiary stage, especially as manifested in psychosis." Vithoulkas's claims conflict with scientific studies, which indicate that penicillin treatment produces a complete cure of syphilis in more than 90% of cases. ==Selected works==
