Homeopathy and Science
This week’s entry† is a summary of some of the tests of homeopathy. It is a necessary prelude to a discussion of how homeopaths and their apologists promote the method. Several tenets of homeopathy lend themselves to tests. The doctrine of similia similibus curantur (“like cures like”) was tested by Hahnemann himself, as introduced in Part I of this blog. It is a special case that will be discussed further below. Hahnemann’s second doctrine, “infinitesimals,” suggests laboratory, animal, and clinical studies looking for specific effects of homeopathic preparations.
“Provings,” also called “homeopathic pathogenic trials,” suggest testing “provers” for the ability to distinguish between homeopathic preparations and placebos, and suggest asking homeopaths to identify specific remedies solely by the “symptoms” they elicit in “provers.” The homeopathic interview and prescribing scheme, gathering copious “symptoms” and matching them to the appropriate “remedy” in the Materia Medica, suggests testing homeopaths for consistency in symptom interpretations and prescriptions. The clinical practice suggests outcome studies, both of individual “conditions” (with the caveat that, strictly speaking, homeopathy does not recognize disease categories—only “symptom” complexes) and of the practice as a whole.
Several of these categories overlap. Several have been tested: the results have overwhelmingly failed to confirm homeopathy’s claims. I will mention a few of the more conspicuous examples.
