AIH Guide to Homeopathic Research

Those of us within the homeopathic medicine community often hear the criticism that there is no research in support of homeopathic medicine.  There are in fact thousands of homeopathic research studies.  The following studies have been selected to demonstrate the different types of homeopathic research and some of the important research findings in support of homeopathic medicine.


Methodological Issues for Homeopathic Clinical Research

Homeopathic research, and the criticisms of homeopathic research, cannot be understood if the philosophical assumptions of homeopathic medicine are not understood.  These philosophical assumptions necessitate a different set of criteria for assessing the validity of homeopathic research.  In the following article, the authors recommend a method for assessing the model validity of homeopathic RCTs that is consistent with the basic tenets of homeopathic medicine.

RCTs using Individualized Homeopathic Medicines

Homeopathic medicines treat persons, not diseases -- that is, the prescription for an individual with a disease is based on the expression of the disease in that particular person, rather than on the disease diagnosis per se.  Thus, not every person in an RCT will receive the same homeopathic medicine.  This principle of homeopathic medicine increases the complexity of any RCT on the efficacy of homeopathic medicines.  The following studies were designed with respect for homeopathic principles and yielded statistically significant positive results.

Longitudinal Research

Use of Homeopathic Medicines for Prophylaxis

Homeopathic medicines can also be used as prophylactic treatment against epidemic diseases.

Effects of Homeopathic Medicines vs Placebos

Despite the findings of statistically significant positive results in well-controlled studies, some critics of homeopathic medicine assert that positive findings are due to a placebo effect.  The following study demonstrates that effects of homeopathic medicines differ from the effects of placebos. 


Veterinary Homeopathic Research

Further evidence that the positive findings in homeopathic research are not due to the placebo effect is that veterinary homeopathic research also yields statistically significant clinical results.  Several important studies are:



Research on the homeopathic treatment of diseased plants also yields statistically significant results, emphasizing again that it is unlikely that the positive results of homeopathic treatment are due to the placebo effect.
