Introduction
In a 2007 research review1 entitled The Evidence: Scientific Studies on Homeopathic Cancer Treatment published in The American Homeopath we concluded:
“homeopathic drugs have proven biological action in cancer; in vitro and in vivo; in animals and humans; in the lower, as well as in the higher potencies. Cancer patients are faced with a life-and-death decision when choosing their treatment. Since most conventional treatments continue to be associated with severe adverse and sometimes fatal effects, while homeopathy has been found to be free from such effects, it would seem plausible and worthwhile, even urgent, to step up the research on, and even the provision of, homeopathic treatment of cancer and other diseases.”
For the present paper we have reviewed articles on homeopathic cancer treatment published during the last five years in peer-reviewed scientific journals.
Homeopathic cancer treatment has great promise, given the exceptional safety of the treatment and the relatively frequent observation of beneficial clinical effects.2 However, in our last review we had noted a remarkable confusion among researchers on key concepts in homeopathy and we attributed this to editorial control. We also commented on the fact that virtually all studies of homeopathic cancer treatment are in reality investigating the effects of high potency drugs, not the efficacy of homeopathic treatment. This should be kept in mind when reading the present review.
