And here we should keep in mind that "successful" in holistic medicine (not only homeopathy) is defined/understood in a very different way than in so-called conventional medicine - so I'm not sure that everyone would be able to agree that the swan is black unless people start to think (I'm sorry to repeat myself) about people in the first place, and the oath of Hippocrates which states "no harm" first.

And what about ethics re the details of homeopathic treatment that I've mentioned?

Also do you suggest that "successful" treatment exists in every possible condition? I have often read re cancer treatments, for example, that "the operation was successful, but the cancer spread to other organs and patient succumbed to this shortly afterwards". Now, what should "successful operation" mean here in the first place? Clearly the span of trials and assessment of treatments should be extended - and the quality of life somehow included in the aspects to be assessed (in allopathy) - then it will become clear which treatment regime is (I will not say successful) beneficial to the patient. Homeopathy, for one, always thinks in terms of the whole time-line of the person's life-long existence... And I have also read about complete recovery from (adult) leukemia - only on a Russian homeopathic site
