Hypnosis was used to alter body image in an attempt to enable a woman to retain a skin homograft from an unrelated male donor. The man also acted as a nonhypnotized control by receiving a homograft from the hypnotized woman. Oneinch square full-thickness skin homografts were exchanged between the upper arms of the two volunteers. The homograft on the arm of the woman is still viable after eight months; the homograft on the man was rejected within two weeks.
A significant portion of the traditional concepts of homeopathy (similia principle, experimentation on healthy humans, the cure of whole person, the use of minimum doses or high dilution/potency of medicines) are amenable to investigations conducted according to criteria accepted by biomedical science. Even though many randomized and controlled clinical studies seem to demonstrate the efficacy of some homeopathic medicines and their superiority to placebo, other trials have given negative results.
