Medical News: Anecdotal evidence touting the healing power of the Indian spice turmeric for psoriasis received a setback in a prospective study published this month by a leading dermatology journal stating that the low response rate of patients who ingested the active ingredient of the exotic spice was probably a result of the placebo effect.
Researchers at the University of Pennsylvania School of Medicine found that despite strong scientific evidence in the laboratory demonstrating the ability of curcumin (the active ingredient in the spice turmeric) to inhibit a critical pathway of psoriasis, the positive response in patients was so low that scientists suggest the placebo effect or the disease's natural remission might be the reason. The study was published in the Journal of the American Academy of Dermatology.
