Of the estimated 7 million Americans diagnosed with psoriasis, about half will use complementary or alternative medicine therapies to treat their skin.
One of the more popular natural or alternative therapies lately has been turmeric, an Indian spice thought to have anti-inflammatory properties. However, according to ScienceDaily, support for using turmeric to cure psoriasis was dispelled by a prospective study published in the Journal of the American Academy of Dermatology.
The study, conducted at the University of Pennsylvania School of Medicine, found that the effect of curcumin (the active ingredient in turmeric) was so minimal on psoriasis that it could be attributed to a placebo effect rather than to any actual benefit of this natural therapy.
The authors concluded that oral turmeric (curcumin) should not be recommended for the treatment of psoriasis given lack of proven efficacy.
