Patients with psoriasis found to use complementary or alternative medicine regularly to treat their symptoms, according to a survey of George Washington University (GW) published in the Journal of the American Academy of Dermatology.
According to the Centers for Disease Control and Prevention, psoriasis is chronic autoinflammatory skin disease that speeds up the growth cycle of skin cells, which causes raised, red, scaly patches to appear on the skin.
Treatments for psoriasis range from topical ointments to ultraviolet light therapy to drugs. Psoriasis is associated with other serious conditions, such as diabetes, heart disease, and depression.
"Patients turn to these treatments because what was initially prescribed is not working out for them," explained Friedman. "But what we found through the survey is that patients may not completely understand what products will work best for them."
The survey found that patients reported using complementary and alternative medicine that have not previously exhibited efficacy or have not been studied for the treatment of psoriasis. Vitamins D and B12 were frequently reported, though neither of which have documented efficacy against the disease.
In contrast, indigo naturalis -- a plant extract widely used in Traditional Chinese Medicine and recognized as a therapy for several inflammatory conditions -- has shown efficacy, but was not reported in the survey. Dead Sea treatments were commonly reported and have shown therapeutic benefit.
"In addition to the chosen treatments, we also found that less than half of the respondents would recommend complementary or alternative therapies to others," Friedman said. "This could be a result of using therapies supported by limited evidence."
Acknowledging that these treatments are part of patients' armament, Friedman and his team suggest that educational initiatives that enable physicians to discuss evidence-based complementary and alternative medicine may improve patient satisfaction and outcomes.
