The Efficacy and Tolerability of Turmeric and Salicylic Acid in Psoriasis Treatment.

Introduction: This study examined the efficacy and tolerability of a once-daily regimen of a 3% salicylic acid treatment gel containing turmeric and a low concentration of salicylic acid plus shea butter exfoliating moisturizer when used as monotherapy or in as an adjunct to other Rx psoriasis medications. Patients and Methods: This single-site 12-week study enrolled 20 subjects >18 years of age with mild-to-moderate psoriasis involving <10% body surface area. Assessments were performed at baseline and Weeks 4, 8, and 12 using a 5-point scale (0 = none to 4 = severe). The investigator-assessed efficacy (changes from baseline for erythema, desquamation, induration, and overall global assessment [IGA]) and tolerability (irritation and edema). Study subjects assessed efficacy parameters of redness, scaling, and overall skin problems along with tolerability parameters of stinging, burning, itching, and irritation. Subjects applied the turmeric and salicylic acid treatment gel along with a moisturizer once daily to all affected areas. Results: Half (50%) of the subjects were using concomitant Rx psoriasis treatments, while the other 50% received the study psoriasis treatment regimen as monotherapy. Investigator assessments of erythema, desquamation, induration, and IGA scores showed significant reductions from baseline ( Conclusion: A once-daily over-the-counter (OTC) turmeric/salicylic acid gel followed by a shea butter/salicylic acid exfoliating moisturizer demonstrated excellent tolerability and efficacy in plaque-type psoriasis after 12 weeks of once-daily use.
