Abstract
BACKGROUND: Psoriasis vulgaris poses health challenges to humans. Despite notable progress in the understanding of disease pathogenesis and the availability of various treatment options, a definitive cure remains elusive. Given the various side effects and high treatment costs, many patients seek natural remedies. This study aimed to assess the effectiveness of novel topical flaxseed oil in individuals with mild to moderate plaque psoriasis. MATERIALS AND METHODS: The outcomes of topical flaxseed oil were compared with those of betamethasone ointment in a two-arm parallel, randomized, controlled clinical trial involving 60 patients. The participants applied the medication as a thin layer to the skin lesions, massaging it twice a day for 4 weeks. Before and after the intervention, they were assessed using two standard questionnaires: the Psoriasis Area Severity Index (PASI) and the Dermatology Life Quality Index. RESULTS: Statistical analysis showed that, after 4 weeks, flaxseed oil significantly decreased the PASI score (2.43 ± 1.83 vs. 5.85 ± 5.08, P: 0.001) and enhanced the quality of life of patients (3.47 ± 3.16 vs. 8.48 ± 5.53, P = 0.001) in comparison to betamethasone ointment. Notably, no side effects were observed in the flaxseed oil group. CONCLUSION: The outcomes suggest that topical flaxseed oil can be an effective complementary therapy for psoriasis vulgaris.
