Abstract

Psoriasis has become a topic of global concern because of consistency in its prevalence according to Global Report on Psoriasis 2016, however, till date, no therapy has provided complete cure of this disease and no useful measure was discovered to prevent it or eliminate the risk of its relapse. Hence, the present study was designed to evaluate anti-psoriatic effects of Spinacia oleracea due to its anti-inflammatory, anti-oxidant, anti-proliferative and skinstrengthening contents. Psoriasis was induced by oral potassium iodide solution which was then determined by two methods i.e. percentage reduction in psoriatic patch size and psoriasis area and severity index (PASI) score to measure the decrease in severity. Twenty albino rats were used in each method, grouped as standard, curative, preventive and control with five rats in each group. Therapeutic and preventive doses for S. oleracea in both the methods were calculated according to daily intake guidelines of National Cancer Institute, USA, and German Nutrition Society, DGE guidelines respectively with slight modification. Methotrexate was used as standard drug along with folic acid to avoid toxic effects. This study reveals that S. oleracea has both therapeutic and preventive effects. It may be concluded that S. oleracea can be effectively used as sole therapy for psoriasis. Keywords: Psoriasis,
