Psoriasis is a chronic disease that has no definitive cure. In this review study, the main sources of Persian Medicine (PM) such as the Canon of Medicine (by Avicenna) and
Al-Havi
(by Rhazes) were assessed to identify non-pharmacological treatments for psoriasis. Several treatments that are recommended for this disease include nutritional advice, lifestyle modifications, and manipulation therapy such as wet cupping (
Hijamah
), leech therapy, and phlebotomy (
Fasd
). These recommendations may help to prevent recurrence and be useful in improving psoriasis. The efficacy of PM recommendations to improve psoriasis should be evaluated in future studies.
