Objective: To examine data from studies supporting the clinical efficacy of medical approaches from India traditional systems of medicines like Ayurveda, Unani, Siddha, and Homeopathy for psoriasis using outcome indicators employed in clinical practice and research. Methods: Searches were conducted between December 2019 and September 2020 in databases PubMed, Scopus, Web of Science and Ovid Medline using search terms including traditional, complementary, psoriasis, Kushtha, Ayurveda, Siddha, Unani, Homeopathy and clinical. Controlled trials, case series and case reports published from India were included. Results: Data of 17 selected studies were extracted. Treatment efficacy in terms of improvement in Psoriasis Area and Severity Index (PASI) score or/and percentage reduction in score (PASI 50, PASI 75 and PASI 90) or/and patient-reported outcomes using instruments like Dermatology Life Quality Index and Psoriasis Disability Index were noted. All studies reported good improvement as per the study specific outcome. However, study characteristics, including study design, sample size, follow-up period, inclusion and exclusion criteria were heterogeneous, and the choice of outcome measures was not adequate to conclude the effectiveness of intervention. The use of some herbs as common ingredients in several formulations across different systems of medicines were noted in analyzing individual formulation. Conclusions: Future studies must incorporate a comprehensive study design with specific outcome measures like PASI, PASI 75, PASI 90, quality of life parameters, compliance to medications, adverse reactions, remission period, relapse rate and cost-effectiveness with long term follow-up. The currently available evidence on the roles of these herbs at molecular level in psoriasis is preliminary.
