Background: Hypertension is a prevalent cardiovascular risk factor, contributing to various debilitating conditions. Although pharmacological interventions are available, the side effects of medications negatively affect individuals’ adherence and quality of life. Plants from the genus Rhus, also known as sumac, have been traditionally used to treat cardiovascular and gastrointestinal diseases. Purpose: This narrative review aimed to assess the efficacy of sumac in blood pressure management through a comprehensive review of available clinical and pre-clinical trials. Methods: A systemic search of databases Medline, Excerpta Medica dataBASE and Cumulative Index to Nursing and Allied Health Literature was conducted up to March 2024. Results: Among 41 screened studies, five studies (four clinical and one pre-clinical) were included. All clinical trials demonstrated that sumac administration caused a significant reduction in systolic blood pressure (SBP). Sumac was effective in the reduction of diastolic blood pressure (DBP) in two studies. A pre-clinical study also showed a significant reduction in both SBP and DBP alongside increased nitric oxide expression. Conclusion: Sumac could have therapeutic and preventative effects on hypertension, potentially attributed to its antioxidant properties and ability to enhance nitric oxide production. However, further studies with longer duration and exploration of different sumac species are warranted to validate these findings and establish their therapeutic efficacy in blood pressure modulation. This review provides a foundation for future clinical investigations into sumac's role in hypertension management.
