(Rhus) has been investigated in multiple animal stud- ies with promising results. Nonetheless, its clinical efficacy has not been adequately examined. Objective: The aim of this study was to evaluate the lipid-lowering effects of Rhus among patients with hyperlipidemia. Design, setting, participants and interventions: The study was designed as a two-arm, double-blind placebo-controlled randomized clinical trial, using a parallel design. Eighty patients with primary hyper- lipidemia were randomly assigned to receive Rhus capsules or placebo for 6 weeks. Main outcome measures: The serum lipid levels, apolipoprotein-A1 (Apo-A1) and apolipoprotein-B (Apo-B) were measured. Results: Mean serum high-density lipoprotein cholesterol (HDL-C) and Apo-Al levels were significantly increased in the Rhus group, compared with the placebo group, after 6 weeks of intervention (P= 0.001). The analysis of covariance test including age, gender, body mass index (BMI), and smoking as co-variables revealed that the increase in HDL-C and Apo-A1 levels remained significant, and increases in HDL-C were dependent on the increase in Apo-A1 levels. No significant difference was observed between Rhus and placebo groups in terms of mean reductions in total cholesterol, low-density lipopro- tein cholesterol and triglyceride levels; however, more significant improvement was observed among obese patients (BMI≥ 30 kg/m^2). Conclusion: The study showed significant increases in HDL-C and Apo-Al levels in response to Rhus sup- plementation in patients with hyperlipidemia.
