Effect of sumac powder on clinical symptoms, hyperandrogenism, inflammation, blood glucose, lipid profiles in women with polycystic ovary syndrome: A double-blind randomized clinical trial.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders associated with a high risk of diabetes, atherosclerosis, and cardiovascular disease. The purpose of this study was to determine the effect of sumac powder on clinical symptoms and laboratory parameters in women with PCOS. The double-blind randomized controlled clinical trial was conducted on 88 women with PCOS randomly assigned to the intervention and control groups. The intervention group received three capsules each containing 1 g of sumac powder for 12 weeks. All data and serum levels of sex hormone, hs-CRP, glucose, and lipid profiles were measured at the baseline and at the end of the study. Data were analyzed using SPSS version 25 software. The ANCOVA test results showed that hs-CRP level was significantly reduced in the intervention group (p = .008). Blood glucose and lipid profiles in the intervention group were significantly reduced compared to the placebo group (p < .05). Insulin sensitivity and HDL levels were increased significantly in the Sumac group after the intervention (p < .05). Sumac powder can reduce the inflammatory effects, and glycemic status and lipid profile of polycystic ovaries in affected women, but has no significant effect on anthropometric parameters and sex hormones.
