Beneficial effect of Nigella sativa supplementation on non-alcoholic fatty liver disease.
The aim of this randomized, double-blind and placebo-controlled trial was to investigate the efficacy and safety of Nigella sativa seed oil in the treatment of patients with non-alcoholic fatty liver disease (NAFLD).
To do so, 120 patients with non-alcoholic fatty liver disease were randomized to receive either 2.5 mL of a fully standardized N. sativa seed oil every 12 h or a placebo for 3 months.
Results showed that grade of hepatic steatosis was significantly reduces in the oil group compared to the placebo (p = 0.004). Moreover, triglycerides, LDL-C and HDL-C were significantly decreased compared to placebo (p = 0.001, p = 0.01, p = 0.001 respectively). However, the oil did not significantly affect the other outcome variables compared to the placebo (all p > 0.05).
Authors concluded that Nigella sativa seed oil seems to be safe and improve liver disorders in the NAFLD patients.
