Pooling 20 randomised trials in 2,445 adults with metabolic syndrome or related conditions, supplements from the mint and sage family produced modest reductions in BMI, weight, waist circumference and waist-to-hip ratio. Directly measured body fat mass did not change significantly.
What it shows: Meta-analysis of 20 RCTs (n=2,445) in adults with metabolic syndrome, obesity, type 2 diabetes, dyslipidaemia or fatty liver; half the trials had unclear allocation concealment, 10% had high performance bias risk, trials were short, body fat was measured indirectly, and the genus-level signals for Salvia and Zataria came from few trials.Review · J Ethnopharmacol
