The study investigates the health benefits of propolis in humans, focusing on its effects on oxidative stress and lipid levels, since most prior research was done on animals.
A double-blind, placebo-controlled trial involved 67 participants divided into propolis and placebo groups, with evaluations at baseline, 45, and 90 days.
Results showed significant increases in HDL cholesterol and levels of antioxidants in the propolis group, suggesting that propolis may help reduce the risk of cardiovascular disease.
