                                According to scientific studies, the antibacterial activity of most honeys is caused by hydrogen peroxide, but some honeys, most notably Manuka, contain high levels of methylglyoxal (MGO), which is responsible for its potent non-peroxide activity. This guide explores which specific honeys contain methylglyoxal, where it comes from, and how its concentration varies.
