Manuka Honey's Antibacterial Power Goes Beyond Sugar and MGO

New research from Aston University shows Manuka honey's antibacterial effects against respiratory pathogens, including drug-resistant MRSA, stem from a combination of sugar, methylglyoxal (MGO), and other compounds. Higher UMF grades correlated with stronger activity, outperforming sugar or MGO alone. The findings, published in Microbiology, highlight potential new approaches to antimicrobial resistance.
