evidence: Hydrogen peroxide gives most honey its antibiotic quality. But some types, including Manuka honey, also have unique antimicrobial qualities. One of the major antibacterial components of Manuka honey is a compound called methylglyoxal (MGO). MGO comes from the conversion of another compound in Manuka honey known as dihydroxyacetone (DHA), a high concentration of which is found in the nectar of Manuka flowers. [...] Another possible benefit of honey is that, unlike antibiotics, it doesn’t appear to lead to resistant bacteria. These so-called "superbugs" develop after repeated exposure to common antibiotics. Special antibiotics are needed to treat them.
