Glossary
A substance that kills or inhibits the growth of microorganisms including bacteria, fungi, viruses, or parasites. Honey and propolis are naturally antimicrobial through multiple mechanisms: low pH, high osmolality, hydrogen peroxide production, and specific bioactive compounds.
What makes honey and propolis exceptional antimicrobials is that they attack pathogens through multiple simultaneous mechanisms. A bacterium can evolve resistance to a single antibiotic compound relatively quickly, but overcoming multiple different antimicrobial mechanisms simultaneously is exponentially more difficult. This is why honey has remained effective as a wound treatment for thousands of years while synthetic antibiotics face growing resistance challenges.
Osmolality: Honey's extremely high sugar concentration (approximately 80%) creates an osmotic environment that draws water out of bacterial cells, dehydrating and killing them. Acidity: Honey's pH of 3.2 to 4.5 is below the optimum growth range for most pathogenic bacteria. Hydrogen peroxide: The enzyme glucose oxidase (added by bees during processing) produces hydrogen peroxide when honey is diluted with wound fluid or water, creating a sustained, low-level antiseptic effect. Bee defensin-1: A peptide produced by bees' immune systems and found in honey, active against gram-positive bacteria including MRSA. Methylglyoxal: Specific to Manuka honey, providing non-peroxide antibacterial activity.
Propolis derives its antimicrobial power from a different set of compounds. Flavonoids (pinocembrin, galangin, chrysin) and phenolic acids (caffeic acid, ferulic acid) disrupt bacterial cell membranes, inhibit protein synthesis, and interfere with bacterial enzymes. Like honey, propolis works through multiple mechanisms simultaneously, making it effective against resistant organisms.
Yes. Research has demonstrated that certain honeys, particularly Manuka, are effective against methicillin-resistant Staphylococcus aureus (MRSA) and other antibiotic-resistant strains. The multiple simultaneous antimicrobial mechanisms make it very difficult for bacteria to develop resistance.
Raw honey has documented antimicrobial properties, and medical-grade honey is used in clinical wound care. However, honey should not replace prescribed antibiotics for systemic infections. It is most appropriate for topical applications (wound care, sore throat) and as a complement to, not a replacement for, conventional medical treatment.
