Scientists Identify a Secret Ingredient in Honey That Kills Bacteria

New information has been uncovered for those looking for a natural alternative to antibiotics. Research published in the July 2010 print edition of the FASEB Journal explains for the first time how honey kills bacteria. The research shows that bees make a protein that they add to the honey called defensin-1, which can be used to treat burns and skin infections.

"We have completely elucidated the molecular basis of the antibacterial activity of medical-grade honey, which contributes to the applicability of honey in medicine," said Sebastian A.J. Zaat, Ph.D., a researcher involved in the work from the Department of Medical Microbiology at the Academic Medical Center in Amsterdam. "Honey or isolated honey-derived components might be of great value for prevention and treatment of infections caused by antibiotic-resistant bacteria."

To make the discovery, Zaat and colleagues investigated the antibacterial activity of medical-grade honey in test tubes against a panel of antibiotic-resistant, disease-causing bacteria. They developed a method to selectively neutralize the known antibacterial factors in honey and determine their individual antibacterial contributions. Ultimately, researchers isolated the defensin-1 protein, which is part of the honeybee immune system and is added by bees to honey. After analysis, the scientists concluded that the vast majority of honey's antibacterial properties come from that protein. This information also sheds light on the inner workings of honey bee immune systems, which may one day help breeders create healthier honey bees.

"We've known for many years that honey can be good for what ails us, but we haven't known how or why it works," said Gerald Weissmann, M.D., Editor-in-Chief of the FASEB Journal, "Now that we've extracted a potent antibacterial ingredient from honey, we can make it still more effective and take the sting out of bacterial infections."

Even though all types of honey contain healing properties to some degree, it has been determined that Manuka honey from New Zealand seems to have the highest levels of these healing properties. Therefore, active medical-grade Manuka Honey is most appropriate for medicinal use.
