However, that doesn’t mean you should go guzzling honey from the supermarket just yet. Butler says that consumer honey doesn’t contain these bug-battling bacteria, as it has usually been sterilized to eliminate spores and other elements that could cause health problems. Additionally, as honey crystalizes with age, it loses much of its water content, causing these crucial bacteria to die off. So, in order to make their medicinal salves, Butler and her research team reintroduced the good bacteria into honey that had already been sterilized. They then let the bacteria grow for 24 to 48 hours, allowing the microorganisms to produce a multitude of antimicrobial substances. They think that these antimicrobial compounds are what destroy antibiotic-resistant germs.
