The finest-quality manuka honey, with the most potent antimicrobial properties, is produced from hives in wild, uncultivated areas. Since 2004, Britain's National Health Service has licensed the use of manuka honey wound dressings and sterilised medical-grade manuka honey creams.
Manuka honey has an antibacterial component that sets it apart from other honeys. This activity is stable and doesn't lose its potency when exposed to dilution, heat or light. It has been found to be effective against a range of bacteria including Helicobacter pylori (which causes most stomach ulcers); Escherichia coli (the most common cause of infected wounds) and Streptococcus pyogenes (which causes sore throats).
