‘Researchers at Cardiff Metropolitan University have found that manuka honey is effective in combating the bacteria Streptococcus Pyogenes, which can make wounds hard to treat. This condition has worsened because of resistance to antibiotics; however, it seems that the manuka honey can actually penetrate that resistance and kill the bacteria, even in small concentrations.
Other benefits include no instances of honey-resistant bacteria, plus honey is more cost-effective than antibiotics and may also complement antibiotic treatment. If you want to use manuka honey for wound care, it is recommended that you use a medical grade product that has been treated to kill any bacteria on it’.
