The strongest evidence supports its role in wound care: treating diabetic ulcers, burns and slow-healing post-surgical sites. “Medical-grade manuka honey has been shown to reduce bacterial load, support tissue regeneration and, in some cases, accelerate healing compared with conventional dressings,” says GP and functional medicine specialist Dr Nirusha Kumaran. Research also suggests it can inhibit antibiotic-resistant bacteria, including MRSA, through a combination of high sugar content, low pH and bioactive compounds such as MGO, says nutritionist Lucy Miller. Dr Kumaran notes it may help soothe sore throats and reduce coughing.
