Summary:
- Researchers discovered that increasing the UMF (Unique Manuka Factor) rating of Manuka honey significantly enhances its antibacterial efficacy against MRSA (methicillin-resistant *Staphylococcus aureus*).
- Higher UMF concentrations (UMF 20 compared to UMF 5) allowed for a drastic reduction in the honey concentration required to inhibit 95% of MRSA growth, dropping from 15% to 3%, suggesting potential therapeutic applications for wound care.
