The medicinal power of honey is well documented – it’s antibacterial, so has been used in treating wounds. In dressings, it helps clean pus or dead tissue, suppresses inflammation, and promotes new skin growth. A 2007 study at Penn State suggests that it is more effective than dextromethorphan in treating a cough. Irish labs have shown that it combats MRSA infections. Manuka honey kills the bacteria that cause ulcers and is used to preserve corneas for transplants.
