Bees knees。Honey is making a comeback as a wound care product. The use of honey for medicinal purposes dates back to Egyptian times when it was used both topically and internally to treat a wide range of health problems ranging from skin infection to gaping wounds and stomach ulcers. However, modern civilisations have regarded honey more as foodstuff than as medicine. Today, medical-grade manuka honey from New Zealand is healing wounds where more conventional treatments have failed. It can be used on partial or full thickness wounds including pressure sores, leg ulcers, surgical wounds, burns and graft sites. The honey is applied directly to the wound bed followed by an occlusive dressing, or as top-up to a honey-impregnated wound dressing.Honey is able to clean wounds because the high sugar content provides an osmotic potential that draws moisture into the skin. Moisture management is a key feature of wound healing; the benefits of maintaining a warm, moist environment are widely accepted. Infection control is fundamental to wound care, and the high acidity or low pH of honey makes it bactericidal. Consequently, honey may be able to control wound infection where antibiotics have failed. Honey has anti-inflammatory properties and it reduces wound exudate, which if not contained can macerate the surrounding skin to increase the risk of infection.Honey treatments are generally well received by patients, who view them as a natural cure, although body temperature makes honey very runny, creating a sticky mess that may require more frequent dressing changes. The only contraindication to using honey is a known allergy to bee venom. Some patients may experience an increase in pain due to its osmotic action. Whilst eating honey is not an option for patients with diabetes, there are no reports of topical honey increasing blood glucose levels, though the manufacturers advise that these levels are closely monitored.
