MANUKA Fill is a medical-grade wound care dressing for all types of wounds. Manuka Fill is CMH certified and contains filtered, sterilised manuka honey from New Zealand. Manuka honey is increasingly being used in health care for dressing wounds, as it inhibits bacterial growth and has an anti-inflammatory effect. Manuka Fill cleans wounds with an osmotic effect and creates a low pH which inhibits bacteria, while creating a moist wound environment conducive to healing. Manuka honey has a long history, and is used throughout the Western world due to its notable and enduring properties. The nectar used to produce the honey comes from the manuka flower. What makes manuka honey so special is that it contains methylglyoxal (MGO), a bioactive substance which is considered to bacteria from attaching to cells.
