Manuka honey is often called a natural healing wonder—and not without reason. Unlike regular honey, it shows exceptionally strong antibacterial effects driven by its natural compound methylglyoxal (MGO). From infections and wound care to soothing inflamed mucosa and supporting immunity—its uses are diverse. Heres what makes Manuka honey special, which quality markers matter, and when it makes sense to use.
What is Manuka honey? Origins & uniqueness
Manuka honey comes from the nectar of the Manuka tree (Leptospermum scoparium), native mainly to New Zealand. It stands apart from common honeys through its unusual antimicrobial power.
The key is its high content of methylglyoxal (MGO), which confers potent antibacterial, antiviral, and antifungal activity. MGO forms from plant-derived dihydroxyacetone (DHA) during storage.
Evidence-backed benefits of Manuka honey
1. Antibacterial action through MGO
Multiple studies show Manuka honey has markedly stronger antibacterial activity than typical honeys—including effects against multi-drug resistant strains. This makes it increasingly interesting for wound care and infection prevention.
MGO is considered the principal driver of antimicrobial activity and remains comparatively stable with storage. Depending on MGO level, Manuka honey can inhibit pathogens such as:
- Staphylococcus aureus (skin & wound infections)
- Helicobacter pylori (gastric ulcers, gastritis)
- MRSA (methicillin-resistant S. aureus)
2. Support for wound healing
In modern wound care, Manuka honey (incl. standardized medical products like Medihoney®) is used worldwide, especially for chronic or infected wounds. Clinical data and case reports show it can:
- Accelerate healing
- Reduce infections (even with resistant germs)
- Lower odor & exudate
- Ease pain via moist wound environment
A 2015 Cochrane review found benefits particularly for superficial burns and some postoperative wounds; data for chronic ulcers are mixed and call for more trials.
3. Oral & throat inflammation
Manuka honey can soothe sore throats, cough, and gingivitis by reducing harmful oral microbes and calming irritated mucosa. A 2023 trial in children with chemotherapy-related oral mucositis reported significantly less severity and pain with Manuka honey.
Everyday use: how to apply Manuka honey
Internal use
1) Immune support: Take 1 tsp daily on an empty stomach; let it dissolve in the mouth to bathe mucosa.
2) Colds & sore throat: 1–2 tsp daily; or dissolve in warm (≤40 °C/104 °F) tea. Avoid boiling water to protect MGO.
3) Digestive comfort: 1 tsp before meals; can calm gastric mucosa and support a balanced gut microbiome over several weeks.
Topical use
1) Wound care: Apply a thin sterile layer; cover if needed. Prefer medical-grade Manuka honey (e.g., Medihoney®).
2) Acne or inflamed skin: Thin layer for 15–20 minutes, then rinse; repeat 2–3×/week.
3) DIY masks: Blend with clay, yogurt, aloe, or oats for soothing, hydrating care.
MGO & quality: What do MGO 100, 250, 400 mean?
MGO indicates mg methylglyoxal per kg honey—the core bioactive marker. Typical ranges:
| MGO | Potency | Typical use |
| 100+ | Mild antibacterial | Daily intake, immune support |
| 250+ | Moderate | Sore throat, mild skin issues |
| 400+ | Strong | Therapeutic support for infections/inflammation |
| 550–800+ | Very strong / medical | Wounds, severe mucositis, resistant germs |
UMF® is a protected NZ quality mark factoring in MGO, leptosperin, and DHA; MGO is the precise potency marker, UMF a broader quality seal.
Bottom line: Manuka honey as a natural remedy
Manuka honey is a well-researched natural product with impressive antibacterial effects. It can aid skin issues, cold symptoms, and immune support—provided you choose verified quality and an appropriate MGO level.
