Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Manuka honey is a New Zealand honey with genuine antibacterial activity, valued especially for wound care and sore throats. Eaten as a food its broader claims are weaker.
What is Manuka Honey?
Manuka honey is produced from the manuka bush (Leptospermum scoparium) in New Zealand and Australia, prized for unusually strong antibacterial activity, graded by 'UMF' or methylglyoxal content.
What Manuka Honey is commonly used for
In supplements, Manuka Honey is most often included for oral & dental health, skin & anti-aging, respiratory & lung health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Manuka Honey works
Beyond the hydrogen peroxide common to honey, manuka contains methylglyoxal (MGO), which gives it extra antibacterial power — the basis for its use in wound dressings and throat soothing.
What the evidence says
Here's an honest snapshot of what published research suggests about Manuka Honey — including where the evidence is limited.
- Medical-grade manuka honey has real evidence in wound care, and honey generally helps soothe coughs and sore throats. Claims that eating manuka honey treats internal infections or boosts immunity broadly are weaker.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Manuka Honey rather than relying on marketing claims.
Typical dosage used in studies
Wound products use medical-grade honey; for throat soothing, a teaspoon is typical. It is still sugar, so amounts matter for blood sugar and teeth. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Manuka honey is a sugar and should be limited by people with diabetes and avoided in infants under 12 months (botulism risk). Use medical-grade products for wounds rather than food-grade jars. As with any supplement, it's sensible to introduce Manuka Honey on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Manuka Honey
Medication & safety check
Manuka Honey can interact with certain medications or health conditions in ways that aren't always obvious. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Manuka Honey is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Manuka Honey with your doctor or pharmacist first.
