Manuka Honey
A methylglyoxal (MGO)-rich honey from the manuka tree (Leptospermum scoparium). Its strongest evidence is TOPICAL — as a wound and burn dressing — not as a dietary supplement. Oral claims for sore throat, cough, and H. pylori rest on thin, largely non-manuka-specific or in-vitro data.
What the evidence says
Most Manuka Honey studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality meta-analyses and randomised trials published 2004–2026.
Based on 27 studies · 2 meta-analyses · 17 RCTs
Confidence
High confidenceScores low as a dietary supplement because its real evidence is topical wound care (low-certainty Cochrane reviews); oral data are a non-manuka cough RCT and an in-vitro H. pylori screen, with no systemic human benefit shown.

Manuka honey is a monofloral honey produced by bees foraging on the manuka tree (Leptospermum scoparium) in New Zealand and Australia.
Unlike ordinary honey, its antibacterial activity is driven largely by methylglyoxal (MGO), a non-peroxide compound formed from dihydroxyacetone in the nectar — products are graded by MGO content (or the related UMF rating). The honest evidence picture is split by route of use.
TOPICALLY, medical-grade manuka honey has a real evidence base as a wound and burn dressing, and it appears as a comparator in multiple Cochrane wound reviews; even there, certainty is often low and it has not consistently beaten standard dressings.
As an ORAL dietary supplement, the data are much thinner: honey (frequently not manuka specifically) modestly helps pediatric nocturnal cough, and the H. pylori rationale is essentially in-vitro. Most consumers buy it as a 'superfood' immune supplement — a use that outruns the evidence. It is also high in sugar.
MGO gives manuka honey a non-peroxide antibacterial activity against a range of bacteria — best demonstrated in topical/laboratory settings, not in the bloodstream after eating it.
High sugar content creates an osmotic, low-water environment and a soothing coating that may calm an irritated throat and ease cough.

Never give any honey — risk of infant botulism (Clostridium botulinum spores).
Use sparingly; it is essentially sugar and will affect blood glucose.
Use only medical-grade (sterilized) product for any wound application; consult a clinician.
As a concentrated sugar, it can raise blood glucose — account for it in carbohydrate counting and glucose management.
Tip: Limit portions; people with diabetes should treat it as sugar
Tip: Rinse/brush; avoid frequent sipping
Tip: Avoid if allergic to honey, pollen, or bee products
Manuka Honey has an evidence score of 3/10 — emerging evidence based on 7 indexed studies. A methylglyoxal (MGO)-rich honey from the manuka tree (Leptospermum scoparium). Its strongest evidence is TOPICAL — as a wound and burn dressing — not as a dietary supplement. Oral claims for sore throat, cough, and H. pylori rest on thin, largely non-manuka-specific or in-vitro data. Representative study: PMID 35930364.
The commonly studied dose of Manuka Honey is Oral: ~1-2 teaspoons (about 5-15g) as a throat soother; no validated supplement dose. Topical wound use should be medical-grade product under clinical guidance.. Individual needs vary — start at the lower end of the range and adjust based on how you respond.
Timing is flexible for Manuka Honey — consistent daily use matters more than the time of day. For throat symptoms, taken as needed (often before bed for nocturnal cough).
Manuka Honey is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are blood-sugar spike, dental caries with frequent use, allergic reaction (rare; pollen/bee-product allergy). Use caution if any of these apply to you: Infants under 12 months (risk of infant botulism — NEVER give honey); Diabetes / blood-sugar management (high sugar content).
