Honey for burns and cough: where the evidence is strongest

World Apitherapy Organization · November 9, 2026

Honey is one of the oldest products of the hive, and also one of the best studied. At the World Apitherapy Organization we read every finding with three labels: evidence, with the level at which it was observed (lab, animal or human studies); inference, our own reasoning, marked so that you can judge it; and not proven, for ideas that circulate without support. This is where the evidence on honey goes furthest.

Partial-thickness burns: honey's most solid result.

Evidence · human studies A 2015 Cochrane review brought together 26 trials with 3,011 people and many kinds of wounds. Its strongest finding is in partial-thickness burns, those that do not go through the full thickness of the skin: in 2 trials with 992 people, burns dressed with honey closed on average 4.7 days sooner than burns with conventional dressings, such as polyurethane film, paraffin gauze or sterile linen. The review rated that evidence as high quality, the top of its four ratings (Jull et al., Cochrane Database of Systematic Reviews, 2015).

Evidence · human studies The same review found, in a single trial with 50 people, that infected postoperative wounds closed sooner with honey than with antiseptic washes followed by gauze, with moderate-quality evidence (Jull et al., 2015).

Why the result is biologically plausible.

Evidence · lab studies In pure honey, the very high sugar concentration draws water out of bacteria by osmosis. When honey is diluted, an enzyme that acidity keeps inactive in the jar, glucose oxidase, switches on and releases hydrogen peroxide slowly and continuously (Almasaudi, Saudi Journal of Biological Sciences, 2021).

Evidence · lab studies Polyphenols from plants, 1,2-dicarbonyl compounds such as methylglyoxal and defensin-1, a peptide supplied by the bee, add to those routes. Their concentrations depend on the nectar source, the type of bee and storage, so two honeys need not act in the same way (Almasaudi, 2021).

Evidence · lab studies Honey's acidity, with a pH of 3.5 to 4, is linked to lower activity of proteases in the wound, more oxygen released from hemoglobin and more activity of fibroblasts and macrophages, cells that take part in tissue repair (Almasaudi, 2021).

Inference The lab mechanisms and the result in people point in the same direction. When two levels of evidence agree, plausibility gains strength.

Acute cough in children: relief with moderate certainty.

Evidence · human studies A 2018 Cochrane review included 6 randomized trials with 899 children aged 1 to 18 with acute cough. Compared with giving nothing or a placebo, honey probably reduced cough frequency more, with moderate-certainty evidence. Compared with diphenhydramine it may reduce it more, and compared with dextromethorphan it may have a similar effect, both with low certainty (Oduwole et al., Cochrane Database of Systematic Reviews, 2018).

Evidence · human studies The relief was clearest in the first days: for up to three days, honey probably relieved cough symptoms more than a placebo, and beyond three days it probably had no advantage. Most children received honey for a single night, a limitation the authors point out (Oduwole et al., 2018).

Evidence · human studies A 2021 systematic review widened the view to upper respiratory tract infections and included 14 studies. Compared with usual care, honey improved a combined symptom score and reduced cough frequency and cough severity. Only 2 placebo-controlled studies could be combined, and the authors call for high-quality placebo-controlled trials (Abuelgasim et al., BMJ Evidence-Based Medicine, 2021).

Chronic wounds: the frontier of research.

Inference The osmotic effect, the slow release of peroxide and the acidity make a benefit of honey dressings in slow wounds, such as venous leg ulcers and diabetic foot ulcers, biologically plausible.

Evidence · human studies In the 2015 review there were 2 trials in each of those wounds, rated low quality, and the effect of honey remained unclear (Jull et al., 2015). Low quality is not a verdict: the mechanism is described, and the next link is larger, better-designed trials that say in whom and in which wounds the benefit appears.

How to keep reading on your own.

The search for the wounds review closed in October 2014. To look for later trials, type honey AND diabetic foot in PubMed, tick the Systematic Review or Meta-Analysis filter and sort by date. In each abstract, read how the authors rated each comparison: compared with what, in whom, for how long, and with what certainty.
