Diabetic foot ulcers (DFUs) are one of the most common reasons tissue-viability nurses choose a medical honey dressing. Three features of honey line up well with the way diabetic ulcers misbehave: it lifts slough without surgery (autolytic debridement), it has activity against the bacteria that commonly colonise these wounds (including MRSA and Pseudomonas), and it maintains a moist healing environment.
How honey is used on a DFU
- A sterile honey product (typically Activon, Algivon, Medihoney or L-Mesitran) is placed in direct contact with the ulcer bed.
- An absorbent secondary dressing manages the extra fluid honey draws out.
- Dressing changes are usually every 1–3 days at first, settling to less often as the wound improves.
- It is always combined with the rest of standard DFU care: offloading (total-contact cast, removable walker or bespoke insole), vascular review, glycaemic control, and infection screening.
Does it affect blood sugar?
No. The honey absorbed through a wound is a tiny fraction of a teaspoon over a dressing change — far below the threshold for measurable glycaemic impact. Continue your normal monitoring schedule. Let your diabetes team know honey is being used so they have the full picture, but it does not need a change to your insulin or oral therapy.
What does the evidence say?
Several randomised trials and a Cochrane Wounds Group review have looked at honey versus standard dressings for diabetic and other chronic ulcers. The pattern across studies is consistent:
- Faster slough clearance and reduced odour in the first 1–2 weeks.
- Reductions in wound surface bacteria, including MRSA.
- Mixed evidence for time to full closure — outcomes depend at least as much on offloading, circulation and glycaemic control as on the dressing.

Red flags — call your team the same day
- Redness spreading away from the ulcer edge
- New or worsening pain, especially in a foot that was previously numb
- Fever, chills, or feeling generally unwell
- Sudden increase in fluid, pus, or a foul odour
- Black or purple discolouration around the ulcer
Frequently asked questions
Does medical honey raise my blood sugar?
No. The amount of sugar absorbed through a wound is too small to influence systemic blood-glucose levels. Medical honey is widely used on diabetic foot ulcers without affecting glycaemic control. Continue your normal monitoring.
How long until a diabetic foot ulcer heals with honey dressings?
Diabetic foot ulcers are slow-healing by nature. Many ulcers look cleaner — less slough, less odour — within 1–2 weeks of honey dressings. Full closure typically takes weeks to months and depends on offloading, circulation, glycaemic control and nutrition. Honey is an adjunct, not a replacement for the rest of standard diabetic foot care.
Will it work on an infected ulcer?
Medical honey has antibacterial activity against organisms including MRSA and Pseudomonas, and is used on lightly infected wounds alongside, not instead of, systemic antibiotics when the clinician judges them necessary. Clinically infected ulcers always need clinician assessment.
Can I dress my own diabetic foot ulcer at home?
Diabetic foot ulcers should always be managed by your diabetes / podiatry / tissue-viability team — not self-treated. They will choose the dressing (honey or otherwise), set the change frequency, arrange offloading and check for infection. You may apply between visits to the schedule they set.
