Summary
# Editorial Summary Healing of contaminated wounds on the distal forelimb presents particular challenges in equine practice, as this region's limited soft tissue and poor vascularisation often result in delayed epithelialisation and significant scar contracture. Bischofberger and colleagues investigated whether daily application of manuka honey might improve second-intention healing outcomes in eight Standardbred horses, each bearing deliberately contaminated full-thickness wounds on both third metacarpi; one limb received topical honey whilst the contralateral limb served as untreated control, with wounds measured from day 1 through 8 weeks post-creation. Manuka honey significantly reduced wound contraction and maintained smaller wound areas through day 42, suggesting a genuine therapeutic effect on the wound healing trajectory during the critical inflammatory and proliferative phases. Despite this dimensional advantage during active healing, treated and control wounds ultimately achieved complete epithelialisation in equivalent timeframes, indicating that whilst honey modulates the healing process favourably, it does not accelerate overall closure. For practitioners managing contaminated distal limb wounds, these findings suggest manuka honey could be a valuable adjunct for minimising contracture-related scarring and maintaining larger wound dimensions during healing, potentially preserving functional outcomes—though recognition that it represents optimisation rather than acceleration of healing remains essential for appropriate client expectations and post-wound management planning.

Practical Takeaways
- •Manuka honey may benefit distal limb wound management by reducing retraction and maintaining smaller wound area during healing, even though final healing time is unchanged
- •Consider manuka honey as an adjunctive treatment for contaminated distal limb wounds where minimizing retraction and wound area is a management priority
- •Expect healing timelines to remain similar with or without manuka honey, so don't rely on it to accelerate complete closure
Key Findings
- •Manuka honey application significantly reduced wound retraction compared to control wounds
- •Treated wounds remained significantly smaller than control wounds through day 42
- •Manuka honey treatment did not reduce overall healing time to complete closure
