What is medical grade honey?
Medical grade honey is honey that has been specifically selected, processed, and standardized for medical and veterinary use. Unlike raw or food-grade honey, it undergoes controlled purification and sterilization (commonly by gamma irradiation) to ensure microbiological safety while preserving its biologically active components.
Its therapeutic activity is based on several well-established mechanisms:
- Low pH, inhibiting bacterial growth
- High osmotic activity, drawing fluid, debris, and bacteria from the wound
- Enzyme-driven hydrogen peroxide release, providing continuous antimicrobial action
- Anti-inflammatory effects, supporting pain reduction and tissue recovery
Medical grade honey is used successfully in: acute and chronic wounds, infected wounds, surgical sites, burns, pressure ulcers and trauma-related wounds
Importantly, medical grade honey is defined by clinical processing and performance, not by a specific floral origin.
What is manuka honey?
Manuka honey is a mono-floral honey derived from the Leptospermum scoparium plant, native to New Zealand. It is widely recognized for its naturally occurring methylglyoxal (MGO) content, which provides an alternative antibacterial mechanism.
Manuka honey is often graded using:
- MGO values
- UMF (Unique Manuka Factor) ratings
These grading systems are primarily designed for food supplement applications. Only when manuka honey is specifically processed, sterilized, and registered for medical use can it be considered a medical grade product appropriate for wound care.
Key distinction: botanical origin vs medical processing
Manuka honey refers to the honey’s origin, while medical grade honey refers to its processing and validation for clinical use.
A honey-based wound product may be:
- Manuka-based and medical grade
- Non-manuka and medical grade
- Manuka-based but not medical grade (food-grade)
Only medical grade processing ensures: sterility, clinical safety, batch-to-batch consistency and predictable antimicrobial activity.
Feature |
Medical grade honey |
Manuka honey |
| Floral origin | Multiple possible sources | Single plant source |
| Sterile for wound use | Yes | Only if medical-grade |
| Main antimicrobial action | Peroxide-based + osmotic + pH | Mainly MGO-based |
| Standardization | Clinical quality controlled | Based on MGO/UMF |
| Suitable for open wounds | Yes | Only if medical-grade |
Do they perform differently in wounds?
Both Manuka-based and non-Manuka Medical Grade honeys have shown:
- Broad-spectrum antibacterial activity
- Support for autolytic debridement
- Creation of a moist wound environment
- Anti-inflammatory effects
- Stimulation of granulation tissue and re-epithelialization
From a clinical standpoint, the decisive factor is not whether the honey is Manuka, but whether it is Medical Grade.
Why some medical honey products do not depend on manuka?
Some medical honey formulations, intentionally use standardized non-Manuka Medical Grade Honey. This allows for:
- Controlled enzyme activity
- Stable and predictable hydrogen peroxide release
- Consistent antimicrobial performance
- Less dependency on fluctuating MGO levels
- Reliable clinical effects, even in moist wound environments
