Medical Grade Manuka Honey for Wound Care: What You Need to Know

The evidence-backed guide to medical Manuka honey, Therahoney, Activon, and what happened to Medihoney

There’s a jar of honey sitting on pharmacy shelves that costs $50, sometimes $100 or more. It doesn’t come with a pharmacological compound name or a clinical-sounding label. It’s just honey; from a small white flower native to New Zealand. And yet doctors, wound care specialists, and researchers worldwide are taking it very seriously.

Welcome to the world of medical grade Manuka honey, a natural, evidence-backed wound care product now used in hospitals around the world. Whether you’ve heard of Therahoney, Activon, or the now-discontinued Medihoney, this guide will walk you through everything you need to know.

What Is Medical Grade Manuka Honey?

Manuka honey is produced by bees that pollinate Leptospermum scoparium, commonly known as the Manuka bush, a flowering shrub native to New Zealand and parts of southeastern Australia. While all honey has some antimicrobial properties, Manuka honey contains significantly higher levels of a compound called methylglyoxal (MGO).

MGO is the key bioactive ingredient responsible for Manuka honey’s potent antibacterial activity. The higher the MGO concentration, the more powerful the antimicrobial effect. This is what sets Manuka apart from ordinary honey and what makes medical grade Manuka honey, a legitimate clinical tool for wound care.

UMF and MGO Ratings: What They Mean

If you’ve shopped for Manuka honey, you’ve likely encountered confusing labels like “UMF 15+” or “MGO 514+.” Here’s what they mean:

•      MGO (Methylglyoxal): Measures the concentration of the key antibacterial compound directly in mg/kg. MGO 100+ is low potency; MGO 550+ is high potency and suitable for therapeutic wound care use.

•      UMF (Unique Manuka Factor): A grading system developed by the Unique Manuka Factor Honey Association (UMFHA) that tests for MGO, DHA, leptosperin, and HMF to ensure authenticity and quality. UMF 10+ is the minimum considered to have meaningful medicinal properties.

For medical use, most clinicians and wound care products use UMF 12+ or MGO 400+ as a starting benchmark.

What Does the Science Say About Manuka Honey for Wound Care?

This isn’t folk medicine. Over the past two decades, a robust body of peer-reviewed research has examined Manuka honey’s medical properties in wound healing and infection control.

Wound Healing

Perhaps the most well-established application of medical grade Manuka honey is wound care. It creates a moist healing environment, has a low pH that inhibits bacterial growth, and produces hydrogen peroxide through enzymatic activity. Medical grade Manuka honey wound dressings are now widely used in hospitals for:

•      Chronic wounds

•      Venous Ulcers and Diabetic Ulcers

•      Burns and skin grafts

•      Post-surgical wounds

•      Pressure injuries

Studies have shown medical grade Manuka honey dressings can reduce wound healing time, decrease infection rates, and even help with wounds that have not responded to conventional treatments.

Antibiotic-Resistant Bacteria (MRSA)

One of the most significant areas of Manuka honey wound care research is its effectiveness against methicillin-resistant Staphylococcus aureus (MRSA), the “superbug” that is resistant to many standard antibiotics. Multiple studies have demonstrated that Manuka honey can inhibit MRSA growth in laboratory settings and has shown promise in clinical wound applications.

Crucially, because Manuka honey attacks bacteria through multiple pathways (osmotic stress, low pH, reactive oxygen species, and MGO disruption of bacterial proteins), it is very difficult for bacteria to develop resistance to it.

What Happened to Medihoney? (And What to Use Instead)

If you’ve searched for medical grade Manuka honey and keep seeing “Medihoney” in articles and hospital guides, here’s what you need to know.

Medihoney was one of the first medical grade Manuka honey products to reach the market and played a major role in bringing honey-based wound care into mainstream clinical practice. The name became so synonymous with the product category that honey wound dressings are often still referred to as “Medihoney” much like tissues can be called “Kleenex” or soda is called “Coke.”

However, Medihoney is not currently being produced and has been recalled. If you are able to find an actual tube of Medihoney brand, the manufacturer is instructing you to discard it. It is not safe to use.

The trusted alternatives available today are Therahoney and Activon. Both are medical grade Manuka honey products manufactured to the same high clinical standards.

 

Medical Grade vs Table Honey: A Critical Distinction

Not all Manuka honey is suitable for wound care. Medical grade Manuka honey is:

•      Sterilized by gamma irradiation (to eliminate any potential spores)

•      Tested and standardized for potency

•      Manufactured to pharmaceutical standards

•      Certified for wound care use (e.g., under the CE mark in Europe or FDA clearance in the US)

Table-grade Manuka honey, even high-UMF varieties from a grocery store, has not been sterilized and should never be applied to open wounds. For wound care, always use a medical grade product like Therahoney or Activon.

What Forms Does Medical Grade Manuka Honey Come In?

Medical grade Manuka honey wound care products are available in two primary forms:

•      Honey Gel/Ointment: Products like Activon and Therahoney are 100% Manuka honey and are available as a gel that can be applied directly to the wound bed, either on its own or under a secondary dressing.

•      Pre-impregnated Dressings: Both Activon and Therahoney also offer gauze  dressings that are pre-treated (impregnated) with medical grade Manuka honey, making application quick and consistent. The sheets help facilitate wound closure while permitting the drainage of fluid into a secondary or outer dressing.

How to Use Manuka Honey Wound Dressings

Apply medical grade Manuka honey directly to a clean wound bed or use pre-impregnated dressings such as Therahoney or Activon gauze. Change dressings every 2–3 days, or as directed by a healthcare provider.

Precautions and Contraindications

Medical grade Manuka honey is generally well tolerated for wound care, but keep these important considerations in mind:

 

•      Infants under 12 months should never be given any honey internally due to the risk of infant botulism.

•      Bee or honey allergies are a contraindication for use.

•      Always consult a healthcare provider before using Manuka honey as part of a treatment plan for serious conditions.

The Bottom Line

Medical grade Manuka honey sits at a fascinating intersection of traditional medicine and cutting-edge science. It is not a cure-all, and it is not a replacement for professional medical care when that is needed. But the evidence for its efficacy, particularly in wound healing, chronic wounds, and antimicrobial applications, is genuine, substantial, and growing.

For those seeking a natural, evidence-backed therapeutic wound care tool, medical grade Manuka honey deserves its place in the clinical toolkit. Just make sure you’re using the real thing: certified UMF or MGO ratings, verified New Zealand or Australian origin, and for wound care, always medical grade.

Sometimes, nature gets it right.

Always consult a qualified healthcare professional before using Manuka honey as a medical treatment, especially for serious or infected wounds.
