Manuka honey benefits: between the pharmacy shelf and the marketing claim, there is often a big gap. Jars carry numbers like “MGO 400+” or “UMF 15+”, the internet talks about miracle cures, and according to Germany's Apotheken Umschau the industry sells around 10,000 tonnes of manuka honey a year while only about 1,700 tonnes are produced.

That raises two questions. What can manuka honey actually do, and what does any of it have to do with a salve for daily skin care? The short answer: the most impressive data comes from the lab and from wound care with sterile, medical-grade honey. A skincare salve is a different thing.

Here we sort it out. You will see what MGO means, which studies exist, where their limits are, and how to use the Manuka Honey Hemp Salve sensibly if your skin is dry, cracked or tight.

Research Spotlight

Up to 1,200 mg/kg MGO: manuka honey holds up to 60 times more than regular honey

Source: Apotheken Umschau, 13 March 2026 (regular honey: up to 20 mg/kg MGO)

Manuka honey is made by bees from the nectar of the manuka shrub (Leptospermum scoparium), which grows in New Zealand and southeastern Australia. The Māori traditionally used the plant's leaves, essential oil and honey for inflammation, infections and colds.

What sets it apart from other honey is mainly a compound called methylglyoxal, or MGO. It forms while the honey ripens, from a component of manuka nectar. Regular honey contains at most about 20 mg of MGO per kilogram, manuka honey up to 1,200 mg/kg. If the jar says “400+”, that means at least 400 mg/kg.

You will also see the UMF scale (Unique Manuka Factor). According to a review in AIMS Microbiology (2018), it correlates with MGO and total phenol content. So what is being measured is chemistry, not magic.

A shopping note: according to Apotheken Umschau there is no single reliable authenticity seal. German consumer advice recommends buying from members of the UMF association or the Australian Manuka Honey Association, because their honey is tested and certified.

One more point of context: in Germany manuka honey is not a drug. Products for wound care are sold as medical devices, and different quality rules apply to them than to a jar from the supermarket.

The evidence is good for sterile medical-grade honey in wound care, and thin for jar honey or skincare products. That distinction is the most important sentence in this article.

Apotheken Umschau points to a large review of 26 studies with roughly 3,000 patients. For burns, wounds healed faster with manuka honey than with conventional dressings. The Pharmazeutische Zeitung explains why that is plausible: the honey draws fluid out of the wound, and its pH of about 3.5 to 4.5 makes it harder for many bacteria to grow. Medical honey is sterilised with cobalt-60 gamma radiation and has to meet pharmacopoeia quality, for example a maximum of 80 ppm hydroxymethylfurfural (HMF), a marker of age and processing.

In the lab, manuka honey shows strong antibacterial activity. The review by Johnston and colleagues (AIMS Microbiology, 2018) notes that Gram-negative bacteria are more resistant than Gram-positive ones and that no bacterial resistance to honey has been identified so far. Apotheken Umschau adds that MGO may break down biofilms, but so far only in a test tube.

The limits are stated in the literature too. A review by Nolan and colleagues (Antibiotics, 2019) bases its wound statements partly on just two individual cases, gives no solid numbers for skin grafts and burns, and warns that low honey concentrations can even promote biofilm formation by Staphylococcus aureus. Activity also varies with origin and processing.

For colds the picture is weaker still: according to Apotheken Umschau it is not well studied whether manuka honey works better than regular honey. The German cough guideline does not explicitly recommend honey.

What does that mean for skin? Studies on ingredients are not proof for a specific skincare product. Honey is a humectant that binds moisture, and a salve with beeswax forms a protective film. How that feels on your skin depends on your skin. The Manuka Honey Hemp Salve is a care product for dry, cracked skin. It does not replace a sterile wound dressing or medical treatment.

Apply the Manuka Honey Hemp Salve once or twice a day in a thin layer on clean, dry skin. According to the product description it contains manuka honey, propolis, beeswax, panthenol, aloe vera and hemp, and it is intended for dry, cracked skin.

1. Clean the area. Lukewarm water, mild wash lotion, pat the skin dry instead of rubbing.
2. Patch test. Pea-sized amount on the inside of the elbow, wait 24 hours. Do not use it if you react.
3. Apply thinly. Warm a small amount between your fingers and massage in gently. More is not better, it only leaves a film.
4. Plan it for the evening. After handwashing and before bed is when care can last longest. For very dry hands, cotton gloves over the salve help.
5. Stay consistent. Allow a few days before judging whether the care suits you. If your skin has not changed after two weeks, ask at the pharmacy or your doctor's office.

For sensitive areas, or if you prefer a richer texture, the Organic Manuka Oat Repair Butter 100ml is a good complement. According to its product description it contains manuka honey, propolis, calendula and hemp oil and is intended for dry, sensitive skin. Both products are care, not treatment.

The most common mistake is spreading jar honey on an open wound. According to Apotheken Umschau, food-grade manuka honey is not sterile and does not belong on open wounds. For wounds there are approved sterile medical products, available at the pharmacy.

Mistake two: treating the MGO number as the quality measure for everything. A higher value means higher antibacterial activity in the lab and a higher price. It does not say whether a skincare salve is better for your skin. Tolerance is what counts.

Mistake three: eating too much honey. Honey is mostly sugar. According to Apotheken Umschau it is no healthier than table sugar apart from its antimicrobial compounds, it sticks to teeth and promotes tooth decay. Spoonfuls of manuka honey are not a good idea, least of all with diabetes.

Mistake four: believing healing promises. For foods, claims such as “cures” or “relieves disease” are not permitted in the EU, as consumer advice centres point out. If a seller advertises with them, treat it as a warning sign.

Mistake five: overlooking allergies. If you react to honey or bee products, skip manuka honey, and skip salves containing propolis. And children under one year should not be given any honey, including manuka honey, because of the risk of infant botulism from Clostridium botulinum spores.

⚠️ Important Note

Open, weeping or inflamed wounds belong in a doctor's hands. Use neither jar honey nor a skincare salve on them. See a doctor or pharmacist too if a skin change lasts longer than two weeks, or comes with fever, strong redness or pain. Children under one year should never be given honey.

✅ Key Takeaways

• Strong data on manuka honey benefits exists for sterile medical-grade honey in wound care, not for jar honey.
• The MGO value (up to 1,200 mg/kg) tells you about lab activity, not about how suitable a skincare salve is.
• Manuka honey does not belong on open wounds, with children under one year, or with people allergic to honey.

Manuka honey benefits are real, but narrower than advertising suggests. They are well supported for sterile medical-grade honey in wound care and, in the lab, for the antibacterial activity of MGO. For skincare products and jar honey, that data does not automatically carry over.

If you want to care for dry, cracked skin, a good salve is a sensible choice. The Manuka Honey Hemp Salve and the Organic Manuka Oat Repair Butter 100ml are made for that. They do not replace a doctor's visit, and for wounds or lasting symptoms you are better off at the pharmacy or the doctor's office.
