Manuka Honey: Benefits, Uses and How to Consume It

IMPORTANT: Manuka honey is a food, not a medicine, and it does not replace treatment prescribed by your doctor. Like all honey, it must not be given to children under 1 year old, because of the risk of infant botulism. People with diabetes should consume it in moderation and monitor their blood sugar, since it remains rich in sugars. Those allergic to pollen, bees or other types of honey should be cautious. If you have a serious wound, an infection that will not heal, a persistent fever or a chronic condition, see a doctor; honey may be a supportive aid, but never a substitute for medical care. Seek your doctor’s advice before applying it to large wounds or if you are on significant medication.

Grandma Veronica, a woman who spent her whole life on the edge of a mountain village, kept a special jar in her pantry that no one was allowed to touch without permission. It was not the ordinary acacia honey she got from her neighbor’s hives, but a thick, dark honey, brought once by a grandson who had traveled far away, all the way from New Zealand. “This is the strong honey,” she would say, and she only brought it out when someone in the house caught a cold, had a sore throat, or had a wound that refused to close. She took it with a little wooden spoon, let it melt slowly in her mouth, and swore it “cut the illness out by the root.”

Back then nobody in the family knew the words “UMF” or “MGO,” nor had they heard of laboratory studies. But Grandma had noticed, with the keen eye of an experienced housewife, something that modern science would later confirm: this particular honey has an antibacterial power well above that of ordinary honey. In the lines that follow we will unravel this story and see what Manuka honey really is, why it came to be considered a superfood, and how you can use it wisely, without falling into the trap of fashion or inflated prices.

Manuka honey is a monofloral honey produced by bees that gather the nectar of the flowers of the Manuka tree (Leptospermum scoparium), a wild plant that grows in New Zealand and in some parts of Australia. What sets it apart from any other honey in the world is its high content of methylglyoxal (MGO), a compound with powerful and stable antibacterial action. That is precisely why, for decades, Manuka honey has been prized both in the healthy kitchen and in the natural care of the throat, the stomach, and the skin.

What Manuka honey is and where it comes from

The Manuka tree is an evergreen shrub that flowers for a short period, only a few weeks each year, covering itself in small white or pale-pink blossoms. During this brief window, beekeepers in New Zealand move their hives into the wild, often hard-to-reach areas where the plant grows. The bees gather the nectar of the flowers, and from it comes a thick, creamy honey, golden-brown to dark brown in color, with an earthy, slightly bitter and distinctive aroma, very different from the sweet, floral honey we are used to.

The Maori, the indigenous people of New Zealand, used both the leaves and bark of the Manuka tree and the honey for centuries as a remedy for wounds, pain and digestive problems. Their traditional knowledge was picked up again by researchers only in the second half of the twentieth century, when scientists began to study why this honey has such unusually strong antibacterial action. This is how the global reputation of Manuka honey was born; today it is exported all over the world and considered one of the most valuable honeys on the market.

Unlike ordinary polyfloral honeys, authentic Manuka honey comes from a single dominant floral source, which gives it its consistent characteristics. Because the harvest is limited, the plant grows wild and demand is enormous, its price is considerably higher than that of ordinary honey. For exactly this reason it is also one of the most counterfeited honeys in the world, which is why strict certification systems exist, as we will discuss below.

What makes it special: MGO, UMF and the antibacterial factor

All honey has some antibacterial action, due to its acidity, low water content, and a small amount of hydrogen peroxide produced enzymatically. But Manuka honey has an additional and unique advantage: a large amount of methylglyoxal (MGO), a compound that forms naturally during the ripening of the honey, from a substance present in the Manuka flower nectar (dihydroxyacetone). Unlike hydrogen peroxide, which easily degrades in light, heat or in contact with the body’s enzymes, MGO is stable. This means the antibacterial action of Manuka honey holds up better, including in the digestive environment or on the skin.

On labels you will find several rating systems. MGO directly indicates the amount of methylglyoxal in milligrams per kilogram (for example, MGO 100+, MGO 250+, MGO 400+, MGO 550+). The higher the number, the greater the antibacterial potency. UMF (Unique Manuka Factor) is an independent certification system that tests not only methylglyoxal but also other authenticity markers, giving a score (for example UMF 5+, UMF 10+, UMF 15+, UMF 20+). As a rough guide, a UMF 10+ corresponds to roughly MGO 250+, and a UMF 15+ to about MGO 500+. Older is also the KFactor system or various other commercial labels, but UMF and MGO remain the most reliable benchmarks.

In short: for everyday maintenance consumption, a honey with MGO 80–250 is sufficient and more affordable; for moments when you want stronger support (an irritated throat, periods of fatigue, digestive discomfort), people usually choose MGO 250–550. Very high concentrations (above MGO 800) are expensive and rarely necessary for home use.

Nutritional value

From a nutritional point of view, Manuka honey resembles other honeys: it is made up mostly of natural sugars (fructose and glucose), with a low water content. A teaspoon provides around 60–70 calories, like any honey. Besides sugars, it contains small amounts of amino acids, B-group vitamins, minerals such as potassium, calcium, magnesium, zinc and iron, as well as antioxidants and phenolic compounds that contribute to its beneficial effects.

It is important to remember that Manuka honey is not consumed for its calories or its sugars, but for its bioactive compounds, primarily methylglyoxal. That is why it is taken in small amounts, a teaspoon or two a day, not by the heaping spoonful. It is a functional food, not an energy source to rely on.

Health benefits

Powerful antibacterial action

The best-known and best-documented property of Manuka honey is its antibacterial effect. Laboratory studies suggest that methylglyoxal can inhibit the growth of a wide range of bacteria, including some resistant to antibiotics. It is precisely this aspect that has made it so prized in natural care and has drawn the attention of researchers worldwide.

Support for sore throat and cough

Folk tradition and everyday experience recommend it for an irritated throat. The thick texture of the honey forms a soothing protective layer over the throat lining, while the antibacterial action contributes to a feeling of relief. A teaspoon taken slowly, left to melt in the mouth, is a simple and pleasant gesture when your throat stings or you have a dry cough.

Digestive comfort

Manuka honey is also valued for its effect on the stomach. Studies suggest it may influence the balance of the gut flora and that it has properties that support digestive comfort. Many use it in the morning, on an empty stomach, to “prepare” their digestion, or after heavy meals for a feeling of relief.

Immune support

Thanks to its antioxidants and active compounds, Manuka honey is used as general support for the body during the cold seasons or periods of fatigue. It is not a “natural vaccine,” but as part of a balanced diet, it contributes to overall well-being.

Skin care and superficial wounds

One of the oldest uses of honey in general is on wounds and skin. Manuka honey, because of its stable antibacterial action, is used in the natural care of skin, blemishes and superficial wounds. In the medical setting there are even sterile dressings based on Manuka honey, but for home use, on small wounds, clean honey can help the healing process. For serious wounds, always see a doctor.

Oral cavity health

Although it is sweet, Manuka honey has an antibacterial action that, paradoxically, is studied for its effect on bacteria in the mouth. Some use it for the feeling of freshness and to soothe irritated gums, but, like any sugary product, it should be followed by good oral hygiene.

Traditional and modern uses

The Maori used the plant and the honey for wounds, pain and stomach problems. Today, Manuka honey has kept these uses but adapted them to the modern world: we find it in the healthy kitchen (in teas, yogurts, dressings), in natural first-aid kits (for the throat and small wounds), and in natural cosmetics (face masks, lip balms, creams). Its versatility comes precisely from the rare combination of taste, texture and antibacterial action.

How to consume Manuka honey (recipes and methods)

Simply, by the teaspoon

The most direct method is to simply take a teaspoon of honey and let it melt slowly in your mouth. This is the ideal way when you want to take advantage of the soothing effect on the throat. Use a wooden or clean plastic spoon and avoid prolonged contact with metal.

In warm water (not hot)

Dissolve a teaspoon of honey in a glass of warm, but not hot, water. Very important: excessive heat (above 40–45°C) degrades the enzymes and part of the beneficial compounds. Wait for the water or tea to cool down a little before adding the honey. You can squeeze in a little lemon for an extra touch of freshness.

In tea or in the “throat remedy”

Prepare your favorite tea (for example ginger, chamomile or thyme), let it cool until it is only warm, and then add a teaspoon of Manuka honey. For an irritated throat, a classic mix is: a teaspoon of Manuka honey, a little lemon juice and a few thin slices of ginger left to steep in warm water.

In yogurt or on bread

For breakfast, add a teaspoon of Manuka honey over plain yogurt, oat flakes or on a slice of whole-grain bread. It is a pleasant way to include it in your daily diet without exposing it to heat.

Salad dressing

Mix a teaspoon of Manuka honey with olive oil, a teaspoon of mustard and a little lemon juice for a healthy, flavorful dressing. The honey adds a distinctive sweet-bitter note.

Face mask (external use)

For skin care, apply a thin layer of clean Manuka honey to the face, leave it on for 10–15 minutes, then rinse with lukewarm water. It is used in the natural care of blemish-prone skin. Do a patch test on a small area of skin first.

How much to consume per day

For maintenance consumption, a reasonable amount is one to two teaspoons a day. There is no need for more; being a honey with strong action and a high sugar content, “more” does not mean “better.” People who want throat support can take it 2–3 times a day, one teaspoon at a time, over a few days. People with diabetes should treat it like any sugar source and discuss it with their doctor.

How to choose authentic Manuka honey

Because it is expensive and highly sought after, Manuka honey is often counterfeited. Here is what to watch for:

• Look for a label with MGO (with a clear number, e.g. MGO 250+) or UMF (e.g. UMF 10+). A honey that mentions no potency indicator is probably not worth the price.
• Check the origin: authentic Manuka honey comes from New Zealand (and, in some cases, from Australia).
• Look for a batch number and an identifiable producer, ideally with the option to verify the certification on the official website.
• Be skeptical of suspiciously low prices: real Manuka honey with high MGO cannot be cheap.
• The texture should be thick and creamy, and the taste earthy and slightly bitter, not just sweet and floral.

How to store it correctly

Manuka honey is stored like any honey: in a cool place, away from direct sunlight, with the lid well closed. Do not keep it in the refrigerator, because it crystallizes faster and becomes hard to scoop. Always use a clean, dry spoon to avoid contamination. Honey has a very long shelf life; if it crystallizes, you can bring it back to a softer texture by placing the jar in a bowl of warm (not hot) water. Avoid strong heating, so as not to destroy the active compounds.

Lifestyle and practical advice

Manuka honey gives the best results when it is part of a balanced lifestyle, not a “magic bullet.” A varied diet rich in vegetables, fruit, fiber and water, enough sleep and regular movement do more for your immunity than any expensive supplement. Use Manuka honey as a small, pleasant daily ritual: a teaspoon in the morning, a warm tea in the evening, a drizzle in yogurt. That way you benefit from its properties without turning it into a needless source of sugar.

Keep your budget in mind too: for everyday consumption you do not need the most expensive versions with huge MGO. An authentic, certified Manuka honey of medium potency is a far wiser choice than a dubious “premium” version bought cheaply from an unknown source.

Practical Tips and Common Mistakes

Mistake no. 1: Adding honey to hot liquids. High heat destroys part of the beneficial compounds. Always let the tea or water cool down to “warm enough to drink.”

Mistake no. 2: Consuming large amounts “by the spoonful.” It remains a source of sugar; one or two teaspoons a day are enough.

Mistake no. 3: Buying without checking the label (MGO/UMF) and the origin. Without these indicators, you pay a high price for a honey that may be ordinary or counterfeit.

Mistake no. 4: Using it for infants. No honey, including Manuka, should be given to children under one year old.

Mistake no. 5: Expecting miracles. Manuka honey is a supportive aid, not a treatment. For serious infections or chronic conditions, see a doctor.

Mistake no. 6: Storing it in the fridge or using a wet spoon. Both shorten the honey’s life and encourage crystallization or contamination.

Mistake no. 7: Ignoring diabetes or allergies. People with diabetes or with allergies to bee products must be cautious and seek their doctor’s advice.

Conclusion

Manuka honey is, without a doubt, one of the most valuable honeys in the world, thanks to its high and stable content of methylglyoxal, which gives it a remarkable antibacterial action. Used wisely, as part of a healthy lifestyle, it can be a pleasant support for the throat, digestion, immunity and skin care. The key is to choose it authentic (checking the MGO/UMF and origin), to consume it in small amounts, not to overheat it, and not to expect from it miracles it cannot deliver. As Grandma Veronica used to say, it is “the strong honey” — but its strength is to be respected, not wasted.

Frequently Asked Questions

What do MGO and UMF on the label mean? MGO directly indicates the amount of methylglyoxal (the antibacterial compound) in mg/kg, while UMF is an independent certification system that confirms authenticity and potency. The higher the numbers, the stronger the antibacterial action. A UMF 10+ corresponds to roughly MGO 250+.

How different is Manuka honey from ordinary honey? All honeys have some antibacterial action, but Manuka honey contains methylglyoxal, a stable compound that gives it much greater potency, more resistant to heat, light and enzymes. Hence its price and its reputation.

Can I put it in hot tea? Not in boiling tea. High heat degrades the beneficial compounds. Let the tea cool until it is only warm before adding the honey.

How much can I consume per day? For maintenance, one to two teaspoons a day are enough. For an irritated throat, you can take a teaspoon 2–3 times a day for a few days. Do not overdo it, as it remains rich in sugar.

Is it safe for children? Not for babies under 1 year old, because of the risk of infant botulism. For older children it is generally safe in small amounts, but moderation remains important.

Can I use it if I have diabetes? With caution. Manuka honey is rich in sugars and can affect blood glucose. Talk to your doctor and monitor your values.

How do I tell if it is authentic? Look for the label with MGO or UMF, the New Zealand origin, an identifiable producer and a batch number. Be skeptical of very low prices and of the absence of any potency indicator.

Can I use it on skin and wounds? Yes, for skin and superficial wounds it is used in natural care. Do a tolerance test first. For serious wounds or infections, consult a doctor.
