It’s produced by bees who pollinate the flower Leptospermum scoparium, commonly known as the Manuka bush.

Manuka honey’s antibacterial properties are what set it apart from traditional honey.

Methylglyoxal is its active ingredient and is likely responsible for these antibacterial effects.

Additionally, Manuka honey has antiviral, anti-inflammatory, and antioxidant benefits.

It has traditionally been used for wound healing, soothing sore throats, preventing tooth decay, and improving digestive issues.

Here are 7 science-based health benefits of Manuka honey.

1. Manuka honey can aid in wound healing

Since ancient times, honey has been used to treat wounds, burns, sores, and boils.

In 2007, Manuka honey was approved by the US FDA as an option for wound treatment.

Honey offers antibacterial and antioxidant properties while maintaining a moist wound environment and a protective barrier, which prevents microbial infections in the wound.

Multiple studies have shown that Manuka honey can enhance wound healing, amplify tissue regeneration, and even decrease pain in patients suffering from burns.

For example, one two-week study investigated the effects of applying a Manuka honey dressing on 40 people with non-healing wounds.

The results showed that 88% of the wounds decreased in size. Moreover, it helped create an acidic wound environment, which favors wound healing.

What’s more, Manuka honey may help heal diabetic ulcers.

A Saudi Arabian study found that Manuka honey wound dressings when combined with conventional wound treatment, healed diabetic ulcers more effectively than conventional treatment alone.

Additionally, a Greek study showed that Manuka honey wound dressings reduced healing time and disinfected wounds in patients with diabetic foot ulcers.

Another study observed the effectiveness of Manuka honey in healing eyelid wounds after surgery. They found all eyelid wounds healed well, regardless of whether the incisions were treated with Manuka honey or vaseline.

However, patients reported scarring treated with Manuka honey was less stiff and significantly less painful than those treated with vaseline.

Lastly, Manuka honey effectively treats wound infections caused by antibiotic-resistant strains, such as Staphylococcus aureus (MRSA).

Hence, the regular topical application of Manuka honey on wounds and infections may help prevent MRSA.

Summary: Applied topically, Manuka honey effectively treats burns, ulcers, and non-healing wounds. It has also been shown to combat antibiotic-resistant strains of infections, such as MRSA.

2. Manuka honey promotes oral health

According to the CDC, almost 50% of Americans have some form of periodontal disease.

To avoid tooth decay and keep your gums healthy, minimizing harmful oral bacteria that can cause plaque formation is essential.

It’s also important not to wipe out the good oral bacteria responsible for keeping your mouth healthy.

Studies have shown Manuka honey attacks harmful oral bacteria associated with plaque formation, gum inflammation, and tooth decay.

Specifically, research has shown that Manuka honey, with high antibacterial activity, is effective at inhibiting the growth of harmful oral bacteria like P. gingivalis and A. actinomycetemcomitans.

One study examined the effects of chewing or sucking on a honey chew on reducing plaque and gingivitis. The honey chew was made of Manuka honey and is similar to a chewy honey candy.

After their three daily meals, participants were instructed to either chew or suck on the honey chew for 10 minutes or chew sugar-free gum.

The honey-chew group showed a significant reduction in plaque and gingival bleeding compared to those who chewed the sugar-free gum.

The idea of consuming honey for good oral health may seem counterintuitive, as you have probably been told that consuming too many sweets can lead to cavities.

However, unlike candy and refined sugar, Manuka honey’s potent antibacterial effects make it unlikely to contribute to cavities or tooth decay.

Summary: Research shows Manuka honey inhibits the growth of harmful oral bacteria that can cause gingivitis and tooth decay. Unlike refined sugar, it has not been shown to cause tooth decay.

3. Manuka honey soothes a sore throat.

If you are suffering from a sore throat, Manuka honey may help provide some relief.

Its antiviral and antibacterial properties can reduce inflammation and attack the bacteria that cause pain.

Not only does Manuka honey attack harmful bacteria, but it also coats the inner lining of the throat for a soothing effect.

A recent study in patients undergoing chemotherapy treatment for head and neck cancer observed the effects of consuming Manuka honey on Streptococcus mutans, a type of bacteria responsible for sore throats.

Interestingly, researchers found a significant decrease in Streptococcus mutans after they consumed Manuka honey.

Moreover, Manuka honey decreases harmful oral bacteria that cause mucositis, a common side effect of radiation and chemotherapy. Mucositis results in inflammation and painful ulcerations of the mucous membranes lining the esophagus and digestive tract.

For quite some time, various types of honey have been touted as natural cough suppressants.

One study found honey was as effective as a common cough suppressant.

Although Manuka honey wasn’t used in this study, it’s likely to be just as effective at suppressing coughs.

Summary: Manuka honey can help treat sore throats. Research shows it attacks bacteria that cause soreness, especially in chemotherapy or radiation patients.

4. Manuka honey helps prevent gastric ulcers

Stomach ulcers are one of the most common illnesses affecting humans.

They are sores that form on the stomach lining, causing stomach pain, nausea, and bloating.

H. pylori is a common type of bacteria that is responsible for the majority of gastric ulcers.

Research suggests that Manuka honey may help treat gastric ulcers caused by H. pylori.

For example, a test-tube study examined its effects on the biopsies of gastric ulcers caused by H. pylori. The results were positive and implied that Manuka honey is a beneficial antibacterial agent against H. pylori.

However, a two-week study of 12 individuals who took 1 tablespoon of Manuka honey by mouth daily showed that it did not decrease H. pylori bacteria.

Thus, more research is needed to fully assess its ability to treat gastric ulcers caused by H. pylori.

Gastric ulcers can also be caused by excessive alcohol consumption.

Yet, a study in rats showed that Manuka honey helped prevent alcohol-induced gastric ulcers.

Summary: The research is mixed, but Manuka honey’s potent antibacterial effects may help treat gastric ulcers caused by H. pylori. It may also prevent alcohol-induced gastric ulcers.

5. Manuka honey improves digestive symptoms

Irritable bowel syndrome is a common digestive disorder.

Its associated symptoms include constipation, diarrhea, abdominal pain, and irregular bowel movements.

Researchers have discovered that regularly consuming Manuka honey may help decrease these symptoms.

Manuka honey has been proven to improve antioxidant status and reduce inflammation in rats with irritable bowel syndrome and ulcerative colitis, a type of inflammatory bowel disease.

It has also been shown to attack strains of Clostridium difficile.

Clostridium difficile, often called C. diff, is a type of bacterial infection that causes severe diarrhea and inflammation of the bowel.

C. diff is commonly treated with antibiotics. However, a recent study observed the effectiveness of Manuka honey on C. diff strains.

Manuka honey killed C. diff cells, making it a possibly effective treatment.

It is important to note that the above studies observed Manuka honey’s influence on bacterial infections in rat and test-tube studies.

Further research is needed to come to a full conclusion regarding its influence on bacterial infections of the bowel.

Summary: Manuka honey may decrease inflammation in individuals with irritable bowel syndrome. It may also be effective at attacking Clostridium difficile.

6. Manuka honey may treat symptoms of cystic fibrosis

Cystic fibrosis is an inherited disorder that damages the lungs and can also affect the digestive system and other organs.

It affects the cells that produce mucus, causing mucus to be abnormally thick and sticky. This thick mucus clogs airways and ducts, making it difficult to breathe.

Unfortunately, upper respiratory infections are pretty common in people with cystic fibrosis.

Manuka honey has been shown to fight bacteria that cause upper respiratory infections.

Pseudomonas aeruginosa and Burkholderia spp. are two common bacteria that can cause severe upper respiratory infections, especially in vulnerable populations.

One study observed the effectiveness of Manuka honey against these bacteria in people with cystic fibrosis.

Results indicated that it inhibits their growth and works with antibiotic treatment.

Therefore, researchers concluded that Manuka honey might be essential in treating upper respiratory infections, especially in cystic fibrosis patients.

Summary: Manuka honey has been shown to attack harmful bacteria that cause upper respiratory infections in individuals with cystic fibrosis, but further studies are needed.

7. Manuka honey might help treat acne

Acne is usually caused by hormonal changes, but it can also be a reaction to poor diet, stress or bacteria growth in clogged pores.

The antimicrobial activity of Manuka honey, when used in combination with a low-pH product, is often marketed to fight acne.

Manuka honey could help keep your skin free of bacteria, expediting acne healing.
