Manuka honey is a type of honey native to New Zealand.
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 likely responsible for these antibacterial effects.
Additionally, manuka honey has antiviral, anti-inflammatory and antioxidant benefits.
In fact, it has traditionally been used for wound healing, soothing sore throats, preventing tooth decay and improving digestive issues.
Here are science-based health benefits of manuka honey.
1. Aid 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, all while maintaining a moist wound environment and protective barrier, which prevents microbial infections in the wound.
Multiple studies have shown that manuka honey can enhance wound healing, amplify the regeneration of tissue 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.
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. Promote Oral Health
To avoid tooth decay and keep your gums healthy, it is important to minimize bad oral bacteria that can cause plaque formation.
It’s also important not to totally wipe out the good oral bacteria that is 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 a high antibacterial activity is effective at inhibiting the growth of harmful oral bacteria like P. gingivalis and A. actinomycetemcomitans.
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.
3. Soothe 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, 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 causes 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.
4. Help Prevent Gastric Ulcers
Stomach ulcers are one of the most common illnesses affecting humans.
They are sores that form on the lining of the stomach, 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.
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.
5. Improve Digestive Symptoms
Irritable bowel syndrome (IBS) is a common digestive disorder.
Its associated symptoms include constipation, diarrhea, abdominal pain and irregular bowel movements.
Interestingly, 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 both IBS and ulcerative colitis, a type of irritable 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.
6. 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 quite 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 serious 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 in conjunction with antibiotic treatment.
Therefore, researchers concluded that manuka honey may play an important role in treating upper respiratory infections, especially in those with cystic fibrosis.
7. 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, which could expedite the acne healing process.
Also, given its anti-inflammatory properties, manuka honey is said to decrease inflammation associated with acne.
Is Manuka Honey Safe?
For most people, manuka honey is safe to consume.
However, some people should consult a doctor before using it, including:
People with diabetes. All types of honey are high in natural sugar. Therefore, consuming manuka honey may affect blood sugar levels.
Those allergic to honey or bees. Those allergic to other types of honey or bees may have an allergic reaction after ingesting or applying manuka honey.
Infants. The American Academy of Pediatrics does not recommend giving honey to babies younger than one due to the risk of infant botulism, a type of foodborne illness.
