Manuka Honey for Heart Health


Honey is not just a sweetener; it also offers a wide range of health benefits. One type of honey that stands out is Manuka honey, known for its potent antibacterial and anti-inflammatory properties. In this article, we will explore the unique qualities of Manuka honey and its potential benefits for heart health.

What Sets Manuka Honey Apart?

Manuka honey is primarily found in New Zealand and Australia, where bees collect nectar from the Manuka tree to produce this distinctive honey. The indigenous populations in these regions have long used the Manuka tree for its medicinal properties. With the introduction of European honeybees, Manuka honey became a significant source of nectar for honey production.

Unlike other types of honey, Manuka honey exhibits a higher level of antibacterial properties. It contains hydrogen peroxide, which can inhibit the growth of bacteria by disrupting their cell membranes and DNA. Additionally, Manuka honey contains a unique compound called methylglyoxal (MGO), derived from the Manuka tree, which exerts antibacterial effects independently and is unaffected by the digestive process.

The Antimicrobial Potency of Manuka Honey

A study published in the International Journal of Clinical Pediatric Dentistry in 2018 found that Manuka honey, due to its high content of MGO, exhibits antimicrobial activity that is 100 times stronger than regular honey. MGO interrupts cell division, arrests growth, and specifically degrades bacterial DNA.

Manuka honey has a minimum inhibitory concentration (MIC) value of only 1 percent against specific bacteria, demonstrating significantly stronger inhibitory effects than other varieties. It has been shown to inhibit the growth of multidrug-resistant bacteria, commonly known as superbugs, in in vitro experiments.

Health Benefits of Manuka Honey for Heart Health

1. Wound Healing

Manuka honey is widely used to produce dressings and ointments for treating various conditions, including diabetic wounds, venous ulcers, burns, acne, eczema, and psoriasis. Its antibacterial properties help prevent infection and promote the healing process.

2. Gastric Ulcers

Manuka honey can inhibit H. pylori, the bacterium responsible for gastric ulcers. It is used in treating bacterial gastroenteritis and shows promising results in reducing ulcer symptoms.

3. Sore Throats

Manuka honey demonstrates antibacterial properties against a range of oral bacteria, offering bactericidal effects comparable to antimicrobial mouthwashes. It can be used as a gargle or mixed with warm water and slowly consumed to alleviate sore throat symptoms.

4. Anti-Inflammatory Effects

The phenolic content of Manuka honey contributes to its anti-inflammatory and antioxidant activities. It has been shown to be effective in reducing inflammation in conditions such as ulcerative colitis, which is characterized by high levels of inflammatory factors and oxidative stress. Animal studies have demonstrated its potential in preventing and treating this condition.

5. Potential for Cancer Treatment

Studies are currently investigating the efficacy of combining Manuka honey with chemotherapy drugs for cancer treatment. The anti-inflammatory and antioxidant properties of Manuka honey may help enhance the effectiveness of chemotherapy and reduce its side effects.

Tips for Choosing Manuka Honey

Not all Manuka honey is the same, so it’s important to choose the right product. Look for honey derived from certain species of Manuka trees that produce high levels of chemical compounds that can convert into MGO.

Check the label on the honey packaging for the Unique Manuka Factor (UMF) rating. A UMF rating of 10 or higher indicates a higher level of active benefits offered by Manuka honey.

Choose Manuka honey with an MGO content greater than 250 mg/kg for maximum bioactivity. For nutritional supplementation, products with MGO content below 250 mg/kg can be considered.

Limit the daily intake of honey to 15 to 20 grams, roughly equivalent to one tablespoon, to avoid excessive sugar intake. Consult a doctor if you have concerns about blood sugar levels or diabetes.


Manuka honey offers unique health benefits due to its potent antibacterial and anti-inflammatory properties. Its high content of MGO makes it a powerful antimicrobial agent, with potential applications in wound healing, gastric ulcers, sore throats, and heart health. By choosing the right Manuka honey with a high UMF rating and MGO content, you can harness the full range of active benefits offered by this remarkable honey. Incorporate Manuka honey into your daily routine and experience the potential health benefits it has to offer for heart health and overall well-being.
