Manuka honey is a unique type of honey that is native to New Zealand. It is produced by bees that pollinate the Manuka bush, scientifically known as Leptospermum scoparium. Unlike traditional honey, Manuka honey stands out due to its exceptional antibacterial properties, making it highly sought after for its medicinal benefits.
The Grades of Manuka Honey
Manuka honey is graded based on its level of potency and antibacterial activity. The grading system is known as the Unique Manuka Factor (UMF), which measures the presence of methylglyoxal (MGO), the main active ingredient responsible for the honey’s antibacterial effects. The UMF rating ranges from UMF 5+ to UMF 20+, with higher ratings indicating higher potency.
Recognizing Antibacterial Activity and Potency
The antibacterial activity of Manuka honey can be recognized through laboratory tests that measure the honey’s ability to inhibit the growth of bacteria. These tests assess the honey’s Minimum Inhibitory Concentration (MIC), which determines the lowest concentration of honey needed to inhibit bacterial growth.
Potency, on the other hand, is determined by the honey’s UMF rating, which indicates the level of MGO present in the honey. Higher UMF ratings signify greater potency and antibacterial activity.
Understanding the Main Active Ingredients: Methylglyoxal, Leptosperin, and Dihydroacetone
Manuka honey contains several active ingredients that contribute to its health benefits. The main active ingredient is methylglyoxal (MGO), which is responsible for the honey’s antibacterial properties. MGO is formed from dihydroxyacetone (DHA), a naturally occurring compound found in the nectar of the Manuka bush. The conversion of DHA to MGO occurs during the honey’s production process.
Leptosperin is another compound found in Manuka honey that serves as a marker for its authenticity. It is unique to Manuka honey and helps distinguish it from other types of honey. The presence of leptosperin in Manuka honey confirms its origin and purity.
Dihydroacetone (DHA) is a precursor to MGO and plays a crucial role in the formation of MGO in Manuka honey. The level of DHA in the honey can also be used to determine its potency and antibacterial activity.
Measuring the Active Ingredients
The active ingredients in Manuka honey, such as MGO, leptosperin, and DHA, can be measured using various laboratory methods. These methods include:
High-Performance Liquid Chromatography (HPLC): This technique is used to measure the concentration of MGO in Manuka honey. It involves separating the components of the honey and quantifying the amount of MGO present.
Nuclear Magnetic Resonance (NMR) Spectroscopy: NMR spectroscopy is used to measure the concentration of DHA in Manuka honey. It allows for the identification and quantification of DHA, which is important in assessing the honey’s potency.
Health Benefits of Manuka Honey
Manuka honey offers a wide range of health benefits due to its unique properties. Here are some of the scientifically supported health benefits of Manuka honey:
1. Aid Wound Healing
Manuka honey has been used for centuries to treat wounds, burns, and sores. Its antibacterial and antioxidant properties help create a moist wound environment and protect against microbial infections. Studies have shown that Manuka honey can enhance wound healing, regenerate tissue, and reduce pain in patients with burns and non-healing wounds.
2. Promote Oral Health
Manuka honey has been found to have antibacterial effects against harmful oral bacteria associated with plaque formation, gum inflammation, and tooth decay. Research has shown that chewing or sucking on Manuka honey can reduce plaque and gingival bleeding. Unlike refined sugar, Manuka honey does not contribute to tooth decay and may actually promote oral health.
3. Soothe a Sore Throat
The antiviral and antibacterial properties of Manuka honey can help reduce inflammation and attack the bacteria that cause sore throats. It also provides a soothing effect by coating the inner lining of the throat. Manuka honey has been found to decrease Streptococcus mutans, a bacteria responsible for sore throats. It can also help alleviate the symptoms of mucositis, a common side effect of radiation and chemotherapy.
4. Help Prevent Gastric Ulcers
Manuka honey may help treat gastric ulcers caused by Helicobacter pylori (H. pylori), a common bacteria responsible for stomach ulcers. Research has shown that Manuka honey has antibacterial effects against H. pylori and can be used as an adjunct treatment. It may also prevent alcohol-induced gastric ulcers.
5. Improve Digestive Symptoms
Regular consumption of Manuka honey has been found to improve antioxidant status and reduce inflammation in individuals with irritable bowel syndrome (IBS) and ulcerative colitis. It has also been shown to attack strains of Clostridium difficile, a bacteria that causes severe diarrhea and inflammation of the bowel.
6. May Treat Symptoms of Cystic Fibrosis
Manuka honey has been shown to fight bacteria that cause upper respiratory infections, which are common in people with cystic fibrosis. It inhibits the growth of bacteria such as Pseudomonas aeruginosa and Burkholderia spp. and may play a role in treating upper respiratory infections in individuals with cystic fibrosis.
7. Treat Acne
Manuka honey’s antimicrobial and anti-inflammatory properties have made it a popular remedy for acne. Its ability to fight bacteria and reduce inflammation may help expedite the healing process of acne. While further research is needed, studies have shown similar benefits with kanuka honey, which has antibacterial properties similar to Manuka honey.
Is Manuka Honey Safe?
For the majority of people, Manuka honey is safe to consume. However, there are a few exceptions:
People with diabetes should be cautious due to the high natural sugar content of all types of honey, including Manuka honey. It may affect blood sugar levels.
Those allergic to honey or bees should consult a healthcare provider before using Manuka honey, as they may experience an allergic reaction.
Infants under the age of one should not be given honey due to the risk of infant botulism, a type of foodborne illness.
In conclusion, Manuka honey offers numerous health benefits, particularly in wound healing, oral health, sore throat relief, gastric ulcer prevention, digestive symptom improvement, cystic fibrosis symptom treatment, and acne management. When used in conjunction with conventional therapies, Manuka honey can be an effective treatment strategy. However, it is important to consult a healthcare provider before using Manuka honey, especially for individuals with diabetes or allergies.
