Manuka Honey

Manuka honey exerts its antimicrobial effects primarily through methylglyoxal (MGO), a unique compound that provides stable, non-peroxide antibacterial activity. Unlike standard honey, which relies on hydrogen peroxide, MGO remains active in biological fluids. It also contains defensin-1 and phenolic compounds that disrupt bacterial cell walls and inhibit biofilm formation, making it clinically validated for wound healing and H. pylori eradication (Evidence Level: C).

Manuka honey can interact with antidiabetic medications by elevating blood sugar levels. Patients taking insulin or oral hypoglycemics should exercise caution, as the glucose content in the honey may counteract the efficacy of these drugs. Diabetic patients are often contraindicated for internal use, and regular blood glucose monitoring is essential if use is necessary (Evidence Level: C).

For general internal health and digestive support, the standard adult dosage is 1 to 2 teaspoons daily. For external wound healing applications, the honey should be applied topically to the affected area as needed, often covered with a sterile dressing. Dosage may vary based on the MGO rating of the specific product used (Evidence Level: C).

Manuka honey is classified as unsafe during pregnancy according to specific safety profiles, primarily due to the risk of blood sugar elevation and potential microbial contamination. While often used as a natural remedy, pregnant women, particularly those with gestational diabetes, should avoid internal consumption to prevent glycemic complications (Evidence Level: C).

No, Manuka honey is strictly contraindicated for infants under one year of age due to the risk of infant botulism. Honey can contain *Clostridium botulinum* spores which an infant's immature digestive system cannot neutralize. Ingestion can lead to severe illness, including muscle weakness and breathing difficulties. It is safe for children over one year and adults (Evidence Level: A).
