Manuka Honey Eye Drops A Comprehensive Review


Manuka honey and its potential therapeutic benefits have gained significant attention in recent years. This unique type of honey has been found to possess various medicinal properties, including antioxidant, antibacterial, anti-inflammatory, and anti-nociceptive effects. These properties make it a promising candidate for the treatment of various ocular diseases, such as conjunctivitis, keratitis, blepharitis, and corneal injury. In this comprehensive review, we will explore the current research and discoveries regarding the use of manuka honey and its derivatives, such as eye drops, in the management of ocular diseases.

Antioxidant Properties of Manuka Honey

One of the key properties of manuka honey is its high antioxidant content, which is attributed to the presence of flavonoids and phenolic acids. These compounds contribute to the scavenging of free radicals and the prevention of oxidative damage. Manuka honey has been shown to protect against DNA damage, chelate ferrous ions, and inhibit the production of reactive oxygen and nitrogen species. These antioxidant effects are essential for maintaining ocular health and preventing the development of oxidative stress-related eye diseases.

Antibacterial Effects of Manuka Honey

Manuka honey exhibits potent antibacterial effects, primarily due to its high content of methylglyoxal (MGO) and hydrogen peroxide (H2O2). MGO is a naturally occurring compound found in manuka honey that has been shown to be effective against a wide range of bacteria, including multi-drug resistant strains. H2O2, on the other hand, is produced by the enzymatic activity of glucose oxidase and exerts oxidative damage on bacteria. These antibacterial properties make manuka honey a valuable therapeutic agent for the treatment of bacterial infections in the eyes.

Anti-Inflammatory Effects of Manuka Honey

In addition to its antibacterial effects, manuka honey also possesses potent anti-inflammatory properties. It has been shown to reduce the production of proinflammatory factors, such as interleukins and tumor necrosis factor alpha (TNF-α). These anti-inflammatory effects are crucial for the management of inflammatory eye diseases, as they help reduce inflammation and alleviate symptoms such as redness, swelling, and pain.

Anti-Nociceptive Effects of Manuka Honey

Manuka honey has also been found to have anti-nociceptive effects, meaning it can reduce pain perception. These effects are thought to be mediated by the modulation of peripheral nociceptive neurons or binding to opioid receptors in the higher centers of the central nervous system. Manuka honey has demonstrated analgesic effects in various pain models, including chronic pain conditions like osteoarthritis. These analgesic effects make it a potential treatment option for individuals suffering from ocular pain.

Therapeutic Applications of Manuka Honey in Ocular Diseases

Based on the current research, manuka honey and its derivatives, such as eye drops, have shown considerable therapeutic promise for the treatment of various ocular diseases. Honey has been used topically in the treatment of external ocular diseases affecting the cornea, conjunctiva, and eyelids. Its antibacterial, anti-inflammatory, and antioxidant properties make it effective in managing conditions such as conjunctivitis, keratitis, and blepharitis. Manuka honey eye drops have been found to improve symptoms and promote healing in these conditions.


In conclusion, manuka honey and its derivatives, such as eye drops, have shown significant potential in the treatment of various ocular diseases. The antioxidant, antibacterial, anti-inflammatory, and anti-nociceptive properties of manuka honey make it a valuable therapeutic agent for managing conditions affecting the eyes. However, further research is needed to translate these findings into clinical practice. Clinical trials and studies involving human subjects are necessary to determine the safety, efficacy, and optimal dosage of manuka honey eye drops. With continued research and development, manuka honey eye drops have the potential to revolutionize the treatment of ocular diseases and improve the overall health and well-being of individuals suffering from these conditions.
