Review of animal models used to study effects of bee products on wound healing: findings and applications

Non-healing wounds are associated with high morbidity and might greatly impact a patient’s well-being and economic status. For many years, scientific research has focused on developing and testing several natural and synthetic materials that enhance the rate of wound healing or eliminate healing complications. Honey has been used for thousands of years as a traditional remedy for many ailments. Recently, honey has reemerged as a promising wound care product especially for infected wounds and for wounds in diabetic patients. In addition to its proposed potent broad-spectrum antibacterial properties, honey has been claimed to promote wound healing by reducing wound hyperaemia, oedema, and exudate, and by stimulating angiogenesis, granulation tissue formation and epithelialisation. Several animal models, including large animals, dogs and cats, and different species of laboratory animals have been used to investigate the efficacy and safety of various natural and synthetic agents for wound healing enhancement. Interpreting the results obtained by these studies is, however, rather difficult and usually hampered by many limiting factors including great variation in types and origins of honey, the type of animal species used as models, the type of wounds, the number of animals, the number and type of controls, and variation in treatment protocols. In this article, we provide a comprehensive review of the most recent findings and applications of published experimental and clinical trials using honey as an agent for wound healing enhancement in different animal models.
