The widespread existence of unhealed wounds, ulcers, and burns has a great impact on public health and economy. Many interventions, including new medications and technologies, are being used to help achieve significant wound healing and to eliminate infections.

Therefore, to find an intervention that has both therapeutic effect on the healing process and the ability to kill microbes is of great value.

Honey is a natural product that has been recently introduced in modern medical practice. Honey’s antibacterial properties and its effects on wound healing have been thoroughly investigated. Laboratory studies and clinical trials have shown that honey is an effective broad-spectrum antibacterial agent.

This paper reviews data that support the effectiveness of natural honey in wound healing and its ability to sterilize infected wounds. Studies on the therapeutic effects of honey collected in different geographical areas on skin wounds, skin and gastric ulcers, and burns are reviewed and mechanisms of action are discussed. (Ulcers and burns are included as an example of challenging wounds.)

The data show that the wound healing properties of honey include stimulation of tissue growth, enhanced epithelialization, and minimized scar formation. These effects are ascribed to honey’s acidity, hydrogen peroxide content, osmotic effect, nutritional and antioxidant contents, stimulation of immunity, and to unidentified compounds.

Prostaglandins and nitric oxide play a major role in inflammation, microbial killing, and the healing process. Honey was found to lower prostaglandin levels and elevate nitric oxide end products.

These properties might help to explain some biological and therapeutic properties of honey, particularly as an antibacterial agent or wound healer. The data presented here demonstrate that honeys from different geographical areas have considerable therapeutic effects on chronic wounds, ulcers, and burns.

The results encourage the use of honey in clinical practice as a natural and safe wound healer.

PATHOPHYSIOLOGY OF WOUND HEALING

Every year in the U.S., more than 1.25 million people have burns and 6.5 million have chronic skin ulcers caused by pressure, venous stasis, or diabetes mellitus[1]. Diabetes represents a major impact on wound healing outcome. In 2004, according to the World Health Organization (WHO), more than 150 million people worldwide suffered from diabetes. Its incidence is increasing rapidly and it is estimated that by the year 2025, this number will double.

A wound is a disruption of the continuity of a tissue structure. Injury, by surgery or accident, causes destruction of tissue, disruption of blood vessels, and extravasation of blood constituents and hypoxia.

Wound healing is a complex, continual process that has three phases: inflammation, a proliferative phase, and tissue remodeling. Basically, wound healing is the result of interactions among cytokines, growth factors, blood and cellular elements, and the extracellular matrix.

The cytokines promote healing by various pathways, such as stimulating the production of components of the basement membrane, preventing dehydration, and increasing inflammation and formation of granulation tissue.

At the cellular level, monocytes infiltrate the wound site and become activated macrophages that release growth factors, such as platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF), which initiate the formation of granulation tissue. Macrophages have a key role in inflammation and repair[2]. It has been found that macrophage-depleted animals have defective wound repair[3]. We have found that macrophage transfusion accelerates wound healing in patients with nonhealing wounds[4]. Platelets facilitate the formation of a hemostatic plug and secrete PDGF, which attracts and activates macrophages and fibroblasts[2]. Re-epithelialization of wounds begins shortly after injury.

Epidermal cells at the wound margin begin to proliferate within 1 to 2 days after injury. On day 4 after injury, new granulation tissue begins to invade the wound gap and numerous new capillaries grow through the new stroma with its granular appearance. After migrating into wounds, fibroblasts begin the synthesis of the extracellular matrix[2,5].

The induction of angiogenesis was initially attributed to acidic or basic fibroblast growth factors, which are released from macrophages after cell disruption. Angiogenesis is the process of new vessel formation from an existing vasculature network.

Once the wound is filled with new granulation tissue, angiogenesis ceases and many of the new blood vessels disintegrate as a result of apoptosis[6]. Wound contraction involves a complex interaction of cells, extracellular matrix, and cytokines.

Vitamins C, E, and A, glucose, amino acids, antioxidants, fatty acids, proteins, water, and zinc are important for wound healing[7,8,9,10,11,12]. Administration of ascorbic acid protected mice against radiation-induced sickness and mortality, and improved healing of wounds after exposure to whole-body gamma radiation[13].

Low levels of antioxidants accompanied by raised levels of markers of free radical damage play a significant role in the delay of wound healing. In diabetic rats, reduced glutathione levels had a role in delaying the healing process[14]. Hydrogen peroxide is one of the mediators of healing responses[15]. Electrolyzed, strong acid aqueous solution irrigation may promote tissue growth in burn wounds[16]. Acidic media enhances wound contraction[7].

Nitric oxide (NO) has a wide range of physiological and pathophysiological activities, including the regulation of vessel tone and angiogenesis in wound healing, inflammation, ischemic cardiovascular diseases, and malignant diseases[17].

NO has been shown to increase microcirculatory blood flow, to kill infective organisms, and to have a significant effect in promoting wound healing[18,19,20,21,22,23]. Prostaglandins are mediators of inflammation and smooth-muscle stimulants, but inhibition of the prostaglandins and their precursors failed to alter the course of wound contraction[24].

Acute or chronic wounds can usually be covered by synthetic or natural dressings. Conservative methods of wound care include the use of standard wound dressings, management of underlying problems (such as hyperglycemia), debridement of dead tissue, restoration of adequate tissue perfusion, limitation of pressure at the wound site, and control of infection. These methods are successful in the majority of patients with acute or chronic skin wounds. However, large and life-threatening skin wounds may require the use of cultured, autologous, epidermal-cell grafts or biologic skin substitutes.

Recombinant PDGF has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of wounds. Furthermore, topical treatment of wounds is an important aspect of wound care. Proper selection of antiseptic or antimicrobial treatment for contaminated wounds is a cornerstone of wound care.

Five commonly used topical agents are 5% mafenide acetate, 10% povidone with 1% free iodine, 0.25% sodium hypochlorite, 3% hydrogen peroxide, and 0.25% acetic acid[25]. In addition, hyaluronic acid was used for wound dressing[26].

Basically, modulation of nutrition, underlining medical problems (such as vascular and neural diseases, diabetes, and infection), acidity of wounds, host immunity, cytokines, NO, or prostaglandins have a great impact on wound healing process.

HEALING PROPERTIES OF HONEY
Honey has long been documented as having healing properties[27,28,29]. Honey and sugar paste were associated with scarless healing in cavity wounds[30]. It has been reported that rabbit wounds treated with a topical application of honey showed less edema, fewer polymorphonuclear and mononuclear cell infiltrations, less necrosis, better wound contraction, improved epithelialization, and lower glycosaminoglycan and proteoglycan concentrations[31].

Furthermore, honey causes significantly greater wound contraction than controls, and it promotes the formation of granulation tissue and epithelialization of wounds[32,33,34,35,36,37]. Honey stimulates tissue growth, synthesis of collagen, and development of new blood vessels in the bed of wounds[38,39,40,41,42,43]. Intraperitoneal honey administration after an adhesion model in the cecum and terminal ileum of rats reduced postoperative adhesion[44].

HONEY AND WOUNDS
Generally, wound healing can be affected by endogenous (pathophysiology) and exogenous (micro-organisms) factors. The risk of wound infection increases as local conditions favor bacterial invasion and growth. Therefore, microbial colonization of both acute and chronic wounds is inevitable.

Many species of bacteria have been recovered from wounds, but Staphylococcus aureus is the most frequently isolated from wound pathogens[45]. In addition, Pseudomonas aeruginosa is an important pathogen in chronic wounds and burns; its presence has been demonstrated in numerous studies and has been found in one-third of chronic leg ulcers[46,47,48,49].

Infection with S. aureus and pseudomonads retards ulcer healing rates and, with pseudomonads and B-hemolytic streptococcus, reduces the success of skin grafts used for leg ulcers[50,51].

The widespread development of antibiotic-resistant bacteria is a challenging problem. Therefore, current interest is focused on an alternative to antibiotics and conventional therapies, such as honey, antimicrobial moisture-retentive dressings, essential oils and cationic peptides, topical enzymes, biosurgical therapies, and vacuum therapies.

In addition, unregulated inflammation caused by both micro-organisms and underlying abnormal pathophysiological conditions is a major factor associated with the process of healing in chronic wounds[52].

Many research works reported the use of honey for treatment of both wounds and infections[53,54,55]. Table 1 summarizes many papers that reported successful use of honey in wound healing. Honey with proven antibacterial activity has the potential to be an effective treatment option for wounds infected or at risk of infection with various human pathogens.

The medical literature on treating wounds with honey has been reviewed[56,57,58,59,60,61]. As a dressing on wounds, honey provides a moist healing environment, rapidly clears infection, deodorizes, and reduces inflammation, edema, and exudation. It increases the rate of healing by stimulation of angiogenesis, granulation, and epithelialization[62]. Table 2 demonstrates general effects of honey on the healing process.
