Wound healing is a complex and regulated process that is critical in maintaining the skin barrier function. The numerous disease processes can affect the events involved in wound healing, resulting in chronic, non-healing wounds. These would subject them to significant discomfort and distress and drain the medical system resources enormously. A chronic wound can be defined as that does not heal in an orderly set of stages and in a predictable amount of time or within three months. They remain in the inflammatory phase for too longand never heal or may take years.3,4 Chronic leg and foot ulcers occur in many adults with diabetes, chronic venous insufficiency, arterial disease, prolonged pressure, or neuropathy.5 Chronic ulcers may last for 12 to 13 months and even recur in 60-70% of cases. They cause loss of function and decreased quality of life and significant morbidity.6,7 These chronic ulcers are predominantly seen in elderly, becoming more prevalent and more difficult to treat and are associated with high treatment costs. So wound care has become essential in these ulcers, and surgical debridement and dressings are the corners stones. Many wound dressings like gauge, films, hydrocolloids, gels, foams etc. were developed to both protect the healing wound from infection and to promote the healing process.1 Placental extract gel is a rich source of various peptides, amino acids, nucleotides, PDRNs and carbohydrates, which are believed to support the healing process.9 Application of placental extract preparation increases collagen synthesis, increases tissue protein, accelerates neoangiogenesis, and epithelialization.10 It has an immunotropic effect and causes the release of Epidermal growth factor, Fibroblast growth factor at the tissue level. It also reduces surrounding tissue inflammation and oedema and reduces microbial burden.11 Its application accelerates healing because of amino acids, nucleotide and vitamins that improve healing.
