Ozonated oil in wound healing: what has already been proven?

Acute or chronic inflammatory reactions aim to control lesions, resist to pathogens attack and repair damaged tissue. The therapeutic administration of ozone known as ozone therapy appears as a possible treatment for tissue repair, as it promotes the healing of wounds. It has bactericidal, antiviral and antifungal properties and has been used as a therapeutic resource to treat inflammation. The objective was to carry out an integrative review regarding the use of ozonated oil in acute and chronic inflammations. The keywords “ozone therapy,” “inflammation” and “ozone” were used in the Portuguese, Spanish and English languages. The paper selection was based on inclusion and exclusion criteria. In total, 28 articles were selected. It has been seen that ozonated oil is effective in healing cutaneous wounds. The beneficial effects are due to the healing of wounds, due to the reduction of microbial infection, debridement effect, modulation of the inflammatory phase, stimulation to angiogenesis as well as biological and enzymatic reactions that favor the oxygen metabolism, improving the wound cicatrization. In addition to promoting healing, ozonated oil reduces symptoms related to skin burns, prevents post-lesion hyperpigmentation, and reduces the pain of aphthous ulcers. Therefore, ozonated oil represents an effective and inexpensive therapeutic alternative that must be implanted in the public health system.
