The article describes the outcomes of a single-centre investigation on the use of OZOILE to improve the healing process in patients with chronic diabetic ulcers. This is a non-randomised interventional study which aims to assess the differences between two groups (total 200 patients) by evaluating healing time at 15, 30, 45, 60, 75 and 90 days. Pain assessment with VAS scale at 15, 30 and 45 days, biofilm test and tissue regeneration by histological evaluation were also taken into consideration. The outcomes show faster healing, reduced pain, control of local infection, aesthetically pleasing and qualitatively better healing. Our treatment strategy involves applying OZOILE detergent without rinsing, Ozoile spray oil and Ozoile cream followed by a non-adherent dressing (paraffin gauze). This integrated protocol shows a safe and effective treatment for diabetic chronic wound healing in a cost-effective manner. The group treated with the Rigenoma/Ozoile protocol demonstrated significantly superior outcomes compared to the control group, including accelerated healing, reduced pain levels, effective management of unpleasant odour, and high levels of compliance from both patients and surgeons. Overall, Ozoile markedly reduced healing time compared with standard care, with results robust across multiple analytical approaches.
