The sample at the end of the study will only be obtained if the wound is still open. In addition, at the beginning and at the end a blood sample of 5cc will be taken to measure levels of inflammatory markers and oxidative stress in blood. These samples will be taken in the same Specialty Clinic of the Regional Hospital of Talca, but they will be transferred to be processed in the Clinical Biochemistry Laboratory of the Faculty of Health Sciences and the School of Medicine of the University of Talca. .

During the last care / healing that the nurse does to the patient, you will be asked to complete a survey with questions to collect personal opinions about the effect of topical propolis. Benefits: It has been described that the topical application of Propolis can improve the healing of human diabetic foot ulcer.
