Why do you want to use it? Melafix contains Pimenta racemosa, which is an extract of the Bay Rum Tree. Some studies have shown it to have some antiinflammatory properties (kind of like fish motrin) but it's effectiveness as an anti-bacterial or anti-fungal are not quite as proved. Depending on what you're treating, IMHO, you may be better off using an appropriate antibiotic rather than relying solely on Melafix.
