I would think the same thing. Assuming the external product(s) work, which appears to be the case, the FDA is probably looking to see if there is any irritation or harmful side effects. In which case I wouldn't think every different type of external sore/wound/etc. would require a separate human trial. Maybe something like burns might require an additional trial. But I wouldn't think a lot. I don't think we're talking Oprah's tray after she goes through the buffet line.
