How do you use friar's balsam?

Friar's balsam is a solution of benzoin resin in alcohol. You should avoid using it on wounds. The usual use is to remove oils so that bandages will stick. Since the questioner wanted to know if it was suitable for use on a small ulcer on his toe - diabetic on insulin, the answer is not to use this. Visit your podiatrist as soon as possible and take this seriously. A family member had a similar wound and after learning the process from the doctor, we used saline to wash it daily with medical grade saline, covered it with a saline soaked material (can't remember the name), put mesh with an oil emersion on it and then wrapped it in gauze. Since his circulation was bad, a pressure sock went over that. It took awhile to heal, but there was no infection. Another friend self-doctored his and ended up with MRSA. Again, visit your podiatrist as soon as possible and take this seriously.
