I’ve never had any issues but then again I’ve only used it on fairly minor wounds. It is recognised as a household product that can be used as a styptic. I’ve also used it when our sheep have broken a horn off at the base so it will stop a major bleed if need be.Is that not likely to cause granulation in the wound?
I always go for fabric plasters they’ll stay on through at least 2 showers, whereas plastic ones seem to come off at the first hint of water.I always find plasters peel or slide off so I carry medical tape with my plasters now and hold them on with a couple of wraps of that. For deepish cuts I use kitchen towel and a rubber band. I did cut my finger to the bone a couple of years ago and just used kitchen towel and gaffer tape on that which was perfectly adequate. 6 hour wait in A&E and 8 stitches for that one.
