Yes there is. More than likely everything will be fine. They used to use this stuff as a war bandage in the world wars because it does have antibacterial properties. The only thing to worry about is that one thing I posted. It may never happen, and I am not trying to alarm anyone. I just want folks to be aware if any kind of skin infection does occure for an unknown reason this might be something to check if LFS is used. More than likely it will almost never happen, but there is that 1 in a million chance it will. With my luck sometimes I will be that one out of a million, but if needed I do not think it will stop me from using it. At the moment I am trying to combat too high of a humidity. I will be adding more holes tomorrow.
