Steve Harris, M.D. The above doctor's quote suggests that Cyanoacrylate adhesives (Super Glue, Krazy Glue) may be used to cover cuts. He suggests that it is non-toxic, but I am skeptical. I heard of this before and wanted to recommend this to someone who cut their finger and plays a stringed instrument. Any musician who plays a stringed instrument knows how hard it is to play with a cut finger. Any toxicity to our body or adverse health effects?
