Excellent answer from Kokinow. It definitely can be used, however, it is a chemical and (my opinion) only use on small cuts not requiring stitches. To clean the wound, rather than hydrogen peroxide, soak in as warm water as you can stand, with table salt added. Stir to semi-dissolve. It's still the best "old wives tale" (my opinion) to draw out infections and cleanse a wound before it gets an infection. Especially good for hangnails. Use enough salt to liberally cover the bottom of the container you're using.
NO! That is not wise because you never want to put anything that is not sterile on an open cut or wound because of bacterial contamination & the last I checked the tip of a superglue tube is NOT sterile. The liquid bandage drs or hospitals use is sterile. They do sell nice little bandaid called butterfly that will bring a cut together & help in healing.
