It's not toxic. I saw an article about Turkish research of its properties compared to stitching in children after circumcision - works and heals better than stitching.

Found some in a plastic bottle here: http://www.healthypets.com/nexliq15ml.html
Though, that one is expensive. It must be cheaper somewhere.
I'm from Russia, and I remember using such a glue all the time when I was young. It was something very affordable for 2oz bottle.

It seems to me, the topic must be renamed to "GLUING BACK BODY PARTS" now Maybe better to open a new thread?
