Okay? Kinda.
Anything made for use on the body is going to be body-safe. It's not going to poison you or cause serious juries or anything. However, it might cause a burning sensation or other irritation, and if there's glycerin in it, it might act as a stimulant laxative. It's also not very effective as lube in the first place, especially when you add water to it (like spit or natural anal juices) which will just make it clot and separate.
Just buy some lube. Any grocery or drugstore. Very cheap and will work much better.
