Well...it's flavored so I am guessing they meant it to be swallowed in small amounts but because of some of the ingredients, I wouldn't even put this stuff near my no nos. Tetrasodium EDTA, Methylparaben, and Imidizolidinyl Urea aren't really the safest ingredients but it shouldn't kill you.
Sliquid has a flavored lube line (sliquid swirl) which is 10000x safer than this stuff.
