I think it's a bit of a stretch to say it is entirely non-toxic:

Anaphylactic shock is the fucking scariest thing i have lived, it was twice some years ago, it was because i´m allergic to some type of penicillin and trust me; i´m lucky to be alive, first you feel itches for all the body, crazy itches how get higher, them you slowly can´t breat, thats gradual at the point you are sofocating, let me tell you that you have only minutes to get and addrenalin inyection because your lungs are contracting and finally you pass out. The two times i was inconscient when i get the addrenalin, so its like you are vanishing slowly and then when the addrenalin makes effect your lungs start to work again but they expand to fast that hurts so bad and you get back of that deadly sleep....a damn fucking scary experience i dont wish that even my worst enemy
