Hmmm... so I read the" don't breathe the stream" part of the instructions and started wondering how safe this is to use. I Googled "oxalic acid symptoms" and according to the CDC, it can be an irritant if left on the skin. I would proceed with caution. That said, it may still be safer than the hair dyes from the store!!! Heaven only knows what's in them.
