Query: Hmmmm, Not sure

I got this product from another store. And it will get rid of odor. But everytime I have used this product I always get headaches and feel dizzy. A couple times I had heart palpitations.I noticed it also leaves a residue on the items. Be very careful with leather products and simulated leather products becausethis product and mix with leather and simulated leather in such a way that will give off toxic fumes...and when this happens you will have to throw the item away.I had this happen to my simulated leather purse.
