@SarahGen-- I tried this nasal spray because my roommate convinced me that it has less than .1% capsaicin and that it wouldn't do me harm.
Boy was I wrong. This product made me feel like my nasal passage was on fire. If someone had sprayed pepper spray into my nose, I think that's what it would feel like.
I understand it's an all natural sinus treatment and some people might be able to tolerate the side effects for its benefits. But this is not a product that I can use, it causes more problems than my sinus infection.
