Sort of works some of the time
I regularly have sinus headaches.  I take these at least once each day, sometimes twice.  Sometimes, it seems to help.  I have tried many different natural remedies, and many different products, looking for something better, but with no success.  By comparison, this product at least has some value.  I wish that this product had 10X the amount of horseradish, as I think that would likely make it more effective for me.
