A Cure for Sinus Infections?

American Drink has a recipe for Horseradish-Infused Vodka.
It makes terrific Bloody Marys of course, but it's also a kick in the pants straight. Apart from zinging your tongue, horseradish really gets into your sinuses. 
I wouldn't put it in a neti pot, but it might be worth a shot on a cold winter night.
