During one of my freelance stints, I was asked to make a series of animated GIFs for a medicated cream called Zostrix. This product's key ingredient is Capsaicin, which is derived from peppers. Similarly, I built the template for the animations used on the Sinus Buster website. Sinus Buster also uses Capsaicin. So imagine squirting hot chilli pepper into your nostrils. It might really do the trick!
