Unusual cure for sore throats

This is bad time of year for my throat. Because I live in Austin, one of the allergy capitals of the world, and am especially prone to sneezing, itching, and general snottiness this time of year, my throat always feels swollen and gross.

But, according to the folk-remedy site Earth Clinic, the cure may be as simple as a little cayenne pepper. Says the site, "This remedy works when antibiotics do not and is excellent for those weird sore throats that don't seem to go away after 4 weeks (the ones that possibly lead to chronic fatigue syndrome)."

As noted by Lifehacker, there's over a hundred comments from readers who think this is highly effective. Have you tried this? Did it work for you?
