A few years back I read in this board a discussion about the product Zicam to reduce the severity of cold symptoms. I have used it twice now and either it is a great placebo or it works. Gross part now. I had some dripping down my throat and some chest congestion, but my nose never became stuffed or runny. Have to start using it when you first notice the symptoms. My coworker (the one who used it and not the one who didn't) swears by it too.
