Earthclinic.com is the absolute best remedy web site you will ever find. Look up "Sore Throat Cures" as an example. I am trying the Cayenne Pepper remedy next time I need it. Look up ANYTHING and you will get many, many opinions from actual experience. It can be a real time suck reading all of the entries but if you like this kind of thing it is fascinating! I do!
