SL,
Here is a link showing and explaining the Neti Pot. It has its origins in Indian (Eastern) medicine I believe.
www.netipot.com/usa/index.phpThe instructions do say not to use tap water...I am sure that it just a precaution, being that tap water is treated...but anytime you are flushing water up into your sinuses...why not be sure it is the purest possible right? Also, this reduces the chance of irritation from the additives. (chlorine/fluoride)
Anyway, I have used one on occasion for years, and never had a problem. Bobbyanne will be just fine! :)
