For those of you who may have developed a sinus condition this winter, I HIGHLY recommend trying Neti Pot. Here is the best website I have found to clearly outline what Neti Pot is, and how to use it properly. http://www.jalanetipot.com/index.html Pay special attention to "Stage 2" of the cleansing process. THIS is what will get rid of any Upper Respiratory Infection you may have. Stage 2 cleaning is what really cleans all the gunk out. And here is a special tip for you. Add 1/3 dropper full of GOLDENSEAL liquid to your Neti Pot, in addition to the salt water, to add a holistic healing booster to the wash. Namaste - Alex
