Why would any oil pulling website be paying people to promote them? What are these websites? Doesn't seem to be much money making potential there since they all tell you to use plain old oil from any grocery store!
I have been pulling for 6 months and have avoided catching countless illnesses while people all around me are sniffling, sneezing and hacking up phlegm. I cleaned up my diet a few years ago, exercised, took EFAs, etc. but I still got sick every winter. Oil pulling is the only thing that I did differently last winter--tada, no more illness (save for a couple days of very light symptoms).
