"Is Oil Pulling Dangerous?
I see no real way that oil pulling could be dangerous. After all, it's just vegetable oil. Assuming you don't choke on it, oil pulling is probably completely harmless.
Does all this mean that oil pulling is a scam? Maybe not. Most of the oil pulling web sites we looked at seem more interested in attracting advertising than hard-selling something to their readers. More likely, it means that well-meaning individuals are putting stock in an unproven pseudo-therapy. Their only real "crime" is passing along bad information. But you now have the tools to understand why oil swishing can't "pull" toxins out of your blood and the information to make up your own mind about oil pulling."
this article says nothing. it has no substance whatsoever. it only appears to say something. but it "is probably completely harmless." then it even backtracks on bad motives by saying, "More likely, it means that well-meaning individuals are putting stock in an unproven pseudo-therapy." there is only one logical conclusion that can be drawn from these statements is that the well meaning people are not doing anything harmful to themselves or others and that their only motivation can be to help others. in order to have this motivation, one must be convinced one is correct about the subject. this means they must have tried it themselves in order to ensure they done hurt others with their advice. this means it must do the things they say they have done because they are giving personal testimonies.
thanks for the confirmation of what we already KNOW.
