Sp,
Have you even tried it? Are you just on a bandwagon of whoever sounds good? Oilpulling has much more effect than placebo.
MH,
Have you tried oilpulling to state it does nothing? Because it doesn't come from the Amish and it is an Ayurvedic tradition, is that why it is not effective?
Everything that is good and right in this world is not solely from the Amish.
