I agree, also you have to pay attention to how you are pulling and swishing. The instructions says to do it without much effort or hurry.
The Process
Measure 10 ml. of refined sunflower oil or groundnut oil (approximately one table spoon) and without any great effort or hurry, wash and suck the oil inside the mouth like using a mouthwash. Never gargle or swallow the oil. Pull the oil through the teeth often and this oil will pull all the toxins from your body through saliva
I find that if I'm vigerous and swish like I'm trying to cause streams push through my teeth, like I would with mouthwash, it becomes more liquidy much quickly. But if I do it very slowly, pushing and pulling with very little effort, rolling the oil around my mouth very slowly it takes that much longer to liqify.
