Pulling oil is an ancient technique that pulls toxins (ama) from your mouth which in turns, reduces inflammation in the body thereby helping to treat and prevent disease. At first it seems like an odd thing, but when you think that over 600 types of bacteria live in the mouth, you soon realise that this is extremely important to draw out toxins.
Buy some high quality extra-virgin cold pressed coconut oil. This isn't cheap but it is great for cooking, massage and many other uses as well as pulling, and is particularly good for pulling due to the great taste.
The technique is to take a spoonful and swish it around your mouth for twenty minutes. The oil will probably be solid at first - especially if you live in a cold climate, but will soon dissolve into a liquid once warmed up.
The best time to do this is first thing in the morning and before drinking any water. You have the largest amount of toxins in your mouth at this time and once you drink, they will all be taken back into your body. This is why using a tongue scraper is also a particularly good idea - and when you see the white gunk that comes off there you will never go back!
The most important thing to remember is to try not to swallow any of the oil. It will collect up all the bacteria in your mouth and this is what you are trying to get rid of, so once you've swished it around, in and through your teeth, spit it out into a bin. I wouldn't advise spitting it into a sink since you can easily block up pipes that way.
The positive results from this daily morning practice are whiter teeth, better complexion, the removal of toxins and significantly better oral hygiene.
I noticed the first time I did it that initially I had headaches, pimples and a mouth ulcer but these did not last too long and were part of the purification of freeing my system from toxins.
You can use other oil, such as good quality extra virgin olive oil, for this but I think coconut oil is the most pleasant and effective.
Oil pulling is definitely one of the ways to boost our immune system. WHen done with gingelly or sesame seed oil is also known to work wonders similarly as well as allegedly easing arthritis symptoms and rheumatic aches in marginally heavy or old people. It also serves as a natural coolant for the body, when applied and massaged in to the skin, before taking a bath in warm water bath.
I tried oil pulling years ago and I know of it's many benefits. My teeth absolutely looked whiter, but doing the practise was not enjoyable for me. Actually I found it pretty gross and eventually gave up.
