I have been doing Oil pulling for one month. I read that it helps hormonal problems, but i didnt think it would erradicate my cramps. But after pulling for 1 month, my menstrual cramps and other pms associated problems are almost non existant. For the first time in years i was able to spend the first day of my course like any other normal day, not bent over in agonizing pain. And my skin has cleared up as well. My sister started OP and after a week she had the same outcome!! No Cramps. I will continue to OP and wait to see all the benefits from "pulling" the toxins out of my body. I also find that it is VERY!!! important that you brush your teeth and drink a large glass of water after pulling because you are releasing these poisonous toxins and you want to get them out.
