started oil pulling 20 dec 07. have used olive, safflower, hemp, sesame, oils. also i have had others try the pull also. so far noticed from safflower are teeth got white, gums felt firmer, sinus's cleared, allergies diminished. from hemp i got sleepy. others that tried olive it immediately raised their mood levels and depression. gout pain eased with only one olive oil pull. i also add a couple of drops of peppermint in the tablespoon to kill the germs and open the sinus's too. sesame did not get any immediate results maybe because it is toasted . all in all everyone i have told that used it have been very happy with the results. only problem is trying to explain to them how it works. so i tell them that it works like oil in an auto engine that catches dirt and when you change the oil the dirt comes out. my nephew that is a plumber in oregon relayed that to me when i was trying to tell him to do the pull he automatically understood how the process could work. in his profession he stated that plumbers work with oil and water all of the time. smart nephew i have.
