I had most of the bumps disappear within three days of oil pulling, with safflower and coconut. However, the red spots from them remained. I think that eventually they'lll go away as things heal. It just seems the hemp works faster on the red. I have noticed, if you stop oil pulling, the bumps come back. I don't know if you keep up the oil pulling for a long time and the bumps have been gone for a long time that maybe eventually they won't come back. One can only hope.
But like I said, hemp is expensive. It was near $16 for a 8.5 oz. bottle, but that was full retail from a health food store.
