I don't know if oil pulling would help, or what causes them,but I do know how to get rid of them. I had one on my back for probably 10 years. My doctor called it a strawberry hemangioma, but it is probably the same thing. I read somewhere that hydrogen peroxide would get rid of moles. So, I took a Q-tip and put straight 35% peroxide on the strawberry once a day. It turned black and fell off within one week. I couldn't believe how simple it was. That was probably two years ago and it has never come back. I tried it on my 3 moles that I have and it just seemed to inflame them. I gave up on the moles, but maybe if I had persisted, it would have worked on them as well. Give it a try!
