Sure. I started out with safflower until I found sesame then switched to that. I've now added coconut. someone here said they pull with two oils, one right after the other, so I've started doing that in the morning. sesame first for 20 minutes then coconut for 15 to 20. I also have added oregano oil to my waterpick and alternate with peppermint oil. I added oregano to the coconut this morning (intersting taste mixture. lol)just to give it another try. my first try I used too much and it burned a little.
