I have been usung Pure Sunflower Oil for over a week to do the OP. Yesterday I managed to get to a Health Store and bought Cold Pressed Organic Sunflower Oil. I have OP twice, about 10mins each time and it's still very yellow. The first oil turned white when I did it. Will I change the time or swish and change. Any advice would be welcome as I really wish to pursue this. I want my son who suffers from hayfever to also try this.
