Deepak Chopra mentioned in a couple of his books that if you rub sesame oil all over your body before showering, the body will absord far more usable oil than a person could possibly ingest at one time. I also do the body rub and I find that if I leave the oil on for 20 minutes that I will become light-headed and things get blurry. I know then that I best get into the shower. Maybe that is what happened to you.
That full body rub with the sesame sure feels good......
