That's a lot, but shouldn't hurt her. I've heard of some people who have taken up to 15 tablespoons a day for short periods of time. If you take too much, you'll get nauseous and heavy-hooo. Does she eat very much in addition to the oil? That much should suppress her appetite. But usually about 2 to 3 tablespoons per day is recommended. A little more if you are very heavy.
