Mine says pure cold pressed hexame free and certified. I used 2 tablespoons today and it really cleaned me out. I took 2 tablespoons a couple of months ago after finishing humaworm and I passed some liver flukes. I only use it ocassionally internally. But I talked to some friends who said while they were growing up, if they got sick at all they were given castor oil internally. It was just used back then for whatever sickness they had. I was also told by another friend that she was given it now and then to rid parasites when she was younger. I sure would like to find out why people are so against taking it internally these days.
