[YEA] I was reared from childhood, being given a tablespoon Castor Oil montly for cleaning out the colon, and also removing or killing parasites. The Castor bean has drawing properties, and does work well for drawing purposes. It has been used for so many remedies for many years, and yes, can be used as a purgative. But it also draws out impurities from the cellular tissue. I have also used it to purge of gall stones from Gall bladder. I simply mixed it with grapfruit juice, in order to get it down.
