I don't have any knowledge of taking caster oil internaly ,,but if it works for you that is great , you may have discovered another type of treatment that can help other people , I am only aware of the castor oil packs and my own reaction to them ,I started using them because of my reaction to many other natural treatments that had a moderatly bad reaction afterwards , I still can't take any suppliments in the day time only in the evening that is when my body let me do so with out feeling bad afterwards , I still don't understand why ,but just glad to be able to take them. after about 15 min with casteroil packs I can feel the castor oil working its way into my body doing its cleansing thing , but do not feel the positive effects untill the next day , I am doing a caster oil pack 3 times a week for now , still having mecury detox sysmtoms ,but the cleanses help make detox more tolerable , it is very important to keep the pathways open to allow the toxins to exit the body much easier , I will try the walnut hull next week to kill the parasites I have also been taking olive leaf extract for the past two months , it is supposed to help with parasites also , don't want to start any thing else this week ,got front row tickets to john mellencamp next week , don't want to chance feeling bad for the concert
