Castor Oil needs to be cold pressed in order to have it be useful in a castor oil pack... if its not cold pressed, the useful ingredients in the oil won't have made it through the manufacturing process. I read an article that talked about a study of castor oil packs and t lymphocyte production - everyone in the study did amazingly well with the packs, except for 2 people- and it was later determined that those 2 didn't use cold pressed oil.
