For all who are doing the Natural Healing Program on this forum, make use of castor oil packs over the liver and intestines. Read up on what Edgar Cayce said and did with castor oil. A wonderful healing modality. The packs will make all the difference in the world for healing. http://WWW.heritagestore.com is a good place to get the castor oil. http://WWW.vitacost.com carries the good stuff, too. I do believe there is an expiration date on this stuff, so getting more than 2 quarts at a time isn't recommended, unless you will use more. It's good for about 2 years on the shelf. The packs are kept in the refrigerator overnight and thrown away at least after 30 days.
