Yes they do but please be aware of which type you are purchasing. If you are looking for castor oil for constipation please make sure to check the packaging and that it is drug tested for this purpose. They ALSO sell a type of castor oil NOT FOR CONSUMPTION that is used as a beauty product for skin and hair. I was looking for Castor Oil to start labor and they gave me the second one! Luckily I went back and asked someone else and they told me where to look. They were actually out of the castor oil laxative and I had to go to walmart instead!
