White Crisco oil

My sister had eczema issues over 20 years ago. Went to doctor after doctor. Took their medicine and creams. Nothing. One day she was so frustrated she bought some white whipped crisco oil and slathered it on. Furs what? Itching was stopped and eczema and eczema was gone after a few more times. Sounds crazy but the truth. I had forgotten about that. I’m going to try it tomorrow. Put on a thin coat on a small area after a shower. Want to make sure it doesn’t cause a reaction.
