I believe we need to clean eczema from inside out. Applying potion/lotion/cream will only mask the pain and itch. If you want to remove eczema thoroughly you will need to remove offensive food such as gluten and probably diary, stop all offensive foods, you may go for food allergy tes to identify what are bad for you. Subsequently, Introduce good supplements of probiotics, wheatgrass and omeg etca. Be watchful as you might need to storm through some healing reactions or die-off reactions that can be awful.
I cured my eczema after a span of 18 months with some trial and error of many different types of natural approach. I did it successful since 2 years ago!
