I am not a healthcare professional, but definitely someone who is very interested in herbs and supplements of all kinds. So like Peter said, definitely always consult your doctor before trying anything new!
From the (minimal at this time) research I've done though, it does seem like it could potentially be beneficial. I know we naturally have ceramides in the skin, but as we age, we lose a lot of them (much like collagen), so supplementing could be helpful. I know they are also found in some foods - like sweet potatoes, soy, wheat (not gluten free friendly for those that have to avoid it like me!), rice, corn, and I'm sure some others.
Have you decided to give it a shot since posting this? Keep us posted - I'm interested to learn more and will definitely be doing some more research on this! Thanks for posting this. -Nina (AtopicDermatitis.net Team Member)
