From what I understand, ezema is an allergic reaction. Instead of trying to externally treat his ezema, you should try eliminating whatever is bugging him from your diet. My six month old son has some serious food intolerances so I've had a crash course in this type of thing the last couple of months. His big triggers are soy, dairy, eggs, caffeine and chocolate. Amazingly enough soy is the one thing that is really, really hard to avoid because it is in virtually everything processed. So I'm on a mostly "whole" food diet. I eat lots of oatmeal, grilled meat, rice, potatoes, veggies and fruit. And beans. So I have a really healthy diet and I've lost close to 20 pounds without even trying. And my son is doing SO well. All of the stomach problems and skin rashes he was having have completely cleared up. When I first started my elimination diet, I also eliminated fish, shellfish, nuts and citrus. My son's pediatric GI doctor said that dairy, soy, eggs, nuts, caffeine, fish, shellfish, chocolate and citrus and the most common allergens... I've been able to add back small amounts of nuts, citrus, fish and shellfish without a problem. I'm thinking about trying eggs again here soon. I KNOW he reacts to soy so I'll be avoiding that for at least 6-12 more months. And since he can't have dairy or soy, obviously formula is out of the question... They have hypoallergenic ones but they aren't truly hypoallergenic, they are just less allergenic. And they are close to $30 a can.
But, anyway, you might want to take a serious look at your diet and explore the food allergy/intolerance thing. Ezema is miserable and it would be better to find out what is triggering it and elmininate it instead of trying to treat it.
