Are there any at home remedies for curing eczema?

Protect. Avoid things that make you break out, soaps & wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot. Use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.
Moisturizers. There is no cure for eczema. Roughly 85% of kids grow out of eczema. The best way to reduce eczema flares is to moisturize. Eczema skin has reduced ceramides, so i generally recommend lotions containing ceramides (such as cerave), and then apply a "sealant" lotion over it (eg. Cetaphil). Moisturize at least twice daily.
