Eczema: It is unclear exactly what causes eczema but from a holistic stand point, it's an imbalance in the immune system over acting to an unknown substance that we had introduced into our body through our gut. If we heal the gut a lot of our peculiar ailments will disappear. A good quality probiotic is a good start. All disease starts in the gut, according to hippocrates.

Itch that rashes: In eczema, the 'hallmark' is the itch that rashes, where there is a cycle of itch-scratch that perpetuates this condition. Other skin conditions may mimic eczema, so evaluation by your doctor or dermatologist is warranted. Atopic individuals have a personal or famiy history of asthma, allergic rhinitis, nasal polyps, or "sensitive" skin.
