Q. Eczema tic itching leads making his skin reddish and abraded. My brothers eczema is very vulnerable to allergens. In spite of steps taken to eliminate this we have not succeeded much. His medicines do not help him. They cannot cure this immune disorder. They have started showing some side effects. His fight for eczema tic itching starts again once he stops his medicines. Eczema tic itching leads making his skin reddish and abraded. If any diet can help then please guide?

A. Though food can also trigger eczema symptoms. Thus you must avoid cow`s milk, eggs, shellfish. Avoid dusty areas, pollution. His doctor would have told about the allergens to be avoided just follow them. You can also make him have raw food. It’s said that they help reduce on the return of the symptoms. Use anything as natural as possible, like soaps, clothing and anything which is unnatural. This will help for the eczematic impact to reduce.
