Hi, I am sharing our own story. Our son had eczema since his birth. We had so many terrible nights, him scratching all night and us watching helplessely. We tried everything from steroid to natural home made remedies to ayurveda remedies to homeopathy, But all in vain. But things changed when our washer broke down and we bought the top of the line LG washer that has "Sanitizing wash cycle". After using the new washer our son's eczema got better within days. And this is how we believe it worked.
We were applying a lot of vaseline and aquaphor to his skin regularly as doctors reccomend. Even though we were using organic cotton clothes the vaseline was getting absorbed in the fiber of the cotton and had made a film inside the fabric. That would not only negate the purpose of using cotton but make it worse. It was breeding ground for bacteria. His clothes would feel sticky from inside even though they were looking clean. We tried boiling clothes in order to get rid of the vaseline but made no difference. But the new washer uses the sanitizing cycle and gets rid of it. It takes more than twice the time to run the cycle but the results are amazing.
For us it was nothing short of a miracle. I feel the pain of all the parents and the kids that are going through this terrible experience. But , please check if a simple change like this can make a difference in your case. I hope for the best for everyone.
