Eczema is itchy because there are toxins that are being expelled through the skin and your body wants those toxins OUT!
As we have defined, your body chose the skin to expel those toxins, the dirt, the poisons through your skin. The best we can do when this happens is to allow, to help this expulsion of toxins. You can do this be scratching, by dunking in hot water, by getting a clean absorbent cloth and absorbing the eczematic fluid.
This is not the time to STOP the fluid from coming out. You will get temporary results and the eczema will rage on again. You have to stop eczema from the SOURCE.
