FWIW, Colloidal silver will eliminate the itching, as well as get rid of the excema from my experience.
I had a patch on my elbow for years that itched so bad I would scratch and pick at it until it bled. My dad had the same thing, so it might have been passed down. Any way I healed it with CS.
Just keep it moist with the CS.
I have also used it for cold sores, bug bites, infections. It works.
