I started taking Iodine and using black seed oil (internal and external)
It works wonders for the dyshidrotic eczema fluid filled blisters as well, they disappear within a couple of days and then the skin starts to heal.
My symptoms have significantly diminished from these two treatments, though it is still 5% (maybe) evident. I'm hoping with continuous use it will deplete away.
My eczema mainly comes on in summer. I am thinking it is a yeast problem (like others have said). It would kind of make sense as it would slow down the yeast in colder months and when summer comes it does the opposite.
