I heard on the radio the blood stem cells are being used with bone marrow somehow to eliminate allergies and that the treatment will be available in 4-5years. It's a shame that INNV couldn't or hasn't gotten fluticare ANDA approval yet. With the stem cell treatment, clarispray, flonase, nazacort and all the generics, it's a worry for sure. I think INNV has missed the boat on so many things and that the height of INNV might have actually, only been the past, with the fluticare hype.
