Dear Pasotto,
I have the same problem with neutrophiles. The myeloma treatments I undergo sometimes cause a neutrophiles drop. Now I use so-called "Elevterokok", an alcohol solution of Sieberian ginseng (if correct, not sure). Anyway, after everyday consuming this solution (a spoon) is my neutrophiles count better (approx. 1,6). I know this solution is not some kind of magic but I am not the only one using it, at least in Slovenia, where I come from. Perhaps you should try, it is not expensive (approx. 20 eur per month).
