None of them.......I tried all most all of the rememides available and none help me.....if your determined to give it a go then there is a really good health food shop and pharamacy on the Lisburn Road in belfast just past the Fire station opposite the park...sorry can't remember the name.
people "do" hayfever in different ways and homoeopathy is patient specific so a general hayfever remedy picked up in a shop may not work on you. there are different potencies to consider.

I personally swear by homoeopathy, cleared my baby sons eczema completely.
