This might be of some interest to all you fellow sufferers.
Recently I went to a Holistic Clinic and was advised to use Luffa Complex for hayfever and Plantago for the sinuses and I have to say they're working a treat.( I'm using the tincture form) No side effects and no contra indications. They're both made by Vogel( formerly Bioforce) But you can buy them in any health shop. they do cost around £7.99 each, but worth it. Check out:

Also, I've been having a couple of cups of Nettle tea everyday which is a natural antihistimine. Its very nice by the way, light and refreshing!!!!
And using Sterimar, which is just a sea water spray you buy from Boots or any other chemist.
Try them, there's nothing to lose and you can continue with your regular tablets/sprays if you want to.
All I can tell you is that i've only been doing this regime for a week and a half and the difference is amazing. Hope it works for you too!
