its not natural...but a friend of mine swares by it...

its an intra muscular injection, you have to have a drs perscription for it. but you just need one at the start of the season, and never experience hayfever at all. her son experiences it so bad, he has spent many days lying on the couch with cold washers on his face cause he couldnt open his eyes. since she started giving him the needles (he actually needs 2 cause he is so big) he hasnt gotten so much as a runny nose.

its called:
Depo-Medrol, 40mg/1ml amp for IMI injection.

you do need a script, so might be worth asking your dr about it, see if its worth it or not...im not sure on what it is actually or sideeffects etc..so talk to your dr, all i know is she thinks it is holy water how much it has helped her kids.
