I am mildly allergic to pollen. Worst attach of hay fever I ever had was from a product that was new in town and only sold in Chinese grocery stores, it was called Chinese chalk because it resembled sticks of blackboard chalk and was made of pure pollen and very effective against cockroaches. I got some and applied it in all the areas of my place.. HAY FEVER! I had an idea it was from the chalk so I phoned Poison Control, that's how I found out what the stuff was made on. The stuff was around for a couple of years then went off the market and no longer available.
From the web: allergic rhinitis is triggered by the pollons of specific seasonal plants and is commonly known as hay fever because it is most prevalent during the hayng season.
