There is a homeopathic remedy that I have used with great results. It is Ambrosia--- It's not a common remedy and you may not be able to buy it at a health food store. You may have to order it from a Homeopathic Pharmacy but it is well worth the trouble because your problem is very miserable --to say the least.

The remedy is derived from "rag weed" and I have only used the 30X potency but it works well.

God Bless---Harry
