There are a number of herbs that some people find effective. Stinging nettle is one. Chamomile is another, but shouldn't be used by people allergic to ragweed. There are herbs used to tackle the symptoms of allergies, such as the cough, congestion, sore throat, etc. that you can grow yourself. I am growing stinging nettle, chamomile and other herbs as I don't have bees and I want to be as self sufficient as possible. I go through a lot of honey, as some grasses pollinate in the spring and othes later nearer fall. I have a good number of herb books, and check at least three from different herbalists for each herb I use or ailment I'm looking up. I've found a few books in yard and library sales, but even the more expensive new books will pay for themselves quickly. I've barely started to learn. It will continue to be a lifetime committment, but with the way things are going, I think it is an important skill to learn. There are several people on this forum who would be of more help, as they are herbalists and have studied and used herbs for many years. I hope they chime in with their advice.
