Whats the best cure for allergic rhinitis? aside from anti histamines that really makes me drowsy. is there any natural way? something like herbal?

Avoid allergen: If you can find out what you are allergic to (e.g. Animals, dust, grass) you can try to avoid and take local control measures. If not, you might try saline irrigations and then follow by an over the counter trial of local steroids such as flonase. Side effects can include nasal bleeding and dryness. Best to find out the allergies and see if there are specific treatments.

Herbal remedies: Some patients claim herbal remedies are effective for allergic rhinitis. This is an aleternative to conventional medications, though less reliable, and not without potential side effects.
