I too am interested in this.
I used to take a 10mg ceterizine (antihistamine) pill for this, but a few weeks ago when the season started for me i popped a few for about a week and started to look like the Michelin mascot.
I would not really like to take a tablespoon of honey since i want to keep things keto but if it really helps i am willing to try.
I heard it should be unprocessed and "local" honey so you are mostly exposed to the same pollen as you inhale at home. I don't know how local it should exactly be as there seems to be nobody selling within a couple of km. On the other hand i have allergies no matter where i go.
