Really interesting insight. I didn't even think about the honey's effect over the long-term scale such as a year plus as you've pointed out. Perhaps it is that most people would seek immediate relief and the honey just isn't great at treating symptoms, but could be a great solution for actually getting rid of allergies altogether instead of relying on allergy shots.
Definitely need to ponder on this some more and do further research 🤔.
Thank you for bringing this to light @kzeta!
