Like all allergy , it is an example of misplaced immunity, since pollen cannot harm us. In my opinion, conventional treatments for hay fever are not very good. Having had an intense ragweed allergy for most of my early life, I have tried them all. Desensitization shots are expensive, painful, and not without risk. Moreover, the percentage of patients who experience satisfactory relief of symptoms after years of shots is disappointingly low.
Antihistamines are the mainstays of hay fever treatment.
They will often reduce itching in the eyes, ears, and throat, dry up a runny nose, and reduce sneezing attacks, but their actions on the brain also make you drowsy and depressed. I consider antihistamines toxic drugs with adverse effects on consciousness, and I would go to great lengths to avoid them. In the past few years new antihistamines have appeared that are not absorbed into the brain. These products do not cause drowsiness and depression, but they do not work for everyone, and they are expensive. An objection to all antihistamines, whether they enter the brain or not, is the suppressive nature of their action.
