Nutrients connected to Hay Fever
A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.
- Pine pollenDocumented risk
Pine pollen is an allergen for some pollen-allergic people; the cited study did not test supplements.
- Chrysanthemum TeaDocumented risk
Some people with weed-pollen allergy (ragweed, mugwort) react to herbs from related daisy-family plants. Chrysanthemum tea itself was not tested.
- Polyphenols: quercetin and resveratrolPreliminary or mixed
One small placebo-controlled trial of an absorbable quercetin product lowered some hay fever symptom scores; a 2025 review said larger trials are needed. Not a treatment.
- CinnamonPreliminary or mixed
Preliminary research on a Ceylon cinnamon extract nasal spray; more reliable evidence needed.
- ButterburPreliminary or mixed
Studies of an oral leaf extract suggest it may help hay fever symptoms; evidence is limited.
- Almond mushroom (Agaricus subrufescens)Preliminary or mixed
In a 60-person trial in birch-pollen-allergic blood donors, symptom and medication reports were lower with the extract; needs confirmation.
- CinnamonPreliminary or mixed
Preliminary research on a Ceylon extract nasal spray; more reliable evidence needed.
- Tiger milk mushroomPreliminary or mixed
One randomised trial of 108 people reported lower nasal symptom scores over 30 days with a cultivated sclerotium preparation (25 and 31 people analysed); allergy blood markers did not change. Needs independent repeat.
- Globe ArtichokesDocumented risk
Case reports link Compositae pollen allergy with reactions to eating artichoke; evidence is limited.
