How we rate
Each score is evidence grade + practical adjustment. The grade reflects how well studies show that kind of product relieves allergy symptoms, and every grade cites its sources on the review page. The adjustment (-0.7 to +0.3) accounts for side effects, convenience, and value, and is kept small so it can never outweigh the evidence. Commissions play no part in the score. We may earn a commission on purchases; see our disclosure and methodology.
- Grade AStrong evidence4.5 base
Strong evidence: First-line. Consistent randomized trials or meta-analyses show symptom relief.
- Grade BModerate evidence3.8 base
Moderate evidence: Benefit shown, but in fewer or smaller trials.
- Grade CLimited evidence3.0 base
Limited evidence: Plausible and low-risk, but trials are small, low quality, or show cleaner air without a consistent symptom benefit.
Not recommended for routine use: Works, but the harms outweigh it next to better options.
