The Claim
People often believe that quercetin can fully replace conventional antihistamines due to its natural ability to inhibit histamine release.
Origin
This idea is popularized by health websites and alternative medicine practitioners who advocate for natural allergy treatments.
What Science Says
While quercetin does show some antihistamine effects in laboratory studies, clinical trials demonstrate that it is not as effective as conventional antihistamines in managing allergy symptoms. It may serve as an adjunct rather than a replacement.
Verdict
Mostly False
