Histamine is a extensively known mediator to induce bronchoconstriction and vasodilation in an allergic response. However, no vital involvement of beta-hexosaminidase is reported on allergic responses . The reactions can be as mild as a rash and as extreme as an anaphylactic shock that can lead to death. Subsequent exposure of allergens will trigger mast cell degranulation, releasing mediators that exhibit allergic signs.
Allergist/immunologists listed as ABAI-certified have efficiently passed the certifying examination of the ABAI following their fellowship.

In the early part of allergic response, quercetin was discovered to be stronger than ketotifen fumarate in inhibiting histamine launch. Flavonoids have been reported to have anti-allergic properties by inhibiting histamine and IL-4 launch .
