What It Is?

Histamine is released by immune cells (mast cells and basophils) when the body encounters allergens or other triggers. It can cause clinical signs like itching, swelling, runny nose, watery eyes, or even more severe reactions. Antihistamine is bound to histamine receptors in the body, preventing histamine from attaching and triggering these clinical signs.

Why It's Important?

Antihistamines are often used to manage allergies, itching, or mild allergic reactions and, in some cases, to prevent motion sickness or nausea. However, whole foods containing quercetin can provide the same relief from allergies.
