Epinephrine, also known as adrenaline, is a vital hormone, neurotransmitter, and emergency medication used primarily to treat life-threatening allergic reactions (anaphylaxis). Naturally produced by the adrenal glands, it triggers the body’s "fight-or-flight" response during acute stress by narrow-tuning blood vessels, relaxing airway muscles, and increasing heart rate.
