What does epinephrine do in the body? It increases our appetites. The adrenal medulla is the principal site of the conversion of the amino acid tyrosine into the catecholamines; epinephrine, norepinephrine, and dopamine. It gives us self-confidence, a feeling of safety and security. These compounds act as both neurotransmitters, delivering signals between nerve cells, and hormones . According some advice it should be enough to increase Dopamine to solve excess Serotonin. The neurotransmitters dopamine, norepinephrine (noradrenaline) and epinephrine (adrenalin) resemble each other closely. Dopamine directly affects blood pressure and is also considered as a vasopressor. Physiologic principles of catecholamines have numerous applications within pharmacology.
