Surprising Benefits of the Humble Eggplant

7. Lower Blood Pressure

Acetylcholine, a well-known neurotransmitter, occurs naturally in eggplants. The neurotransmitter prompts parasympathetic nervous activity that suppresses reactions in the sympathetic nervous system. This suppressive effect may help lower blood pressure. Activity in the sympathetic nervous system is also associated with stress and psychological state. Distressing emotions can raise blood pressure, so acetylcholine's calming effect on psychological responses may also reduce blood pressure.
