Medically, yohimbine is a pre-synaptic alpha-2-adrenergic blocking agent, also referred to as an alpha 2-adrenergic antagonist. This action increases sympathetic nervous system activity, and can result in increasing the amounts of epinephrine (also known as adrenaline) and norepinephrine in the blood stream. The sympathetic nervous system is involved in controlling the body's response to stress, and also triggers the fight or flight response.

The main effects epinephrine and norepinephrine have on the body include increasing blood pressure and heart rate. Paradoxically, in low dosages yohimbine has been observed to lower blood pressure, which is thought to be from causing dilation of blood vessels, thereby reducing vascular resistance.
