Stimulating substances of pepper (ginger, pepper, especially pepper) can stimulate the taste receptors of human tongue, and reflexively raise blood pressure (especially diastolic pressure), but have no obvious effect on pulse.

Intravenous injection of capsaicin or capsaicin into anesthetized cats and dogs can cause transient blood pressure drop, slow heartbeat and dyspnea, which is caused by stimulating chemoreceptors or extensors in the lungs and coronary arteries. It can directly excite the isolated guinea pig atrium and contract the blood vessels in the hind limbs of rats.
