Substance P plays a crucial role in relaying sensory information from the pharyngeal region to the brain and spinal cord during the normal swallowing process, thereby influencing the timing of the swallowing reflex. Research indicates that daily consumption of 4.5 micrograms of capsaicin significantly enhances the release of Substance P within the pharyngeal nerves, thereby improving swallowing efficiency.
