Abstract in brief

The study found that nasal inhalation of black pepper oil (BPO) for one minute improved swallowing reflexes, increased serum substance P, and enhanced regional cerebral blood flow, particularly in the insular cortex and orbitofrontal cortex, in older poststroke residents.
The intervention resulted in a shorter latency of swallowing reflex, more swallowing movements, and better brain activity in specific regions associated with swallowing, suggesting potential benefits for managing dysphagia in elderly patients after stroke.
Overall, inhaling black pepper oil may help improve swallowing function in older people with dysphagia, regardless of their mental or physical condition, potentially reducing the risk of pneumonia.
