"Chronic cough chronic cough,

 can be socially isolating and disabling, and people come from all over Europe to my cough clinic because the cough is ruining their lives. Yet treatment options are limited, with remedies little better than honey and lemon," Morice added.

Morice and his colleagues have identified a group of protein molecules called receptors that sit on the surface of nerve cells and allow signals to be passed inside nerve cells.

They have shown the "very cold" receptor (TRPA TRPA Tahoe Regional Planning Agency 1) on nerve cells is stimulated by a cinnamon extract in normal volunteers, leading them to cough.

The researchers have also successfully cloned the TRPA1 receptor to allow them to investigate the nerve endings.

The researchers have just begun a large-scale patient study that will try to identify existing blocking agents, although the ultimate goal of research is to restore the cough reflex cough reflex
