Grinding teeth


By Nick Dent

This symptom appears in the early classic books of Chinese medicine Jin Gui Yao Lue (Essentials from the Golden Cabinet) and the Zhu Bing Yuan Hou Lun (Discussion of the Origins of the Symptoms of Disease), and also includes chattering teeth. In these books it was called jie chi,  gnashing teeth, but now it is called nie chi, grinding teeth.
