Apart from inspecting tongue body, the tongue surface should be scraped and the fur should be examined to identify the rooted or rootless fur and the presence of stained fur. Scrape the floating fur softly with tongue deflector and further inspect the tongue body carefully If the tongue fur is not scraped away or keep snasty, pathogenic factors in the interior are indicated. If the tongue fur is easy to scrape off and bright, clean and smooth tongue body is revealed, deficiency syndromes are indicated. In addition, we should observe the movement of the tongue and ask patients about their taste. See Diagnosis and Syndrome Differentiation.
