Yellow Tongue Coating

How Chinese medicine reads a yellow tongue coating into the 5 patterns behind it, and the points for each. Distinct from this site's own Coated Tongue page. Acupuncture only — no herbs.

A tongue sign is one piece of a larger picture and should be read alongside the rest of the presentation by a qualified practitioner.
