Sign · 舌红少苔
Tongue with little or no coat
A tongue that looks peeled or glossy, with almost no coating.
This page is a reference entry, not an assessment. It says which patterns the sign belongs to in the table this site is built on, at what weight, and where else on the site it appears. Having a sign is not having a pattern — most people have several of these at once, and the self-check is where they are weighed against each other.
What weight it carries
Every sign in the table is filed against one or more patterns at one of three weights. The weight is about diagnostic usefulness, not severity: a defining sign is one the pattern cannot be argued without, which is a different thing from a sign that is dangerous.
| Pattern | 中文 | Weight |
|---|---|---|
| Kidney yin deficiency | 肾阴虚证 | Defining |
| Liver yin deficiency | 肝阴虚证 | Common |
| Damp-heat | 湿热证 | Supporting |
Defining for one pattern
Without it the pattern is hard to justify. These carry ×3 in the self-check.
Common for one pattern
Usually present, and its absence counts against the pattern. ×2.
Where it appears on the site
No condition page currently lists this sign by name. It is still scored in the self-check, where it is reached through the follow-up questions rather than through a dedicated page.
