Sign · 口舌生疮
Recurring mouth ulcers
Sores inside the mouth that come back, often when run down or short of sleep.
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 |
|---|---|---|
| Damp-heat | 湿热证 | Common |
| Kidney yin deficiency | 肾阴虚证 | Supporting |
| Spleen yang deficiency | 脾阳虚证 | Supporting |
