**Data source**
TCM data is compiled into the app (no external file). Each iris zone × eye-side combination maps to a specific TCM organ system entry. The TCM map is eye-side-specific: for example, the middle-temporal zone is the **right lung** in OD and the **left heart / pericardium** in OS — which is the same distinction already present in the iridology iris zone map.
**Five Elements framework**
Each TCM organ belongs to one of the Five Elements (Wu Xing):
| Element | Color | Season | Climate | Taste | Emotion | Sense organ |
|———|——-|——–|———|——-|———|————-|
| **Wood** | Green | Spring | Wind | Sour | Anger / Frustration | Eyes |
| **Fire** | Red | Summer | Heat | Bitter | Joy / Anxiety | Tongue |
| **Earth** | Yellow | Late Summer | Dampness | Sweet | Worry / Overthinking | Mouth |
| **Metal** | White/Grey | Autumn | Dryness | Pungent | Grief / Sadness | Nose |
| **Water** | Blue/Black | Winter | Cold | Salty | Fear / Will-power | Ears |
The element colour is used as the card accent throughout the panel.

| **Meridian functions** | Key physiological roles in TCM theory |

| **Acupoints** | Top acupressure/acupuncture points with brief descriptions |

– Primary acupoints (WHO standard point codes, e.g. LV3, HT7)
