AI Tongue Diagnosis Tool

In Traditional Chinese Medicine, the tongue is a window to your internal health. Its color, coating, shape, and moisture reveal patterns of balance and imbalance in your organ systems.

This tool offers two ways to analyze your tongue: AI Photo Analysis using your camera or an uploaded photo, and Guided Self-Assessment where you answer questions about your tongue's appearance. Both methods identify your likely TCM constitution and provide personalized wellness recommendations.

How to Take a Good Tongue Photo

Follow these tips to get the most accurate tongue diagnosis results, whether using AI photo analysis or showing your tongue to a TCM practitioner.

1
Best Time: Morning
Examine your tongue in the morning before eating, drinking, or brushing. Food and beverages can temporarily alter tongue color and coating.
2
Use Natural Daylight
Natural daylight provides the most accurate color. Avoid yellow incandescent or colored LED lights, which distort tongue color.
3
Stick Out Naturally
Extend your tongue comfortably without straining. Do not force it out too far or curl the tip, as this changes the color.
4
Quick — 3 to 5 Seconds
Tongue color changes quickly with pressure. Capture or observe within 3-5 seconds of extending. Prolonged extension causes reddening.
5
Do Not Scrape or Brush
Never brush, scrape, or clean your tongue before a diagnostic photo. The coating carries essential diagnostic information in TCM.
6
Avoid Colored Foods
Avoid coffee, tea, candy, colored drinks, and strongly colored foods for at least 2 hours before, as they stain the tongue temporarily.
7
Good Camera Angle
Photograph straight-on, filling the frame with the tongue. Include the full tongue body from root to tip. Keep the camera steady.
8
Relax Your Face
Keep your face relaxed. Tension changes tongue shape and color. Open your mouth comfortably and let the tongue rest naturally.

Frequently Asked Questions

How accurate is AI tongue diagnosis compared to a TCM practitioner?
AI tongue analysis can identify general color, coating, and shape patterns, but it cannot replace the expertise of a licensed TCM practitioner. A practitioner combines tongue diagnosis with pulse reading, symptom history, and physical examination to form a complete diagnosis. This tool is designed for educational purposes and to help you understand basic TCM tongue patterns, not to provide a medical diagnosis.
What time of day is best to examine your tongue in TCM?
The best time to examine your tongue is in the morning, before eating, drinking, or brushing your teeth. Food, beverages (especially coffee, tea, or colored drinks), and brushing can all temporarily change the appearance of your tongue coating and color. Natural daylight provides the most accurate color representation.
Can the color of my tongue change throughout the day?
Yes, your tongue appearance can shift throughout the day. Eating, drinking, stress, fatigue, and even emotional states can cause temporary changes in tongue color and coating. This is why TCM practitioners recommend examining the tongue in the morning under consistent conditions. Persistent changes that remain over weeks are more clinically significant than daily fluctuations.
Should I brush or scrape my tongue coating before taking a photo?
No, do not brush, scrape, or clean your tongue before taking a diagnostic photo. The coating on your tongue carries important diagnostic information in TCM. Brushing or scraping removes the coating that a practitioner needs to evaluate. Simply stick out your tongue naturally for the photo without any preparation beyond normal face washing.
