What colour is your tongue?
Came across this interesting article today! 🤪
TD;DR:
Traditional Chinese Medicine has long used tongue colour and texture to assess health. Now researchers are merging this ancient practice with AI. A 2024 study using standardized lighting and machine learning analyzed over 5,000 tongue images, achieving 96.6% accuracy in predicting conditions like diabetes, anemia, asthma, and even COVID severity.
The challenge has always been subjectivity and lighting variation, but new systems use controlled LED kiosks to capture consistent images. Researchers found correlations such as:
- White tongue: possible iron deficiency
- Bluish-yellow coating: diabetes
- Purple/fatty layer: certain cancers
- Deeper red hues: more severe COVID
While promising, experts warn that tongue color alone isn’t enough for diagnosis, AI tongue analysis should complement, not replace, other medical tools.
I wonder what it would tell me after I have had a curry? 😅
