White, Yellow, or No Coating? What Tongue Coating Reveals About Your Body in TCM

In Traditional Chinese Medicine (TCM), your tongue acts like a health report card. Its color, shape, and coating can reveal imbalances before symptoms become obvious. While the tongue body reflects your organ health and energy balance, the tongue coating tells a different story—it shows what’s happening on the surface and inside your digestive system.

If you’ve ever wondered about the tongue coating meaning in TCM tongue diagnosis, here’s what a white, yellow, or no coating might be telling you.
