Which Meridian starts at the lower extremity and spreads over the tongue's lower surface?

The Spleen Meridian begins at the lower extremity and travels up through the inner aspect of the leg, eventually connecting to the tongue's lower surface. This meridian is associated with digestion, nutrient absorption, and the management of bodily fluids. Its pathway reflects these functions, as it spans areas where these processes are vital, starting from the foot and moving up to the tongue.

In Traditional Chinese Medicine, the Spleen is crucial for transforming food into Qi (vital energy) and blood, so the connection to the tongue, where the taste is perceived and possibly related to digestive health, is significant. The tongue's condition can reflect the state of the Spleen, making this pathway particularly relevant in clinical practice for diagnosing and treating Spleen-related issues.

For example, the Liver Meridian affects the body's emotional and detoxification processes, while the Kidney Meridian is associated with reproduction and growth. The Gallbladder Meridian plays a role in the digestion of fats and the processing of bile.
