The tongue is a map of the body. It reflects the general health of the organs and meridians. Your acupuncturist will look at the color, shape, cracks and coating on your tongue.
The tongue reveals the overall condition of the stomach, and how well we are digesting to make blood, body fluids, hormones, and energy; and how well our digestion is distributing these goods throughout the body. The tongue will often confirm the symptoms you have already shared with your practitioner.
