The tongue has acupuncture points connecting to the entire body. This diagram of the tongue shows the latest organ representations from the work of Dr. Y. Omura. You might look at your tongue. If you find irregularities or changes in color over the areas noted on the diagram you might consider seeing your health provider. Tongue diagnosis is as ancient as acupuncture and when abnormalities present, the acupuncturist taps the appropriate meridians that are related to the organs.
