Ayurvedic Tongue Diagnosis: What Your Tongue Says about Your Health

Learn one of the primary diagnostic tools in Ayurveda.

Traditional Ayurvedic Tongue Reading

In Ayurveda, one of the primary investigative tools of practitioners for determining the state of one’s health is tongue diagnosis or evaluation of the tongue.

The tongue is the beginning of the digestive tract, which lumbers on for another 30 feet or so. Since we cannot see much beyond the mouth without some invasive diagnostics, a quick look at the tongue can tell much about the health of your inner digestive lining and its function.

In fact, Ayurveda suggested that the surface of the tongue reflects an entire map of the body, reflecting its overall health.

Tongue Analysis

While looking in the mirror, examine each area on the tongue, looking for differences in:

  • Color
  • Texture
  • Coating
  • Taste buds

According to Ayurveda, the inner lining of the digestive tract is the most important determining factor for overall health. The inner skin, the epithelium, governs delivery of nutrients, removal of digested toxins, and the beginning of lymphatic and immune systems. Examining the tongue can offer useful insight into these functions.

Functions of Healthy Inner Digestive Skin

  1. Hosts trillions of beneficial microbes1
  2. Where 95% of serotonin for mood health is derived2
  3. Where 80% of immune system is found3,4
  4. Protective barrier to ward off environmental toxins5
  5. Delivery of all vitamins, minerals, and nutrients6
  6. Regulates genetic and epigenetic changes to human genome7-9
  7. Beginning of lymphatic circulation18
  8. Main driver of detoxification18
  9. Creates environment for manufacturing of vitamins, hormones, and neurotransmitters

This is, of course, the extremely short list of why inner digestive skin health is so important. The problem with diagnosing inner skin is that we cannot see it—or can we?

Your tongue can give you quick and useful incites about the status of your digestion.

The Perfect Tongue

Before we discuss the “perfect” tongue constitutionally, note that we will all have a tongue that closely reflects our main constitution.

Tongue by Dosha

  • Vata Constitution

The tongue will tend to be thinner, smaller, and a bit rough and dry.

  • Pitta Constitution

The tongue will be a bit redder in color, medium size, and slightly dry.

  • Kapha Constitution

The tongue will be larger, full, possibly light pink, and a bit wet.

Signs of a Healthy Tongue

  • Pink: not pale, scarlet, or red.
  • Pinkish color is consistent across the entire tongue.
  • You would be able to see small cylindrical taste buds on the entire top surface of the tongue.
  • It’s not too wet or too dry. It’s just right—moist!
  • No cracks.
  • Very thin white coating of mucus.
  • No teeth marks or glassiness on sides.

Tongue Diagnosis: Looking For Imbalances

Inside of your stomach and intestines, you have intestinal villi and delicate epithelium, with a thin layer of mucus lining the upper digestion. This coating helps with assimilation of nutrients and breakdown of toxins. Health of digestive skin was classically evaluated by examining one’s tongue. We all grew up with every doctor’s visit starting with a tongue depressor saying ahhh!

When the intestines become inflamed or imbalanced, they produce excess mucus, which bogs down the villi, negatively affecting their ability to detox waste and absorb nutrients. In this case, the tongue would turn red or become overly wet and mucusy.

On the other hand, if the intestines are too dry, as a result of excess stress or dehydration, the villi dry out and lose function, turning the tongue dry, parched, and even pale or cracked. Examine your own tongue and see if you can find one that matches your tongue’s appearance.

Classic Tongue Imbalances

Movie Star Tongue

When the tongue becomes red, smooth, and moist or wet, I call this a “movie star tongue.” While it might be pretty, it is not a functional tongue, and here is why. When there is excess acid in the stomach, the tongue will often reflect that by becoming more red. Due to hypersensitivity of the stomach lining and perhaps the upper part of the small intestine, the taste buds will contract as if trying to hide and protect themselves. The result is a very smooth tongue that looks like it was sanded down and buffed. Such a tongue will often be moist, which is a reflection of the excess mucus produced in the stomach and small intestine to protect the lining.

Irritated Tongue

The irritated tongue reflects intestinal irritation from stress on the tongue. It can be smooth, wet, and pale. The smoothness is because the taste buds are reacting to the stress by contracting or hiding. It is wet because of the reactive mucus production generated as a result of the stress, and its paleness is the result of the stomach’s low production of stomach acid as a way to protect the intestinal wall from further irritation.

Acid Tongue

The “acid tongue” reflects symptoms like occasional heartburn. When stomach acid builds up in the stomach and begins to move upwards, it can upset the lining of the stomach, esophagus, mouth, and tongue. The result is a very red, dry, and often smooth tongue.

Boggy Tongue

A “boggy tongue” reflects a digestive fire that has been turned off. This typically results in a pale, wet, coated, and even swollen tongue depending on what the body type is.

Teeth-Marked Tongue

This tongue generally has scalloping teeth marks along the sides of the tongue. It can also be discolored, where it might be reddish in one area, pale in another, and pink somewhere else. Teeth marks or a scalloped tongue may suggest imbalanced assimilation of nutrients.

Stress Tongue

This tongue, which generally afflicts vata and pitta types, will have many small cracks on the tongue. This is not to be confused with a “geographic tongue,” which normally exhibits many cracks. A “stress tongue” is also typically dry and often unsteady.

Cracked Tongue

Sometimes you will see a deep crack running down the center of the tongue. This may reflect vata strain in the nervous system or spinal stress.

Ama Tongue

Ama, in Ayurveda, is accumulation of improperly digested food that can congest the intestinal tract. An “ama tongue” is when a thick coating builds up on the entire tongue. If accumulation of ama is on the back of the tongue, it is generally a build-up of toxins in the large intestine, small intestine, and colon. A thick coating on the front and back of the tongue suggests ama build-up in the stomach and small intestine.

Pale Tongue

A pale tongue suggests lack of good stomach acid and digestive enzymes needed to properly digest food and deliver minerals, vitamins, and nutrients needed for optimal health. Sometimes this can also be a sign of anemia.

Dry Tongue

For the stomach to produce acid needed to digest hard-to-digest foods, the stomach requires proper hydration. Proper hydration supports a bicarbonate layer of cells that is 80% water and buffers the acids in the stomach. Without adequate hydration, the stomach will not produce acid and the tongue often becomes very dry and slightly pale.

Wet Tongue

A “wet tongue” can be due to excess kapha (mucus) from a severely irritated stomach lining, intestinal wall, undigested proteins like casein or gluten, or from excessive stress.

Swollen Tongue

A “swollen tongue” may suggest a congested lymphatic system backing up into tonsils, adenoids, and tongue. Look for other signs of lymph congestion to confirm this.

Balance Digestion + Change Your Tongue

Each of these tongue imbalances reflects a certain type of digestive imbalance. Please read the articles in my digestive health article and video archives to address your particular issue, or schedule a personalized Ayurvedic consult so we can dig in deeper.

Caring For Your Tongue

Tongue scraping is the simple practice of scraping the tongue before brushing the teeth. Studies have shown that this simple technique:

  • Reduces undesirable bacteria in the mouth that compromise gum, teeth, and oral health.10
  • Reduces volatile sulfur compounds (VSC) that are byproducts of mouth bacteria linked to bad breath.11
  • Increases function of taste buds to better taste and digest food.12
  • Changes environment of mouth to reduce putrefaction and decrease bacterial load.13

Toxins, or ama (as we discussed earlier), collect on the back of the tongue and can cause obstructions in respiration and foul smell.14

Copper may be the best metal for tongue scraping because the mouth is loaded with both good and not-so-good bacteria. Copper not only seems to be toxic to the bad bacteria, it also provides important enzymes that are needed for the healthy microbes of the mouth to survive.15,16

In one study, the antiseptic benefits of copper were so great that, when copper was put in hospital rooms as furnishings, the surface bacteria count on all the surfaces in the hospital room was significantly reduced.17 Some hospitals are now incorporating copper furnishings as part of their anti-bacterial strategies.

How To Scrape Your Tongue

In the morning, right after you wake up, scrape your tongue. Make it the first thing you do. Even if you wake up in the middle of the night, scraping the tongue followed by a glass of water can reduce accumulating digestive ama (toxins).

With a relaxed tongue, using your U-shaped tongue scraper, gently reach to the back of the tongue and scrape from back to front. Repeat this 5-10 times, reaching as far back as comfortable, rinsing the scraper after each pass. A slight gag can help bring up some mucus and ama from the back of the throat.

Follow tongue scraping with brushing (with non-fluoride toothpaste), flossing, and a large glass of water.

To complete an Ayurvedic oral hygiene routine, this can be followed by oil pulling. Of course, this would require another round of tooth brushing.

Get into the habit of scraping your tongue prior to each brushing.
