Walking into the kitchen, have you ever noticed the appearance of those shriveled pieces of old ginger on the stove? The skin of old ginger is wrinkled, yet when cut open, it reveals a yellow, substantial interior; a single bite sends a sharp spiciness straight to the throat. Traditional Chinese medicine often says "ginger can warm the middle and dispel cold," but did you know? The form of this old ginger bears a certain resemblance to the tongue condition we are discussing today — a tongue with teeth marks, swollen and plump, with impressions on both sides, as if gently bitten by teeth. What exactly is going on here? Is the body quietly telling us something? Let us slowly unveil this mysterious veil from the warmth and smoke of the kitchen.
What Signal Does the "Swollen Tongue" on the Tongue Actually Hide?
In clinical practice of traditional Chinese medicine, a tongue with teeth marks, swollen and plump, with impressions on both sides, is known as a "teeth-marked tongue" or "enlarged tongue." It is like a mirror, reflecting the imbalances within the body. Many people notice when looking in the mirror that the edges of their tongue appear as if soaked in water — puffy and bulging, with clear tooth impressions on both sides. This is no joking matter of "the tongue being too fat"; rather, it is an important clue in TCM pattern differentiation. Traditional Chinese medicine holds that the tongue is the sprout of the heart and the external manifestation of the spleen. Changes in the shape of the tongue body are often closely related to fluid metabolism and the movement of qi and blood within the body.
Spleen Deficiency with Dampness Excess Pattern — Dampness Traps the Tongue and Traps You Too
If your tongue is as swollen and large as a water-soaked sponge, with teeth marks as deep as if carved into it, and you simultaneously feel heaviness in the body, lack the energy to move, experience easy abdominal bloating after meals, and have sticky, unformed stools, this is most likely the work of "spleen deficiency with dampness excess." TCM theory points out that the spleen governs the transformation and transportation of water and dampness, functioning like a range hood in the kitchen, responsible for expelling dampness from the body. Once the spleen's function weakens, water and dampness will linger in the body, and the tongue will naturally swell up like a steamed bun soaked in water. In meridian theory, the He-Sea point of the Spleen Meridian, Yinlingquan (SP9), is located on the medial aspect of the lower leg, in the depression below the lower border of the medial condyle of the tibia and the medial border of the tibia. It is a point often mentioned in TCM when discussing the transformation and transportation of water and dampness. The Lingshu · Benshu refers to it as "in the depression below the medial auxiliary bone of the knee," and the ancients believed that the qi and blood of the Spleen Meridian gather deeply here like a spring, closely related to the distribution and movement of fluids in the body. Clinically, this type of constitution is relatively common in environments of prolonged sitting and irregular eating habits.
For maintenance, one may start with ingredients from the kitchen. Ingredients such as Chinese yam, poria, and coix seed are somewhat helpful for spleen deficiency with dampness excess. You can boil them in water to drink, or make them into porridge. But remember, this is only one method of daily maintenance. If you truly wish to adjust your constitution, it is still necessary for a licensed TCM practitioner to differentiate and treat according to individual conditions. After all, everyone's degree of "spleen deficiency" differs, and the severity of dampness varies; blindly following trends may actually prove counterproductive.
Yang Deficiency with Water Diffusion Pattern — The "Little Furnace" in the Body Is Not Strong Enough
Some people's teeth-marked tongue is not only swollen and large but also appears pale and moist, like vegetable leaves that have been touched by frost. This tongue presentation is often accompanied by manifestations such as aversion to cold, cold hands and feet, soreness and weakness of the lower back and knees, and frequent nocturia. What is going on here? The Huangdi Neijing states: "Yang qi is like the sky and the sun; when it loses its place, life is cut short and does not manifest." The "yang qi" here is like a little furnace in the body, responsible for warming and propelling the movement of fluids. When yang qi is insufficient, fluids are like river water in winter — flowing slowly, even freezing into ice. In such an environment, the tongue will naturally become swollen, large, and slippery with moisture. In the Ren Meridian, at a point 3 cun below the umbilicus, there is an acupoint named Guanyuan (CV4), also known as Dantian and Xiaji, which is the Front-Mu point of the Small Intestine. The Suwen · Ju Tong Lun records that "the Chong Vessel originates from Guanyuan," and the ancients regarded this area as an important site for the storage of original qi in the human body. Its name implies "the pass of original qi," closely related to the warming function of yang qi.
For the condition of yang deficiency with water diffusion, warming ingredients from the kitchen such as fresh ginger, cinnamon, and Sichuan pepper may offer some help. For example, steeping a few slices of fresh ginger in water to drink can help warm the middle burner. However, note that if there are simultaneously manifestations of "heat rising," such as dry mouth and throat and sore, swollen throat, it may belong to a complex state of "upper heat and lower cold," and simple warming supplementation is not appropriate. Clinically, if some individuals simultaneously present with a dull, dark complexion and tortuous sublingual veins, there may also be concomitant blood stasis, and the direction of regulation should be comprehensively judged by a licensed TCM practitioner.
Liver Depression Attacking the Spleen Pattern — Emotions Can Also Make the Tongue "Swell"
Have you ever noticed that when you are in a bad mood, not only can you not eat, but even your tongue seems tied in knots? A tongue with teeth marks, swollen and plump, with impressions on both sides, sometimes accompanied by distending pain in both hypochondria, frequent belching, and low mood or irritability. Behind this, it may be "liver depression attacking the spleen" at work. TCM theory holds that the liver governs free coursing and regulates the movement of qi; the spleen governs transformation and transportation, and the two influence each other. When there is prolonged high pressure and excessive worry, liver qi becomes depressed, like a blocked water pipe, which in turn affects the spleen's transformation and transportation function, leading to internal retention of water and dampness. For liver qi depression, there is an acupoint often mentioned in meridian theory — Taichong (LR3), also known as Dachong, located in the depression posterior to the gap between the first and second metatarsal bones on the dorsum of the foot. It belongs to the Foot Jueyin Liver Meridian and is the Yuan-Source point of the Liver Meridian. The Lingshu · Jiu Zhen Shi Er Yuan states: "When the five zang organs have diseases, one should select from the twelve Yuan-Source points." The ancients believed that the qi and blood of the Liver Meridian converge here, and changes in its pulsation can reflect the state of liver qi free coursing.
This type of teeth-marked tongue often appears slightly dark red, or with stasis spots. For maintenance, one may try ingredients from the kitchen such as aged tangerine peel, rose buds, and mint. Aged tangerine peel can regulate qi and strengthen the spleen, rose buds can soothe the liver and relieve depression, and mint can clear the head and eyes. However, these ingredients can only serve as auxiliary daily tea beverages; the true focus of regulation lies in relieving emotions and adjusting one's daily routine. Clinically, the liver depression attacking the spleen type is relatively common in people who stay up late for extended periods and work in high-pressure environments, often accompanied by manifestations such as insomnia and frequent dreaming. If you wish to improve fundamentally, it is recommended to consult a formal medical institution and have a licensed TCM practitioner formulate a personalized plan.
