When we open ancient Chinese medicine classics, physicians through the ages never overlooked the small area of the lips during inspection. The ancients said, "Nine out of ten people have blood stasis." Though an exaggeration, it points to how common sluggish qi and blood circulation is among modern people. On streets, in subway cars, you may have noticed that many people's lips are not a healthy rosy color, but veiled with a layer of bluish-purple or dull darkness, varying in intensity. Is this inadvertent color simply natural, or is it a whisper from the qi and blood within? Today, it deserves our serious attention.
I. Bluish-Purple Lips: Insufficient Yang Qi and Stagnation of Cold Pathogens
If the lips show an obvious bluish-purple tint, or even darken toward black, traditional Chinese medicine largely attributes this to "cold" and "stasis." Clinically, this condition is more common in people who spend long periods in cold environments or who are constitutionally yang-deficient and sensitive to cold.
From the perspective of etiology and location, the root lies in the spleen and kidney. The spleen opens into the mouth, and its luster manifests on the lips, while the kidney is the root of yang qi for the entire body. When the warming function of kidney yang weakens, the spleen earth loses its warmth and nourishment, and cold pathogens easily arise internally in the middle burner. The nature of the disease is root deficiency with branch excess: yang deficiency as the root, and cold congealing with blood stasis as the branch. In terms of disease progression, if left unaddressed, the cold congealing deepens, qi and blood movement becomes increasingly sluggish, and the bluish-purple color may spread from the lips to the cheeks and even to the extremities. Accompanying symptoms include aversion to cold, cold limbs, preference for warmth and pressure on the abdomen, loose stools, and listlessness. The tongue is often pale and swollen with tooth marks on the edges, with a white and slippery coating; the pulse is deep and slow, or deep, thready, and weak. The key mechanism is "failure of warming and transportation; blood congeals when it encounters cold"—like a river freezing in winter, water naturally flows slowly.
Huangdi Neijing · Suwen · Chapter 62: Treatise on Regulating the Channels states: "Blood and qi love warmth and fear cold. When cold, they become astringent and cannot flow; when warm, they dissipate and move." This reveals the essence—blood and qi naturally prefer warmth and fear cold. When subjected to cold, circulation becomes sluggish; when warmed, it returns to normal. This is the most apt annotation for cold-congealing causing blood stasis.
For care, the diet should favor warmth over coldness. In daily life, appropriately increase warm-natured foods such as fresh ginger, longan, beef, and mutton. Note that moderation is needed; please consult a licensed TCM practitioner for specifics. For rest, sleep early to nourish yang qi and avoid staying up late, which depletes kidney essence. For emotions, maintain a calm mind; excessive fear or melancholy can quietly consume yang qi. For exercise and guidance, choose gentle and sustained activities such as Baduanjin or walking, allowing the body to warm slightly and qi and blood to flow naturally. If the lips are clearly bluish-purple and you cannot judge the condition yourself, be sure to visit a regular medical institution and let a licensed TCM practitioner conduct a comprehensive differentiation based on tongue and pulse.
II. Dark Red Lips: Qi Mechanism Stagnation and Blocked Blood Circulation
There is another type of purplish-dark discoloration—not bluish-purple, but a dull dark red like overnight pork liver, gloomy and lacking luster. This is a common signature complexion in people under high stress, prone to excessive thinking, and often harboring suppressed anger.
The cause of this condition lies in "qi." The liver governs free coursing and regulates the qi mechanism of the entire body. When emotions are frustrated, or when one is under long-term tension and suppression, liver qi tends to bind. Qi is the commander of blood: when qi moves, blood moves; when qi stagnates, blood stasis occurs. The disease location is mainly in the liver and heart channels, because the liver channel encircles the inner lips, and the heart governs blood vessels with its luster manifested on the face. The nature of the disease is excess or mixed deficiency-excess, with qi stagnation and blood stasis at the core. In terms of disease progression, if qi depression persists over time, it may transform into fire, and the dark red lip color may be accompanied by bitter taste, dry throat, and irritability. Such people often feel distension and fullness in the chest and hypochondrium, sigh frequently (only feeling relief after sighing), and women may experience irregular menstruation or breast distension before menstruation. The tongue may appear dark purple or have ecchymotic spots, with engorged and tortuous sublingual veins; the pulse is wiry or choppy.
As the saying goes, "All diseases arise from qi." Once the qi mechanism halts, blood flow becomes like a traffic jam—unable to advance or retreat. Dark red lips are the external display board of internal traffic congestion. Unlike cold-congealing blood stasis, this is not a lack of warmth, but a lack of the "driving force" of qi.
The key to care is "coursing" rather than "tonifying." In the diet, appropriately use qi-moving ingredients such as tangerine peel, rose flowers, and hawthorn, steeped in water as tea. But moderation is required; do not overdo it. For rest, be especially sure to ensure deep nighttime sleep, giving liver blood time to replenish. Emotional regulation is of utmost importance—learn to express emotions rather than suppress or erupt. For exercise, recommend stretching guidance exercises or dance that allow stagnant qi to dissolve with sweat. Remember, if the dark red lip color persists or is accompanied by chest tightness or pain, this cannot be resolved by home care alone. You must see a licensed TCM practitioner for a face-to-face consultation to carefully discern the relative severity of qi stagnation versus blood stasis.
III. Pale Purple or Purplish-Black Lips: Spleen Deficiency with Damp Retention and Insufficient Source for Qi and Blood Generation
The third lip color is pale purple or pale dark, lacking blood color, and the lips may even appear dry and lusterless. This is another scenario, rooted in the spleen and stomach.
The spleen and stomach are the acquired foundation and the source of qi and blood generation. Irregular diet, overexertion, or chronic illness with loss of nourishment can all damage the spleen and stomach. Once spleen qi is deficient, transportation and transformation fail. Not only is qi and blood production insufficient, but damp turbidity is also generated. Dampness is heavy, turbid, and sticky, which in turn obstructs the movement of qi and blood, resulting in a state of qi deficiency with blood stasis and dampness obstructing the qi mechanism. The disease location is in the spleen and stomach, affecting the heart and lungs. The nature is mixed deficiency-excess, with spleen qi deficiency as the root and damp obstruction with blood stasis as the branch. In terms of progression, if this constitution is not adjusted over a long period, qi and blood deficiency worsens, and the lip color may gradually progress from pale purple toward pallor. Typical symptoms include fatigue, poor appetite, abdominal distension after eating, heaviness in the body, and sticky, uncomfortable stools. The tongue is often pale purple, enlarged, with a thick white greasy coating; the pulse is soggy, thready, or moderate.
The spleen is the "source of qi and blood generation," and the lips are the "external reflection of the spleen." Pale purple lips are like flowers and grass growing on barren soil—lacking vitality and nourishment. This is not just a blood stasis problem, but a manifestation of insufficient "living water at the source." Therefore, the focus of regulation is not simply on invigorating blood, but on strengthening the spleen and promoting transformation, restoring the generation and distribution functions of qi and blood.
For dietary care, regular meals are an iron rule. Choose easily digestible, warm, and soft foods such as millet porridge, Chinese yam, and Poria cocos, in appropriate amounts and after consulting a professional physician. Avoid raw, cold, fatty, sweet, and greasy foods, which further trap spleen yang. For rest, take a short rest or walk slowly after meals; avoid immediate desk work or lying down. For emotions, excessive thinking damages the spleen, so do not overthink matters. For exercise and guidance, focus on strengthening core strength and promoting metabolism, such as stance standing or jogging, with the principle of slight body warmth and no fatigue. Care is only one part; truly adjusting your constitution requires comprehensive evaluation and direction established under the guidance of a licensed TCM practitioner.
Reading Yourself Through Lip Color, Starting Change with Daily Life
Carefully distinguishing these three lip colors—bluish-purple indicates cold, dark red indicates depression, and pale purple indicates deficiency—the direction of regulation differs for each and should not be treated uniformly. This is the exquisite nature of TCM's "treating the same disease with different methods," and it is also what makes it fascinating.
Whichever type it is, all point to sluggish movement of qi and blood. We might as well treat lip color as the dashboard of the body, looking in the mirror once every ten days. If you notice lip color deepening, recall your recent life: Have you been indulging in cold drinks? Have you been staying up late or feeling anxious? Has your diet been irregular? These seemingly trivial details of daily life are precisely the key valves for changing lip color.
Caring for the body has never been about a single herb or a single formula, but is integrated into daily diet, sleep, emotions, and breath. When you begin to pay attention to this small area of lip color, you have already stepped onto the long road of caring for your qi and blood. This road has no endpoint, but it is filled with awareness and peace along the way. May your lips always retain a warm, rosy glow, and may your heart remain free of stagnation and darkness.
