Early in the morning, a middle-aged man walked into the consultation room, rubbing his sleepy eyes. His first words were: "Doctor, my eyes — every morning they're so crusted over I can barely open them. The eye discharge is alarming. Is it 'internal heat'?" As he spoke, he wiped the corners of his eyes with a tissue, his expression a mix of confusion and helplessness. This scene is not uncommon in TCM clinics. When many people notice increased eye discharge, their first reaction is "too much fire." But where does this "fire" actually come from? Is it liver fire, stomach fire, or something else entirely? Today, let's discuss this seemingly minor issue that troubles quite a few people.
What Do the Classics Say? — Organ Signals Behind Eye Discharge
The Huangdi Neijing, Lingshu, Chapter on Great Confusion states: "The essential qi of the five zang and six fu organs all ascends and pours into the eyes, forming their essence."
This passage tells us that the eyes are not isolated organs but rather gathering places for the essential qi of the five zang and six fu organs. Eye discharge, as a secretion of the eyes, reveals the state of the internal organs through its quantity, texture, and color. In TCM clinical practice, increased eye discharge often indicates a problem of "heat" or "dampness," but which organ's "heat" it is, and whether it is excess or deficiency, must be differentiated.
Clinically, waking up with particularly heavy eye discharge that glues the eyes shut is seen mostly in two types of people: first, those with relatively exuberant liver fire, often accompanied by red eyes, bitter taste in the mouth, and irritability; second, those with dampness-heat in the spleen and stomach, who typically have sticky eye discharge, heavy eyelids, and a sticky sensation in the mouth. The treatment directions for these two are completely different — if one indiscriminately clears fire without distinguishing between them, it may actually damage healthy qi.
How to Distinguish Liver Fire from Stomach Fire?
Since excessive eye discharge is often related to "fire," is this fire liver fire or stomach fire? How do they differ?
In people with exuberant liver fire, eye discharge is mostly yellow or yellow-green, relatively dry in texture, and prone to forming crusts. Upon waking in the morning, they often feel dryness and redness in the eyes, sometimes accompanied by dizziness, tinnitus, and irritability. These individuals often stay up late chronically, overuse their eyes, or experience emotional constraint, leading to stagnation of liver qi that transforms into fire.
In TCM theory, the Foot Jueyin Liver Meridian has an important acupoint — Taichong, also known as Dachong, which belongs to the Foot Jueyin Liver Meridian and is the Yuan-Source point of the Liver Meridian. The Lingshu, Chapter on Nine Needles and Twelve Yuan states: "When the five zang have diseases, one should select from the twelve yuan points." Taichong is located on the dorsum of the foot, in the depression anterior to the junction of the first and second metatarsal bones, and is where the qi and blood of the Liver Meridian gather. Pathological changes such as liver qi stagnation transforming into fire are often reflected at this point, so Taichong is commonly used in TCM pattern differentiation as one of the reference acupoints for assessing whether liver qi is flowing smoothly.
Eye discharge caused by dampness-heat in the spleen and stomach, on the other hand, is mostly white or pale yellow, sticky in texture, gluing the eyes shut like glue, with heavy eyelids and difficulty opening the eyes. These individuals often have a sticky sensation in the mouth, poor appetite, and sticky, uncomfortable bowel movements. This is mostly due to irregular eating habits, excessive consumption of rich, greasy, and sweet foods, or prolonged exposure to damp environments, leading to internal accumulation of dampness-heat.
Clinically, if some individuals also present with red, swollen eyelids and photophobia with tearing, it may belong to "wind-heat external attack," and should not be treated by simply clearing and draining alone — a licensed TCM practitioner should determine the treatment plan after pattern differentiation.
How Is Excessive Eye Discharge Related to Daily Habits?
Why is it that in the same season, some people have normal eye discharge while others can barely open their eyes? Behind this, lifestyle habits are key.
Chronic late nights and excessive eye use most easily consume and damage liver blood. When liver blood is insufficient, deficiency fire flares upward, and eye discharge naturally increases. TCM has the saying "prolonged gazing damages blood." Modern people staring at phones and computers all day are essentially "overdrawing" their liver blood.
Dietarily, a preference for spicy, fried, and grilled foods will fuel stomach fire, while a predilection for sweets and greasy foods easily generates dampness-heat. Both types of dietary preferences can lead to increased eye discharge.
Furthermore, significant emotional fluctuations and high stress can also easily cause liver qi to become unsmooth, stagnating and transforming into fire. Clinically, the problem of increased eye discharge is relatively common among people who are in prolonged states of tension and anxiety, often accompanied by insomnia, headaches, and other manifestations.
What Details Can Be Addressed in Daily Care?
Since increased eye discharge reflects an internal imbalance, daily care should also start with addressing these imbalances.
For those with a tendency toward exuberant liver fire, the diet can appropriately include more light, cool, and moistening ingredients, such as mung bean sprouts, celery, and bitter melon, which help clear liver fire. At the same time, avoid staying up late — try to fall asleep before 11 PM so that liver blood can return and be stored.
For those with a tendency toward dampness-heat in the spleen and stomach, reduce the intake of greasy, sweet, and cold foods, and appropriately eat more ingredients that help drain dampness, such as winter melon and coix seed. Maintain regular eating habits and avoid overeating.
When it comes to spleen and stomach regulation, Zusanli is an acupoint that cannot be overlooked. Zusanli, also known as Xialing or Sanli, belongs to the Foot Yangming Stomach Meridian and is the He-Sea point of the Stomach Meridian and the lower He-Sea point of the Stomach. The Lingshu, Chapter on Pathogenic Qi and Zang-Fu Manifestations states: "He points treat the internal fu organs." Zusanli is located on the anterior-lateral aspect of the lower leg, 3 cun below Dubi, one transverse finger-breadth from the anterior crest of the tibia. In TCM theory, Zusanli is closely related to the transforming and transporting functions of the spleen and stomach, often used as an important acupoint reflecting the abundance or decline of qi and blood in the middle jiao, and is one of the commonly used acupoints by the ancients for regulating the spleen and stomach and supporting healthy qi.
Regardless of the type, maintaining eye hygiene is important. However, be careful not to rub the eyes with your hands, to avoid aggravating inflammation. If eye discharge is excessive and accompanied by obvious discomfort, it is recommended to consult a licensed medical institution and have a licensed TCM practitioner provide specific recommendations after pattern differentiation.
How Does Eye Discharge Differ Across Seasons?
The underlying causes of increased eye discharge vary slightly across different seasons.
In spring, liver qi is in command. If liver qi rises and disperses too vigorously, it easily causes fire, increasing eye discharge. At this time, one may appropriately consume seasonal wild vegetables such as dandelion and shepherd's purse, which help clear the liver and brighten the eyes.
In summer, summerheat and dampness tend to be excessive. If the spleen and stomach's transforming and transporting functions are insufficient, dampness-heat accumulates internally, and eye discharge tends to be sticky. At this time, one may appropriately consume foods that clear summerheat and drain dampness, such as mung bean soup and lotus leaf congee.
In autumn, dryness qi is in command. If yin fluids are insufficient and deficiency fire flares upward, eye discharge may tend to be dry. At this time, attention should be paid to nourishing yin and moistening dryness, and one may appropriately consume lily bulb, white fungus, and similar ingredients.
In winter, cold pathogens bind the exterior. If there is internal constrained heat, it may also lead to increased eye discharge. At this time, excessive tonification should be avoided to prevent fueling fire.
Increased eye discharge may seem like a minor matter, but it is actually the body "speaking." Is it liver fire, stomach fire, dampness-heat, or yin deficiency? Different constitutions require vastly different treatment directions. TCM emphasizes "treating the same disease with different methods." For the same excessive eye discharge, some people need clearing and draining, while others need warming and tonifying — they cannot be treated uniformly.
Have you also been troubled by crusted eyes and eye discharge upon waking? Take a moment to calm down and observe whether your eye discharge is dry or sticky, yellow or white, and then consider your diet, sleep schedule, and emotions — perhaps you will find your body's "point of imbalance." The way of health preservation values consistency in the ordinary.

Frequently Asked Questions
Q1: Is excessive eye discharge the same as "internal heat"?
Not entirely equivalent. In TCM, "internal heat" has both excess and deficiency types. Excessive eye discharge may arise from excess fire (such as liver fire or stomach fire), or from deficiency fire (such as yin deficiency with fire flaring), or from internal accumulation of dampness-heat. Blindly clearing fire may damage healthy qi and requires pattern differentiation.
Q2: Why do some people with excessive eye discharge need clearing and draining, while others need warming and tonifying?
Because constitutions differ. Those with exuberant liver fire need clearing and draining; those with dampness-heat in the spleen and stomach need to drain dampness; and those with spleen-stomach deficiency cold combined with dampness-heat need to warm the middle while also clearing. TCM emphasizes "treating according to the individual," and treating the same disease with different methods is precisely its essence.
Q3: Does excessive eye discharge mean the eyes are inflamed?
Not necessarily. Increased eye discharge may be a manifestation of ocular inflammation, such as conjunctivitis, or it may be a local reflection of a systemic imbalance. If accompanied by redness, swelling, pain, or decreased vision, medical attention should be sought promptly.
