A clear runny nose is like a faucet that won't shut off—blow it and it comes back, wipe it and it still drips. Many people's first reaction is "I've caught a cold," so they hurry to drink ginger soup and bundle up under blankets to sweat it out. But strangely, sometimes the more they try to disperse the cold, the more the nose runs. What's going wrong here?
Question One: Is a Clear Runny Nose Always Cold?
Traditional Chinese medicine holds that "clear nasal discharge belongs to cold," and this is correct. But "cold" does not necessarily mean it must be dispersed. As the Huangdi Neijing states: "When water fluids in all diseases are clear, transparent, and cold, they all belong to cold."> However, cold is divided into excess and deficiency, and there is a distinction between external cold and internal cold.
External cold occurs when the weather turns cold, the nasal cavity is chilled, the pores close tightly, lung qi fails to diffuse, and nasal discharge flows out naturally. At this point, drinking something warm or soaking the feet can indeed bring relief. But if it is internal cold—where the body's own firepower is insufficient, yang qi is weak, and water fluids cannot be transformed and transported—then dispersing cold further is like adding frost to snow.
Question Two: Why Do Some People Get Worse the More They Warm the Yang?
In clinical practice, among those who constantly have a clear, watery runny nose that won't stop, some have an underlying constitution of "spleen-lung qi deficiency." The spleen governs the transformation and transportation of water-dampness, and the lung governs the regulation of water pathways. When spleen and lung function is weak, water fluids stagnate in the nasal orifices and become clear, thin nasal discharge.
If at this point one uses acrid-warm dispersing methods, it is like adding a roaring fire under a leaking pot—the steam rises and escapes even more through the gaps in the lid. In Chinese medicine, this is called "qi deficiency failing to contain," meaning qi cannot hold the water fluids; the more you disperse, the more deficient it becomes, and the more deficient it becomes, the more it flows.
Here there is an acupoint closely related to spleen-stomach transformation and transportation worth understanding—Zusanli. It is located on the anterolateral aspect of the lower leg, 3 cun below Dubi, one finger-breadth from the anterior crest of the tibia. It 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 says: "When pathogenic factors are in the spleen and stomach, there is muscle pain... all are regulated by Zusanli." In Chinese medicine theory, the stomach and spleen are interior-exteriorly related, and together they bear the responsibility of transforming and transporting water-dampness. As the He-Sea point of the Stomach Meridian, Zusanli is commonly used to regulate gastrointestinal function and has a certain connection to the impaired distribution of body fluids caused by spleen-lung qi deficiency. However, acupoint knowledge only helps us understand the body; specific treatment still requires syndrome differentiation by a licensed physician.
Question Three: Where Is the Fundamental Difference?
The real key is to distinguish "excess cold" from "deficient cold." Excess cold is like an ice block clogging a water pipe—melt it and it's fine; deficient cold is like a pipe that has aged and leaks—it needs repair, not vigorous pounding.
The Shanghan Lun mentions: "When disease presents with fever and aversion to cold, it arises from yang; when there is aversion to cold without fever, it arises from yin."> If, along with a clear runny nose, there is aversion to cold, cold hands and feet, mental fatigue, and loose stools, this is often deficient cold due to insufficient yang qi. For these individuals, simply dispersing cold is counterproductive.
When it comes to nasal orifice problems, two acupoints are frequently mentioned in Chinese medicine popular science. The first is Yingxiang, located beside the midpoint of the outer edge of the nasal wing, in the nasolabial groove. It belongs to the Hand Yangming Large Intestine Meridian and is the meeting point of the Hand and Foot Yangming. The Zhenjiu Jiayijing records: "For nasal congestion and inability to smell, blocked nasal passages and qi obstruction, Yingxiang governs it." The name of this point itself carries the meaning of "welcoming fragrance as it emerges," and it is closely related to the ventilating function of the nasal orifices. The other is Lieque, located on the radial edge of the forearm, above the radial styloid process, 1.5 cun above the wrist crease. It belongs to the Hand Taiyin Lung Meridian, is the Luo-Connecting point of the Lung Meridian, diverging to the Hand Yangming Large Intestine Meridian, and is also one of the eight confluent points, connecting to the Ren Mai. The Zhenjiu Dacheng states it can govern "nasal congestion and obstruction." The meridians to which these two acupoints belong are respectively interior-exteriorly related to the lung and large intestine. Chinese medicine theory holds that the lung opens into the nose, and the ventilation of the nasal orifices is closely related to the function of lung qi. Understanding these acupoints helps to better comprehend the holistic connection between "lung and nose."
Bringing It All Together: Don't Mistake "Nourishing Care" for "Treatment and Nourishing Care"
In Chinese medicine clinical practice, for the situation of a constantly clear, watery runny nose that won't stop, the first step is not to rush to give a solution, but to first assess the constitutional state. If it is deficient cold, the direction of care leans toward warming and supplementing the spleen and lung—for example, using mildly natured ingredients such as Chinese yam, red dates, and ginger (in moderation) to help the body generate its own yang qi. But the specific combination and duration of use need to be determined by a licensed Chinese medicine physician based on the individual's tongue coating and pulse presentation.
The Jingui Yaolüe says: "Those who treat disease before it arises—when seeing liver disease, know that the liver will transmit to the spleen, and should first fortify the spleen."> Regulating the body is not treating the head when the head hurts, but looking at the whole. A clear runny nose is just a signal; behind it may be a coordinated problem of the spleen, lung, and kidney systems.
The Wenbing Tiaobian also reminds us: "To treat the upper jiao is like a feather—without lightness it cannot be raised."> The nasal orifices belong to the upper jiao, and medicinal treatment should be light and agile, not crude and forceful. Ordinary people handling it themselves easily go to extremes.
So the next time a clear runny nose won't stop, first ask yourself: Is it shivering from cold, or exhausted and weak? If the direction is wrong, even the best method goes in the opposite direction. Nourishing the body requires a bit of Chinese medicine's "reading between the lines," and even more so a professional eye for syndrome differentiation.

Frequently Asked Questions
Q: What is the essential difference between clear and turbid nasal discharge in Chinese medicine?
A: Clear discharge mostly belongs to cold and deficiency, while turbid discharge mostly belongs to heat and excess. Clear and watery indicates insufficient yang qi or external cold binding the exterior; thick and yellow suggests heat pathogen or internal accumulation of damp-heat. However, clinically there are also cases of mixed cold and heat, so it cannot be generalized.
Q: Why do some people have a clear runny nose but also a sore throat?
A: This may be a presentation of "external cold with internal heat" or "upper heat and lower cold." On the surface, cold pathogen binds the exterior, but internally there is stagnant heat, or deficiency cold in the lower jiao causes deficient fire to float upward. Treatment needs to address both clearing the upper and warming the lower, and one should not focus only on the nasal discharge.
Q: Is a clear runny nose from staying in an air-conditioned room for a long time the same as catching cold?
A: Not exactly the same. The cold air from air conditioning is "artificial cold," which easily damages the yang qi of the body surface. But if it is not accompanied by whole-body aversion to cold and fatigue, it is more a case of lung qi being constrained. Appropriate activity, drinking warm water, and avoiding direct blowing are more important than eating warm-natured foods.
Q: Why do some people with the same clear runny nose need warming supplementation while others need cold dispersion?
A: This reflects Chinese medicine's principle of "treating the same disease differently." Different constitutions mean different pathomechanisms. When a young person suddenly catches a chill, it is mostly excess cold; when an elderly person or someone chronically overworked has it, it is mostly deficient cold. A licensed Chinese medicine physician will use inspection, auscultation and olfaction, inquiry, and palpation to determine whether "pathogenic qi is exuberant" or "righteous qi is deficient," and then decide the direction.
