Have you ever had this experience? Diarrhea is like a leaking pipe—several times a day, watery stools gushing out, and your whole body feels drained of energy. Behind this is actually a problem with your body's internal fluid metabolism. In TCM clinical practice, this kind of watery stool is commonly seen in spleen-stomach dysfunction and rampant dampness—just like a pipe that is blocked or has imbalanced pressure, water escapes uncontrollably. Don't rush to just think about stopping the diarrhea; we first need to look at where the "water" is coming from.
Myth One: Diarrhea Means You Ate Something Bad—Take Antidiarrheal Medicine Right Away
Many people assume that diarrhea is caused by unclean food and immediately reach for antidiarrheal medication. But watery stools several times a day are sometimes not due to bacterial infection, but rather spleen-stomach weakness or excessive dampness. For example, long-term irregular eating habits and a preference for cold foods and drinks can leave the spleen and stomach like an exhausted water pump, unable to properly transform and transport water-dampness. Dampness then seeps into the intestines, forming watery stools. Blindly stopping the diarrhea may instead "trap" dampness inside the body, causing abdominal bloating or even longer-lasting diarrhea.
TCM Perspective: Diarrhea is the body's cry for help while "draining water." Watery stools are commonly seen in people with spleen deficiency and exuberant dampness, or cold-dampness encumbering the spleen—just like a leaking pipe, you need to first clear the blockage or reinforce the pipe walls, not just plug the outlet. Clinically, it is necessary to distinguish whether it is insufficient transforming and transporting capacity of the spleen and stomach, or invasion of external dampness. If it is spleen deficiency, it is often accompanied by fatigue and poor appetite; if it is cold-dampness, there is often aversion to cold and borborygmus. The treatment directions differ—the former focuses on fortifying the spleen, while the latter focuses on dispersing cold and transforming dampness.
From the perspective of TCM meridian theory, Zusanli is an important acupoint for regulating spleen-stomach function. Zusanli, also known as Xialing or Sanli, 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 records: "When pathogenic factors are in the spleen and stomach, there is muscle pain... all are regulated by Zusanli," indicating its close relationship with spleen-stomach transformation and transportation. In TCM clinical practice, it is often used as one of the reference acupoints for regulating spleen-stomach issues.
Myth Two: Diarrhea Requires Salt Water for Rehydration—The Saltier, the Better
Many health articles say that diarrhea requires salt water supplementation, but some people drink it with excessive saltiness, which actually worsens the watery stools. In TCM, salty flavor enters the kidney, and excess will damage the kidney, while the kidney governs water-fluid metabolism. When there are watery stools several times a day, the body's water-fluid balance is disrupted, but simply adding salt may disturb electrolyte balance and even increase the burden on the kidneys. More critically, if the spleen and stomach are already weak, salty flavor will irritate the intestines, leading to more frequent diarrhea.
TCM Perspective: Rehydration needs to be gentle. Traditional TCM suggests that an appropriate amount of rice water or lightly salted water may be consumed. Rice water can fortify the spleen and nourish the stomach, helping with water-fluid absorption. However, when watery stools are severe, a licensed TCM practitioner needs to determine based on individual constitution whether to use warming supplementation or clearing transformation. For example, for cold-dampness type diarrhea, drinking ginger and brown sugar water can help warm the middle and disperse cold; for damp-heat type, ingredients that clear heat and drain dampness may be needed, such as an appropriate amount of purslane. Blindly adding salt is like increasing water pressure on a leaking pipe—it only makes the problem worse.
Myth Three: Diarrhea Means Dampness Is Severe—Eat More Job's Tears to Remove Dampness
The claim that Job's tears (coix seed) removes dampness is very popular, but when there are watery stools several times a day, eating Job's tears directly may be counterproductive. Job's tears is cool in nature, and for people with spleen-stomach deficiency-cold and clear watery stools, it adds cold upon cold, actually worsening the diarrhea. For example, some people feel cold and have cold hands and feet during diarrhea—this belongs to cold-dampness, and Job's tears is not quite suitable. Dampness has cold-dampness and damp-heat distinctions, and the color, odor, and accompanying symptoms of watery stools all differ.
TCM Perspective: To remove dampness, first distinguish cold from heat. Clear, thin, odorless watery stools with aversion to cold mostly belong to cold-dampness and require warming transformation, such as using warm-natured ingredients like dried ginger and cinnamon; yellow, foul-smelling watery stools with burning sensation at the anus mostly belong to damp-heat, and clearing heat and draining dampness may be considered, such as using mung beans and winter melon. Clinically, if accompanied by fever and vomiting, it may be acute gastroenteritis, and simple dampness removal is not appropriate—prompt medical attention is needed. Remember, removing dampness is not a "master key"—you need to see which lock this key opens.
Yinlingquan is also an acupoint related to water-dampness metabolism. Yinlingquan is located in the depression between the lower border of the medial condyle of the tibia and the medial border of the tibia on the medial side of the lower leg. It belongs to the Foot Taiyin Spleen Meridian and is the He-Sea point of the Spleen Meridian. TCM holds that the spleen governs the transformation and transportation of water-dampness, and Yinlingquan is a commonly used acupoint for regulating water-dampness transformation and transportation. The Zhenjiu Dacheng states it can treat "difficult urination" and other water-dampness related conditions. Understanding these acupoints helps in comprehending TCM's understanding of watery stools, but specific diagnosis and treatment require consultation with a licensed TCM practitioner.
Summary: Diarrhea—several times a day, watery stools—is like a leaking pipe, with the root cause in the balance between the "pipe walls" and "water flow." The spleen and stomach are the pipe walls, dampness is the water flow, and cold-heat is the water temperature. In TCM clinical practice, regulating watery stools requires first determining whether it is spleen deficiency, exuberant dampness, or mixed cold-heat. For example, people under long-term stress and with irregular eating habits may primarily have spleen deficiency; those who develop symptoms after exposure to cold may have predominant cold-dampness. Each person's constitution is different, so the treatment direction naturally differs. Don't rush to apply a "universal formula"—consult a licensed TCM practitioner at a licensed medical institution and let professional judgment help you find the "leak point." Nourishing the spleen and stomach starts with daily diet and lifestyle habits—such as eating fewer cold and raw foods and maintaining regular sleep—so that your body's pipes can remain as sturdy as ever.
Frequently Asked Questions
1. What is the difference between watery stools and ordinary diarrhea?
Watery stools refer to stool that is thin and water-like, occurring multiple times a day with high water content; ordinary diarrhea may just be loose stool or increased frequency. Watery stools are more commonly seen in spleen-stomach transformation and transportation dysfunction or acute infection, and TCM requires distinguishing cold, heat, deficiency, and excess.
2. Why do some people use warming supplementation for diarrhea while others use clearing purgation?
This depends on constitution and cause. Deficiency-cold type diarrhea (such as aversion to cold, preference for warmth) requires warming supplementation; damp-heat type (such as burning at the anus, foul-smelling stool) requires clearing purgation. TCM treats the "same disease with different methods" and cannot be generalized.
3. What should I pay attention to in my diet during diarrhea?
It is recommended to focus on light, easily digestible foods such as millet porridge and steamed Chinese yam. Avoid cold, raw, greasy, and spicy irritants, as these will increase the burden on the spleen and stomach. For specifics, consult a licensed TCM practitioner.
4. If watery stools recur, does it mean there is a chronic problem in the body?
Recurrent watery stools may indicate spleen-stomach weakness or intestinal flora imbalance, and may also be related to emotional stress. TCM holds that "liver wood overacts on spleen earth," and emotional distress can also affect digestion. Long-term regulation is recommended rather than temporary diarrhea suppression.
