Prunella vulgaris & Artemisia capillaris: Gallbladder-Draining Soup

Introduction to Medicinal Food

Prunella and Artemisia Gallbladder-Draining Decoction is a classic medicinal dietary formula derived from the traditional Chinese medicine theory of liver-gallbladder regulation. It is prepared with Prunella vulgaris (self-heal) and Artemisia capillaris (yin chen) as the core herbs, combined with lean pork or pork ribs. Prunella vulgaris is cold in nature, bitter and pungent in taste, and enters the Liver (LR) and Gallbladder (GB) meridians. It excels at clearing liver fire, dispersing nodules, and reducing swelling. Artemisia capillaris is slightly cold in nature, bitter and pungent in taste, and enters the Liver, Gallbladder, and Spleen (SP) meridians. It is a key herb in TCM for treating jaundice and damp-heat accumulation in the liver and gallbladder. When combined, these two herbs effectively clear liver-gallbladder damp-heat and unblock gallbladder qi. Supplemented with meat to adjust the flavor and provide nourishing properties, this soup possesses dual value of medicinal efficacy and dietary nourishment. This formula has been widely circulated among the folk in the Lingnan and Jiangzhe regions. It is especially suitable during the late spring and early summer season when damp-heat is prevalent, as well as for individuals suffering from liver-gallbladder disharmony caused by long-term greasy diet and irregular lifestyle.

This decoction is named “Li Dan Tang” (Bile-Promoting Decoction) to highlight its core actions of promoting bile secretion and excretion, thereby reducing hepatobiliary pressure. Modern nutritional studies have also found that *Prunella vulgaris* (Selfheal) contains prunellin and triterpenoids, while *Artemisia capillaris* (Virgate Wormwood) is rich in chlorogenic acid and volatile oils. These bioactive substances act synergistically to improve hepatic microcirculation and suppress inflammatory responses, thereby achieving a comprehensive hepatoprotective and cholagogic effect. As a simple and conveniently prepared medicinal diet with few ingredients, it can be used not only for daily preventive healthcare but also as an adjunctive therapy for conditions such as chronic cholecystitis and impaired bile excretion.

Efficacy of Medicinal Diet

Draining the gallbladder and expelling turbidity, as well as clearing and draining damp-heat, are the primary actions of this decoction. Artemisia capillaris (Yinchen) significantly promotes bile secretion, increasing the excretion of bile acids and bilirubin, thereby helping to dilute bile and prevent cholesterol deposition—beneficial for both the prevention and supportive recovery of cholecystitis and gallstones. Prunella vulgaris (Xiakucao) excels at clearing liver fire and dispersing constraint, providing direct relief for symptoms such as a bitter taste in the mouth, distension and pain in the hypochondrium, and irritability caused by liver-gallbladder depression-heat.

In addition, this decoction demonstrates notable effects in protecting the liver, lowering enzyme levels, and providing anti-inflammatory and antioxidant actions. Both medicinal herbs in the formula possess strong anti-inflammatory activity, capable of inhibiting hepatocellular injury and reducing serum aminotransferase levels, thereby offering benefits in managing alcoholic liver injury and early-stage fatty liver disease. When consumed in moderation over the long term, it also helps regulate blood lipids and improve digestive function, restoring the liver and gallbladder system to a healthy state of smooth and orderly descending.

comprehensive health care aspect

This formula not only alleviates the burden on the Liver and Gallbladder but also indirectly regulates emotions and sleep by dredging and discharging Liver-Gallbladder qi. According to TCM, “the Liver governs free coursing and discharge”; when Liver and Gallbladder functions are smooth, the emotions are relaxed, and qi and blood are harmonized. Therefore, Xiakucao Yinchen Lidan Decoction (Prunella vulgaris and Artemisia capillaris Gallbladder-Benefiting Decoction) also improves sub-health conditions such as liver fire hyperactivity and shallow sleep caused by high work stress and frequent熬夜. It possesses dual actions of “clearing the Liver” and “calming the mind.”

The role of Traditional Chinese Medicine

From the perspective of Traditional Chinese Medicine’s properties, flavors, and meridian affinities, *Xiakucao* (*Prunella vulgaris*, Selfheal) is bitter and pungent in flavor, cold in nature, and specifically enters the Liver (LR) and Gallbladder (GB) meridians. Its bitterness drains heat, while its pungency disperses nodules; thus, it can clear the Liver and brighten the eyes, as well as scatter stagnation and reduce swelling. *Yinchen* (*Artemisia capillaris*, Capillary Wormwood) is bitter and pungent in flavor, slightly cold in nature, and enters the Liver (LR), Gallbladder (GB), and Spleen (SP) meridians. It is considered the “primary herb for treating jaundice” and is especially adept at clearing and draining damp-heat from the Spleen, Stomach, Liver, and Gallbladder, as well as unblocking the Gallbladder channel. When combined, their cold-bitter properties synergistically amplify, making the actions of clearing heat and draining dampness, as well as soothing the Liver and regulating the Gallbladder, more focused and powerful.

The composition of this decoction aligns with the principle that “Fu-organ disorders are treated by promoting patency.” The gallbladder, as one of the six Fu organs, functions optimally when it is unobstructed and qi descends smoothly. The combined use of Prunella vulgaris (Common Selfheal) and Artemisia capillaris (Virgate Wormwood) can both clear and resolve stagnant heat in the gallbladder and promote normal bile excretion, thereby restoring the gallbladder’s descending and draining function. In response to modern lifestyle patterns such as high-fat diet, sedentary behavior, and emotional frustration, this formula, by clearing and draining damp-heat from the Liver and Gallbladder and harmonizing qi movement, effectively prevents the onset and progression of conditions such as “Gallbladder Distension,” “Hypochondriac Pain,” and “Jaundice.”

Indications

This decoction is most suitable for individuals with a Liver and Gallbladder Damp-Heat constitution. Common manifestations include: bitter taste in the mouth, dry throat, distension or dull pain in both hypochondriac regions, poor appetite, a yellow, thick, and greasy tongue coating, scanty and dark yellow urination, sticky and unsatisfying bowel movements, or findings from physical examinations such as mild fatty liver, a roughened gallbladder wall, or cholestasis. For those who habitually consume spicy and greasy foods, frequently drink alcohol, or often stay up late, this decoction can serve as a stage-based health maintenance formula, helping the body to “clear fire and eliminate toxins.”

In addition, patients with chronic cholecystitis or cholelithiasis in non-acute episodes, as well as those in the recovery phase of chronic hepatitis presenting with damp-heat and vexation, may take this decoction in moderation under medical guidance to support recovery. For the general population prone to symptoms such as dizziness and heaviness in the head, sluggish body, greasy skin, and acne due to “internal accumulation of damp-heat” during spring or the long summer period, this decoction also serves as a seasonal therapeutic food for clearing heat and cooling.

Contraindicated Populations

People with Spleen and Stomach Deficiency Cold pattern should use this decoction with caution or avoid it altogether. The medicinal properties of this formula are relatively cold and cool. If the patient typically presents with manifestations such as epigastric cold pain, preference for warmth and pressure, loose stools, cold extremities, and a pale, enlarged tongue with teeth marks on the edges, consuming it may aggravate the deficiency cold symptoms, leading to diarrhea or abdominal discomfort. If such individuals need to regulate the Liver and Gallbladder, it is recommended to combine with warming the middle medicinals such as Rhizoma Zingiberis (dried ginger) and Fructus Jujubae (jujube) under the guidance of a TCM practitioner to moderate the medicinal properties.

Pregnant and breastfeeding women should not take this decoction without professional guidance. Both Prunella vulgaris (Xiakucao) and Artemisiae Scopariae Herba (Yinchen) are cold-natured herbs with blood-activating and meridian-dredging properties, which may affect the fetus or newborn. Children, the elderly, and those with weak constitution must strictly control the dosage or follow a physician’s instructions before use. In addition, during an acute episode of cholecystitis with symptoms such as severe right upper quadrant pain, fever, and worsening jaundice, this decoction should not be used as a treatment; immediate medical attention is required.

Proportion of ingredients in a formula

15g Prunella vulgaris (selfheal), 20g Artemisia capillaris (yin chen hao), 300g lean pork or pork ribs, 3 slices ginger, 2 red dates (jujube), 1 candied date (optional), and 2000ml water. This recipe serves 2–3 people, and can be proportionally adjusted according to the number of servings. The ratio of Prunella to Artemisia is approximately 3:4, which ensures the effect of promoting bile secretion and clearing heat while avoiding an overly bitter taste that might affect palatability.

Ingredient Analysis: For Prunella vulgaris (common self-heal), select specimens with long spikes, brownish-black color, and light weight. For Artemisia capillaris (capillary wormwood), choose tender, leafy, grayish-green material with a strong aroma. Lean pork or pork ribs serve as the base, absorbing the bitterness of the herbs while providing a rich, savory broth. Fresh ginger (Zingiber officinale) and Chinese jujube (Ziziphus jujuba) are added to harmonize the medicinal properties and mitigate the cold nature of Prunella vulgaris and Artemisia capillaris, which could otherwise impair the stomach. Candied dates (honey dates) are used to improve the soup’s color and sweetness, making it particularly suitable for beginners or children.

Preparation Method

Step 1: Quickly rinse the Prunella vulgaris (self-heal) and Artemisia capillaris (yin chen) in warm water once to remove dust, then soak in clean water for 15 minutes. Cut lean pork or pork ribs into pieces. Place them in a pot with cold water, add two slices of ginger, bring to a boil over high heat, skim off the foam, blanch for about 3 minutes, remove, and rinse with warm water. Set aside.

Step 2: Take an earthenware pot or ceramic casserole, pour in 2000 ml of clear water. Bring to a boil over high heat, then add the blanched meat pieces, the soaked Prunella vulgaris (common selfheal) and Artemisia capillaris (capillary wormwood) along with the soaking water, the remaining ginger slices, Jujube dates (Chinese red dates), and honey dates. When it returns to a boil, reduce to low heat, maintain a gentle simmer, cover with a lid, and slow-cook for 1.5 hours.

Step 3: When the meat becomes tender and falls off the bone, and the broth turns a light tea color with a rich medicinal aroma, use a fine-mesh strainer or cheesecloth to remove the herbal residue, retaining only the clear soup and meat pieces. Season with a pinch of salt to taste (suggested no more than 2 grams), stir well, then turn off the heat. Serve warm in a bowl, 200–300 ml per serving, once daily. A course of 3–5 consecutive days is recommended.

Administration Tips

1. The optimal consumption times are between 9–11 am (Sì Shí, the period when the Spleen Meridian is active) or 3–5 pm (Shēn Shí, the period when the Bladder Meridian is active). During these two time slots, the body’s yang qi is abundant, which better facilitates the transportation and transformation of the medicinal effects and the drainage of damp-heat, while avoiding evening consumption that may increase nocturia frequency.

2. The medicinal soup should be consumed warm, and must not be taken cold or reheated after overnight storage, to avoid cold damaging the Stomach or promoting bacterial growth. If a large batch is prepared, the strained clear soup can be sealed and refrigerated, but it must be reheated and consumed within 24 hours, and the reboiling time should not exceed 3 minutes.

3. During the treatment period, a light diet is recommended. Reduce consumption of fried, grilled, greasy, sweet, and rich foods, and abstain from alcohol. At the same time, increase intake of vegetables and high-quality protein. Ingredients such as wax gourd (Benincasa hispida), white radish (Raphanus sativus), and celery (Apium graveolens) can be added to help drain dampness and soothe the Qi, thereby enhancing the overall regulating effect. If persistent diarrhea or significant stomach discomfort occurs after consumption, discontinue use and consult a TCM professional.
