Eclipta and Imperata Root Lean Meat Soup: Medicinal Benefits & Recipe

Introduction to Medicinal Cuisine

Eclipta and Imperata Root Lean Meat Soup is a traditional medicinal food originating from the Lingnan region, known for its dual properties of clearing-moistening and supplementing-nourishing. It features Eclipta prostrata (also known as Hanliancao or Mojiecao) and Imperata cylindrica (Baimaogen) as the core herbal ingredients, supplemented with lean pork and slow-cooked to infuse the medicinal properties into the broth. According to the *Bencao Gangmu* (Compendium of Materia Medica), Eclipta is recorded as a substance that “blackens hair and beard and nourishes kidney yin,” while Imperata root is commonly used to clear lung and stomach heat, promote urination, and cool the blood. The former excels in nourishing the liver and kidney, and the latter specializes in clearing and dispelling blood heat. When harmonized with lean meat soup, they form a sweet, neutral, clearing-moistening medicinal recipe that is neither cold nor stagnating.

This soup is especially common in southern regions during the transition from spring to summer or in the dry autumn season. Due to the interweaving of damp-heat and dry-heat climates, the human body is prone to manifestations of “Blood-Heat,” such as dry mouth, dark yellow urine, and skin sores. The *Ecliptae Herba* (Eclipta) and *Imperatae Rhizoma* (Cogongrass Rhizome) Lean Pork Soup is precisely characterized by its property of “clearing without attacking, and tonifying without greasiness,” making it a family-oriented medicated dietary option for daily regulation. The soup has a clear, slightly brown broth, with a light herbal fragrance and meaty freshness on the palate. It can be used as an auxiliary remedy for certain mild heat-related discomforts, as well as a health-preserving soup during seasonal transitions.

Therapeutic Effects of Medicinal Diet

The core efficacy of the Eclipta and Cogongrass Lean Meat Soup can be summarized as “clearing heat and cooling blood, nourishing yin and moistening dryness.” Specifically, Imperata cylindrica (Cogongrass rhizome) enters the Lung (LU), Stomach (ST), and Bladder (BL) meridians, excelling at clearing and venting internal heat, generating fluids to quench thirst, and guiding pathogenic heat out through urination. Eclipta prostrata (Eclipta) focuses on nourishing Liver and Kidney yin, while also possessing the ability to cool blood and stop bleeding. It provides significant relief for symptoms such as dry mouth and tongue, swollen gums, and a tendency for red rashes or small sores on the skin caused by yin deficiency with blood heat. Together, these two herbs synergize to clear stagnant heat in the body while nourishing yin fluids, thereby correcting the imbalance of “fire in the Upper Jiao and deficiency in the Lower Jiao.”

Furthermore, lean meat, as a “substance of blood and flesh,” can tonify the Spleen and Stomach, nourish Qi and Blood, ensuring that the soup supports the Right (Zheng) Qi while clearing and draining. Overall, this soup is beneficial for alleviating seasonal discomforts such as Liver fire hyperactivity in spring, summer heat damaging body fluids, and autumn dryness-heat causing cough. It also helps improve suboptimal health conditions like deficiency-fire ascending and scanty dark urine after staying up late or consuming spicy foods. With long-term moderate consumption, it helps maintain the balance of Yin and Yang, keeping the skin moist and breath fresh.

The Role of Traditional Chinese Medicine

From the perspective of TCM property, flavor, and meridian tropism theory, Eclipta prostrata (Eclipta) has sweet and sour flavors, cool nature, and enters the Liver (LR) and Kidney (KI) meridians. Its main actions are to nourish Liver and Kidney yin and cool blood to stop bleeding. Imperata cylindrica (Imperata root) has sweet flavor, cold nature, and enters the Lung (LU), Stomach (ST), and Urinary Bladder (BL) meridians. It specializes in clearing heat, generating fluids, promoting urination, and treating strangury. The combination of these two herbs forms a pattern where one emphasizes ‘nourishing’ and ‘astringing’, and the other emphasizes ‘clearing’ and ‘promoting’, creating a therapeutic effect pattern of ‘clearing the upper and nourishing the lower, cooling blood without causing stasis’. The lean meat in the soup has sweet and salty flavors, neutral nature, and enters the Spleen (SP), Stomach (ST), and Kidney (KI) meridians. It can supplement the middle and boost qi, nourish yin and moisten dryness, providing a middle jiao transportation and transformation foundation for the medicinal actions.

In terms of specific pathological mechanisms, this soup is particularly suitable for individuals with TCM patterns of “Yin Deficiency with Blood Heat” or “Lung and Stomach Accumulated Heat”. Those with Yin Deficiency and Blood Heat often present with heat in the palms and soles, dry mouth and throat, night sweats, and a red tongue with scant coating. Those with Lung and Stomach Accumulated Heat frequently exhibit thirst with a preference for cold drinks, halitosis, swollen and painful gums, and yellow turbid urine. The Eclipta and Imperata Lean Pork Soup works by nourishing Yin to control deficiency fire, clearing heat to remove excess fire, and utilizing the diuretic action of Imperata (Imperata cylindrica) to provide an outlet for pathogenic factors, allowing heat to be dispersed from the Lower Burner. This achieves a therapeutic effect of “clearing without damaging the right, and tonifying without promoting fire.”

Essentials of Medicinal Pair Compatibility

The combination of *Eclipta prostrata* (Eclipta) and *Imperata cylindrica* (Imperata) is a classic drug pair in Chinese herbal formula theory, representing the “clearing and nourishing used together” approach. *Eclipta prostrata*, supported by *Imperata cylindrica*, enhances its blood-cooling ability without causing the nourishing of yin to obstruct the stomach; *Imperata cylindrica*, assisted by *Eclipta prostrata*, clears heat without excessive coldness that would damage yang. They complement each other, allowing the entire medicinal dietary preparation to both purge heat pathogens and protect the yin fluids. This combination is particularly suitable for individuals with complex constitutions presenting both heat signs and yin deficiency.

Indications

The first suitable group consists of adults who frequently stay up late, experience high work pressure, or consume excessive spicy, grilled foods, alcohol, or tobacco. This group commonly presents with symptoms of “excessive heat” such as dry mouth and tongue, recurrent oral ulcers, facial acne, and dark yellow urine, which are essentially due to yin deficiency with fire hyperactivity or internal accumulation of blood heat. The soup of Eclipta prostrata (旱莲草) and Imperata cylindrica (茅根) with lean pork, which nourishes yin and cools blood, can effectively alleviate these symptoms and help the body restore balance.

The second suitable population is adolescents in puberty, particularly those with recurrent acne on the face and back due to internal exuberance of blood-heat, accompanied by dry stool, yellowish urine, and a red tongue. This soup can clear and outthrust blood-heat from the interior, moisten and nourish the skin. As a supplementary soup for daily regulation, it helps reduce the inflammatory response of acne. Moreover, it is free from medicinal hormones and is relatively safe.

The third suitable group is menopausal women. During this stage, women often suffer from tidal heat and sweating, irritability and insomnia, dry mouth and throat, as well as dry and itchy skin due to Liver and Kidney Yin Deficiency with Deficiency Fire Harassing Internally. *Eclipta prostrata* (Eclipta herb) nourishes the Yin of the Liver and Kidneys, combined with *Imperata cylindrica* (Cogongrass rhizome) to clear and disperse Deficiency Heat, while the lean meat soup supplements and boosts Qi and Blood. This combination can effectively improve the pattern of Yin Deficiency with Blazing Fire during menopause, helping to smoothly navigate this special physiological period.

Contraindicated Populations

Patients with Spleen-Stomach Deficiency Cold should use this soup with caution or avoid it altogether. Ecliptae Herba (旱莲草, eclipta) is cool in nature, while Imperatae Rhizoma (白茅根, cogongrass rhizome) is cold; when combined, they render the overall soup cold and cooling in property. Individuals who typically present with Spleen Yang deficiency signs—such as epigastric cold pain that is relieved by warmth and pressure, loose stools or undigested food in the stool, a bland taste in the mouth without thirst, etc.—may experience aggravation of deficiency cold symptoms after consumption, potentially leading to diarrhea or loss of appetite.

Pregnant women and those during menstruation should use under the guidance of a physician. Although Eclipta prostrata (旱莲草) and Imperata cylindrica rhizome (茅根) are not absolute contraindications in traditional use during pregnancy, Imperata rhizome is cold in nature and has diuretic effects. Given the unique constitution of pregnant women, excessive use may disturb fetal qi. During menstruation, if a woman is constitutionally deficient-cold, consuming cold-natured decoctions may lead to menstrual blood stasis and aggravated abdominal pain. Additionally, individuals with extreme constitutional weakness, marked by shortness of breath, fatigue upon slight exertion, and susceptibility to colds—i.e., yang qi deficiency pattern—are also unsuitable for prolonged or heavy consumption of this decoction, as it may further deplete yang qi.

Ratio of ingredients in the formula

Eclipta (Eclipta prostrata, dried): 15 g. If using fresh herb, approximately 30 g is required. Choose high-quality Eclipta with intact leaves, dark green color, and no mold.

Imperata root (dried): 20 grams. Best quality has thick rhizomes, white color, and sweet taste. Fresh product: 40 grams, wash and cut into sections before use.

Pork lean meat: 150 grams. Pork tenderloin or pork leg meat is recommended, as the flesh is tender and low in fat, resulting in a broth that is light and refreshing without being greasy after stewing.

Ginger: 3 slices. Ginger can neutralize the cold nature of Lalang Grass Rhizome (Mao Gen) and Eclipta (Han Lian Cao), while removing fishy odors and enhancing aroma, thereby increasing the warmth and mildness of the soup.

Honeyed jujube (蜜枣): 1 piece (approx. 10 g). Honeyed jujube can harmonize the medicinal flavors, increase the sweet taste of the soup, and also has certain actions of supplementing the Middle and moistening dryness.

Salt: appropriate amount (about 2 grams, adjust according to taste before removing from heat).

Clear water: 1200 ml, approximately equivalent to 5–6 bowls of water. After decoction, it yields about 3–4 bowls of soup.

Preparation Method

Step 1: Prepare the ingredients. Briefly rinse Eclipta (Eclipta prostrata) and Imperata root (Imperata cylindrica) under clean water to remove surface dust. If using fresh herbs, rinse twice more and drain thoroughly. Wash the lean pork meat and cut into thick pieces about 2–3 cm square. Place in a pot with cold water, add 1 slice of fresh ginger (Zingiber officinale), bring to a boil over high heat, skim off any foam, then remove the meat and rinse with warm water. Set aside.

Step 2: Prepare for simmering. Place a casserole or ceramic soup pot on the stove, and add in order: the blanched lean meat cubes, washed Herba Ecliptae (Eclipta prostrata), Rhizoma Imperatae (Imperata cylindrica), the remaining 2 slices of fresh ginger, and honey dates. Pour in 1200 ml of water, making sure all ingredients are fully submerged. Cover with the lid and bring to a boil over high heat.

Step 3: Simmer over low heat. Once the soup comes to a boil, reduce the heat to low, maintaining a gentle bubbling state, and continue cooking for 1.5 hours. Avoid opening the lid too frequently during this time to prevent loss of aroma. Simmer until the lean meat can be easily pierced with chopsticks and the soup becomes a clear, light brown color.

Step 4: Seasoning and Serving. Just before turning off the heat, add an appropriate amount of salt to season, stir evenly, and let it sit for 2 minutes to allow the salt to fully dissolve into the soup. Strain the decoction through a fine mesh sieve or cheesecloth to remove the herb residues and ginger slices, retaining only the clear liquid and lean meat pieces. Pour the soup into a bowl and drink while warm. The lean meat can be dipped in a small amount of soy sauce for consumption.

Drinking Tips

The best time for consumption is on an empty stomach in the morning or between 3–5 PM (the Shen period, when the Bladder Meridian is active). During this time, it helps enhance the effects of Imperatae rhizoma (cogongrass rhizome) in clearing heat and promoting urination, aiding the body in eliminating metabolic waste. Continuous consumption should not exceed 7 days; if continued use is necessary, a 2–3 day interval should be observed before resuming.

2. This decoction should be consumed warm; iced or cold consumption is not recommended. Drinking it cold not only weakens the medicinal effect but may also irritate the gastrointestinal tract, especially for individuals with pre-existing weak spleen and stomach function. If too much is prepared at one time, the remaining decoction should be stored in the refrigerator and must be fully reheated to boiling before subsequent consumption.

3. During the consumption period, attention should be paid to dietary combinations. Avoid simultaneously consuming large amounts of pungent, hot, and fire-promoting foods such as chili peppers, Sichuan pepper, lamb, and Chinese chives, as these may conflict with the decoction’s heat-clearing action. Appropriate pairing with cooling and moistening ingredients such as lotus root, winter melon, and pear can help enhance the overall effect of nourishing yin and clearing heat.
