Eclipta and Winter Melon Blood-Cooling Soup Recipe & Benefits

Introduction to Medicinal Diet

Eclipta and Winter Melon Cooling Blood Soup (旱莲冬瓜凉血汤) is a traditional medicinal diet originating from folk medicine, with the primary function of helping the body maintain natural cooling and balance. The term “旱莲” in its name refers to the Chinese medicinal herb Eclipta prostrata (also known as Mo Han Lian or Jin Ling Cao), while “冬瓜” is the common winter melon (Benincasa hispida), a vegetable frequently used by households in summer and autumn. This soup skillfully combines the moistening and supporting properties of Eclipta with the gentle diuretic support of winter melon, complemented by a small amount of seasoning. The result is a clear broth with a refreshing taste, which can be enjoyed as a daily mealtime beverage or consumed during the transition from lingering summer heat to nascent autumn dryness, helping the body maintain internal comfort and balance.

According to the *Compendium of Materia Medica*, Eclipta (Eclipta prostrata) “supports hair and kidney health,” while Winter Melon (Benincasa hispida) “promotes healthy urinary function and thirst comfort.” The Eclipta and Winter Melon Cool-Blood Soup (旱莲冬瓜凉血汤) draws on the strengths of both ingredients, using slow simmering to fully release their properties, resulting in a soup with balanced nature that is easy to prepare at home as a wellness tonic. This soup has long been popular in the Jiangnan and Lingnan regions, especially among those who frequently stay up late, overuse their brain, or are prone to occasional internal heat. It has become a seasonal delicacy that combines traditional wisdom with culinary enjoyment.

Efficacy of Medicinal Diet

The core effects of Eclipta and Wax Gourd Blood-Cooling Decoction (旱莲冬瓜凉血汤) focus on two aspects: supporting the body’s natural cooling processes and promoting healthy fluid balance. Eclipta (旱莲草, Herba Ecliptae, Eclipta prostrata) is cool in nature, sweet and sour in flavor, and supports the Liver and Kidney meridians. It has a significant effect on supporting normal blood function and gum health, providing good support for occasional gum sensitivity, minor nosebleeds, and skin ecchymosis related to normal activity. Wax Gourd (冬瓜, Semen Benincasae, Benincasa hispida) is slightly cool in nature, sweet and bland in flavor, and can promote healthy urinary function and support the body’s natural cooling processes. It helps the body maintain balanced moisture levels, thereby supporting overall comfort during occasional restlessness or heat discomfort.

Additionally, this soup also possesses the effect of nourishing the liver and kidneys. In classical Chinese materia medica, *Eclipta prostrata* (Ecliptae Herba) has long been regarded as an excellent herb for nourishing yin and supporting kidney health, often used in combination with *Ligustrum lucidum* (Ligustri Lucidi Fructus), forming the well-known formula Er Zhi Wan (Two Ultimates Pill). The winter melon (*Benincasa hispida*), rich in vitamin C and potassium, helps maintain stable blood pressure already within normal range and supports vascular elasticity. Therefore, this Eclipta and Winter Melon Blood-Cooling Soup is not only suitable as a refreshing beverage during hot seasons but also serves as a daily nourishing option for those engaged in prolonged desk work, excessive eye strain, or presenting with occasional signs of liver-kidney yin deficiency. Overall, it embodies the dietary therapeutic characteristic of being “clearing without being cold, and nourishing without causing stagnation.”

Modern Nutritional Perspective

From the perspective of modern nutrition, Eclipta prostrata (Eclipta/False Daisy) contains various flavonoids, coumarins, and triterpenoids, exhibiting antioxidant properties, support for a healthy inflammatory response, and support for immune function. Benincasa hispida (wax gourd/winter melon) is rich in dietary fiber and water, with very low caloric content, which can promote intestinal peristalsis and help reduce lipid absorption as part of a healthy diet. The synergistic action of these two substances can support the body’s defense against oxidative stress and support healthy aging, as well as support a healthy metabolic environment, thereby providing certain benefits in supporting weight management and cardiovascular health as part of a balanced lifestyle.

The Role of Traditional Chinese Medicine

In Traditional Chinese Medicine theory, the mechanism of Han Lian Dong Gua Liang Xue Tang (Eclipta-Wax Gourd Blood-Cooling Decoction) primarily revolves around the two physiological concepts of “blood heat” and “dampness-heat.” TCM holds that blood heat can result from external factors, emotional stress, or excessive consumption of certain foods, and may be associated with occasional redness, minor bleeding tendencies, or thirst. Han Lian Cao (Eclipta prostrata, Eclipta), with sour taste and cool nature, supports the blood aspect to help maintain normal blood function and gum health, particularly beneficial for upper body comfort. Dong Gua (Benincasa hispida, Wax Gourd) is known for promoting healthy fluid circulation in the lower body, allowing the body to maintain balanced moisture levels and supporting normal urinary function.

Simultaneously, Eclipta prostrata (旱莲草) also nourishes the Liver and Kidneys, making it effective for supporting normal blood containment functions related to liver and kidney yin deficiency. The gentle nature of Wax Gourd (Benincasa hispida, 冬瓜) helps to promote fluid balance without causing discomfort, ensuring the formula as a whole supports the stomach and body fluids. The combination of these two ingredients—one supporting cooling, one supporting urination; one nourishing, one supporting—embodies the formula design principle of “supporting the upper and securing the lower, addressing both immediate and long-term balance.” This approach not only provides rapid relief for occasional heat-related discomfort but also supports the underlying constitution by nourishing the Liver and Kidneys and promoting healthy fluid transformation, reflecting the wisdom of TCM medicinal cuisine in “seeking balance as the goal.”

Suitable Population

旱莲冬瓜凉血汤 (Hanlian Donggua Liangxue Tang) is especially suitable for the following groups of people: first, those who often experience occasional dry nasal passages, gum sensitivity when brushing, or easy bruising of the skin. Such individuals typically may have a red tongue body with a thin yellow coating, tend to have occasional dry mouth and throat, and prefer cool beverages. Second, office workers and students who may experience occasional eye strain, dizziness, or ringing in the ears due to chronic sleep deprivation and excessive eye strain. Drinking this decoction can help support normal eye comfort and replenish lost bodily fluids.

The third category of suitable individuals includes those who wish to support healthy blood pressure levels already within normal range, lipid metabolism, and urinary tract function. The high-potassium, low-sodium properties of wax gourd (Benincasa hispida) help maintain stable blood pressure, while the cooling properties of Eclipta (Eclipta prostrata) can help maintain overall comfort. Additionally, adolescents experiencing occasional facial blemishes or mouth discomfort due to internal heat may, under the guidance of a licensed TCM practitioner, drink this soup in moderation to support clear skin and overall wellness.

Contraindicated Populations

Although the Eclipta and Wax Gourd Blood-Cooling Decoction (旱莲冬瓜凉血汤) is relatively neutral in nature, it is not suitable for everyone. Individuals with a tendency toward digestive coldness should use this decoction with caution. Such individuals often experience occasional cold abdominal discomfort, loose stools, and poor appetite. Consuming Eclipta (Eclipta prostrata) and Wax Gourd (Benincasa hispida), which are cool in nature, may not be ideal for those with weak digestion, potentially leading to occasional digestive upset. Pregnant women and those during their menstrual period should also exercise caution. The cooling actions of Eclipta may affect uterine comfort; it is recommended to consult a professional TCM practitioner before deciding to consume this decoction.

In addition, individuals allergic to Eclipta prostrata (false daisy) or Benincasa hispida (wax gourd) should avoid this decoction. Patients taking anticoagulant medications such as warfarin should also exercise caution, as Eclipta prostrata may have mild blood-thinning properties that could interact; therefore, prolonged or high-dose consumption is not advised without professional guidance. This decoction is also unsuitable for individuals with a Yang deficiency pattern—characterized by extreme weakness, aversion to cold, and cold extremities—as it may further challenge the body’s energy balance and consequently hinder overall health maintenance.

Ratio of Ingredients in the Formula

To prepare the Eclipta and Wax Gourd Blood-Cooling Soup (旱莲冬瓜凉血汤), the required ingredients include: 15g of dry Eclipta (Herba Ecliptae; if using fresh product, about 30g), 300g of fresh wax gourd (winter melon, preferably with peel on, as wax gourd peel has a stronger effect of promoting urination and reducing edema), 2 slices of fresh ginger (about 3g), 3 red dates (Chinese jujube, about 9g, broken and pitted), an appropriate amount of salt (about 1-2g), and optionally a small amount of rock sugar or honey to adjust the taste. This ratio is the daily dosage for one adult and can be adjusted proportionally based on the number of people.

When selecting materials, **Eclipta prostrata** (旱莲草, Herba Ecliptae) is considered superior when it is dark green in color, with abundant leaves and no impurities; it can be purchased from reputable Chinese pharmacies or trusted online herb suppliers. **Wax gourd** (冬瓜, Benincasa hispida) should be chosen with a hard, blemish-free skin, thick firm flesh, and white interior. **Ginger** (生姜, Zingiber officinale) should be **old ginger** (老姜) for its stronger effect in supporting the body’s natural warming processes. **Red dates** (红枣, Ziziphus jujuba) are best when the flesh is plump and the skin is bright red in color. For enhanced cooling support, **fresh cogongrass rhizome** (鲜白茅根, Imperata cylindrica, 10 g) may be added and decocted together, but first-time consumers are advised to start with the basic formula and adjust as needed once they have become accustomed to it.

Preparation method

First, quickly rinse the dried Eclipta (Eclipta prostrata) under running water to remove surface dust, then place it in a bowl and soak in room-temperature drinking water for about 15 minutes to facilitate the extraction of its beneficial properties. Rinse the winter melon (Benincasa hispida) under running water, and cut it with the skin intact into 2–3 cm square pieces—the winter melon skin is rich in various active compounds, so retaining it yields better results. Smash the fresh ginger (Zingiber officinale) and set aside. Wash the red dates (Ziziphus jujuba), then cut them in half lengthwise and remove the pits.

Step 2: Take a clay pot or stainless steel pot, pour the soaked Eclipta prostrata (Common Eclipta) together with the soaking water into the pot, then add enough clean water to reach a total volume of about 1500 ml. Bring to a boil over high heat, then reduce to low heat and maintain a gentle simmer for 20 minutes. When the liquid gradually turns a light brown color and the herbal aroma is released, remove the Eclipta prostrata residue using a fine mesh strainer, retaining only the clear decoction.

Step 3: Add the cut wax gourd chunks (Donggua), fresh ginger slices (Shengjiang), and red dates (Hongzao) to the soup. Return to a boil over high heat, then reduce to medium-low heat and continue simmering for 25–30 minutes until the wax gourd is fully tender and translucent. Just before turning off the heat, season with table salt (Shiyan). If a sweet taste is desired, add a small amount of rock sugar (Bingtang) and stir to dissolve. Allow the soup to cool slightly before ladling into bowls for drinking. The wax gourd chunks can be chewed directly, and the jujube pulp will be soft and sticky—there is no need to discard them.

Drinking Tips

1. The best time for consumption is between 9–11 am or 3–5 pm. These two periods correspond to the peak times of the Spleen Meridian (SP) and the Bladder Meridian (BL), respectively, which facilitates the absorption and metabolism of the active ingredients in the decoction. It is not recommended to drink it on an empty stomach, to avoid potential digestive discomfort. Also, avoid drinking within one hour before bedtime to prevent diuretic effects from affecting sleep quality.

2. Eclipta and Winter Melon Blood-Cooling Soup should be consumed while warm and not directly after refrigeration or chilling. Although the soup is cool in nature, excessively low temperatures can challenge digestive balance, reducing the overall efficacy of the medicinal diet. If a larger quantity is prepared, it may be stored sealed in the refrigerator for no more than 24 hours. When consuming again, reheat to a slightly warm temperature, and do not reheat more than twice.

3. This soup is intended for daily dietary wellness and health maintenance. It is recommended not to consume it continuously for more than 7 days, then take a break of 2–3 days before deciding whether to continue based on your body’s response. If discomfort such as diarrhea, abdominal pain, or marked aversion to cold occurs during consumption, discontinue immediately and observe. To support effectiveness, reduce the intake of spicy, greasy, and grilled foods during the consumption period, so as not to counteract the soup’s cooling and supporting effects.
