Fresh Lotus Leaf and Winter Melon Soup: Summer Health Recipe & Benefits

Introduction to Medicinal Diet

Fresh Lotus Leaf and Wax Gourd Soup is a traditional seasonal dietary preparation originating from the Lingnan region. Its main ingredients are fresh lotus leaf (Nelumbo nucifera) and wax gourd (Benincasa hispida), supplemented with coix seed (Coix lacryma-jobi) and rice bean (Vigna umbellata), slowly simmered over low heat. This soup is popular during the hot summer months because of its refreshing sweetness and cooling effect. It may help support comfort during summer heat and occasional thirst, and it is often used as a part of a balanced dietary approach for overall wellness.

Lotus leaf is the leaf of *Nelumbo nucifera* (lotus) from the Nymphaeaceae family; when freshly picked, it has an aromatic qi and a slightly astringent taste. Winter melon is the fruit of *Benincasa hispida* (wax gourd) from the Cucurbitaceae family; it has green skin, white flesh, abundant juice, and a bland flavor. When combined, the two ingredients—one ascending and one descending, one clearing and one draining—may help support the body’s natural processes of maintaining coolness and fluid balance while also promoting digestive comfort. Fresh Lotus Leaf and Winter Melon Soup is passed down from folk dietary wisdom and has been recognized by modern nutritional science for its low-calorie, high-dietary-fiber, and vitamin-rich characteristics, making it a health-supporting soup suitable for all ages.

Efficacy of Medicinal Diet

Fresh Lotus Leaf and Winter Melon Soup may help support the body’s natural cooling mechanisms during warm weather. It may provide comfort for occasional feelings of restlessness, thirst, and excessive perspiration, and help maintain a sense of lightness and clarity. The alkaloids and flavonoids in lotus leaf (Nelumbo nucifera) may support normal vascular function and promote heat dissipation, while the high water content in winter melon (Benincasa hispida) helps replenish fluids lost through perspiration. The synergistic effect of these two ingredients may support the body’s ability to maintain a comfortable internal environment.

This decoction may also help support normal urinary function and help maintain fluid balance, assisting the body in naturally regulating water levels and eliminating occasional excess. Trigonelline in Exocarpium Benincasae (wax gourd peel) and saponins in Semen Benincasae (wax gourd seeds) may support renal circulation and urine output, thereby helping to maintain normal limb and eyelid appearance. Meanwhile, nuciferine in Folium Nelumbinis (lotus leaf) may help support healthy fat metabolism and lipid levels, providing nutritional support for individuals with weight management goals.

Antioxidation and Supporting Healthy Aging

Fresh lotus leaf (Nelumbo nucifera) is rich in polyphenolic compounds and vitamin C, natural antioxidants that help support the body’s ability to maintain cellular health by neutralizing free radicals and reducing oxidative stress. Regularly consuming Fresh Lotus Leaf and Winter Melon (Benincasa hispida) Soup may help maintain skin elasticity and radiance, support normal cellular function, and promote a healthy glow from within. The B-complex vitamins in winter melon also support metabolism and may help maintain smooth skin texture.

The Role of Traditional Chinese Medicine

According to the theory of TCM properties, flavors, and meridian tropism, lotus leaf (Nelumbo nucifera) is bitter and astringent in taste, neutral in nature, and enters the Liver (LR), Spleen (SP), and Stomach (ST) meridians. It is traditionally used to help support the body’s ability to handle warm weather, maintain fluid balance, and promote digestive comfort. The *Bencao Gangmu* (Compendium of Materia Medica) records that lotus leaf can “help engender and effuse original qi, support normal circulation, and maintain fluid balance.” Wax gourd (Benincasa hispida, also known as winter melon) is sweet and bland in taste, slightly cold in nature, and enters the Lung (LU), Large Intestine (LI), and Bladder (BL) meridians. It is traditionally valued for helping maintain normal body temperature, supporting respiratory comfort, and promoting hydration. When combined, they may help maintain balance without disrupting normal functions, supporting both the upper and lower body systems.

In summer, the prevailing warm and humid environment may affect the body’s comfort. When these factors combine, occasional sensations of chest tightness, abdominal fullness, reduced appetite, or sticky stools may occur. In the Fresh Lotus Leaf and Winter Melon Soup, lotus leaf (Nelumbinis Folium) is light and floating in nature, traditionally believed to help disperse warmth and support clear energy; winter melon (Benincasae Exocarpium) is sweet and mild, descending in action, traditionally used to help maintain fluid comfort and support normal water passage. One disperses while the other percolates, helping the body maintain comfort from both the exterior and interior, thus promoting overall well-being. The addition of coix seed (Coicis Semen) and red adzuki bean (Vignae Semen) further strengthens the effect of supporting digestive health and maintaining fluid balance, so that the body’s systems are supported without compromising natural vitality.

Suitable Population

Fresh Lotus Leaf and Winter Melon Soup is particularly suitable for individuals who work or live in high-temperature environments, such as outdoor workers, those who frequently move in and out of air-conditioned indoor spaces, and people with a constitution prone to occasional internal heat characterized by dry mouth, thirst, and restlessness. For these individuals, drinking this soup may help support fluid and electrolyte balance, promote comfort during warm weather, and help maintain the body’s normal fluid metabolism.

For individuals with weight management goals, or those seeking to support healthy lipid and blood pressure levels, as well as mild fluid considerations, Fresh Lotus Leaf and Winter Melon Soup is an ideal dietary accompaniment. The alkaloids in lotus leaves (Nelumbo nucifera) may help support normal fat metabolism, while winter melon (Benincasa hispida) is almost fat-free and rich in dietary fiber, helping to promote satiety and support normal intestinal function. Additionally, middle-aged and elderly individuals who wish to support weight control, as well as women interested in maintaining skin health, may incorporate this soup into their daily dietary regimen.

Contraindicated Populations

Individuals with a tendency toward Spleen and Stomach deficiency cold patterns should use caution when consuming Fresh Lotus Leaf and Winter Melon Soup (Nelumbo nucifera leaf and Benincasa hispida). Such individuals typically present with aversion to cold, occasional abdominal discomfort, loose stools, reduced appetite, and a pale tongue with a white slippery coating. Since winter melon is slightly cold in nature and lotus leaf is relatively cool, excessive consumption may further affect digestive comfort and may exacerbate occasional cold sensations. If consumption is necessary, it is recommended to add 3 slices of ginger (Zingiber officinale) and 5 red dates (Ziziphus jujuba) to help warm and harmonize the stomach, thereby reducing the cooling nature of the soup.

Women during menstruation should not consume large amounts of Fresh Lotus Leaf and Winter Melon Soup. Lotus leaf (Nelumbo nucifera) has an astringent property that may interfere with normal menstrual flow; the cool nature of winter melon (Benincasa hispida) may also affect uterine comfort, potentially contributing to occasional menstrual discomfort. Pregnant women should take it cautiously under the guidance of a healthcare professional, to avoid any potential effects on the fetus from the astringent action of lotus leaf or the diuretic effect of winter melon. Individuals with renal concerns accompanied by significant fluid retention, as well as those currently taking warming and tonifying herbal formulas, should also consume it with discretion under medical supervision.

Proportions of ingredients in a medicinal food formula.

The following is the standard recipe ratio for Fresh Lotus Leaf and Winter Melon Soup (calculated for 4 servings):

• Fresh lotus leaf (Nelumbinis Folium): 1 piece (approx. 30 g, select green tender leaves harvested in the early morning, free from insect damage)
• Wax gourd: 500 g (with skin, cut into 3 cm cubes)
• Job’s Tears (Coix lacryma-jobi var. ma-yuen, Yi Yi Ren): 30 g (pre-soak in clean water for 2 hours)
• Vigna angularis (Red Azuki Bean): 20 g (soak in clean water for 2 hours in advance)
• Fresh ginger (Zingiber officinale): 3 slices (about 10g, use mature ginger, do not peel)
• Honeyed Jujube (Ziziphus jujuba): 2 pieces (approx. 15 g, to enhance the sweet flavor of the soup)
• Salt: appropriate amount (approximately 3 g, used for seasoning just before removing from the heat).
• Water: 2000 ml (approximately 8 bowls of water; you may add more as needed during the decoction process).

The above ratio can be fine-tuned according to individual constitution and seasonal dryness. For those with a tendency toward damp heat, increase the Vigna umbellata (small red bean) to 30 grams. For those with occasional fatigue, add 5 pitted Ziziphus jujuba (red date) to support vitality. All ingredients should be fresh and free from spoilage to ensure the best flavor and nutritional value of the meal.

Preparation Method

Step 1: Preparation. Gently rinse fresh lotus leaf (He Ye, Nelumbinis Folium) with clean water to remove surface dust and impurities; avoid excessive scrubbing to prevent damaging the fine hairs on the leaf surface. Cut the lotus leaf into large pieces approximately 10 cm square and set aside. Scrub the skin of winter melon (Dong Gua, Benincasae Fructus) with a brush, then cut into 3 cm cubes with the skin intact. The winter melon seeds (Dong Gua Zi, Benincasae Semen) may be retained or removed—for those seeking to support urinary comfort, it is recommended to keep the seeds and cook them together.

Step 2: Soaking treatment. Rinse the coix seeds (Semen Coicis) and red adzuki beans (Semen Phaseoli) separately with clean water twice to remove dust, then soak them separately in enough clean water for more than 2 hours to allow full absorption and swelling, making them easier to cook until soft and release flavor. Wash the fresh ginger (Rhizoma Zingiberis Recens) with clean water, slice it thinly without peeling, because ginger peel (Cortex Zingiberis Rhizomatis) is traditionally used to support fluid balance, aligning with the overall wellness benefits of the soup.

Step Three: Prepare the soup base. Pour the soaked coix seed (Coicis Semen) and adzuki bean (Phaseoli Semen) together with the soaking water into a soup pot. Add 2000 ml of clean water and sliced fresh ginger (Zingiberis Rhizoma Recens). Cover with a lid and bring to a boil over high heat, then reduce to low heat and simmer for 30 minutes until the coix seed and adzuki bean are slightly cracked and the soup becomes a light beige color.

Step 4: Combine and simmer into soup. Add the prepared winter melon chunks (Benincasa hispida) and honeyed jujubes (Ziziphus jujuba) to the soup pot. Continue simmering over low heat for 20 minutes, until the winter melon becomes translucent and can be easily pierced through with chopsticks. Then place the fresh lotus leaf (Nelumbo nucifera) on the surface of the soup, cover the pot, and continue simmering over low heat for 10 minutes to allow the aromatic essence of the lotus leaf to fully infuse into the soup. Turn off the heat, remove and discard the lotus leaf, and finally season with salt to taste. Stir well and serve.

Drinking Tips

Fresh Lotus Leaf and Winter Melon Soup should be consumed warm; it is not recommended to drink it directly after refrigeration. When taken warm, the nutritional components in the soup are more easily absorbed by the body and will not cause cold stimulation to the digestive system. If a larger batch is prepared, it can be stored in the refrigerator and reheated to a warm temperature before drinking. Avoid repeated boiling, as this may destroy the active constituents in the lotus leaf.

2. The optimal consumption period for this soup is between 9:00 AM and 5:00 PM, when the body’s natural energy is abundant and metabolism is active, making the cooling and fluid-balancing effects most supportive. Avoid large amounts after dinner to prevent frequent nighttime urination from disturbing sleep quality. Consume 2 to 3 times per week; in summer, it may be increased to every other day, but it should not be overused as a daily staple.

3. Fresh Lotus Leaf and Winter Melon Soup should not be taken in large quantities simultaneously with warming tonics (such as Panax ginseng, Astragalus membranaceus, Cinnamomum cassia, etc.), to avoid the potential conflict between its cooling nature and the warming herbs, which may diminish their respective benefits. If other dietary supplements or medications are being taken, it is recommended to wait at least 1.5 hours after consuming this soup. Additionally, honeyed jujubes and table salt have already been added for seasoning, so no extra sugar, soy sauce, or other condiments are needed to preserve the natural clear sweetness and the nutritional value of this preparation.
