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 medicinal diet 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 highly popular among the people during the hot summer months because of its refreshing sweetness and cooling effect. It not only relieves summer-heat vexation and thirst but also transforms dampness and turbidity, making it an excellent choice for summer health preservation and dietary therapy.

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—enable the entire medicinal food formula to clear heat and drain dampness while simultaneously protecting the qi of the spleen and stomach. Fresh Lotus Leaf and Winter Melon Soup is passed down from folk dietary therapy wisdom and has been verified by modern nutritional science. Its low-calorie, high-dietary-fiber, and vitamin-rich characteristics make it a health-promoting soup suitable for all ages.

Efficacy of Medicinal Diet

The primary efficacy of Fresh Lotus Leaf and Winter Melon Soup lies in clearing heat and resolving summerheat. It provides good relief from symptoms such as irritability, thirst, excessive sweating, dizziness, and heaviness in the head caused by high summer temperatures. The alkaloids and flavonoids in lotus leaf (Nelumbo nucifera) can dilate blood vessels and promote heat dissipation, while the over 96% water content in winter melon (Benincasa hispida) quickly replenishes fluids lost through perspiration. The synergistic effect of these two ingredients resolves summerheat from both the interior and exterior.

This decoction also has a significant effect of promoting urination and reducing edema, helping the body eliminate excess water and metabolic waste. Trigonelline in Exocarpium Benincasae (wax gourd peel) and saponins in Semen Benincasae (wax gourd seeds) can increase renal blood flow and urine output, thereby alleviating limb edema and eyelid swelling. Meanwhile, nuciferine in Folium Nelumbinis (lotus leaf) promotes fat metabolism and lowers blood lipid levels, providing supportive regulation for individuals with hyperlipidemia and simple obesity.

Antioxidation and Delaying Aging

Fresh lotus leaf (Nelumbo nucifera) is rich in polyphenolic compounds and vitamin C, natural antioxidants that effectively scavenge free radicals and reduce oxidative stress damage in the body. Regularly consuming Fresh Lotus Leaf and Winter Melon (Benincasa hispida) Soup helps maintain skin elasticity and radiance, slows the aging process of cells, and promotes a healthy glow from within. The B-complex vitamins in winter melon also support metabolism and improve rough 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 clears summerheat, drains dampness, ascends and effuses clear yang, and cools the blood to stop bleeding. The *Bencao Gangmu* (Compendium of Materia Medica) records that lotus leaf can “engender and effuse original qi, dissipate static blood, and reduce edema.” 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 excels at clearing heat and resolving toxin, disinhibiting water and transforming phlegm, and relieving vexation and quenching thirst. When combined, they clear heat without damaging yang, drain dampness without impairing yin, mutually support ascending and descending, and treat both the exterior and interior simultaneously.

In summer, the prevailing summer-heat qi often combines with dampness to invade the body. When dampness and heat steam together, symptoms such as chest oppression, abdominal distension, poor appetite, and sticky, unsmooth stools may occur. In the Fresh Lotus Leaf and Winter Melon Soup, lotus leaf (Nelumbinis Folium) is light and floating in nature, able to disperse summer-heat and upbear and effuse clear yang; winter melon (Benincasae Exocarpium) is sweet and mild, descending in action, able to percolate and disinhibit dampness turbidity and regulate the water passages. One disperses while the other percolates, allowing the dampness-heat pathogen to be resolved from both the exterior and interior, thus smoothing the qi mechanism of the Triple Burner. The addition of coix seed (Coicis Semen) and red adzuki bean (Vignae Semen) further strengthens the effect of fortifying the spleen and disinhibiting dampness, so that dampness is eliminated while the spleen and stomach are strengthened, and right qi is restored without harming the body’s healthy qi.

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 “*shanghuo*” (excessive internal heat) characterized by dry mouth, thirst, and irritability. For these individuals, drinking this soup can help replenish fluids and electrolytes, alleviate discomfort caused by summer heat, and regulate the body’s fluid metabolism balance.

For individuals with simple obesity, hyperlipidemia, hypertension, and mild edema, Fresh Lotus Leaf and Winter Melon Soup is also an ideal adjunctive dietary therapy. The alkaloids in lotus leaves (Nelumbo nucifera) can inhibit fat absorption and promote fat breakdown, while winter melon (Benincasa hispida) is almost fat-free and rich in dietary fiber, helping to increase satiety and promote intestinal peristalsis. Additionally, middle-aged and elderly individuals who need to control their weight, as well as women who wish to improve their skin condition, can also incorporate this soup into their daily dietary regimen.

Contraindicated Populations

Individuals with Spleen and Stomach Deficiency Cold pattern 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, cold pain in the abdomen, loose stools, poor 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 damage Spleen Yang and exacerbate Cold Dampness, leading to worsened diarrhea or epigastric discomfort. If consumption is necessary, it is recommended to add 3 slices of ginger (Zingiber officinale) and 5 red dates (Ziziphus jujuba) to warm the Middle Burner and harmonize the Stomach, thereby reducing the cold 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 the normal discharge of menstrual blood; the cold nature of winter melon (Benincasa hispida) may also aggravate uterine cold (Bing Han), triggering or worsening dysmenorrhea. Pregnant women should take it cautiously under the guidance of a professional TCM practitioner, to avoid potential adverse effects on the fetus from the blood-activating action of lotus leaf or the diuretic effect of winter melon. Individuals with renal insufficiency accompanied by severe edema, as well as those currently taking warming and tonifying Chinese 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 predominant damp-heat, increase the Vigna umbellata (small red bean) to 30 grams. For those with shortness of breath and fatigue, add 5 pitted Ziziphus jujuba (red date) to supplement qi and blood. All ingredients should be fresh and free from spoilage to ensure the best efficacy and taste of the medicinal 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 enhance the diuretic effect, 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) has the effect of promoting urination to reduce edema, which aligns with the overall efficacy 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 medicinal components in the soup are more easily absorbed by the body and will not cause cold stimulation to the spleen and stomach. 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 yang qi is abundant and metabolism is active, making the effects of clearing heat and draining dampness most pronounced. Avoid large amounts after dinner to prevent frequent nocturia 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 tonic medicinals (such as Panax ginseng, Astragalus membranaceus, Cinnamomum cassia, etc.), to avoid the conflict between its cooling nature and the warming tonics, which may counteract each other’s effects. If other Chinese or Western 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 therapeutic efficacy of this medicinal food.
