Winter Melon and Coix Seed Soup: Recipe, Benefits, and Traditional Wellness Guide

Introduction to Nourishing Soup

Winter Melon and Coix Seed Pork Bone Soup is a traditional nourishing soup originating from the Lingnan region of China. It is appreciated for helping maintain a feeling of lightness and supporting healthy fluid balance, making it especially suitable for those living in damp-heat environments, such as in Guangdong, Guangxi, Hainan, and similar areas. This soup is made primarily with winter melon (Benincasa hispida), coix seed (Coix lacryma-jobi, also known as Yi Yi Ren), and pork spine bones, supplemented with a small amount of fresh ginger (Zingiber officinale) and dried tangerine peel (Citri Reticulatae Pericarpium). After slow simmering over low heat, the soup becomes clear in color, richly aromatic, and has a smooth, refreshing texture. Whether enjoyed as a daily side soup or consumed during hot, humid seasons or when seeking to support internal balance, it is a suitable choice.

Winter Melon, Coix Seed, and Pork Spine Soup is based on the traditional concept of “medicine and food sharing the same origin.” Winter melon (Benincasa hispida) has a cool nature with a sweet and bland taste; coix seed (Coix lacryma-jobi var. ma-yuen) is slightly cold in nature and also sweet and bland. Together, they help support healthy urinary function and maintain water balance, assisting the body in staying comfortable. Pork spine bones are rich in collagen and calcium, which help nourish bones and joints while adding a richer flavor to the soup. This soup is simple to prepare, with easily accessible ingredients, making it a classic among family health soups. It is especially suitable for modern individuals who wish to support internal balance despite irregular dietary habits and a hectic lifestyle.

Benefits of Health-Nourishing Soup

Winter Melon, Coix Seed, and Pork Spine Soup (Donggua Yimi Jigu Tang) primarily helps maintain a cool and balanced fluid state in the body, while supporting digestive system and Kidney health. Benincasa hispida (wax gourd, Donggua) possesses strong diuretic properties that help maintain normal fluid levels, assisting the body in eliminating excess water and metabolic waste. Coix lacryma-jobi var. ma-yuen (Job’s tears, Yiren) helps helps with occasional dampness in the Spleen and stomach region, supporting digestive comfort and energy levels. Pork spine (suillae vertebrae) helps nourish the Kidneys and lower back, replenishing Zheng Qi (vital energy) that may be depleted by damp-heat conditions, thereby supporting the body without compromising health.

From a nutritional perspective, this soup is rich in a variety of vitamins, minerals, and high-quality protein. Winter melon (Benincasa hispida) is high in vitamin C and potassium, which supports cardiovascular health and helps maintain normal blood pressure. Coix seed (Coix lacryma-jobi var. ma-yuen / Job’s tears) contains coixenolide, protein, and dietary fiber, and provides antioxidant benefits, supports normal blood sugar levels, and helps maintain a healthy immune response. When consumed regularly and in moderation over time, it supports metabolic health and may be used as an adjunct to promote skin comfort.

Benincasa hispida (Winter Melon) supports a balanced internal environment and promotes normal urinary function.

In *Compendium of Materia Medica (Bencao Gangmu)*, winter melon (*Benincasa hispida*) is recorded as “traditionally used to support abdominal comfort and fluid balance, and help with occasional thirst.” Its nature of supporting a balanced internal environment and promoting healthy fluid metabolism is particularly suitable for summer. The peel and flesh of winter melon are more pronounced in supporting fluid balance; therefore, when making nourishing soups, it is usually recommended to keep the outer peel to enhance the effect of supporting fluid balance.

Coix lacryma-jobi (Job’s tears) supports Spleen function and helps maintain normal fluid metabolism.

Coix seed (Semen Coicis) is a traditional ingredient used to help maintain internal comfort and balanced moisture. When used raw, it tends to support the body’s cooling functions and healthy water metabolism; after dry-frying, it focuses on supporting digestive health and regular bowel movements. In Winter Melon and Coix Seed Pork Bone Soup, Coix seed works synergistically with winter melon—one supports cooling, the other promotes drainage—to effectively help the body restore the Spleen and stomach’s normal transportation and transformation functions.

The Role of Traditional Chinese Medicine

In traditional Chinese medicine theory, Winter Melon, Coix Seed, and Pork Spine Bone Soup primarily acts on the Spleen, Stomach, and Kidney organs. The Spleen governs the transformation and transportation of fluids; the Stomach governs receiving and ripening; the Kidney governs water metabolism. When improper diet or external contraction of Damp-Heat leads to Spleen failing to transport and transform, Stomach failing to harmonize and descend, and Kidney failing to transform Qi, signs of imbalance such as edema, difficult urination, loose stools, and heavy sensation in limbs may occur. This soup supports normal urination and fluid balance through Winter Melon, supports digestion and joint comfort through Coix Seed, and supports Kidney nourishment and vitality through Pork Spine Bone, helping to maintain healthy fluid metabolism.

From the perspective of nature, flavor, and meridian affinity, Donggua (Benincasa hispida, wax gourd) is sweet, bland, and slightly cold. It enters the Lung, Large Intestine, and Bladder Meridians, and helps maintain a balanced internal environment in the Lungs while supporting normal urinary function. Yiyiren (Coix lacryma-jobi var. ma-yuen, coix seed) is also sweet, bland, and slightly cold, entering the Spleen, Stomach, and Lung Meridians. It supports healthy Spleen function and dampness regulation, and helps maintain comfortable joint movement. Zhujigu (Sus scrofa domestica, pig spine bone) is sweet, salty, and neutral in nature. It enters the Kidney and Spleen Meridians, and helps nourish the Kidneys while supporting strong bones and tendons. Combined, these three ingredients are cooling without being harsh, nourishing without causing stagnation, and simultaneously support the body’s resistance and balance. This combination is especially suitable for individuals who experience a tendency toward dampness accumulation along with underlying Spleen and Kidney weakness. Adding Shengjiang (Zingiber officinale, fresh ginger) not only removes any fishy taste and enhances flavor, but also warms the Spleen and stomach, moderating the cool nature of Donggua and Yiyiren. This makes the overall soup nature more balanced and gentle.

Suitable Individuals

Winter Melon, Coix Seed, and Pork Spine Soup is especially suitable for the following individuals: First, those who feel a sense of heaviness in the body, have an oily complexion, are prone to occasional blemishes, experience dry mouth and bitter taste, notice sticky stools, or produce dark urine—essentially anyone looking to maintain a fresh, balanced internal environment. Second, individuals with a tendency toward occasional swelling, including those with idiopathic puffiness, mild fluid retention, or women who experience slight swelling before or after their menstrual period. Third, people who wish to support normal uric acid levels, as winter melon and coix seed help promote the body’s healthy elimination of uric acid. Fourth, during the summer months, those who feel sluggish digestion or low energy—this soup can help clear heat and support digestive comfort, thereby assisting in maintaining appetite and overall vitality.

Additionally, urban office workers who sit for long periods and lack exercise, as well as those who consume excessive greasy or sweet foods, or drink and smoke heavily, are prone to accumulating dampness in the body. Moderate consumption of Winter Melon and Coix Seed Spine Soup helps support the body’s metabolic environment and helps with occasional the metabolic load on the Liver and Kidneys. For the elderly and children, as long as their Spleen and stomach function is normal, they may also consume this soup in moderation during hot and humid summer months, but attention should be paid to portion sizes and frequency.

Not Suitable for:

Wax Gourd and Coix Seed Pork Spine Soup (Benincasa hispida [Donggua] and Coix lacryma‑jobi var. ma‑yuen [Yiyiren] with pork spine bones) is a mild nourishing soup, yet it is not suitable for everyone. Individuals with a tendency toward Spleen and Stomach Deficiency Cold should exercise caution or avoid consumption. This constitution often presents with cold discomfort in the stomach, a preference for warmth and pressure, loose stools, and aversion to cold. Drinking this soup may aggravate Spleen and Stomach disharmony. Coix seed (Yiyiren) traditionally has a slippery nature and is not recommended for pregnant women, especially during the first trimester, as it may stimulate uterine smooth muscle contractions, potentially affecting pregnancy stability. Wax gourd (Donggua) has a relatively strong diuretic effect; therefore, those with frequent urination or increased nocturia should reduce intake to avoid exacerbating these conditions.

Additionally, individuals with a weak constitution or Qi and Blood Deficiency should also avoid prolonged or excessive consumption, as the diuretic effect of wax gourd (Donggua) and Coix seed (Yiyiren) may deplete some water-soluble vitamins and minerals, and excessive diuresis may impair body fluid balance. During the use of Qi-tonifying herbs such as Panax ginseng (Renshen) and Astragalus membranaceus (Huangqi), it is advisable to reduce or discontinue intake of this soup, as Coix seed is traditionally considered incompatible with these ingredients. Those allergic to wax gourd, Coix seed, or pork bones should avoid consuming it. Individuals in the post-surgery recovery period or those taking specific medications (e.g., diuretics, blood sugar-lowering drugs) should consume it cautiously under the guidance of a doctor or pharmacist.

Ingredient Formula Ratio

Standard ingredients for a four-serving winter melon and coix seed pork backbone soup are as follows: 500 grams of winter melon with skin (preferably mature winter melon with dark green skin and thick flesh); 60 grams of raw Semen Coicis (Coix seed, also known as Job’s tears, ideally plump, white, and clean); 400 grams of pork backbone (choose fresh pieces with a bit of meat and no off-odor); 15 grams of fresh ginger (about 5 slices, to remove fishy odors and warm the stomach); 3 grams of dried tangerine peel (about one small piece, to support qi flow and transform dampness); and salt to taste (about 3 grams, for final seasoning). For a richer flavor, you may add 2 candied dates or 3 dried figs to enhance sweetness.

The proportions of the above ingredients can be adjusted according to individual constitution and seasonal changes. For individuals with a tendency toward internal damp-heat, the amount of Semen Coicis (Coix lacryma-jobi, Yiyiren) can be increased to 80 grams, and Benincasa hispida (Donggua, winter melon) to 600 grams. For those with weaker digestive function, raw Semen Coicis can be replaced with dry-fried Semen Coicis, and the amount of winter melon reduced to 400 grams. For individuals who may benefit from supporting Kidney health, 10 grams of Cortex Eucommiae (Eucommia ulmoides, Duzhong) or 15 grams of Fructus Lycii (Lycium barbarum, Gouqi, goji berries) can be added during simmering. Pork backbone can also be substituted with lean pork or pork ribs, but pork backbone is more conducive to supporting Kidney nourishment and maintaining strong bones and muscles. Semen Coicis should be soaked in water for at least 2 hours in advance to shorten cooking time and help release beneficial components.

Cooking Method

Step 1: Preparation. Cut the pork spine into 4-5 cm sections and soak in clean water for 30 minutes to remove blood. Rinse Coix lacryma-jobi (Yiyiren, Job’s tears) thoroughly, then soak for 2 hours. Wash the wax gourd (Benincasa hispida, Donggua) with the skin on, remove the pulp and seeds, and cut into 3 cm thick chunks. Wash fresh ginger (Zingiber officinale, Shengjiang) and slice. Soak dried tangerine peel (Citri Reticulatae Pericarpium, Chenpi) in warm water until soft, then scrape off the inner pith.

Step 2: Blanching. Place the soaked pork spine bones into a pot of cold water, then add 2 slices of ginger and a small amount of cooking wine. Bring to a boil over high heat and continue boiling for 3–5 minutes. Remove the bones, and rinse off any foam with warm water. This step effectively removes any unpleasant odor and impurities from the pork bones, helping to keep the broth clear and free of cloudiness.

Step 3: Simmer the soup. Place the blanched pork spine bones, soaked Coix seed (Semen Coicis), wax gourd (Benincasa hispida) chunks, fresh ginger slices (Rhizoma Zingiberis Recens), and tangerine peel (Pericarpium Citri Reticulatae) together in a clay pot or soup pot. Add enough water (about 2500 ml) to cover the ingredients by about 5 cm. Bring to a boil over high heat, skim off any foam, then reduce to low heat and simmer for 1.5–2 hours, until the soup turns milky white, the meat separates from the bones, and the Coix seeds have bloomed.

Step 4: Seasoning and finishing. Add an appropriate amount of salt for seasoning 10 minutes before turning off the heat. Note that salt should not be added too early, as it may affect the freshness of the soup and the extraction of nutrients. After cooking, remove the tangerine peel and ginger slices, ladle the soup into bowls, and sprinkle with a little chopped scallion or cilantro to enhance the aroma. If a richer flavor is desired, wrap winter melon peel (Benincasae Exocarpium) in a gauze bag and cook it together with the soup; remove and discard the bag once the soup is done.

Usage Instructions

First, Winter Melon and Coix Seed Pork Spine Soup should be consumed while still warm. In summer, it may be allowed to cool to a warm temperature, but should not be ice-cold, as this may be too cooling for the stomach and does not support comfortable digestion. It is recommended to drink 2–3 times per week, for no more than two consecutive weeks. For long-term health maintenance, pause for one week before resuming. Each serving of 200–300 ml is appropriate; avoid excessive consumption.

Secondly, the best times for consumption are between 9–11 AM (when the Spleen Meridian (SP) is at its peak) and 3–5 PM (when the Bladder Meridian (BL) is at its peak). During these periods, the body’s fluid metabolism is most active, and drinking this soup can better support fluid balance. It is recommended to avoid large amounts after 8 PM to helps maintain frequent nighttime urination that may affect sleep quality.

Third, while consuming Winter Melon, Coix Seed, and Spine Bone Soup (Donggua Yimi Jigu Tang), attention should be paid to dietary combinations. Avoid simultaneously ingesting raw, cold, or cooling foods, as well as greasy, heavily flavored, or spicy and stimulating items, so as not to affect the transportation and transformation functions of the Spleen and Stomach. It is appropriate to pair with ingredients that support the Spleen and supplement Qi, such as Dioscorea opposita (Shanyao), Lablab purpureus (Baibiandou), and Wolfiporia extensa (Fuling), to enhance the effect of supporting proper dampness resolution. Pregnant women, individuals during menstruation, and those with a pattern of Spleen and Stomach Deficiency Cold should consume under professional guidance and adjust ingredient proportions—for example, replace raw Coix Seed (Semen Coicis) with stir-fried Coix Seed (Semen Coicis preparatum) and add warming ingredients such as Fructus Jujubae (Hongzao) to moderate the cold nature.
