Chinese Yam, Longan & Softshell Turtle Soup: TCM Recipe & Benefits

Introduction to Medicinal Diet

Soup of Chinese Yam (Dioscorea opposita), Longan (Dimocarpus longan Lour.), and Softshell Turtle (Pelodiscus sinensis) is a classic Traditional Chinese Medicinal (TCM) functional dish with both nourishing and regulating properties. It has a long history and holds an important place in the food-cure culture of the Lingnan and Jiangnan regions. “Huai Shan” refers to Chinese yam (Dioscorea opposita), with the variety produced in Huaiqing Prefecture, Henan being considered the best. Its flavor is sweet and its nature is neutral; it enters the Spleen (SP), Lung (LU), and Kidney (KI) channels. “Gui Yuan,” also known as Longan aril (Dimocarpus longan Lour.), is sweet in taste, warm and moist in nature, and excels in tonifying the Heart (HT) and Spleen (SP), nourishing blood, and calming the spirit. Softshell turtle (Pelodiscus sinensis)—also known as “bie” or “tuan yu”—has both meat and carapace (Plastrum Testudinis) used medicinally. Its nature is neutral, flavor sweet, and it acts to nourish yin, cool blood, supplement deficiency, and harmonize the Middle Burner. When these three ingredients are combined into a soup, the meat and plant components complement each other: it tonifies without causing dryness and nourishes without causing greasiness. It is an excellent recipe for autumn–winter supplementation and for recovery after illness.

This soup was similarly documented in the Qing Dynasty text *Suí Xī Jū Yǐn Shí Pǔ* (Recipes for Sui Xi Residence) and has long been used in folk medicine as a restorative dietary remedy for individuals suffering from consumptive disease with emaciation or chronic illness with general debility. The soup presents a clear, slightly milky broth with a delicate, savory flavor. The soft, starchy texture of Chinese yam (Dioscorea opposita), the natural sweetness of longan (Dimocarpus longan), and the tender, smooth quality of softshell turtle (Pelodiscus sinensis) blend harmoniously, making it not only a delicious dish but also a gentle, nourishing tonic formula. Modern nutritional science also confirms that softshell turtle is rich in high-quality protein, collagen, and various trace elements; Chinese yam contains abundant mucopolysaccharides and amylase; and longan provides ample glucose and iron. The combination of these three ingredients works synergistically for optimal benefit.

Historical origins and cultural background

As early as the Ming dynasty *Bencao Gangmu* (Compendium of Materia Medica), Li Shizhen recorded that softshell turtle (Pelodiscus sinensis) can “tonify fatigue and injury, strengthen yang qi, and greatly supplement insufficiency of yin.” The use of Chinese yam (Dioscorea opposita) and longan (Dimocarpus longan) in TCM diet therapy can be traced back even further to the *Shennong Bencao Jing* (Divine Farmer’s Materia Medica). Combining these three ingredients into a soup represents the accumulated wisdom of successive generations of medical practitioners and folk dietary nourishment. This is especially true in the southeastern coastal regions of China, where this soup is often chosen as the first choice for restorative tonification during seasonal transitions or when family members are weak.

Efficacy of Medicinal Diet

The core efficacy of Chinese Yam (Dioscorea opposita), Longan (Arillus Longan), and Soft-Shelled Turtle (Pelodiscus sinensis) soup lies in supplementing qi and nourishing yin, enriching blood and calming the spirit, and fortifying the spleen and moistening the lung. Soft-shelled turtle excels at nourishing yin and subduing yang, making it highly beneficial for conditions such as yin deficiency with effulgent fire, tidal fever and night sweats, and heat sensation in the palms and soles. Chinese Yam (Dioscorea opposita) supplements qi and nourishes yin, fortifies the spleen, and supplements the lung and kidney; it can ameliorate problems like spleen and stomach vacuity with poor appetite and fatigue, and lung vacuity cough and dyspnea. Longan (Arillus Longan) directly enters the heart and spleen channels, where it supplements and boosts the heart and spleen, nourishes blood and calms the spirit; it is particularly beneficial for palpitations, insomnia, forgetfulness, and fearful throbbing due to excessive worry or heart blood insufficiency. The three ingredients work synergistically to supplement both qi and blood, and regulate yin and yang simultaneously.

From a modern nutritional perspective, this soup is rich in collagen and a variety of amino acids, which can promote tissue repair, enhance skin elasticity, and have anti-aging effects. The amylase and dietary fiber in Chinese yam (Dioscorea opposita) aid digestion and absorption, improving gastrointestinal function. The iron and B vitamins in longan (Dimocarpus longan) support hemoglobin synthesis and help prevent iron-deficiency anemia. Therefore, regular consumption of this soup not only improves overall constitution but also promotes a rosy complexion, boosts vitality, and provides beauty-enhancing benefits.

Functions of Traditional Chinese Medicine

In TCM theory, the Soup of Chinese Yam, Longan, and Soft-shelled Turtle (Pelodiscus sinensis) is a medicinal diet formula that equally emphasizes nourishing Yin and supplementing Qi. Soft-shelled turtle has a sweet flavor and neutral nature, entering the Liver and Kidney channels. It excels at nourishing Yin and subduing Yang, as well as softening hardness and dissipating masses. It is particularly suitable for patterns such as internal stirring due to deficiency wind and bone steaming consumptive fever caused by Liver and Kidney Yin deficiency. Its carapace, known as Turtle Carapace (Plastrum Testudinis), is a key herb for nourishing Yin and clearing heat. During the decoction process, the gelatin and active constituents are fully extracted, enhancing the nourishing efficacy of the soup.

Huai Shan (Chinese yam, *Dioscorea opposita*), with its white color entering the Lung, sweet flavor entering the Spleen, and moist quality entering the Kidney, is an excellent herb that supplements all three burners (Triple Burner tonification). In the formula, it assists the softshell turtle (Carapax Trionycis) in nourishing yin while simultaneously protecting Spleen and Stomach transportation and transformation, ensuring supplementation without stagnation. Longan (Arillus Longan, *Dimocarpus longan*), sweet and warm with a moist nature, specifically tonifies Heart and Spleen blood. Combined with softshell turtle and Chinese yam, it harmonizes the Heart and Kidney, calms the spirit, and settles the mind. The combination of these three ingredients allows yin and blood to become fully replenished, deficient fire to descend naturally, Spleen and Stomach transport and transformation to be strengthened, and the Heart spirit to be nourished. This is particularly skillful at harmonizing the complex constitutional patterns commonly seen in modern individuals, such as “upper heat and lower cold” and “deficiency with inability to tolerate tonification.”

Essentials of Formula Analysis and Compatibility

The brilliance of this decoction’s formulation lies in using softshell turtle (Pelodiscus sinensis) as the sovereign to nourish yin and subdue yang; Chinese yam (Dioscoreae Rhizoma) as the minister to supplement qi and secure the middle; longan (Longan Arillus) as the assistant to nourish blood and calm the spirit; and is often further supplemented with fresh ginger (Zingiberis Rhizoma Recens) and Chinese dates (Jujubae Fructus) as the envoy to harmonize the medicinal properties, remove fishy smell, and enhance aroma. The entire formula combines activity and stillness, integrates supplementation with movement, nourishes without greasiness, and can be regarded as a model of balanced and gentle nourishment.

Indications

Chinese Yam, Longan, and Softshell Turtle Soup is suitable for individuals with Yin deficiency constitution and Qi and blood dual deficiency. Common manifestations include emaciation, dry skin, dry mouth and throat, heat in the palms and soles, irritability and insomnia, night sweats and seminal emissions, and scanty, pale menstruation. This soup is an excellent dietary nourishment choice for urban white-collar workers who suffer from long-term sleep deprivation, overuse of the brain, and spirit depletion due to excessive mental strain, as well as for those recovering from a serious illness, postoperative recovery, or postpartum blood deficiency.

In addition, due to the gradual depletion of Kidney Yin (肾阴), middle-aged and elderly individuals often experience symptoms such as soreness and weakness of the lower back and knees (腰膝酸软), tinnitus and forgetfulness (耳鸣健忘), and frequent nocturia (夜尿频多). Regular consumption of this soup can help delay aging and strengthen sinews and bones (强健筋骨). For adolescents burdened with heavy academic workloads, who may present with poor concentration, memory decline (记忆力减退), and deficient fire flaring upward (虚火上升), moderate intake can also be beneficial in nourishing the heart and calming the spirit (养心安神), as well as benefiting intelligence and the brain (益智健脑). For women experiencing menopausal syndrome (更年期综合征) with manifestations such as tidal fever and sweating (潮热汗出), vexation and irritability (心烦易怒), and insomnia with excessive dreaming (失眠多梦), consuming this soup offers a good regulating effect.

Contraindicated Populations

Although the Huai Shan (Chinese Yam, Rhizoma Dioscoreae) and Gui Yuan (Longan, Arillus Longan) Softshell Turtle Soup offers numerous benefits, it is not suitable for everyone. It should be used with caution in individuals with Spleen and Stomach Yang Deficiency (Spleen-Stomach Deficiency Cold) or Dampness Obstructing the Middle Jiao, presenting with symptoms such as epigastric and abdominal distension and fullness, loose stools, and a white, greasy tongue coating. In such cases, consumption may promote Dampness and generate Phlegm, thereby increasing the burden on the Spleen and Stomach. Those with unresolved Exterior Excess Patterns, such as Wind-Cold Common Cold presenting with fever, aversion to cold, and productive cough with copious sputum, should avoid tonifying formulas to prevent “closing the door and trapping the bandit,” thereby making it difficult for pathogenic factors to be expelled.

Soft-shelled turtle contains high levels of purines; therefore, patients in the acute phase of gout or with hyperuricemia should avoid consumption. Longan has a relatively high sugar content, so individuals with diabetes mellitus must strictly control their intake or consume it only under the guidance of a physician. Pregnant women should also exercise caution, as soft-shelled turtle possesses the effect of unblocking collaterals and dispersing stasis; excessive consumption during early pregnancy may pose a risk of disturbing the fetus. Unless instructed by a physician, random consumption is not advised. Additionally, individuals who are allergic to soft-shelled turtle or longan should naturally avoid eating them.

Ingredient Formula Ratio

Classic Formula for Chinese Yam and Longan Turtle Soup (Huai Shan Gui Yuan Jia Yu Tang): 1 live softshell turtle (approx. 500 g; preferably female with thick calipash), 200 g fresh Chinese yam (Dioscorea opposita; or 80 g dried yam slices), 30 g dried longan (Dimocarpus longan; about 20 fruits), 5 slices fresh ginger (Zingiber officinale; approx. 10 g), 8 red dates (Ziziphus jujuba; approx. 15 g), 10 g goji berries (Lycium barbarum), 20 ml yellow rice wine (Shaoxing wine), salt to taste (approx. 3 g, added at the end), 2500 ml clear water.

This is a quantity for 3-4 servings. For patients who are just recovering from a serious illness or are extremely debilitated, the amount of softshell turtle (Pelodiscus sinensis) can be increased to 750 g as appropriate, and add 15 g of *Astragalus membranaceus* (Huang Qi, Milkvetch Root) to strengthen the Qi-supplementing effect. For those with marked Yin deficiency with effulgent fire, add 10 g of *Ophiopogon japonicus* (Mai Dong, Dwarf Lilyturf Root) and 10 g of *Polygonatum odoratum* (Yu Zhu, Fragrant Solomon’s Seal Rhizome) to enhance the Yin-nourishing action. All medicinal materials and food ingredients can be purchased at reputable Chinese herbal medicine stores or fresh markets, with geo-authentic herbs and fresh live softshell turtle being preferred.

Preparation Method

**Step 1: Preparation.** Kill the softshell turtle (Pelodiscus sinensis), remove the internal organs, head, and claws. Scald in water at approximately 80°C for about 2 minutes, then scrape off the black outer skin and the membrane on the plastron. Rinse clean and cut into pieces for later use. Peel fresh Chinese yam (Dioscorea opposita) and cut into rolling-cut chunks; immediately soak in light salt water to prevent oxidation and discoloration. Briefly rinse longan flesh (Dimocarpus longan), red jujube (Ziziphus jujuba), and goji berry (Lycium barbarum) in warm water. Slice fresh ginger (Zingiber officinale) and set aside.

Step 2: Blanch the soft-shell turtle to remove the fishy odor. Add approximately 1500 ml of fresh water to a pot, then place the turtle pieces in along with 5 g of ginger slices and 10 ml of Shaoxing wine. Bring to a boil over high heat, then continue boiling for 3–5 minutes. Skim off any foam that rises to the surface, remove the turtle pieces, rinse them thoroughly with warm water, and drain well. This step is critical—it effectively eliminates the fishy taste and residual blood, resulting in a clear broth with a pure, clean flavor.

Step 3: Formal Simmering. Place a clay pot or ceramic casserole on the stove. Add the blanched soft‑shelled turtle pieces, fresh Chinese yam pieces (Dioscorea opposita), longan arils (Dimocarpus longan), red dates (Ziziphus jujuba), and the remaining ginger slices. Pour in 2500 ml of clean water (enough to submerge the ingredients by about 5 cm) and the remaining yellow rice wine. Bring to a boil over high heat, then reduce to a low flame and simmer gently for 1.5 hours, until the turtle meat is tender and the broth turns slightly milky white.

Step 4: Seasoning and finishing. Add Lycium barbarum (goji berry) to the pot and continue simmering for 5–10 minutes. Then, season with an appropriate amount of salt according to personal taste, stir gently, and turn off the heat. Do not overcook the goji berries, as prolonged boiling may cause sourness and affect the soup’s flavor. Cover the pot and let it simmer for about 5 minutes before serving. When ladling the soup, the soft-shelled turtle shell can be removed and arranged on the plate as a garnish, symbolizing “full vitality.”

Drinking Tips

This decoction should be taken on an empty stomach before meals, 200–250 ml per serving, 2–3 times per week. A continuous course should not exceed two weeks as one cycle, after which a one-week interval is recommended before further tonification to avoid over-nourishing. It is most effective when consumed in autumn and winter; in hot summer, the dosage may be reduced or temporarily suspended.

2. It is recommended to consume the soft-shelled turtle (Pelodiscus sinensis) meat together with Chinese yam (Dioscorea opposita) when drinking the soup for more comprehensive nutrition. The calipash of the soft-shelled turtle is rich in gelatin and is the most nourishing part—do not discard it. If the soup is not consumed in one sitting, it can be stored sealed in the refrigerator, but should not exceed 24 hours. Before drinking again, it must be thoroughly reheated until boiling.

3. While taking this decoction, maintain a light diet and avoid consuming raw/cold, greasy, or pungent foods, as well as radish, strong tea, and crab. If concurrently taking Chinese herbal medicine, it is recommended to space them by at least one hour. Should abdominal distension, diarrhea, or heat signs (上火) occur after consumption, discontinue use and consult a TCM practitioner to adjust the formula.
