Introduction to Medicinal Diet
Paeonia and Ophiopogon Crucian Carp Soup is a classic medicinal dietary soup that originated among the folk of Jiangnan and was later refined by families of Traditional Chinese Medicine practitioners, with a history of over a hundred years. The soup features crucian carp (Carassius auratus) as the sovereign ingredient, combined with the medicinal herbs white peony root (Paeonia lactiflora) and dwarf lilyturf tuber (Ophiopogon japonicus), supplemented by common ingredients such as fresh ginger (Zingiber officinale) and red jujubes (Ziziphus jujuba). It is gently simmered over low heat, resulting in a milky white broth with a pure and mellow flavor, offering dual benefits of medicinal nourishment and dietary support. In folk tradition, this soup is often regarded as an excellent restorative for the seasonal transition into autumn, particularly suitable for individuals with yin and blood deficiency (yin xue kui xu) and insufficient body fluids (jin ye bu zu).
The brilliance of this medicinal food lies in the principle that “the medicine leverages the food’s power, and the food amplifies the medicine’s efficacy.” Crucian carp itself has tender flesh and rich nutrition, serving to tonify deficiency and consumption and fortify the spleen and stomach. Meanwhile, Paeonia lactiflora (white peony) soothes the liver and nourishes the blood, while Ophiopogon japonicus (dwarf lilyturf) moistens the lungs and generates fluids. When these two herbs are cooked together with crucian carp, they neither render the medicinal properties too aggressive to damage the upright (healthy qi), nor do they fail to fully extract the active constituents into the rich flavor of the fish broth. It is for this reason that Paeonia-Ophiopogon Crucian Carp Soup enjoys the reputation in traditional medicinal food science of being “moist-nourishing without cloying, and clear-nourishing without being cold”—a balanced, harmonizing soup suitable for all seasons.
Efficacy of Medicinal Diet
Nourish yin to moisten dryness, nourish blood to calm the spirit.
In terms of overall efficacy, the most prominent function of the White Peony and Ophiopogon Crucian Carp Soup is to nourish yin and moisten dryness. The Ophiopogon japonicus (Dwarf Lilyturf Tuber) in the soup effectively replenishes the body’s fluids, alleviating symptoms such as dry mouth and tongue, dry and sore throat, and dry skin caused by yin deficiency with effulgent fire. Meanwhile, the Paeonia lactiflora (White Peony Root) excels in nourishing blood and softening the liver, improving conditions like sallow complexion, dizziness, palpitations, insomnia, and dream-disturbed sleep due to blood deficiency. The synergistic effect of these two herbs makes this soup a powerful ally in resisting the “dryness pathogen” during autumn and winter.
Fortify the Spleen, supplement deficiency, and regulate the Middle Jiao.
Crucian Carp (Carassius auratus) serves as the sovereign herb, with its actions of fortifying the spleen and draining dampness, harmonizing the middle and tonifying deficiency recorded as early as the *Compendium of Materia Medica* (*Bencao Gangmu*). After slow simmering, the high-quality protein and various amino acids from the crucian carp dissolve into the broth, making it easily absorbed by the body. This remedy is particularly suitable for individuals with Spleen and Stomach Deficiency, poor appetite, postpartum deficiency, or those convalescing after illness. Additionally, Ginger (*Zingiber officinale*) is added to warm the middle and disperse cold, remove fishy odor and enhance flavor, while Red Dates (*Ziziphus jujuba*)* tonify qi and nourish blood, harmonizing the various medicinals—together, they augment the tonic effect of the entire soup.
Functions of Traditional Chinese Medicine
Under the guidance of traditional Chinese medicine theory, the formulation of Crucian Carp Decoction with White Peony Root and Ophiopogon follows the principle of “sovereign, minister, assistant, and envoy” in herbal配伍. In this formula, Crucian Carp (Carassius auratus) serves as the sovereign, entering the Spleen (SP) and Stomach (ST) meridians, with the function of fortifying the spleen and draining dampness, warming the middle and tonifying deficiency. White Peony Root (Paeonia lactiflora, Bai Shao) acts as a minister, entering the Liver (LR) and Spleen (SP) meridians, excelling in nourishing blood and softening the liver, relaxing tension and alleviating pain, particularly effective for treating restlessness, irritability, and distending pain in the chest and rib-side due to blood deficiency with liver hyperactivity. Ophiopogon (Ophiopogon japonicus, Mai Dong) also serves as a minister, entering the Heart (HT), Lung (LU), and Stomach (ST) meridians, capable of nourishing yin and clearing heat, moistening the lungs and generating fluids, providing significant improvement for dry cough due to lung dryness and thirst from fluid damage.
Fresh Ginger (Zingiberis Rhizoma Recens) and Chinese Red Date (Jujubae Fructus) serve as adjuvant herbs: Fresh Ginger warms the Middle Jiao, dispels Cold, descends rebellious Qi and stops vomiting; Chinese Red Date tonifies the Middle Jiao, boosts Qi, nourishes Blood and calms the Spirit. Together, they not only restrain the cold-natured quality of Ophiopogonis Radix (Mai Dong) and Paeoniae Radix Alba (Bai Shao), but also enhance the savory flavor of the decoction. Looking at the formula as a whole, it harmonizes the Liver, Spleen, and Lung simultaneously, while tonifying both Yin-Blood and Body Fluids. It thus safeguards the acquired foundation—the Spleen and Stomach—while nourishing Yin-Blood and moistening the Lung. This embodies the core TCM principles of “preventive treatment” (zhi wei bing) and “holistic regulation” (zheng tiao yang).
Indications
Peony and Ophiopogon Crucian Carp Soup is especially suitable for individuals with yin-blood deficiency and insufficiency of body fluids. Such people often present with dry mouth and throat, dry and itchy skin, dry eyes, withered hair, dry stools, and are prone to irritability, insomnia, and heat in the palms and soles. If you work for long periods in an air-conditioned environment, or frequently stay up late or overuse your eyes, leading to consumption of yin fluids and deficient fire flaring upward, then this soup can greatly help to nourish yin and blood, and clear and moisten the organs.
Additionally, individuals with Spleen and Stomach Deficiency and weak digestive function are the primary candidates for this soup. After prolonged simmering, the crucian carp becomes tender with softened bones, and the broth is rich in easily absorbable small-molecule proteins and amino acids, placing no burden on the gastrointestinal tract. Combined with the warming-center effect of ginger (Zingiber officinale) and red dates (Ziziphus jujuba), it effectively improves Spleen Deficiency symptoms such as poor appetite, postprandial abdominal distension, mental fatigue, and lassitude. Postpartum women, post-surgical recovery patients, and those engaged in long-term mental labor, excessive rumination, and stealthy consumption of Heart Blood may also consume this soup once or twice per week to achieve significant regulating and tonifying effects.
Contraindicated populations
Despite the balanced nature of the White Peony–Ophiopogon–Crucian Carp Soup (Paeonia lactiflora Root–Ophiopogon japonicus Root–Carassius auratus Soup), certain individuals should use it with caution or avoid it altogether. First, those with Spleen and Stomach Yang Deficiency (spleen–stomach vacuity cold, Middle Jiao yang insufficiency) should refrain from excessive consumption. Such individuals typically present with loose stools, cold pain in the abdomen, cold limbs, and symptoms that worsen with cold exposure. Since both Ophiopogon (Radix Ophiopogonis) and White Peony (Radix Paeoniae Alba) are mildly cold in nature, they may aggravate the deficiency–cold pattern. It is recommended that these individuals increase the amount of Fresh Ginger (Zingiber officinale Rhizoma recens) when consuming the soup, or add a small amount of Cassia Bark (Cinnamomum cassia Cortex) and Dried Ginger (Zingiber officinale Rhizoma siccatum) to warm the Middle Jiao and disperse cold.
Furthermore, it is not suitable for consumption during the early stages of external invasion of wind-cold or wind-heat, when the exterior pathogen has not yet been resolved. Mai Dong (Ophiopogon japonicus) has the property of retaining pathogenic factors, while Bai Shao Yao (Paeonia lactiflora, White Peony) is sour and astringent to consolidate yin; both are unfavorable for the outward dispersion of external pathogens. If you are currently in an acute infection phase, such as common cold with fever, cough with copious phlegm, nasal congestion, and rhinorrhea, you should temporarily discontinue consumption and wait until the exterior pattern is resolved before proceeding with tonification. Additionally, those with fish allergies, pregnant women (especially during the first trimester), and patients with severe renal insufficiency requiring strict control of protein intake should determine suitability for consumption under the guidance of a physician.
Ingredient formulation ratio
Here is the classic formula and precise proportions for the White Peony and Dwarf Lilyturf Crucian Carp Soup (calculated for 2-3 servings): One fresh Crucian Carp (Carassius auratus), approximately 400 g (preferably one with a well-proportioned body, bright red gills, and intact scales); White Peony Root (Paeonia lactiflora) 10 g, Dwarf Lilyturf Tuber (Ophiopogon japonicus) 10 g, Fresh Ginger (Zingiber officinale) 5 slices (approximately 15 g), Red Jujube (Ziziphus jujuba) 6 pieces (approximately 30 g), Salt 2 g (for final seasoning), and Water 2000 ml (approximately 8 cups).
If the aim is to enhance the qi-supplementing effect, an additional 10 g of Astragalus membranaceus (Huangqi) can be added. If there is significant abdominal distension due to qi stagnation, also add 3 g of Citri Reticulatae Pericarpium (Chenpi) to regulate qi and harmonize the stomach. It is essential to note that the Paeoniae Radix Alba (Baishao) and Ophiopogonis Radix (Maidong) should be selected as properly processed decoction pieces; do not use raw, unprocessed products or arbitrarily alter the dosage. For the crucian carp (Carassius auratus), it is best to use a freshly caught and killed specimen. Frozen fish or fish that has been dead for an extended period has a strong fishy smell, which will directly affect both the taste and medicinal efficacy of the soup.
Preparation Method
Step 1: Process the Medicinal Materials
Fresh crucian carp (Carassius auratus) is killed, scaled, gills removed, and eviscerated. The black membranes and blood inside the abdominal cavity are thoroughly rinsed under running clean water. After draining, make three diagonal cuts on each side of the fish. Rub a small amount of salt and cooking wine evenly over the fish and marinate for 10 minutes. White Peony Root (Paeonia lactiflora) and Dwarf Lilyturf Tuber (Ophiopogon japonicus) are quickly rinsed once with clean water to remove surface dust. Chinese Dates (Ziziphus jujuba) are washed and pitted; Fresh Ginger (Zingiber officinale) is sliced.
Step 2: Pan-fry the fish to remove the fishy odor.
Take a clay pot or stainless steel soup pot, place it over heat and warm it up. Add a small amount of cooking oil (about 10 ml). When the oil reaches approximately 60% hot, add the crucian carp. Fry over medium heat until both sides are golden brown and slightly scorched. Drizzle a small amount of yellow rice wine or rice wine along the edge of the pot to remove fishy odor and enhance aroma. This step is crucial for achieving a milky white broth and rich flavor; do not skip it.
Step 3: Simmer over gentle heat
Transfer the fried crucian carp along with the ginger slices into a soup pot. Add Radix Paeoniae Alba (White Peony Root), Radix Ophiopogonis (Dwarf Lilyturf Root), Fructus Jujubae (Chinese Dates), and 2000 ml of boiling water (note: always use boiling water—this is the secret to achieving a milky white broth). Bring to a boil over high heat, then reduce to low heat and simmer gently for 40 minutes, maintaining a slight bubbling. During this time, avoid opening the lid frequently to prevent the aroma from dissipating.
Step 4: Season and remove from the pot.
After 40 minutes of simmering, use a fine-mesh strainer to remove the solids (fish bones and herb residue), retaining only the liquid. Add 2 grams of salt, stir well, and ladle into bowls. For a richer texture, you may also shred the fish meat and return it to the soup before serving. Note that salt should be added last; adding it too early will cause protein coagulation, affecting the soup’s umami and nutrient extraction.
Drinking Tips
1. Best time to consume: It is recommended to drink it warm between 9:00–11:00 (Si hour, when the Spleen Meridian (SP) is predominant) or 17:00–19:00 (You hour, when the Kidney Meridian (KI) is predominant). During these periods, the Spleen and Stomach are most efficient in transformation and transportation, allowing the medicinal constituents of the decoction to be fully absorbed by the body. Avoid drinking on an empty stomach, and refrain from consumption within 2 hours before bedtime, as this may increase nocturnal urination frequency and disrupt sleep.
2. Frequency and Dosage: For general daily regulation, consume 1–2 times per week, with each serving of 200–250 ml being appropriate. Do not overindulge; consistent long-term adherence is key. If used as an adjunctive treatment for certain chronic deficiency conditions, it can be taken continuously for 3 weeks followed by a 1-week break to observe the body’s response and avoid the development of tolerance.
3. Compatibility and Contraindications: During the consumption of this decoction, a light diet is recommended. Avoid simultaneous intake of spicy, greasy, or raw and cold foods (such as hotpot, ice cream, sashimi, etc.) to prevent interference with the medicinal effects. Additionally, this decoction should not be taken together with foods that are antagonistic to fish (such as certain cold-natured fruits and teas). It is also advised to avoid consuming strong tea or coffee within half an hour before or after drinking the decoction, as tannic acid may bind with the medicinal components and reduce the absorption rate.
