If the Chinese confinement tradition had a single defining element, it would be soup. Throughout the 28 to 40 days of zuo yue zi (坐月子), soup is served at virtually every meal — sometimes twice a day, sometimes more. It is the primary vehicle for herbs, the main source of hydration, the gentlest form of nourishment for a body recovering from the extraordinary act of childbirth.

This is not accidental. Soup occupies its central position in confinement for deeply practical reasons that hold up under both traditional and modern scrutiny. But preparing daily confinement soups — each with different herbal formulas, changing with each stage of recovery — is also one of the most demanding aspects of the tradition.

This guide explores why soup matters so much, what the traditional 28-day soup progression looks like, and how modern approaches are making this practice more accessible to families today.

Why Soup Is the Centerpiece of Confinement

Easy to Digest

After childbirth, the digestive system is weakened. In TCM terms, the spleen qi — which governs the transformation and transportation of food — is depleted. Solid, heavy foods can overwhelm this weakened system, leading to bloating, poor nutrient absorption, and fatigue.

Soup addresses this directly. The long simmering process breaks down proteins and other nutrients into a form that requires minimal digestive effort. The body can absorb nourishment from a well-made broth even when its digestive capacity is compromised.

Modern nutritional science supports this principle. Research on postoperative and post-illness nutrition consistently shows that liquid and semi-liquid foods are better tolerated and more efficiently absorbed during recovery periods (Weimann et al., 2017).

Hydrating

Breastfeeding mothers need significantly more fluid — approximately 700 ml per day above normal requirements, according to the European Food Safety Authority (EFSA, 2010). In the confinement tradition, mothers are often advised to limit cold water intake. Soup — along with herbal tea — becomes the primary source of hydration, delivering fluid in a warming, nourishing form that aligns with TCM principles.

A Vehicle for Herbs

Many of the most important confinement herbs — dang gui (当归), astragalus (huang qi, 黄芪), eucommia bark (du zhong, 杜仲) — are too tough, bitter, or concentrated to eat directly. Simmering them in soup for 1.5 to 3 hours extracts their active compounds into the broth, making them palatable and bioavailable.

This is not merely folk wisdom. Research on herbal decoction — the traditional method of simmering herbs in water — confirms that prolonged heating extracts a significant proportion of water-soluble bioactive compounds, including polysaccharides, saponins, and flavonoids (Zhang et al., 2012).

Collagen and Gelatin

Many confinement soups feature collagen-rich ingredients: pig trotters, chicken feet, pork bones, fish heads. Extended simmering breaks down collagen into gelatin, producing the characteristic silky, slightly gelatinous consistency of a good confinement broth. Gelatin provides glycine and proline — amino acids involved in tissue repair, gut lining maintenance, and joint health.

The principle is elegant in its simplicity: the body is depleted and its digestion is weak, so you deliver maximum nourishment in the most easily absorbed form possible — warm, liquid, herb-infused, and collagen-rich.

The Traditional 28-Day Soup Progression

Like the broader confinement diet, the soup programme follows a staged progression. Each week features different soups with different herbal formulas, matched to the body’s changing needs.

Week 1: Cleansing Soups (Days 1-7)

The focus in Week 1 is gentle cleansing — supporting uterine contraction, encouraging lochia discharge, and nourishing without overwhelming.

Sheng Hua Tang (生化汤, Birth Transformation Soup)

This is the most important formula of Week 1 — and one of the most well-known postpartum prescriptions in TCM. The name literally means “generating and transforming,” referring to its ability to generate new blood while transforming (discharging) old blood.

Classical formula: - Dang gui (当归) 24 g — nourishes and invigorates blood - Sichuan lovage (chuan xiong, 川芎) 9 g — promotes blood circulation, relieves pain - Peach kernel (tao ren, 桃仁) 6 g — breaks blood stasis - Roasted ginger (pao jiang, 炮姜) 2 g — warms the uterus - Liquorice (gan cao, 甘草) 2 g — harmonises the formula

Preparation: Simmer herbs in 600 ml of water for 30-40 minutes. Strain and drink the broth warm, typically once or twice daily for 5-7 days.

Research published in the Journal of Ethnopharmacology has found that sheng hua tang may promote uterine contraction and support postpartum uterine involution, though more rigorous clinical trials are needed (Chuang et al., 2009).

Pork Liver Soup

A simple, light soup featuring thinly sliced pork liver cooked in ginger and sesame oil broth. Pork liver is exceptionally rich in iron (17.9 mg per 100 g) and vitamin A, addressing the immediate need for blood replenishment after delivery.

Simple recipe: - 200 g pork liver, thinly sliced - 30 g old ginger, sliced - 2 tablespoons black sesame oil - 500 ml water - Salt to taste

Fry ginger in sesame oil until fragrant. Add water and bring to a boil. Add liver slices and cook for 3-4 minutes (do not overcook). Season and serve.

Light Fish Soup

A clear fish broth made with fresh-water fish (carp or crucian carp is traditional) and ginger. Gentle, hydrating, and mildly nourishing — appropriate for a digestive system that is just restarting.

Week 2: Blood-Nourishing Soups (Days 8-14)

The second week introduces more substantive herbal formulas as the body’s digestive capacity improves and the need for active blood-building increases.

Ba Zhen Tang (八珍汤, Eight Treasure Soup)

One of the most celebrated formulas in all of TCM, ba zhen tang combines two classical formulas — si jun zi tang (Four Gentlemen Decoction, for qi) and si wu tang (Four Substances Decoction, for blood) — into a single, comprehensive treatment for dual qi and blood deficiency.

Formula (typically cooked with chicken or pork ribs): - Dang gui (当归) 10 g - White peony (bai shao, 白芍) 10 g - Prepared rehmannia (shu di, 熟地) 12 g - Sichuan lovage (chuan xiong, 川芎) 6 g - Codonopsis (dang shen, 党参) 10 g - White atractylodes (bai zhu, 白术) 10 g - Poria (fu ling, 茯苓) 10 g - Liquorice (gan cao, 甘草) 5 g

Preparation: Combine herbs with 500-600 g of chicken pieces or pork ribs and 2 litres of water. Bring to a boil, skim, then simmer on low heat for 2-2.5 hours. Season with salt. Drink the broth and eat the meat.

Fish and Papaya Soup

Week 2 is also when lactation-supporting soups are introduced. Fish and green papaya soup — milky white, rich in protein, and traditionally believed to promote breastmilk — becomes a regular feature. See our confinement recipes guide for the full recipe.

Pork Kidney and Eucommia Soup

Pork kidneys braised with du zhong (杜仲, eucommia bark) and ginger, specifically targeting lower back strengthening. This “like treats like” approach — using animal kidney to nourish the human kidney system — is characteristic of TCM dietary therapy.

Week 3: Tonifying Soups (Days 15-21)

By Week 3, the body has cleared and stabilised. It is now ready for the richest, most deeply nourishing soups of the entire programme.

Gui Pi Tang (归脾汤, Restore the Spleen Decoction)

This formula targets the spleen and heart — addressing fatigue, poor appetite, anxiety, and the emotional fragility that many mothers experience by the third week postpartum.

Key ingredients (in soup form, cooked with chicken): - Astragalus (huang qi, 黄芪) 15 g - Codonopsis (dang shen, 党参) 10 g - Dang gui (当归) 10 g - White atractylodes (bai zhu, 白术) 10 g - Poria (fu ling, 茯苓) 10 g - Longan flesh (gui yuan, 桂圆) 10 g - Sour jujube seed (suan zao ren, 酸枣仁) 10 g - Polygala (yuan zhi, 远志) 5 g - Liquorice (gan cao, 甘草) 5 g

Preparation: Simmer with a whole black chicken or 500 g chicken pieces in 2 litres of water for 2.5-3 hours. The resulting broth is rich, aromatic, and deeply nourishing.

Pig Trotter Soups

Week 3 is the prime time for collagen-heavy pig trotter soups — whether the Cantonese vinegar version (zhu jiao cu, 猪脚醋), pig trotters with peanuts, or pig trotters with papaya. These soups provide abundant protein, collagen, and are traditionally prized for supporting lactation.

Black Chicken Herbal Soup

Black-bone chicken (wu gu ji, 乌骨鸡) simmered with dang gui, astragalus, red dates, and goji berries. This is one of the most deeply nourishing soups in the confinement repertoire. See our recipes page for the full recipe.

Week 4: Comprehensive Strengthening Soups (Days 22-28)

The final week uses the most comprehensive formulas, preparing the body for life after the protected confinement period.

Shi Quan Da Bu Tang (十全大补汤, Perfect Major Supplementation Decoction)

This is the “everything” formula — the most all-encompassing tonifying prescription in TCM. It builds on ba zhen tang by adding astragalus (for qi and immunity) and cinnamon bark (rou gui, 肉桂, for warming yang).

The complete formula (ten herbs): All eight herbs of ba zhen tang, plus: - Astragalus (huang qi, 黄芪) 15 g - Cinnamon bark (rou gui, 肉桂) 3 g

Preparation: Simmer with chicken, pork, or lamb and 2 litres of water for 2.5-3 hours. This produces a rich, warming, deeply aromatic broth.

The name shi quan da bu literally means “ten complete great tonification” — reflecting the formula’s ambition to address every dimension of postpartum deficiency. Research has documented immunomodulatory and haematopoietic properties of this formula (Nakamoto et al., 2013).

Varied Protein Soups

Week 4 also features a wider variety of soup bases — fish soups, lamb soups (if the mother’s constitution tolerates them), and lighter broths — reflecting the transition toward a more normal, varied diet.

The Challenge of Daily Soup Preparation

Understanding the traditional soup progression is one thing. Executing it daily for 28 days is quite another.

Consider what is involved:

  • Sourcing herbs. Many of the formulas above contain 8-10 different TCM herbs, most of which are not available at ordinary supermarkets. They require a visit to a Chinese herbal medicine shop or a reliable online supplier — and the knowledge to select quality ingredients.
  • Knowing the formulas. Each week requires different herbal combinations in specific proportions. Getting these right requires either deep familiarity with TCM or detailed guidance.
  • Time and effort. A proper confinement soup takes 2-3 hours of simmering. Preparing this daily — while caring for a newborn, recovering from childbirth, and managing sleep deprivation — is a significant burden.
  • Consistency. The benefit of the soup programme comes from its consistency — daily nourishment, following the staged progression. Missed days or improvised substitutions reduce its effectiveness.

Traditionally, this responsibility fell to the mother’s own mother or mother-in-law, or to a professional yue sao (月嫂, confinement nanny). In many modern families — particularly those in the diaspora, nuclear family households, or where both parents work — this daily support is not available.

Modern Approaches: Pre-Portioned Soup Programmes

This practical gap has given rise to a modern alternative: pre-portioned confinement soup kits that follow the traditional staged progression.

The concept is straightforward. Rather than sourcing and measuring individual herbs, a mother receives daily soup portions — each containing the appropriate herbal formula for that stage of her recovery, paired with the right base ingredients (chicken, pork ribs, fish). The ingredients change day by day, following the Week 1-2-3-4 progression described above.

This approach offers several advantages:

  • Authenticity without expertise. The formulas are designed by TCM practitioners, ensuring proper herb combinations and proportions.
  • Convenience. Preparation time is reduced dramatically — from hours of sourcing and measuring to simply simmering a pre-portioned kit.
  • Consistency. The staged progression is built in, so mothers follow the traditional timeline without needing to plan each day’s formula.
  • Quality control. Reputable suppliers use food-grade, tested herbs — addressing the quality concerns that can arise when sourcing herbs independently.

This is not a replacement for the full confinement experience — the warmth of a family member cooking daily, the ritual of preparing food with intention, the presence of a knowledgeable yue sao. But for families who lack access to these traditional supports, it offers a way to preserve the nutritional core of the tradition.

The goal is not perfection — it is nourishment. Whether your soups are prepared by your mother, a confinement nanny, a soup programme, or yourself between nappy changes, the act of nourishing your body with warm, herbal, carefully staged soups honours the wisdom of the tradition.

Tips for Making Confinement Soups at Home

For those who do prepare soups at home, here are practical guidelines:

Equipment

  • A large clay pot or ceramic casserole is ideal — it distributes heat evenly and is the traditional vessel for medicinal soups
  • A slow cooker is a practical alternative, allowing soups to simmer safely for hours unattended
  • A fine-mesh strainer for removing herb residue before serving

Technique

  1. Always blanch bones and meat first. Bring a pot of water to a rolling boil, add the meat, blanch for 3-5 minutes, drain, and rinse. This removes impurities and results in a cleaner broth.
  2. Rinse herbs briefly under running water before use to remove any dust or residue.
  3. Start with cold water when building the soup. This allows for a more gradual extraction of flavours and nutrients.
  4. Bring to a vigorous boil, then reduce to a low simmer. The initial boil is important for food safety; the long, gentle simmer is what extracts nutrients and creates depth of flavour.
  5. Do not lift the lid frequently. Each time the lid is removed, heat and steam escape, extending cooking time and reducing broth concentration.
  6. Season at the end. Salt and other seasonings should be added in the last 10-15 minutes of cooking.

Storage

  • Confinement soups keep well in the refrigerator for 2-3 days
  • They can be frozen in individual portions for up to 2 weeks
  • Always reheat thoroughly before serving — bring to a full boil for at least 2 minutes

Soup and the Bigger Picture

Soup is not just food during confinement — it is care made tangible. The act of preparing and serving daily soup is, in many families, an expression of love and respect for the new mother. It is the tradition at its most practical and its most tender.

Whether you follow the full 28-day soup progression or simply incorporate a few of these soups into your postpartum weeks, you are participating in a practice that has nourished millions of mothers across centuries. The warmth of the broth, the depth of the herbs, the intention behind each bowl — these things matter.
