Stewed Pig Lung with Malva Nut: Recipe & Lung Benefits

Introduction to a Traditional Dietary Recipe

“Boat-fruited Sterculia (Pangdahai) and Pig Lung Soup” is a traditional dietary recipe originating from the Lingnan region. It is characterized by its sweet, cold, and moistening properties. Boat-fruited Sterculia (Sterculia lychnophora Hance), also known as “Dahaizi” or “Annanzi,” is the mature seed of a plant in the Sterculiaceae family. It resembles an olive in shape and expands like a sponge when soaked in water. Pig lung is taken from fresh pig lung tissue, which is tender in texture and traditionally associated with the concept of nourishing the corresponding organ. When combined, the soup has a clear broth, a smooth texture, and a mild sweetness mixed with a light meat aroma. It can serve as a daily soup and is also a home-style recipe that may help support respiratory comfort.

This recipe skillfully combines herbs with food ingredients. Through slow simmering, the mucilage and active constituents of *Pang Dahai* (Sterculia lychnophora / Boat Sterculia Seed) are fully released into the soup, while pig lung adds substance and supports the overall nourishing effect. It is suitable for daily maintenance in autumn and winter or in dry environments, especially for individuals who use their voice frequently. In folk practice, it is often used as a supportive dietary approach to help soothe throat discomfort and promote voice clarity. The overall nature is balanced, but attention should be paid to individual constitution when incorporating any dietary practice.

Dietary Support Benefits

The core benefits of this recipe are to help soothe the throat, promote respiratory comfort, and support overall well-being. Sterculia lychnophora (Boat-fruited Sterculia) has a sweet and cooling nature and is traditionally used to help maintain respiratory health and throat comfort. It may provide soothing support for minor throat irritation, dryness, or occasional cough associated with dry environments. Pig lung is traditionally thought to help nourish respiratory health. The combination of the two—one helps clear, one helps nourish—provides a gentle, balancing effect.

From a modern nutritional perspective, Pangdahai (Sterculia lychnophora) is rich in sterculia gum, tragacanth mucopolysaccharides, and various trace elements, which may help maintain moisture in the throat and support normal phlegm clearance. Pig lung contains abundant protein, vitamins, and iron, helping to support the body’s immune function. When stewed together, they not only help maintain respiratory tract moisture but also provide easily absorbable nutrients for the body. This combination is especially suitable for supporting throat comfort during dry seasons or for those who smoke.

The Role of Traditional Herbal Wisdom

Traditional herbal wisdom holds that the lungs appreciate moisture and dislike dryness, and the preparation “Stewed Pig Lung with Sterculia (Pangdahai)” aligns with this physiological characteristic. Sterculia is light in nature and is traditionally used to help maintain open airways, support respiratory function, and soothe heat-related discomfort. Its sweet and cooling properties may help maintain respiratory balance. Pig lung, as a substance of blood and flesh, follows the principle of “like supports like,” directly nourishing the respiratory system and supporting its normal function.

The synergistic effects of these two ingredients manifest at three levels: First, the combination of Pangdahai (Sterculia lychnophora), which helps maintain throat comfort and voice clarity, with pig lung, which supports respiratory health, can assist in both mild voice strain and general respiratory support. Second, the mild bowel-moistening property of Pangdahai, when used in small amounts, paired with the moistening action of pig lung, helps support normal digestive and respiratory function. Third, the slow cooking method allows the ingredients to release their beneficial components gradually, minimizing any potential harshness, thus making it especially suitable for those with occasional heat-related discomfort who still have healthy digestive function.

Key Points of Ingredient Compatibility

It should be noted that the dosage of Pangdahai (Sterculia lychnophora / Boat-fruited Sterculia) should not be excessive; typically, 3 to 5 pieces per person per use is sufficient, as more may cause digestive changes. When cleaning the pig lung, repeatedly rub it with salt or starch to remove any impurities, ensuring the soup’s flavor is pure. The simmering time should be controlled between 1.5 to 2 hours to allow the flavors and nutrients to fully integrate.

Suggested Use

This recipe may be suitable for individuals who experience occasional throat dryness or discomfort due to dry environments or overuse of the voice. It includes: teachers, hosts/anchors, and singers who use their voice frequently and may experience occasional hoarseness or dry throat; those with minor throat irritation or occasional dry cough; as well as people who experience dry air conditions in autumn or in air-conditioned rooms. All such individuals may take it in appropriate amounts.

In addition, smokers and passive smokers who often experience a sensation of throat dryness or occasional morning cough may use this recipe for periodic support. For some older individuals with occasional dry cough or thirst due to mild fluid imbalance, this preparation may also be suitable. Typically, consuming it 2–3 times at the early stage of symptoms may help support comfort.

Considerations

Caution is required for individuals with a constitution of cold sensitivity or weak digestion. Specifically, those with frequent loose stools, aversion to cold, or a pale tongue should avoid use, as the cooling nature of Sterculia lychnophora (Boat-fruited Sterculia), known as Pangdahai, may exacerbate digestive sensitivity. It is also unsuitable during the early stage of a common cold with chills and clear nasal discharge. Pregnant and breastfeeding women should use only after consulting a healthcare professional, as Pangdahai may stimulate bowel movement in some individuals.

Additionally, this recipe is contraindicated for individuals with a pig lung allergy. For serious respiratory conditions, one should not rely solely on this recipe; standard medical care should be prioritized. When giving to children, reduce the dosage and remove the hard shell of *Sterculia lychnophora* (Malva Nut), using only the gelatinous part. Individuals with low blood pressure should also use caution, as Malva Nut may have mild blood pressure-lowering effects in some cases.

Ingredient Formula Proportions

Standard formula (serves 1–2):

• Pang Da Hai (Sterculia lychnophora, Malva nut): 5 pieces (approx. 10 g)
• Fresh pig lung: 300 grams
• Zingiber officinale (Ginger): 4 slices (approx. 10g)
• Lycium barbarum (goji berry): 5 g
• Salt: to taste (about 3 grams, season at the end)
• Rice wine: 10 ml
• Plain water: 1500 ml

Select large, brown-colored, finely wrinkled seeds of Boat-fruited Sterculia (Sterculia lychnophora); for pig lung, choose pieces with a pale red color and good elasticity, avoiding those that are dark or contain blood clots. For single-person consumption, reduce the amount by half proportionally, but the number of Boat-fruited Sterculia seeds should not be less than 3. Goji berries (Lycium barbarum) are used to enhance sweetness and color, but are not essential.

Preparation method

Step 1: Prepare the pig lung. Align the trachea of the pig lung with the faucet, repeatedly fill with water and rinse until the lung lobes turn white and are free of blood. Cut into 3 cm cubes, add salt and starch, scrub for 2 minutes, then rinse with clean water and drain.

Step 2: Blanch to remove impurities. Add cold water to a pot, then add the pig lung pieces, 2 slices of fresh ginger (Rhizoma Zingiberis Recens), and 10 ml of cooking wine. Bring to a boil over high heat, skim off any foam, and continue boiling for 2 minutes. Remove the lung pieces and rinse them with warm water to wash away any remaining foam.

Step 3: Soak and puff the Sterculia lychnophora (Malva nut). Soak the Malva nut in warm water for about 15 minutes to allow it to fully expand. Tear it open and remove the inner core (alternatively, you may keep the core, though the texture will be slightly astringent). Set aside for use.

Step 4: Stewing. Place the blanched pig lung, soaked Boat-fruited Sterculia (Pangdahai), the remaining 2 slices of fresh ginger, and 5 grams of goji berries (Lycium barbarum) into a clay pot. Add 1500 ml of clean water. Bring to a boil over high heat, then reduce to low heat and gently simmer for 1.5 hours.

Step Five: Season and serve. Simmer until the pig lung is tender and the soup turns a light yellow. Add an appropriate amount of salt, stir well, and cook for another 5 minutes before turning off the heat. Remove the ginger slices before serving. Consume both the soup and the solid ingredients together.

Serving Tips

1. Timing of consumption: It is recommended to take it warm, half an hour before meals or one hour after meals, once daily, for three consecutive days as a short-term support. Discontinue once desired comfort is achieved. When used long-term as a maintenance soup, do not exceed two times per week.

2. Precautions for combination: During the course of use, avoid spicy, grilled, fried, and other dry-heat foods to prevent interfering with the soothing effect of the recipe. If concurrently taking other herbs that support throat comfort, maintain an interval of at least half an hour.

3. Preservation and Reheating: If the prepared recipe cannot be consumed in one sitting, filter out the softened residue of Malva nut (Sterculiae Lychnophorae Semen, Pangdahai), then refrigerate the soup and pig lung separately. Consume within 24 hours. When reheating, use low heat and avoid prolonged boiling to prevent destroying beneficial components. For occasional throat dryness, increase Malva nut to 8 pieces, but correspondingly extend the cooking time and observe digestive comfort.
