Tangerine Peel and Costus Root Lean Meat Soup: Benefits & Recipe

Introduction to Medicinal Diet

Chenpi (tangerine peel) and Muxiang (costus root) lean pork soup is a classic medicinal diet originating from the Lingnan region, embodying the traditional Chinese medicinal dietary principle of “regulating qi and harmonizing the middle jiao.” This soup combines two core herbs—Chenpi (Citri Reticulatae Pericarpium) and Muxiang (Aucklandiae Radix)—with lean pork (pork loin) that tonifies the middle jiao and boosts qi, simmered slowly over a gentle flame. The broth is clear and bright, with a distinctive aroma that blends the mellow, aged fragrance of Chenpi with the crisp, refreshing scent of Muxiang. The overall flavor is savory without being greasy, making it especially suitable for consumption during seasons of heavy dampness or when the spleen and stomach’s transportation and transformation function is suboptimal.

In folk medicine, Chenpi (Citri Reticulatae Pericarpium, dried tangerine peel) and Muxiang (Aucklandiae Radix, costus root) lean pork soup is often used as a supportive remedy for epigastric distension and fullness, as well as poor appetite. Chenpi, one of the “Three Treasures of Guangdong,” has a long history in Chinese medicinal cuisine, while Muxiang has been highly regarded by physicians throughout the ages for its outstanding ability to move qi and relieve pain. The combination of these two ingredients not only strengthens the function of regulating the Spleen and Stomach (Pi and Wei) but also enriches the flavor profile of the soup, making it a nourishing dish that balances health benefits with everyday taste.

Efficacy of Medicinal Diet

The core efficacy of Pericarpium Citri Reticulatae (tangerine peel) and Radix Aucklandiae (costus root) Lean Pork Soup is to regulate qi and strengthen the spleen, as well as to stimulate appetite and promote digestion. Tangerine peel excels at regulating the qi mechanism of the middle jiao, alleviating abdominal distension and belching caused by qi stagnation; costus root warms and unblocks qi, providing significant relief for abdominal distension and pain specifically due to spleen and stomach qi stagnation. Together, they effectively regulate gastrointestinal motility, promote the secretion of digestive fluids, help the body eliminate metabolic wastes in a timely manner, and restore the digestive system to a balanced state.

In addition, lean pork meat, as a high-quality source of protein, provides energy while also nourishing yin and moistening dryness, as well as supplementing the middle and boosting qi. This soup is generally mild in nature. While dispelling damp turbidity and regulating qi movement, it also protects stomach qi, achieving the effect of “simultaneously attacking and supplementing.” With long-term moderate consumption, it can help improve sub-health conditions such as a heavy damp constitution and weak digestive function, leaving the body feeling relaxed and comfortable.

The Role of Traditional Chinese Medicine

Regulate qi and transform dampness, restore the ascending and descending.

From the perspective of Traditional Chinese Medicine, the Spleen and Stomach reside in the Middle Jiao and serve as the pivot for the ascending and descending of qi movement. When dietary irregularities or external invasion of Dampness occur, the Spleen and Stomach’s function of “ascending the clear and descending the turbid” is easily obstructed, leading to symptoms such as epigastric and abdominal fullness, and sticky stools. Citri Reticulatae Pericarpium (Tangerine Peel), with its acrid, dispersing and bitter, descending properties, dries Dampness, transforms Phlegm, regulates qi, and harmonizes the Middle, and is particularly adept at addressing Dampness-Obstruction with Qi Stagnation in the Middle Jiao. Aucklandiae Radix (Costus Root) specifically targets gastrointestinal qi stagnation; its aromatic, penetrating nature awakens the transportation and transformation ability of the Spleen and Stomach. When combined, one dries and the other moves, together restoring the physiological rhythm of Spleen ascending and Stomach descending.

Harmonize the Liver and Spleen, Stop Pain and Calm the Middle

Aucklandia Root (Mu Xiang), in addition to entering the Spleen and Stomach meridians, also enters the Large Intestine and Gallbladder meridians. For Liver-Spleen disharmony and abdominal spasmodic pain caused by emotional stress or consumption of raw/cold foods, it has the effects of warming, unblocking, and harmonizing. Tangerine Peel (Chen Pi) prevents cloying and stomach-obstructing properties of tonic ingredients, ensuring that the soup fulfills its nourishing function without increasing digestive burden. This entire medicated diet, by regulating Qi movement (Qi mechanism) and drying/transforming Dampness turbidity, enables the proper distribution of “Qi” and “Water” in the body, thereby alleviating various discomforts due to Qi stagnation and Dampness obstruction.

Target Population

This medicinal food is especially suitable for modern individuals with Spleen and Stomach Deficiency and Qi Stagnation. Specific manifestations include: epigastric fullness with even slight dietary indiscretions, poor appetite, frequent belching, or postprandial drowsiness and loose stools. For young professionals experiencing gastrointestinal dysfunction due to high work stress and irregular diet and lifestyle, as well as middle-aged and elderly friends with declining digestive function, this soup serves as a gentle and sustained dietary therapy option.

Additionally, individuals living in damp climates, those who often experience a heavy and fatigued body, or present with a white greasy tongue coating are also suitable for consuming Chenpi (Tangerine Peel) and Muxiang (Costus Root) Lean Meat Soup to assist in dispelling dampness and regulating Qi circulation. During seasonal transitions, especially at the junction of summer and autumn when dampness is more prevalent, using this soup as a daily household health tonic can help the body transition smoothly and enhance the Spleen and Stomach’s resilience against external dampness.

Contraindicated Populations

Although the Tangerine Peel and Costus Root Lean Meat Soup (Citri Reticulatae Pericarpium and Aucklandiae Radix with pork soup) is relatively mild in nature, it is not suitable for everyone. Individuals with internal excess fire or yin deficiency with effulgent fire should use it with caution. Specifically, if symptoms of internal exuberance of fire-heat are present—such as dry mouth and tongue, sore throat, bleeding gums, scanty and dark yellow urine, or dry and bound stool—this soup should be avoided, as both Tangerine Peel (Citri Reticulatae Pericarpium) and Costus Root (Aucklandiae Radix) are warm-natured medicinals that may exacerbate the fire-heat.

Pregnant women and those during menstruation should consult a qualified medical professional before consumption. Since Costus Root (Saussurea costus) has certain effects of promoting qi circulation and activating blood, constitutionally sensitive pregnant women may experience discomfort after consuming it in large amounts. Additionally, individuals allergic to Tangerine Peel (Citri Reticulatae Pericarpium) or Costus Root, as well as those currently suffering from acute gastroenteritis accompanied by high fever or severe vomiting and diarrhea, should temporarily avoid consumption until the condition stabilizes, and then decide whether to take it based on the body’s response.

Ratio of Ingredients in the Formula

To prepare a standard Tangerine Peel and Costus Root Lean Meat Soup, the following precise formula is recommended: Pericarpium Citri Reticulatae (dried tangerine peel) 6 g, Radix Aucklandiae (costus root) 5 g, lean pork 250 g, fresh ginger (Rhizoma Zingiberis Recens) 3 slices (approx. 6 g), and Fructus Jujubae (Chinese red date) 2 pieces (pitted, approx. 10 g). This formulation emphasizes “small dosages and light medicinal action,” utilizing the aromatic and functional properties of the herbs to regulate the Spleen and Stomach without overpowering the natural umami of the pork. It embodies the core principle of medicinal cuisine: “therapeutic substances are concealed within daily food.”

It is particularly important to note that Mu Xiang (Aucklandia lappa / Saussurea costus) should not be decocted for too long when added to a soup, as its active constituents are volatile and easily lost, thereby reducing its effect of promoting qi and alleviating pain. Therefore, in practice, lean meat and other ingredients that require longer cooking are usually stewed until done, and Mu Xiang is added only briefly near the end of the decoction. For Chen Pi (Citri Reticulatae Pericarpium / tangerine peel), it is recommended to soak it in warm water for a short time beforehand and scrape off the inner pith to reduce bitterness, resulting in a soup with a purer, more balanced and sweet flavor.

Preparation method

Step 1: Prepare the ingredients. Rinse the lean pork meat and cut into 2 cm cubes. Place the pork in a pot of cold water, add 2 slices of fresh ginger (Zingiber officinale), and bring to a boil over high heat. Skim off the foam, then remove the pork and rinse thoroughly with warm water to eliminate blood and fishy odor. Soak dried tangerine peel (Citri Reticulatae Pericarpium, from Citrus reticulata) in warm water for 10 minutes, scrape off the white inner pith with a knife, and cut into fine strips; set aside. Quickly rinse costus root (Aucklandia lappa / Saussurea costus, Radix Aucklandiae) under running water to avoid prolonged soaking that would diminish its aroma. Remove the pits from jujube dates (Fructus Jujubae, from Ziziphus jujuba) and slice the fresh ginger.

Step 2: Simmer the broth. Place the blanched lean meat, shredded Citri Reticulatae Pericarpium (tangerine peel), Jujubae Fructus (red dates), and the remaining slice of fresh ginger (Zingiberis Rhizoma Recens) into a stew pot. Add sufficient water (approximately 1500 ml). Bring to a boil over high heat, then reduce to low heat and simmer for 1 hour. This allows the proteins and amino acids from the lean meat to be fully released, while the medicinal properties of the tangerine peel gently infuse into the broth.

Step 3: Add Muxiang. Ten minutes before turning off the heat, add the washed whole or coarsely crushed Muxiang (Saussurea costus / Costus root) into the soup, cover the pot, and continue simmering on low heat. Note that Muxiang should not be cooked for too long; 10 minutes is sufficient. Finally, season with an appropriate amount of salt (about 2 grams, avoid being too salty), stir well, and turn off the heat. Before serving, remove the Muxiang residue, and ladle the soup and lean meat into a bowl to enjoy.

Drinking Tips

1. For best results, consume half an hour before meals. The Qi-moving action of Chenpi Muxiang Lean Meat Soup (Citri Reticulatae Pericarpium and Aucklandiae Radix) primarily targets the digestive system. Drinking half a bowl warmed before a meal helps to awaken the Spleen and Stomach, promote appetite, and facilitate the digestion and absorption of subsequently consumed greasy or high-protein foods. Avoid consuming large amounts after a heavy meal, as this may increase the burden on the gastrointestinal tract.

2. Drinking cycle suggestion: “Three-day pause.” Although this product has a mild medicinal property, continuous consumption should not exceed 5 days. It is recommended to drink 2 to 3 times per week, one bowl (approximately 200 ml) each time. When self-perceived abdominal distension is reduced and appetite is restored, the frequency can be adjusted to once a week as a health tonic soup. Long-term excessive consumption may lead to Qi depletion and Yin damage, thereby weakening the function of the Spleen and Stomach instead.

3. Please use according to pattern differentiation during the common cold. In the early stage of exterior wind-cold accompanied by headache, nasal congestion, aversion to cold, and absence of sweating, a moderate amount may be consumed to assist in releasing the exterior. However, if the cold presents with wind-heat symptoms such as sore throat with redness, high fever, and yellow phlegm, it is not suitable for consumption. Additionally, the medicinal dregs from the soup (especially Citri Reticulatae Pericarpium – tangerine peel and Zingiberis Rhizoma Recens – fresh ginger) are not recommended for eating, as they may cause a bitter, astringent taste or irritate the stomach and intestines.
