American Ginseng (Panax quinquefolius) and Lean Pork Soup

Introduction to Medicinal Diet

American Ginseng and Lean Pork Soup is a classic TCM medicinal diet soup, originating from traditional food therapy culture. It is made primarily from American ginseng (Panax quinquefolium) and lean pork, stewed with a small amount of seasonings. American ginseng, also known as huāqí shēn, is native to North America and was introduced to China during the Qing Dynasty, gradually becoming an important herb for nourishing and maintaining health. This soup features a “clear-tonifying” (qīng bǔ) characteristic—unlike the warm-drying nature of Asian ginseng (Rénshēn), it tonifies Qi and nourishes Yin, making it especially suitable for the constitution of modern people.

In the Lingnan region, American Ginseng and Lean Pork Soup (Panax quinquefolium and lean pork soup) is a commonly prepared medicinal food for daily consumption, especially during hot and humid seasons when it is used to clear summer heat and supplement body fluids. The soup is clear in appearance, savory in taste, and carries a distinctive sweet-cool aftertaste characteristic of ginseng. It is highly regarded both as a daily health maintenance tonic and for post-illness recovery. With its simple preparation and readily available ingredients, it is an ideal choice for beginners in medicinal cuisine.

Origins and Culture of Soups

The application of American ginseng (Panax quinquefolius) in Chinese medicinal cuisine originated in the Qing dynasty court, where imperial physicians discovered that this herb has a cool nature yet is tonifying, making it suitable for the royal family and nobility to take during summer supplementation. Among the common people, it gradually became stewed with lean meat, both to neutralize the slight bitterness of ginseng and to enhance the flavor through the umami of meat. Today, this soup has evolved from a medicinal recipe into a nourishing delicacy on the public dining table, embodying the traditional wisdom of “integrating medicine into food.”

Efficacy of Medicinal Food

The primary effects of American Ginseng and Lean Meat Soup are to supplement qi and nourish yin, clear fire and engender fluids. The saponins in American ginseng (Panax quinquefolium) can effectively alleviate fatigue and enhance immunity, while the lean meat provides high-quality protein and essential amino acids. Together, they replenish the body’s depleted qi and blood, making this soup particularly suitable for consumption after profuse sweating or physical exertion. Regular drinking may improve symptoms such as dry mouth and throat, hoarseness, and vexation with insomnia due to deficiency.

From a modern nutritional perspective, American ginseng (*Panax quinquefolius*) is rich in active compounds such as ginsenosides Rb1 and Rg1, which exhibit anti-fatigue, antioxidant, blood glucose-regulating, and memory-enhancing effects. Lean meat is abundant in heme iron and zinc, which help prevent anemia and promote wound healing. Therefore, this soup provides beneficial adjunctive support for suboptimal health conditions, chronic fatigue syndrome, and post-surgical recovery.

Functions of Traditional Chinese Medicine

In TCM theory, American Ginseng (Panax quinquefolium) is cool in nature, sweet and slightly bitter in taste, and enters the Heart (HT), Lung (LU), and Kidney (KI) meridians. Its primary actions are to tonify qi and nourish yin, clear heat and generate fluids. *Bencao Congxin* (New Compilation of Materia Medica) records that American Ginseng “supplements the lung, descends fire, engenders fluids, and eliminates vexation and fatigue.” Pork lean meat, on the other hand, is neutral in nature and sweet in taste, entering the Spleen (SP), Stomach (ST), and Kidney (KI) meridians. It serves to nourish yin and moisten dryness, as well as tonify the middle and supplement qi. When combined, the two herbs—one clearing, one tonifying—complement each other, jointly achieving the effect of “clearing and tonifying.”

American Ginseng and Lean Meat Soup is particularly indicated for the pattern of **Qi and Yin deficiency**, presenting with shortness of breath, fatigue, dry mouth and throat, red tongue with scant coating, and thin, rapid pulse. In this formula, American Ginseng (*Panax quinquefolius*) clears deficient heat and nourishes Lung Yin, directly addressing the deficient fire. The lean meat, by supplementing and benefiting the Spleen and Stomach and transforming fluids to generate body fluids, fundamentally replenishes the source of Yin. Additionally, the warming and dispersing action of Fresh Ginger (*Zingiber officinale*) counteracts the cool nature of American Ginseng, making the entire soup more balanced and easier to assimilate.

Suitable Population

Those with Qi and Yin deficiency are most suitable, including individuals convalescing from a prolonged illness, those with a weak constitution, and people prone to dry mouth and tongue, shortness of breath, and fatigue. Such individuals often experience lack of vitality and profuse sweating with minimal exertion. American ginseng (Panax quinquefolium) and lean meat soup can rapidly replenish depleted Qi and Yin, restoring physical strength.

It is also very suitable for office workers who often stay up late, overuse their brains, and spend long hours facing computers. Modern people live at a fast pace; staying up late, working overtime, and irregular diet can easily lead to “Yin deficiency with effulgent fire”, manifesting as oral ulcers, throat discomfort, insomnia and excessive dreaming, etc. This soup can clear the heart and calm the spirit, nourish Yin and moisten dryness, helping to regulate the body’s condition.

Furthermore, middle-aged and elderly individuals going through menopause, as well as those who smoke frequently and are prone to dry coughs, are also suitable to take this soup as a daily health supplement, consuming it two to three times per week to help alleviate various discomforts caused by Yin Fluid Deficiency.

Contraindications

Patients with Spleen and Stomach Deficiency Cold should not take it in excess. American ginseng (Panax quinquefolius) is cold in nature; if one already has symptoms such as stomach cold with aversion to cold, loose stools, and epigastric and abdominal cold pain, taking it may aggravate deficiency cold, leading to diarrhea or indigestion. For such individuals wishing to tonify, it is recommended to switch to warm-tonifying ginseng (Panax ginseng) or codonopsis (Codonopsis pilosula).

Contraindicated in cases of wind-cold common cold or unresolved exterior excess pathogen. When wind-cold exterior pattern manifestations such as aversion to cold and fever, headache and nasal congestion, cough with white phlegm are present, one should first release the exterior and disperse cold. It is not appropriate to use nourishing substances too early, as this may lock the pathogen inside, making it difficult for the pathogenic qi to be expelled. Similarly, those with internal excess heat or severe damp-heat, presenting with a yellow, greasy tongue coating, are also not suitable.

Use with caution in pregnant women. Although American ginseng (Panax quinquefolius) has no significant toxicity, pregnancy involves a special constitution, so it should only be taken under the guidance of a physician. Additionally, infants and children under three years of age, as well as individuals experiencing acute diarrhea or vomiting, should also discontinue use to avoid increasing the burden on the gastrointestinal tract.

Ingredient proportions in a formula

American ginseng slices (Panax quinquefolius): 5g (approximately 15-20 slices). Choose high-quality, authentic American ginseng, preferably with distinct horizontal striations on the surface, firm texture, and a clear, fragrant aroma. Note: Do not substitute with domestic sun-dried ginseng (Panax ginseng), as their natures and flavors differ.

Lean pork: 150 g, preferably tenderloin or hind leg lean meat, which is low in fat, producing a clear and non-greasy soup. Soak in cold water for half an hour before cutting to help remove blood residue.

Ginger: 3 slices (approx. 6g), used to remove fishy odor and enhance aroma, while neutralizing the cool nature of American Ginseng (Panax quinquefolius) to make the soup more balanced in nature.

Hong Zao (Ziziphus jujuba, Red Date): 3 pieces (approximately 15 g), use after removing the pits. It tonifies the Middle and supplements Qi, nourishes Blood and calms the Spirit, and enhances the sweet flavor of the soup.

Lycium barbarum (Goji berry): 5g (approximately 20 pieces), add during the last five minutes of decoction to avoid prolonged boiling that may degrade the active constituents.

Salt: Approximately 2 grams (used for final seasoning, or may be omitted), adjust according to personal taste. The medicinal diet should follow the principle of being light and bland.

Cooking method

**Step 1: Ingredient preparation.** Cut the lean pork into 2 cm cubes. Place them in a pot of cold water, add 1 slice of ginger and a little cooking wine. Bring to a boil over high heat, skim off the foam, then remove and rinse thoroughly with warm water. This step is called “blanching,” which effectively removes any fishy odor and blood impurities.

Step 2: Stewing in a covered pot. Place the prepared lean meat into a stewing pot or earthenware pot. Add the rinsed American ginseng slices (Panax quinquefolium), red dates (Fructus Jujubae, pitted), and the remaining ginger slices (Rhizoma Zingiberis Officinalis). Pour in approximately 800 ml of boiling water (about 3 rice bowls’ worth). Cover with a lid and cook either by double-boiling (over water) or simmering directly over low heat.

Step 3: Control the heat and cooking time. For double-boiling (隔水炖法), once steam appears, reduce to medium-low heat and simmer for 1.5 hours. If boiling directly, bring to a vigorous boil over high heat, then reduce to low heat and simmer for 1 hour. Avoid frequently opening the lid during cooking to prevent loss of aroma. Sprinkle in goji berries (Lycium barbarum) 5 minutes before finishing, allowing them to steep in residual heat.

Step 4: Season and enjoy. Turn off the heat, skim off a small amount of surface oil, and add an appropriate amount of table salt (optional), stirring gently. Pour into a bowl and drink while warm. The American ginseng slices can be chewed and eaten, offering a sweet, cool, and aromatic aftertaste. If you prefer a richer flavor, you may tear the lean meat into small strips before eating.

Tips for Drinking

1. Optimal Consumption Timing: It is recommended to drink between meals or around 10 AM, when the Spleen (Pi) and Stomach (Wei) have stronger transformative and transportive capacity, maximizing absorption. Avoid large consumption before bedtime to prevent nocturia from disrupting sleep. Consume 2-3 times per week; do not take in large amounts consecutively.

2. Incompatible Ingredients: While consuming American Ginseng and Lean Meat Soup, one should avoid simultaneously eating radish, strong tea, and coffee. Radish can weaken the Qi-tonifying effect of ginseng-type herbs; tannic acid in strong tea and coffee may affect the absorption of saponins. Additionally, it is not advisable to use this soup together with Chinese herbs such as Veratrum nigrum (black false hellebore) and Faeces Trogopteri (Trogopterus dung).

3. Storage and reheating: If a larger amount is decocted at one time, the dregs can be separated from the liquid, and the liquid refrigerated for no more than 24 hours. When drinking again, it must be brought to a full boil. However, it is not recommended to repeatedly decoct Panax quinquefolius (American ginseng) slices, as the medicinal efficacy will noticeably decrease. It is best to prepare and drink it fresh, as freshness is optimal.

4. Constitution Adjustment Method: For different constitutions, minor modifications can be made to the base formula. If marked shortness of breath is present, add 5g of Astragalus membranaceus (Huangqi) to the decoction. If severe dry throat is present, add 5g of Ophiopogon japonicus (Maidong). If sleep is poor, add 10g of Longan aril (Longyanrou). However, only one ingredient should be added at a time to avoid overly complicating the formula and affecting the taste.
