rénshēn piàn

Ginseng slices (人参片, rénshēn piàn) are thinly cut and dried roots of true ginseng (Panax ginseng), which in China are steeped in hot water and drunk as an infusion, as well as added to tonic soups. Let us clarify at once: this is not tea in the botanical sense — there is no leaf of the Chinese camellia (Camellia sinensis) here at all, and the beverage itself belongs to the category of “substitute teas,” or herbal infusions (代用茶, dàiyòng chá). The main raw material is harvested in the northeast of the country, in the Changbai Mountains (长白山, Chángbáishān) of Jilin Province (吉林, Jílín). In daily life, the slices are brewed in a thermos or a glass cup, added to decoctions and tinctures, and the root itself has remained a symbol of health and longevity in Chinese culture for millennia. On the market, two main types are distinguished — aged red (老红人参片, lǎo hóng rénshēn piàn) and white (白人参片, bái rénshēn piàn), which differ in processing method. The product must be strictly separated from “ginseng oolong” (人参乌龙, rénshēn wūlóng): there the base is camellia leaf flavored with extract, whereas here only the root itself is brewed.

1. Classification and Origin:

• Type: herbal infusion from dried root, tea substitute (代用茶, dàiyòng chá).
• Botanical species: true ginseng (Panax ginseng C. A. Meyer), family Araliaceae.
• Part used: mainly the root with the rhizome “neck.”
• Main forms: red ginseng (红参, hóngshēn) and white ginseng (白参, báishēn), also known as “sun-dried raw” (生晒参, shēngshàishēn).
• Origin of raw material: northeast China, primarily Jilin; also Liaoning (辽宁, Liáoníng) and Heilongjiang (黑龙江, Hēilóngjiāng).

It is important to be precise here: there is no Chinese camellia in the product, so it is not “tea” in the strict sense. In the Chinese commodity system, such beverages are classified as 代用茶 (dàiyòng chá) — that is, infusions of plant raw materials brewed “instead of tea.” At the same time, the product has its own centuries-old tradition, its own terroir, and its own technology, and it is incorrect to regard it as a “surrogate” — it is an independent genre. We note separately that a closely related by name but different species — American ginseng (西洋参, xīyángshēn, Panax quinquefolius) — is sold as a separate raw material and is not identical to Panax ginseng.

2. History and Cultural Significance:

• Antiquity: ginseng has appeared in Chinese tradition for over two thousand years; it is mentioned in the classical herbal “Shennong Bencao Jing” (神农本草经, Shénnóng Běncǎo Jīng) as a substance of the highest category.
• Historical geography: in ancient times, “Shangdang” ginseng (上党, Shàngdǎng, present-day southeastern Shanxi) was especially prized; after the depletion of the thickets there, the center of harvesting shifted to the northeast — to “Guandong” (关东, Guāndōng).
• Qing Dynasty: the Manchu rulers considered Changbaishan their ancestral territory and introduced a permit system for collecting wild roots (参票, shēnpiào), restricting the trade.

Ginseng is part of the well-known triad of the “Three Treasures of the Northeast” (东北三宝, dōngběi sān bǎo) along with sable fur and (in different versions of the saying) sedge grass or antler velvet. The root was traditionally given as a sign of respect and a wish for robust health, and used in festive tonic soups. We note that regarding the historical “Shangdang” ginseng, there is no consensus among researchers: some authors believe that this name may have referred to a different plant — bellflower root (党参, dǎngshēn, Codonopsis pilosula); the question remains debatable.

3. Botanical Description and Raw Material:

• Life form: perennial herbaceous plant approximately 30–60 cm in height.
• Leaves: palmately compound, arranged in a whorl at the top of the stem.
• Flowers and fruits: small greenish-yellow flowers in an umbel; fruits are bright red berry-like drupes.
• Root: fleshy, often with lateral branches and fine rootlets; the shape frequently resembles a human figure, hence the name 人参 (rénshēn) — literally “man-root.”
• Age of raw material: plantation root is usually dug up in the 4th to 6th year; wild specimens grow for decades.

The genus name Panax goes back to the Greek “panakeia” — “all-healing,” that is, the same root as the word “panacea.” Commercial value is determined by the size, integrity, and shape of the root, and for cut slices — the thickness and uniformity of the slices.

4. Terroir and Cultivation Features:

• Range: cool forested slopes of Changbaishan and adjacent mountains of the Northeast.
• Soil and light: humus-rich, well-drained, slightly acidic soils; the plant requires shade, so plantations are covered with canopies or grown under the forest canopy.
• Types of origin: plantation ginseng (园参, yuánshēn); wild mountain ginseng (山参, shānshēn); “under-forest” semi-wild ginseng (林下参, línxiàshēn); and “transplanted mountain” ginseng (移山参, yíshānshēn).
• Key areas: Fusong County (抚松县, Fǔsōng xiàn) in Jilin, known as the “land of ginseng”; as well as neighboring counties of the province.

Ginseng is extremely sensitive to “soil fatigue”: it cannot be replanted on the same plot for many consecutive years, which forces constant exploitation of new plots. The difference between 园参 and 山参 is fundamental both for price and for organoleptics: plantation root is larger and “milder” in taste, while wild root is smaller, denser, with a more pronounced aroma and orders of magnitude more expensive.

5. Production Technology:

• Harvesting: roots are dug up in autumn, cleaned of soil, and sorted.
• White ginseng (生晒参): washed roots (sometimes with the skin removed) are dried in the sun or in a stream of warm air; the color remains light — from creamy-yellow to pale brownish.
• Red ginseng (红参): selected fresh roots are steamed for several hours, then dried; under the action of heat, the tissue becomes semi-transparent, vitreous, and the color turns dark amber to reddish-brown.
• Slicing: the dried root is cut into thin slices (切片, qiēpiàn) — this is the form 人参片.
• Sorting: by size, shape, and integrity.

Steaming not only changes the color and density but also improves shelf life: red ginseng stores longer and is less susceptible to spoilage than white ginseng. The label “aged red” (老红, lǎo hóng) usually indicates more mature or higher-grade raw material.

6. Organoleptic Characteristics:

• Red slices: reddish-brown to dark amber, semi-transparent and vitreous, hard; aroma warm, resinous-sweetish; taste bitter with a pronounced sweet aftertaste (回甘, huígān).
• White slices: yellowish-white to pale brownish, less transparent; aroma fresher, “herbaceous-rooty”; taste milder, bitterness weaker.
• Infusion: from light yellow to amber, clear; in taste — a light bitterness and a sweet “return.”

7. Chemical Composition:

• Ginsenosides (人参皂苷, rénshēn zàogān): triterpene saponins — a group of compounds characteristic of the genus; several dozen have been identified (Rb1, Rg1, Re, Rd, and others).
• Steaming products: during the processing of red ginseng, rarer ginsenosides are formed (for example, Rg3, Rh1, Rh2), which are almost absent in the fresh root.
• Ginseng polysaccharides: a separate group under study.
• Other: amino acids and peptides, polyacetylenes, essential oils, sterols, as well as vitamins and minerals.

The composition depends noticeably on the type (red or white), origin (plantation or wild), age of the root, and processing method, so no single “reference” figures for the content of active substances exist.

8. Beneficial Properties:

• What is traditionally believed: in Chinese everyday and medical culture, ginseng is considered a classic “strongly supplementing the original qi” agent, associated with restoring strength and general tone; in the folk system, it belongs to the highest category of tonic raw materials.
• What science studies: modern research focuses on ginsenosides and polysaccharides; ginseng is often described in the literature as an “adaptogen,” however this is a research characterization, not a proven medical indication.

It must be stated directly: ginseng slices are a food product, not a medicine, and no therapeutic promises may be made; retail health claims go beyond the scope of an encyclopedia. Among the generally known precautions, we neutrally name moderation in consumption; caution during pregnancy and breastfeeding; possible interaction with a number of medications, including anticoagulants; and the fact that with elevated blood pressure, excitability, or insomnia, the reaction may be individual. In ambiguous situations, consultation with a specialist is appropriate; specific dosages and recommendations are not given here.

9. Brewing:

• Ratio: approximately 3–5 g of slices (2–4 pieces) per 200–300 ml of water.
• Water: hot, 90–100 °C — the dense root needs high temperature.
• Vessels: glass cup, gaiwan, thermos, or small teapot; simmering over low heat is also acceptable.
• Time and infusions: first infusion — several minutes; the root withstands many infusions, often 5–10.

A convenient household method is “thermos steeping” (焖泡, mènpào): the slices are covered with boiling water, closed, and left for 15–30 minutes or longer, topping up with water throughout the day. For a richer infusion, the root is simmered for 20–40 minutes. The softened slices after brewing are often chewed. In home tradition, ginseng is frequently combined with goji berries, red dates, or honey — this is a matter of taste, not therapeutic effect. The infusion is usually drunk hot; a chilled version is possible, but serving cold is atypical for this raw material. For people sensitive to the tonic effect, it is sensible to avoid a strong infusion late in the evening.

10. Storage:

• Conditions: dry, cool, dark place in a tightly closed container.
• Main enemies: moisture, mold, and insects — ginseng is susceptible to them.
• Long-term storage: slices are often kept in a refrigerator or freezer; red ginseng, thanks to steaming, stores better than white.
• Monitoring: periodically check for dampness, loss of aroma, and traces of pests.

With proper storage, the cut slices retain quality for an estimated 2–3 years; the appearance of mustiness, clumping, or wormholes is a reason to discard the raw material.

11. Price and Counterfeits:

• Price range: plantation cut slices (园参) — on the order of hundreds of yuan per kilogram; aged high-grade red is more expensive; wild mountain ginseng (山参) costs incomparably more and is sold per piece or by the gram.
• Spread: the supplier’s guide for this item is not fixed — the price strongly depends on the type, age, origin, and integrity of the root.

What to look for in genuine raw material: for red ginseng — semi-transparent vitreous structure, density, uniform reddish-brown color, and characteristic warm aroma; for white — correct root shape, fine ring wrinkles, and a fresh rooty smell. A whole wild root is evaluated by the “five features” (五形, wǔ xíng): the rhizome “neck” with bowl-shaped scars (芦碗, lú wǎn), dense spiral wrinkles at the “shoulder,” body shape, texture of the skin, and fine rootlets with “pearl” bumps. In slices, these features are lost, so wild ginseng is purchased as a whole root for authenticity.

Typical methods of substitution: passing off plantation root as wild; substitution with other roots — balloon flower (桔梗, jiégěng), as well as the knowingly toxic pokeweed (商陆, shānglù) and “Huashan” root (华山参, huàshānshēn); misgrading with American ginseng; “weighting” with sugar (糖参, tángshēn); and selling root from which ginsenosides have already been extracted. Suspiciously cheap “wild” ginseng almost always indicates falsification, so it is safer to buy from trusted suppliers.

12. Interesting Facts:

• Name-image: the characters 人参 (rénshēn) literally mean “man-root” — because of the root’s resemblance to a human figure.
• Panacea in the name: the generic name Panax is etymologically connected with the word “panacea.”
• Living tradition: the customs of ginseng gathering in Changbaishan (长白山采参习俗) were included in the list of China’s national intangible cultural heritage in 2008.
• Trade culture: the traditional search for wild root (放山, fàngshān) is accompanied by its own language, omens, and rituals — for example, tying the found plant with a red thread.
• Ginseng capital: Fusong County is officially positioned as the “land of ginseng” of China.
• Food status: in 2012, cultivated ginseng up to five years of age was included in the list of novel food raw materials of China, which legally opened its use in food products and beverages.
• Dual status: at the same time, ginseng remains an official raw material of the Chinese Pharmacopoeia (中国药典, Zhōngguó Yàodiǎn).
• Korean relative: the famous Korean ginseng (高丽参, gāolíshēn) belongs to the same species Panax ginseng.

In conclusion:

Ginseng slices are a characteristic representative of the 代用茶 (dàiyòng chá) genre: they are brewed and drunk “like tea,” but they are not tea, as they are made not from camellia leaf but from the root of Panax ginseng. Behind this simple-looking product stands an entire culture — the terroir of Changbaishan, the distinction between red and white root, plantation and wild ginseng, the harvesting customs of the Northeast, and the centuries-old role of the root as a sign of health and respect.

One should approach it calmly and without magical expectations: it is a valuable food product with its own taste, aroma, and brewing method, not a medicine. A reasonable choice of verified raw material, attention to signs of counterfeiting, and moderation in consumption — this is all that is needed to appreciate this infusion in its genuine quality, separating facts from retail promises.
