Ginseng root is one of the most recognized herbal ingredients in the world, and one of the most misrepresented. Walk into any supplement aisle or health food store and you will find ginseng in capsules, powders, extracts, energy drinks, and dozens of products that use the name without much respect for the plant behind it. But ginseng has a story that stretches back thousands of years — long before it became a label on a bottle. At its core, ginseng is a slow-growing root with a distinctive flavor and a central place in traditional herbalism across East Asia and North America. Brewed as a tea, it is something worth understanding properly.
At Valley of Tea, we have been sourcing and tasting teas for over fifteen years. This guide draws on that experience.
This guide covers what ginseng root actually is, how it tastes, how to brew it, how the major varieties differ, and what to look for when buying ginseng root for tea.
Ginseng refers to plants in the genus Panax, a small group of slow-growing perennials in the family Araliaceae. The name Panax comes from the Greek "panakes," meaning "all-healing" — a label that reflects the plant's status in traditional medicine rather than any modern medical claim. There are several species, but two dominate the conversation: Panax ginseng (Asian ginseng, also called Korean ginseng or Chinese ginseng) and Panax quinquefolius (American ginseng).
Both species share the same basic structure: a fleshy, forked root that vaguely resembles the human body (the Chinese character for ginseng, ren shen, literally means "person root"), compound leaves, and small red berries. The root is the part used in teas and traditional preparations. It takes four to six years of growth before a ginseng root is mature enough to harvest, which is a significant part of why quality ginseng has always been expensive.
A common source of confusion: many products labeled "ginseng" contain Siberian ginseng (Eleutherococcus senticosus), which is not a Panax species at all. It belongs to the same plant family but is a different genus entirely. If you are looking for true ginseng, the label should specify Panax ginseng or Panax quinquefolius.
Panax ginseng is native to the mountainous regions of northeastern China, Korea, and eastern Siberia. It is the original ginseng — the one that has been cultivated and traded in East Asia for millennia. In traditional Chinese medicine, Asian ginseng has been used as a tonic ingredient for centuries, often described in classical texts as a warming, stimulating root. Korean red ginseng, which is Panax ginseng that has been steamed and dried (a process that turns the root a deep reddish-brown), is among the most prized forms.
Wild Panax ginseng is extremely rare today due to centuries of overharvesting. Nearly all Asian ginseng on the market is cultivated, primarily in South Korea, China, and to a lesser extent Japan. The best cultivated roots are grown in mineral-rich mountain soils with careful shade management, mimicking the forest understory conditions the plant favors naturally.
American ginseng grows wild in the deciduous forests of eastern North America, from southern Quebec to Georgia. It was used by several Indigenous peoples long before European contact, and by the early 1700s it had entered the global trade — largely because Chinese merchants recognized it as a close relative of their own ginseng and valued it for its distinct properties. According to the USDA Plants Database, Panax quinquefolius is listed in Appendix II of CITES to control international trade and protect remaining wild populations. (USDA Plant Guide: American Ginseng.)
In traditional use, American ginseng is milder and cooler in character compared to the warming nature attributed to Asian ginseng. This distinction matters in traditional Chinese medicine, where the two are not considered interchangeable. American ginseng became so popular in the Chinese market that wild populations were decimated by the 19th century. Today, both wild-harvested and cultivated American ginseng are available, with wild roots commanding significantly higher prices. Wisconsin and Ontario are major cultivation regions.
Ginseng root tea is one of the simplest and oldest ways to use the root. In Korea, ginseng tea (insam-cha) is a staple — served hot, sometimes with honey or jujube dates, and consumed daily by many people as a matter of routine rather than remedy. In China, sliced ginseng root steeped in hot water is a common preparation that dates back centuries.
The tea can be made from fresh root, dried root, or powdered root, each producing a different experience. Fresh ginseng root tea has the brightest, most complex flavor. Dried ginseng produces a more concentrated, earthy cup. Powdered ginseng makes a quick but cloudier brew that lacks the nuance of sliced or whole root preparations.
Ginseng tea is naturally caffeine-free. It can be consumed at any time of day, though many traditional practitioners in East Asia recommend drinking it in the morning.
Ginseng root tea has a flavor profile that surprises most first-time drinkers. It is not a light, floral herbal tea. It has substance.
The dominant note is earthy — a deep, rooty earthiness comparable to burdock or astragalus, but with more complexity. Behind that earthiness sits a distinct bitterness, not sharp or tannic like black tea, but slow and lingering, settling into the back of the palate. And then, unexpectedly, there is sweetness. Not sugar-sweetness but a subtle, almost starchy sweetness that emerges as you drink, particularly in the aftertaste. Good ginseng root has a long finish — the flavor stays with you for minutes after the last sip.
The balance between these three elements — earthy, bitter, slightly sweet — depends on the type of ginseng and how it was processed. Asian red ginseng (steamed and dried) tends to be the most intense: deeper bitterness, stronger earthiness, and a more pronounced warming sensation. White ginseng (dried but not steamed) is milder. American ginseng is generally the gentlest of the three, with less bitterness and a cleaner, slightly cooler finish that some drinkers describe as refreshing.
Good ginseng root produces a tea with noticeable body — it feels thicker in the mouth than most herbal infusions. This is partly due to the ginsenosides and polysaccharides present in the root, which give the liquid a slight viscosity. A 2024 phytochemistry review published in Molecules (2019) confirmed that ginsenosides and polysaccharides are the primary active compounds in Panax roots and contribute significantly to their characteristic flavor and functional properties. (PMC: Phytochemistry and Quality Control in Ginseng Research 2021–2023.)
Brewing ginseng root tea is straightforward, but the method varies depending on the form of root you are using.
This is the most common form for tea brewing and produces the best cup.
For whole roots, the traditional Korean method is to simmer rather than steep. Place the whole root in a pot with 2–3 cups of water, bring to a gentle boil, then reduce heat and simmer for 30–60 minutes. This slow extraction pulls out more of the root's compounds and produces a richer, more full-bodied tea. The root can be reused for a second or even third simmering.
Use about 1 teaspoon of ginseng powder per cup. Add hot water and stir well. The tea will be cloudy and slightly gritty. Some drinkers strain it through a fine mesh. Powder is convenient but produces a less refined cup than sliced or whole root.
If you can get fresh ginseng root, slice it thinly and steep as you would dried slices, but use slightly less (3–4 slices per cup) since fresh root is more potent by weight. Fresh ginseng tea has a brighter, more aromatic quality that dried root cannot fully replicate.
The differences between Asian and American ginseng go beyond geography. They are distinct species with different chemical profiles and, importantly for tea drinkers, different flavors.
Asian ginseng (Panax ginseng) has traditionally been characterized as warming and stimulating. The flavor is bolder: more bitter, more earthy, with a noticeable heat that builds as you drink. Red ginseng — which is Asian ginseng that has been steamed — amplifies these qualities further. In traditional East Asian practice, Asian ginseng has been associated with energy and vitality, and is a common ingredient in traditional tonic preparations.
American ginseng (Panax quinquefolius) has traditionally been considered cooling and calming. The flavor is softer: less bitter, slightly sweeter, with a cleaner finish. It is generally more approachable for newcomers to ginseng tea. In traditional Chinese medicine, American ginseng was historically favored during warmer months or by individuals who preferred a gentler root. A PMC review on American ginseng's bioactive phytochemicals confirms the distinct ginsenoside profile of Panax quinquefolius compared to Panax ginseng, which underpins both its flavor and traditional character. (PMC: American Ginseng as a Source of Bioactive Phytochemicals.)
For tea purposes, I think of it as a three-way split. Korean ginseng (Panax ginseng from Korea, usually red) is the one to reach for when you want the full, uncompromised ginseng experience — very strong, bold bitterness, pronounced earthiness, and a warming finish that builds. It is the variety I recommend when someone tells me they want to actually taste ginseng. Chinese Panax ginseng and American ginseng both occupy a different register: less intensity, better suited to daily drinking without being an event in itself. All three brew well — the root holds up to repeated steeping — but Korean ginseng rewards patience the most in the cup.
Ginseng root pairs well with other ingredients and appears in numerous traditional and modern blends.
In Korean tradition, ginseng is often combined with jujube dates (daechu) and honey to create a balanced, naturally sweetened tea that tempers the root's bitterness. Ginger and ginseng is another classic pairing — the ginger adds spice and warmth while complementing the earthiness of the root.
In Chinese herbal tradition, ginseng frequently appears alongside ingredients like astragalus, licorice root, and goji berries in compound preparations. These are not flavor blends in the Western tea-blending sense — they are formulated according to traditional herbal principles.
Modern tea blenders have incorporated ginseng into a wide range of products. Ginseng and green tea is a popular combination, where the vegetal freshness of green tea balances the earthiness of the ginseng. For a traditional Japanese green tea with an earthy, roasted dimension that pairs well with bold herbal bases, our genmaicha is a good companion to explore. Ginseng oolong — a Taiwanese specialty where oolong tea leaves are coated with a ginseng and licorice powder — is widely available and offers an accessible entry point for drinkers curious about ginseng flavor without committing to a pure ginseng tea. Our milk oolong and traditional pouchong are both from Taiwan and illustrate the range of Taiwanese oolong styles that ginseng blenders draw from.
Ginseng also works well with mint (which brightens the earthy base), lemongrass (which adds citrus lift), and cinnamon (which complements the root's natural warmth). When blending at home, start with ginseng as the base and add smaller quantities of complementary ingredients until you find a ratio you enjoy.
The ginseng market is large, varied, and not always transparent. Knowing what to look for saves money and disappointment.
Whole dried ginseng roots are the premium option. You can see exactly what you are getting — the size, the color, the number of branch roots. Whole roots store longer and retain their flavor better than pre-cut forms. The downside is cost and convenience: whole roots are more expensive and need to be sliced before brewing.
Sliced ginseng root is the practical choice for daily tea drinking. Look for evenly cut slices with a clean, consistent color. Avoid slices that look dusty, overly pale, or that have an off smell. Good sliced ginseng should have a clean, slightly sweet, earthy aroma.
Ginseng powder is the most affordable and least traceable form. It is impossible to judge the quality of the root once it has been ground. Powder is fine for quick cups or for adding to smoothies, but for serious tea drinking, sliced or whole root is worth the extra cost.
Age matters. Ginseng roots are typically harvested at four to six years of growth. Older roots (six years) are superior — they have had more time to develop their characteristic compounds. Some premium Korean red ginseng is exclusively six-year root.
Color tells you about processing. White ginseng is pale, air-dried or sun-dried. Red ginseng is reddish-brown, steamed before drying. The color should be consistent — mottled or uneven coloring can indicate poor processing.
Look for roots or slices that are firm and dry, not soft or flexible. Properly dried ginseng should snap cleanly when bent. If it bends without breaking, the moisture content is too high, and the product will not store well.
Buy from reputable sources that specify the species (Panax ginseng or Panax quinquefolius), the origin, and ideally the age of the root. Organic certification is a reasonable quality signal, particularly for cultivated ginseng where pesticide use can be a concern. If you are exploring East Asian teas that pair naturally with ginseng, our Tie Guan Yin oolong and gunpowder green tea represent the traditional tea traditions from the same regions where ginseng cultivation has the deepest roots.
Proper storage keeps ginseng root viable for a long time. Dried ginseng root, stored correctly, can last two years or more without significant loss of flavor or aroma.
Keep dried ginseng in an airtight container, away from light, heat, and moisture. A glass jar with a tight seal works well. Avoid plastic bags, which can trap residual moisture and promote mold. Store in a cool, dark cupboard — not in the refrigerator, where condensation can be a problem unless the root is sealed in a truly airtight container.
Whole roots store better than sliced roots, and sliced roots store better than powder. If you buy whole root and slice it yourself as needed, you will get the longest shelf life and the freshest cup.
Fresh ginseng root should be wrapped in a damp paper towel, placed in a perforated bag, and stored in the refrigerator. It will keep for two to three weeks this way. For longer storage, fresh root can be frozen — wrap tightly in plastic wrap and then in a freezer bag. Frozen ginseng root is easy to slice thinly while still frozen, making it convenient for tea preparation.
If your dried ginseng develops any visible mold, off odors, or a soft texture, discard it. Ginseng is too valuable an ingredient to risk a compromised product.
Ginseng root is not a trend ingredient or a novelty. It is a plant with thousands of years of continuous use across multiple cultures, a genuinely interesting and complex flavor, and a place in the tea world that is entirely its own. Whether you start with the bold intensity of Korean red ginseng or the milder character of American ginseng, the root rewards patience — both in the years it takes to grow and in the slow, meditative process of brewing and drinking it properly.
