Making ginseng tea from dried roots is straightforward: use 4 to 5 grams of dried root per 8-ounce cup of water, simmer just below boiling, and steep for 10 to 20 minutes. That’s the core method, but the details matter if you want to get the most flavor and beneficial compounds out of your roots.
What You Need
For a single cup of ginseng tea, measure out 4 to 5 grams of dried ginseng root. That’s roughly 3 to 5 thin slices or a small handful of root prongs, depending on how your ginseng was cut. You’ll also need 8 ounces of filtered water and a small saucepan or pot with a lid. A kitchen scale helps with precision, but after a few cups you’ll be able to eyeball it.
If your dried roots are whole rather than pre-sliced, cut them into thin slices or small pieces before brewing. Thinner slices expose more surface area to the water, which pulls out more of the active compounds. A sharp knife works, though dried ginseng can be tough. Soaking the root in warm water for 10 to 15 minutes beforehand softens it enough to slice easily.
Step-by-Step Brewing Method
Bring your water to about 200°F (93°C), which is just below a full rolling boil. You’ll see small bubbles forming on the bottom of the pot and steam rising, but the water shouldn’t be churning. If you don’t have a thermometer, bring the water to a boil and then let it sit for 30 seconds to a minute before adding your ginseng.
Add the sliced root directly to the water and reduce the heat to maintain a gentle simmer. Cover the pot and let it steep for 10 to 20 minutes. A 10-minute steep produces a milder, slightly sweet tea. Going the full 20 minutes gives you a stronger, more bitter brew with a deeper earthy flavor. Taste at 10 minutes and decide whether you want to keep going.
Strain the liquid into a cup, and your tea is ready. The slices can be reused for a second or even third brewing. Each successive steep will be lighter, so you can extend the simmer time by a few minutes to compensate.
Why Temperature Matters
Ginseng’s key beneficial compounds, called ginsenosides, are sensitive to heat. Research on red ginseng extraction found that water at around 190°F (90°C) for up to 60 minutes produced the highest ginsenoside content and antioxidant activity. But pushing beyond that, with higher temperatures or longer extraction times, actually degraded those compounds and reduced antioxidant levels. In practical terms, this means a gentle simmer is better than a hard boil. Keeping the water just below boiling protects the compounds you’re trying to extract while still pulling them out efficiently.
Red Ginseng vs. White Ginseng
Dried ginseng comes in two main forms, and the difference matters for your tea. White ginseng is simply fresh ginseng that has been sun-dried. Red ginseng goes through an additional steaming step before drying, which reduces its moisture content to less than 15% and chemically transforms its ginsenoside profile. The steaming process creates new compounds not found in white ginseng, and research consistently shows red ginseng has stronger biological activity.
Both types brew well using the same method. Red ginseng tends to produce a richer, slightly sweeter tea with a darker color. White ginseng yields a lighter, more delicate flavor. Neither requires a different water temperature or steaming time, though some people prefer to simmer red ginseng for closer to 20 minutes to fully extract its deeper flavor profile.
Choosing Good Dried Roots
Quality in dried ginseng depends on the species, where it was grown, how old the root was at harvest, and its physical shape. In traditional markets, ginseng is still graded primarily by visual inspection. Older roots (typically 4 to 6 years at harvest) are considered more potent and command higher prices.
When shopping, look for roots that are firm, intact, and free of soft spots or visible mold. The surface should be dry with no oily residue. Whole roots with visible ring markings (horizontal lines circling the upper neck of the root) indicate age. More rings generally mean an older, more mature plant. Roots that have been pre-sliced should look clean and uniform, without dark discoloration that might signal improper drying or storage.
Variations Worth Trying
Plain ginseng tea has a distinctive earthy, slightly bitter flavor that not everyone loves right away. A few additions can make it more approachable without interfering with the ginseng itself.
- Honey and ginger: Add a few slices of fresh ginger to the pot while simmering, then stir in honey after straining. The ginger adds warmth and the honey rounds out the bitterness.
- Jujube dates: A traditional Korean pairing. Toss 2 or 3 dried jujubes into the pot with the ginseng. They add natural sweetness and a slightly fruity depth.
- Cinnamon stick: One small stick simmered alongside the ginseng gives the tea a warming, spiced quality that pairs naturally with the root’s earthiness.
- Cold brew: Place sliced dried ginseng in a jar of cold water and refrigerate overnight (8 to 12 hours). This produces a milder, smoother tea that works well in warm weather.
How Much to Drink
Most clinical research on ginseng has used between 0.5 and 3 grams of dried root per day. The German Commission E, a widely referenced authority on herbal preparations, recommends 1 to 2 grams of dried root daily for up to 3 months, followed by a break. At 4 to 5 grams per cup, a single cup of tea already exceeds that conservative guideline, so one cup a day is a reasonable starting point. Some people brew a lighter cup using 2 to 3 grams instead.
Cycling on and off is a common practice among regular ginseng drinkers. A typical pattern is daily use for 2 to 3 months, then a few weeks off before starting again.
Who Should Be Cautious
Ginseng tea is safe for most adults, but there are a few notable exceptions. Asian ginseng (Panax ginseng) may lower blood sugar levels, which can be a problem if you’re managing diabetes with medication, since the combined effect could push blood sugar too low. It may also interfere with blood clotting, making it a concern for people taking blood-thinning medications.
There are also potential interactions with certain blood pressure medications, statins, and some antidepressants, though the evidence is less clear-cut. Ginseng is not recommended during pregnancy; one of its chemical components has caused birth defects in animal studies. It’s also generally advised against for infants and young children. People with autoimmune conditions should be cautious, as ginseng may stimulate immune activity in ways that worsen those conditions.
Storing Your Dried Roots
Dried ginseng roots keep well when stored in a cool, dry, well-ventilated space. Moisture is the primary enemy: it encourages mold growth and degrades the root over time. Keep roots in an airtight container with a desiccant packet if your environment is humid. A pantry or cupboard away from the stove works well. Avoid refrigerating dried roots, as opening and closing a cold container introduces condensation. Properly stored dried ginseng can last a year or more without significant loss of quality.
