Dandelion root tea is searched about 33,100 times a month in the US, yet no published trial has tested the tea itself in people. The 2 human studies on the plant used a leaf extract and capsules of root powder.
That does not make the tea pointless. Roasted, it is one of the better caffeine-free coffee substitutes, and that is how this page treats it.

What Is in the Cup
Dandelion root tea is the dried taproot steeped or simmered in hot water. Unroasted, it is pale and earthy; roasted, it turns dark and bitter-sweet, close enough to coffee that it is sold as dandelion coffee. Many boxes are blends, so read the ingredients before assuming it is pure.
- The plant: Taraxacum officinale root, not the leaf.
- Caffeine: none, unless the blend adds black tea, green tea or coffee.
- Roasted or raw: roasting deepens flavour; no study shows it changes the effect.
- What we sell: no single-herb dandelion tea; our Ultimate Detox Tea blend includes roasted root.
For the plant behind the cup and how little of its research involves people, start with the overview.
How to Make Dandelion Root Tea
Root is tougher than leaf, so it gives more when simmered than when simply steeped. Europe's 2009 monograph lists 3 to 4 g of root with herb as a decoction, up to 3 times a day, as the traditional amount.[1]Dandelion Root with Herb, Traditional Use Monograph — European Medicines Agency View source
- Weigh 3 to 4 g of dried, chopped root; a kitchen scale beats guessing by the spoon.
- Add it to about 250 mL of cold water in a small pan.
- Bring to a simmer and keep it there for about 10 minutes.
- Strain, and soften the bitterness with a little milk or honey if you like.
Tea bags are milder because they hold less root and are steeped rather than simmered. Steep them covered for 5 to 10 minutes.
How to Make Dandelion Coffee
Dandelion coffee is roasted root, ground and brewed like coffee. It has no caffeine and a roasted, slightly bitter taste, and it will not give the lift coffee gives, which is the point for people cutting back on caffeine.
- Start with roasted root granules, or roast dried chopped root in a low oven until dark brown.
- Use about 1 tablespoon per 250 mL cup.
- Brew in a French press, or simmer for 10 minutes, then strain.
- Add milk if you like; it suits the roasted flavour.
Chicory is a different root from the same daisy family, and many dandelion coffees blend the 2. Both contain inulin, a fibre, and a 2006 analysis found dandelion root's inulin mostly short-chain.[2]Separation and quantification of inulin in selected artichoke cultivars and dandelion roots — Biomedical Chromatography (2006) View source
What the Human Studies Found
No trial has tested dandelion root tea, so the honest evidence for the cup is borrowed. The 2 human studies of dandelion on its own used other forms, they measured urine rather than digestion, and they disagree with each other.
| Study | What people took | What it found |
|---|---|---|
| 2009, 17 volunteers | 8 mL of fresh-leaf extract, 3 times in 1 day | More frequent urination after the first dose |
| 2026, 14 active adults | About 2.1 g of root powder in 4 capsules, with 1 L of water | No significant extra urine over 4 hours |
| Dandelion root tea or capsules over weeks | Not tested | No data |
The root study is the closer match to a strong cup of root tea, and it found nothing beyond the water itself.[3]Co-Ingestion of a Commercially Available Dandelion Root Powder Elicited No Additional Diuretic Effect Over 4 Hr Compared to Ingestion of Water Alone — International Journal of Sport Nutrition and Exercise Metabolism (2026) View source
A cup of tea is also not the lab extract behind the laboratory cancer findings, so cancer headlines say nothing about a daily cup.
Morning or Night, and How Many Cups
Because it has no caffeine, dandelion root tea can be drunk at any time of day. The only timing issue is the leaf: if your blend contains dandelion leaf, an evening cup may wake you at night to urinate, since the leaf is the part with diuretic data.
- Morning: a reasonable coffee swap with no caffeine.
- Evening: fine for pure root; leaf blends may mean night-time urination.
- Daily amount: the traditional ceiling is 3 cups made with 3 to 4 g each.
- Long term: Europe advises seeing a doctor if symptoms persist beyond 2 weeks.
If you would rather know the exact amount, compare the capsule and tincture doses before switching forms.
Who Should Skip the Tea
Tea feels gentler than a capsule, but it is the same root, and a strong habit can deliver more of it. MSKCC describes a 2013 case of finger necrosis in a 56-year-old man with chronic kidney disease who drank 10 to 15 cups a day for 6 months.[4]Dandelion, About Herbs — Memorial Sloan Kettering Cancer Center View source
- Daisy-family allergy: 18 of 20 such patients reacted to Asteraceae teas in a 2006 patch-test study.[5]Contact allergy to herbal teas derived from Asteraceae plants — Contact Dermatitis (2006) View source
- Gallstones or bile duct problems: listed as contraindications in Europe.
- Kidney disease: Europe flags a risk of high potassium.
- Lithium or diuretics: the effects could add up.
Pregnancy and breastfeeding are on the same list, because safety has not been established.
If You Want It Without Brewing
We do not sell a single-herb dandelion tea. We sell the root as a capsule and as a tincture, plus a detox tea blend that includes roasted root, which suits people who want dandelion on busy days or while travelling.
- Capsule: 1,000 mg of dried root, 60 per bottle, no taste.
- Tincture: a 1:2 root extract in water and alcohol, 2 fl oz.
- Detox tea: a blend, so count it if you also take a capsule.
- Pick 1: so you know your daily total.
If a capsule suits you better, the capsule form of the same root holds a measured 1,000 mg.
Speak to a Clinician Before Drinking Dandelion Root Tea Daily If

- You have gallstones, a blocked bile duct, cholangitis or liver disease
- You take lithium, a prescription diuretic, or a medicine that raises potassium
- You have kidney failure, heart failure or diabetes, where Europe flags a potassium risk
- You are pregnant or breastfeeding, where safety has not been established
Frequently Asked Questions
Is it okay to drink dandelion tea every day? +
For most healthy adults, a cup or 2 of root tea is food-level use. Europe's traditional ceiling is 3 cups made with 3 to 4 g each, and symptoms lasting over 2 weeks need a doctor.
Should you drink dandelion tea in the morning or at night? +
Either. Pure root tea has 0 caffeine. Blends that contain the leaf may increase urination, so drink those earlier in the day.
How long does it take for dandelion tea to work? +
For water, the 2009 leaf trial saw more frequent urination within 5 hours of the first dose. For digestion there is no timed human data at all.
Is dandelion coffee good for you? +
Its clearest benefit is what it removes: caffeine. 0 trials have tested dandelion coffee for any health outcome, so treat it as a pleasant swap rather than a remedy.
What does dandelion coffee taste like? +
Roasted, earthy and slightly bitter, closer to chicory coffee than to espresso. It has 0 caffeine, so it will not give coffee's lift.
How much caffeine is in dandelion coffee? +
None, if it is pure roasted dandelion root. Check the label, because 1 common style blends it with real coffee or black tea.
Why do I feel weird after drinking dandelion root tea? +
Possible reasons include stomach upset or acidity, listed in Europe's 2009 monograph, an allergy if you react to ragweed, or low blood sugar with diabetes medicine. Stop and get advice if it recurs.
What is the best dandelion root tea? +
Look for 1 ingredient, Taraxacum officinale root, roasted if you want the coffee flavour. Avoid roots dug from roadsides or lawns that may have been sprayed.
Does roasting change the benefits? +
No study has compared roasted with unroasted root in people. Roasting changes flavour and colour; with 0 trials of either, the choice is about taste.
Can I drink dandelion root tea while pregnant? +
It is not recommended. Europe's 2009 monograph says safety in pregnancy and breastfeeding has not been established.
