Mugwort Tea: An Ancient Remedy Through the Lens of Modern Science
Mugwort has a long history as a medicinal herb. People used it for digestive and menstrual complaints centuries before it appeared in today’s herbal tea blends. But does drinking mugwort tea actually ease bloating, relieve cramps, or help you sleep?
Research in people has not established those benefits or identified a reliably safe dose for the tea. Avoid mugwort during pregnancy. If you’re considering it for a particular symptom, it helps to know which plant is in the packet and whether the research behind a claim involved anyone actually drinking it. NCCIH
What Is Mugwort Tea?
Mugwort tea is an herbal infusion usually made by steeping the dried leaves or other above-ground parts of common mugwort, Artemisia vulgaris, in hot water. Common mugwort is an aromatic perennial in the daisy family. Gardeners may recognize its deeply lobed leaves: green on top, with a pale, woolly underside. It spreads through underground stems and can become invasive in some regions. Those features help describe the plant, but they aren’t enough to identify a wild herb for drinking.

The most useful detail on a tea label is the botanical name. Common mugwort (Artemisia vulgaris), common wormwood (Artemisia absinthium), and sweet wormwood (Artemisia annua) are different species. To make matters more confusing, common mugwort itself is sometimes called “wild wormwood.” A shared nickname doesn’t mean the plants have the same effects or safety profile.

Why Did People Traditionally Use Mugwort?
Mugwort appears in European, Chinese, and Hindu medicinal traditions, particularly in accounts of care for digestive and gynecological complaints. In medieval Europe, it was known as the “mother of herbs,” a name that captures the esteem people once held for it. NCCIH
That history helps explain why someone might reach for mugwort after a meal or during a difficult period. It answers one question well: What did people use the herb for? A different question—did the tea relieve symptoms more reliably than they would have improved on their own?—requires studies in people. For mugwort tea, that evidence is still lacking. NCCIH
Does Mugwort Tea Help Digestion, Sleep, or Menstrual Cramps?
Digestion: Digestive discomfort is among mugwort’s best-documented traditional uses. Reliable human evidence has not shown that the tea relieves bloating or indigestion. If discomfort keeps returning after meals, a record of when it occurs is more useful to discuss with a healthcare professional than increasing the strength of a brew. NCCIH
Sleep and anxiety: Mugwort is promoted for insomnia and anxiety, but research has not established it as a treatment for either. Someone may enjoy the quiet routine of preparing a warm drink before bed; that experience alone can’t tell us whether mugwort changes sleep quality. NCCIH
Menstrual cramps: Historical use is not enough to recommend mugwort tea for period pain or to bring on a late period. The distinction matters especially if pregnancy is possible: skip the tea rather than using it to try to start bleeding. NCCIH
What Has Modern Research Actually Tested?
One preliminary human study often mentioned in discussions of mugwort examined itching in raised scars. Participants used a skin lotion containing both mugwort and menthol. They did not drink mugwort tea. Even for the lotion, researchers could not tell which ingredient accounted for the reported relief. NCCIH
That example offers a useful way to read an herbal health claim. Look for three details: Which species did the researchers study? What preparation did people use? What outcome did they measure? A result involving a lotion on a scar doesn’t answer whether a leaf infusion helps someone sleep.
Who Should Avoid Mugwort Tea?
- During pregnancy: Avoid mugwort, including tea. The US National Center for Complementary and Integrative Health explicitly advises against its use during pregnancy. NCCIH
- While breastfeeding: There is too little safety information to recommend drinking it. Ask your healthcare professional before using it. NCCIH
- If you have a known mugwort allergy: Avoid the tea. If you have mugwort pollen allergy or have reacted to herbal blends before, ask an allergist rather than testing your tolerance with a cup. Mugwort pollen is associated with cross-reactions to certain foods in some people. aaaai.org
- If you take medication: Ask a pharmacist or clinician to review the exact product, including any other herbs in the blend. Limited research means there isn’t a dependable list of mugwort tea interactions to check off at home. NCCIH
Frequently Asked Questions
Can you drink mugwort tea every day?
There is no well-established safe daily amount. A packet’s brewing directions describe how the seller intends the product to be prepared; they don’t establish that daily or long-term use is safe. NCCIH
Does mugwort tea cause vivid or lucid dreams?
There isn’t reliable human evidence that drinking mugwort tea consistently produces vivid dreams or lets people control them. Personal accounts can describe a memorable night, but they can’t establish what caused it or predict someone else’s experience. NCCIH
Is mugwort the same as wormwood?
Not necessarily. A product labeled Artemisia vulgaris contains common mugwort; Artemisia absinthium refers to common wormwood. Because their everyday names overlap, check the Latin name before relying on information about either plant. North Carolina Extension Gardener Plant Toolbox
Can I make tea from mugwort growing in my garden?
A garden plant with silvery leaf undersides isn’t automatically safe to harvest. Several Artemisia species share common names, and even a correct identification doesn’t resolve the uncertainty about drinking A. vulgaris. If you can’t verify what the plant is, leave it out of the cup. North Carolina Extension Gardener Plant Toolbox
