What is lavender tea good for?

Lavandula angustifolia (English lavender) flower buds, dried, culinary grade

Lavender tea is good for easing anxiety, settling into sleep and lifting a low or tired mood, and it is one of the few herbal teas whose active compound, linalool, has been tested in large randomized trials. The catch is that nearly all of that evidence comes from a standardized oral lavender oil capsule (80 to 160 mg of Silexan), not from the tea. A cup of lavender tea delivers a much smaller and more variable dose, so its effects are gentler and less certain.

The one trial of the tea itself is encouraging. In 80 sleep-disturbed postnatal women in Taiwan, drinking a cup of lavender tea daily for two weeks reduced fatigue and depression scores and improved bonding with their babies compared with controls, although the benefit faded two weeks after stopping. For anxiety, the oral oil matched lorazepam in one trial and paroxetine in another, and a 2019 meta-analysis of 65 studies found consistent reductions in anxiety across oral, inhaled and massage forms.

Lavender is pleasant, caffeine-free and well tolerated, with two real cautions: it adds to the drowsiness of sedatives, and lavender products have weak hormone-like activity that has been linked to breast growth in children exposed to the oil. Here is what the evidence supports, how to brew a cup that tastes of flowers rather than soap, and who should limit it.

What lavender tea is good for

  • Anxiety — oral lavender oil (80 mg daily) matched lorazepam over 6 weeks and paroxetine over 10 weeks; a 2019 meta-analysis found moderate anxiety reductions across forms
  • Low mood and fatigue — a cup of lavender tea daily for 2 weeks cut fatigue and depression scores in 80 sleep-disturbed new mothers
  • Sleep — inhaled lavender plus sleep hygiene improved sleep quality in 79 students; the oral oil improves sleep as anxiety eases
  • Headache — inhaling lavender oil for 15 minutes relieved 71% of migraine attacks vs 47% with placebo; untested as tea
  • Digestion — a traditional calming carminative; no trials

Lavender tea benefits, graded by the evidence

Strong = multiple human trials or a meta-analysis. Moderate = a few small trials. Preliminary = early, traditional or animal data.

  1. Calms anxiety

    Moderate evidence

    The strongest data are for a standardized oral lavender oil. In 77 adults with generalized anxiety disorder, 80 mg daily for six weeks lowered Hamilton Anxiety scores by 11.3 points, equal to lorazepam 0.5 mg. In a 539-patient trial, 160 mg and 80 mg both beat placebo over ten weeks and performed at least as well as paroxetine 20 mg. A 2019 meta-analysis pooling 65 trials of oral, inhaled and massage lavender found a moderate overall reduction in anxiety. Lavender tea contains the same linalool and linalyl acetate but at a fraction of the dose, so grade the tea itself as Moderate rather than Strong.

  2. Lifts low mood and fatigue

    Moderate evidence

    This is the one benefit tested with actual tea. Eighty postnatal women with poor sleep were assigned to drink one cup of lavender tea daily, spending time smelling it before drinking, or to usual care for two weeks. The tea group had significantly lower fatigue and depression scores and better maternal-infant attachment at two weeks; the difference was no longer significant two weeks after they stopped. Oral lavender oil has also reduced depressive symptoms alongside anxiety in people with mixed anxiety and depression.

  3. Improves sleep quality

    Moderate evidence

    Lavender helps sleep mainly by reducing the arousal that keeps people awake. In 79 college students with sleep problems, inhaled lavender plus sleep hygiene improved sleep quality more than sleep hygiene alone over five nights, with the benefit persisting at two weeks. In the oral oil trials, sleep improved in step with anxiety without any direct sedative effect, and a small crossover study found lavender aroma increased slow-wave sleep. No trial has measured sleep with lavender tea, but a warm, aromatic cup an hour before bed combines the inhaled and oral routes.

  4. Eases tension headaches and migraine

    Preliminary evidence

    In a placebo-controlled trial, 47 people with migraine inhaled lavender oil for 15 minutes at the onset of attacks. Of 129 attacks treated with lavender, 92 (71%) improved partly or fully, compared with 32 of 68 (47%) with placebo. The route was inhalation, not drinking, and the study was small. Drinking lavender tea gives some of the same aroma exposure, and the relaxation may help tension-type headaches, but that has not been tested.

  5. Settles the stomach

    Preliminary evidence

    Lavender was used in European herbal medicine for nervous indigestion, wind and loss of appetite, and the German Commission E approved the flowers for functional abdominal complaints. Linalool relaxes smooth muscle and reduces gut motility in animal studies, consistent with a mild antispasmodic effect. There are no human trials of lavender for digestion, and its benefit is probably tied to its calming effect on a stressed gut.

  6. Antioxidant and antimicrobial polyphenols

    Preliminary evidence

    Lavender flowers contain rosmarinic acid, apigenin and luteolin as well as the volatile oils, and infusions show antioxidant and anti-inflammatory activity in cell studies. Lavender oil is antimicrobial in culture against several bacteria and fungi, which supports its topical use. None of this has been tested as a drink in people, and the amounts in a cup are modest.

Is lavender tea good for you?

  • Yes, for most adults: one or two cups of lavender tea is a safe, caffeine-free way to unwind in the evening, and the ingredient it delivers has solid trial evidence for anxiety when taken as a standardized oil.
  • The tea is gentler and less predictable than the capsule; if you need a reliable effect for clinical anxiety, the trials used 80 to 160 mg of oral lavender oil, not tea.
  • Limit it if you take sedatives, sleeping pills, opioids or drink alcohol in the evening, since the drowsiness adds up.
  • Children, and families with a history of hormone-sensitive conditions, should go easy: lavender products have weak estrogen-like activity and have been linked to breast development in boys and girls exposed to the oil.
  • Never drink lavender essential oil; a few drops can cause nausea, vomiting and confusion. Use food-grade dried buds.

How to brew lavender tea

Amount

1 to 1.5 teaspoons (1 to 2 g) dried culinary lavender buds, or 1 bag, per 8 oz (240 ml)

Water

200°F / 93°C, a minute off the boil

Steep

3 to 5 minutes, covered; no longer

  • Over-steeping or using too many buds is what makes lavender taste like soap; start with 1 teaspoon and 3 minutes.
  • Buy culinary-grade Lavandula angustifolia; craft or potpourri lavender may be sprayed or be a harsher species.
  • It blends well with chamomile, lemon balm or a little honey, which round off the floral edge.

How much per day

One to two cups a day, with the second an hour before bed, is plenty. That delivers a modest amount of linalool, well below the standardized oil doses used in trials, and avoids the drowsiness and headache some people report with higher intakes.

Caffeine-free. Floral and slightly sweet when brewed lightly; soapy and bitter if over-steeped.

Side effects, interactions and who should limit it

Side effects

  • Drowsiness, especially combined with alcohol or sedatives
  • Headache or nausea with strong brews or large amounts
  • Constipation and belching, reported with the oral oil capsules
  • Skin reactions in people sensitized to lavender (usually from topical products)
  • Weak hormone-like activity: breast development reported in children using lavender oil products

Interactions

  • Benzodiazepines, Z-drugs, barbiturates and opioids: additive sedation
  • Alcohol and sedating antihistamines (diphenhydramine): additive drowsiness
  • Blood pressure medication: lavender aromatherapy has modestly lowered blood pressure and heart rate; watch for light-headedness
  • Anesthesia: stop lavender products two weeks before surgery because of the sedative effect

Pregnancy and breastfeeding

There is no safety data on regular lavender tea in pregnancy, and some herbal authorities advise avoiding it in the first trimester as a precaution; an occasional cup later in pregnancy is unlikely to cause problems, but do not take lavender oil by mouth. The lavender tea trial was done in breastfeeding women two to four weeks after birth with no reported harm to infants.

Frequently asked questions

Does lavender tea make you sleepy?

It is calming rather than sedating. In the oral oil trials, people slept better because their anxiety fell, not because lavender knocked them out, and the tea delivers a smaller dose again. Most people find it helps them wind down an hour before bed without grogginess the next morning.

Is lavender tea good for anxiety?

The active compound, linalool, has strong trial evidence for anxiety when taken as a standardized oral oil at 80 to 160 mg a day, where it matched lorazepam and paroxetine. The tea gives a lower and variable dose, so expect a gentle calming effect rather than treatment for an anxiety disorder. If you need more, the capsule form is the one that has been tested.

Can I drink lavender tea every day?

Yes, one or two cups a day is considered safe for healthy adults, and the two-week tea trial reported no adverse effects. Keep the brew light, use culinary buds, and skip it on evenings when you have taken sedatives or had a few drinks.

Why does my lavender tea taste like soap?

Too many buds or too long a steep. Lavender oils are potent, and above about a teaspoon per cup or four to five minutes they turn perfumed and bitter. Use 1 teaspoon, water just off the boil, and three minutes, and blend with chamomile if it is still too strong.

Is lavender tea safe for children?

An occasional weak cup is unlikely to harm an older child, but it is not recommended routinely. Case reports have linked lavender oil products to breast development in prepubertal boys and girls, and the compounds involved are the same ones in the tea. Chamomile is a better everyday choice for children.

Does lavender tea lower blood pressure?

Lavender aromatherapy has produced small drops in blood pressure and heart rate in several studies, consistent with its calming effect. No trial has measured this with the tea, and any change would be slight. If you take blood pressure medication, it is simply something to be aware of, not a reason to avoid it.
