Is Lavender Tea Good for Cortisol?

DetoxWater Editorial Team•Published November 5, 2026

Partly: if stress is contributing to high cortisol, lavender tea may support relaxation, which could moderate the stress response, but a cortisol-lowering effect has not been established. The idea is to use lavender tea as part of a calming routine, not as a treatment for a hormone disorder.

Is lavender tea a reliable way to lower cortisol?

Lavender tea is not a proven way to lower high cortisol. It may be a pleasant choice when you want to unwind, but feeling calmer does not necessarily mean your cortisol has changed.

Cortisol is a necessary hormone that helps regulate metabolism, blood pressure and the body’s response to stress. It naturally varies during the day, so the goal is not to lower it as far as possible.

If a test suggests your cortisol is high, discuss the result with the clinician who ordered it. The cause and the timing and type of test matter more than choosing a particular drink. For a broader discussion, see the best drinks for high cortisol.

How might lavender tea affect cortisol?

When you perceive a threat or stressor, the brain signals the adrenal glands to release cortisol as part of the stress response. Once the stressor passes, that response generally settles. Relaxing activities may help you cope with stress, although their effects on cortisol vary.

Sipping a warm drink and taking a quiet break can be part of a relaxing routine. If lavender tea helps you feel less stressed, it might affect your short-term stress response, but the size and duration of any cortisol change from the tea are unknown.

The experience of drinking tea involves more than lavender itself: the setting, the break and your expectations may also matter. None of these observations shows that lavender tea can correct persistently high cortisol.

What does the research say about lavender and cortisol?

A 2021 systematic review and meta-analysis of randomized trials found that lavender interventions reduced anxiety compared with placebo or no treatment. That is more informative than personal anecdotes, but the review considered lavender interventions delivered in different ways—not just brewed lavender tea.

The finding is about anxiety, not proof that a cup of lavender tea lowers cortisol. It does not establish an effective amount of tea, how quickly cortisol might change or whether any change would last.

Different lavender preparations are not interchangeable. Results for an extract or inhaled lavender cannot be assumed to apply to the amount of lavender in a brewed drink. Research directly measuring cortisol after drinking lavender tea would be needed to answer the question more confidently.

For now, the distinction is practical: lavender tea may be worth enjoying as a calming ritual, but its ability to lower cortisol remains unproven. It should not replace assessment of an abnormal test result.

How can you use lavender tea safely?

Choose a packaged lavender tea intended for drinking and prepare it according to the label. Check whether it contains only lavender or is a blend; lavender flowers are naturally caffeine-free, but a blend may include caffeinated tea.

You can drink it during a quiet break or as part of an evening routine if you enjoy it. There is no established amount or schedule of lavender tea for lowering cortisol, and making it stronger is not known to improve that outcome.

Use food-grade lavender rather than fragrance products or ornamental flowers that may have been treated with chemicals. Do not add lavender essential oil to your drink: essential oils are concentrated and can be harmful if swallowed.

If you save leftover tea, refrigerate it promptly and drink it within 24 hours for best flavor. Discard it sooner if it becomes cloudy, slimy or sour-smelling.

Who should be careful with lavender tea?

If you are pregnant or breastfeeding, ask a healthcare professional before using lavender tea regularly; safety information is limited. Ask a child’s clinician before giving lavender tea for stress or cortisol. Avoid it if you have had an allergic reaction to lavender.

If you take sedatives, sleep medicines or other medicines that cause drowsiness, check with a pharmacist or clinician before drinking lavender tea regularly. Lavender may add to drowsiness, although the effects of the tea itself are not well studied. Do not stop or change prescribed medicines, including corticosteroids, without medical advice.

See a clinician if you have a high cortisol result or concerning changes such as easy bruising, wide purple stretch marks or increasing muscle weakness. These signs have different possible causes and need assessment rather than self-treatment with tea.

If someone swallows lavender essential oil, contact poison control or seek urgent medical help. Seek emergency help for trouble breathing, seizures or loss of consciousness.

Frequently asked questions

How quickly does lavender tea lower cortisol?

There is no established timeline because lavender tea has not been shown to lower cortisol. Feeling relaxed after a cup does not confirm a change in the hormone.

Can lavender tea replace a cortisol test?

No. A clinician can decide whether testing is appropriate and interpret the result in context.

Can lavender tea treat Cushing syndrome?

No. Cushing syndrome requires medical evaluation and treatment directed at its cause.
