At a glance
- A 2019 systematic review of eight RCTs found chamomile effective for easing PMS symptoms, though most trials tested extracts or capsules, not brewed tea (2).
- There's no established 'tea dose' for PMS. Most people drink 1 to 3 cups a day in the days before their period as a calming habit.
- Chamomile's compounds, like apigenin and glycine, have anti-spasmodic and anti-anxiety effects studied in PMS and other conditions (1).
- Side effects are uncommon: watch for allergic reactions if you're sensitive to ragweed, daisies or chrysanthemums, and check before mixing with blood thinners.
- Chamomile tea isn't a substitute for treatments guidelines recommend for more severe symptoms, like SSRIs taken only in the luteal phase (9).
Strength of evidence
Mixed evidence
A systematic review of eight RCTs found chamomile effective for easing PMS symptoms, but most trials tested concentrated extracts or capsules rather than brewed tea, so the evidence for tea itself is limited and PMDD hasn't been studied specifically (2).
What is chamomile tea good for?
Chamomile has been used for centuries as a calming drink for sleep, an upset stomach and general tension. A 2016 systematic review in Electronic Physician looked at decades of research on Matricaria recutita (chamomile) and found it studied for anti-inflammatory, antispasmodic, antidepressant and calming effects, among others, with premenstrual syndrome named specifically as one condition it may help [1].
The plant contains compounds like apigenin and bisabolol, linked to easing inflammation and muscle spasm, and others like glycine and certain flavonoids tied to calming anxiety.
People use chamomile tea for:
- Trouble falling asleep
- An upset stomach or mild cramping
- Everyday tension or worry
- Period cramps and the restlessness that can show up before a period
Sleep often gets lighter in the days before a period, and a warm, caffeine-free drink can be a steady anchor on harder nights.
Cortisol, the body's main stress hormone, is typically a little lower in the luteal week than in the follicular week, according to a meta-analysis of 778 women [3].
The irritability many people feel before their period has more to do with how the brain reacts to shifts in progesterone's byproducts (Dubey et al., 2017). A calming evening habit like warm tea can still help with that.
None of this makes chamomile a guaranteed fix. It's a plant with studied effects worth taking seriously, not a replacement for care when symptoms are severe.

Does chamomile tea help PMS?
The best evidence linking chamomile and PMS comes from a 2019 systematic review in the Journal of Pharmacopuncture, which pulled together eight randomized controlled trials and concluded chamomile is effective for easing PMS symptoms [2]. The trials pointed to real mechanisms: anti-spasmodic compounds like apigenin and quercetin that ease cramping, and anti-anxiety compounds like glycine that may calm mood symptoms.
Most of those trials tested chamomile as a standardized extract or capsule, not a cup of brewed tea. Tea delivers a much smaller, less consistent dose of the active compounds than a concentrated extract. That doesn't mean tea does nothing, but it means the research doesn't translate directly to drinking a cup and feeling calmer by evening.
| Form | What the research tested | Evidence strength |
|---|---|---|
| Brewed tea (1 to 2 cups) | Mostly traditional use, not tested on its own for PMS | Limited |
| Standardized extract or capsule | Used in the 8 RCTs reviewed for PMS symptom relief | Moderate [2] |
| Essential oil or topical use | Traditional use for cramps, not tested for PMS | Not studied for PMS |
Think of chamomile tea as a small support alongside other PMS treatment, not the main plan. If your symptoms are severe enough to disrupt your week every month, chamomile tea alone won't be enough.
Guidelines recommend options like SSRIs, which can work taken only in the luteal phase [4], along with certain hormonal contraceptives and CBT (ACOG Clinical Practice Guideline No. 7, 2023), decided with a doctor. Chamomile tea isn't a substitute for these treatments when symptoms are more severe.

How do you make chamomile tea?
Making chamomile tea is simple, and how you brew it affects how much of its calming compounds end up in your cup. Covering the cup matters more than people think, since some of those compounds can escape with the steam if it's left open.
- Use one chamomile tea bag or about 2 to 3 grams of dried chamomile flowers.
- Heat water until it's just below boiling, not a hard boil.
- Pour the water over the chamomile and cover the cup so steam doesn't escape.
- Steep for 5 to 10 minutes. A longer steep draws out more of the active compounds.
- Strain if you used loose flowers, then drink it warm.
A slightly longer steep than you'd use for a quick cup of green tea makes sense here, since chamomile's compounds release slowly into hot water. If you only have tea bags, pressing them lightly after steeping releases a bit more of the plant's oils, though steeping too long can make the tea taste more bitter.
How much chamomile tea should you drink?
Researchers haven't set an established amount for chamomile tea on its own. The RCTs behind chamomile's PMS evidence used extracts and capsules with specific doses, not cups of tea [2], so there's no tested 'tea dose' to point to.
Most people who use it drink 1 to 3 cups a day in the week or two before their period, often in the evening as part of winding down. That's a reasonable, low-risk amount for most adults.
A caffeine-free cup can also be part of signaling to your body that the day is winding down. Drinking more than that adds habit and fluid more than extra benefit, since tea is a weaker dose of chamomile's active compounds than a supplement.
If you want something to help you track how the days before your period feel, alongside whatever calming habits you build in, Niyora is a PMS and PMDD support app. Its Moon feature lets you write down what's going on and see it from a calmer angle, which can sit next to a cup of tea rather than replace it.
Are there side effects to watch for?
Chamomile is generally considered low-risk, and mild side effects like stomach upset or drowsiness are uncommonly reported in traditional use. [1] reviewed chamomile's broader therapeutic effects, from osteoarthritis to mild anxiety, but didn't focus on safety data specifically. Still, it isn't risk-free for everyone.
- Allergic reactions, especially if you're sensitive to ragweed, daisies or chrysanthemums
- Drowsiness, which is often the point in the evening but worth noting before driving
- A possible interaction with blood thinners like warfarin
- Limited safety data in pregnancy, so many clinicians suggest caution or checking first

Questions people ask
Does chamomile tea really help PMS symptoms?+
Chamomile tea may ease mild PMS symptoms like cramps or a restless mood, but most of the research behind it tested concentrated extracts, not brewed tea. A systematic review of eight RCTs found chamomile supplements effective for PMS, so tea's lighter dose likely has a milder effect (2).
Can chamomile tea help with PMDD?+
Chamomile tea hasn't been studied specifically for PMDD, a diagnosis that needs mood symptoms severe enough to disrupt daily life in the week before a period. It may still feel calming as part of an evening routine, but it isn't a substitute for SSRIs, therapy or other PMDD treatments a doctor might recommend.
How many cups of chamomile tea should I drink before my period?+
There's no established amount for chamomile tea and PMS specifically, since the studies used extracts, not tea. Most people drink 1 to 3 cups a day in the days before their period, often in the evening, which is a reasonable, low-risk amount for most adults.
Who shouldn't drink chamomile tea?+
People allergic to ragweed, daisies or chrysanthemums can react to chamomile too, with symptoms like itching or swelling. Anyone on blood thinners, pregnant, or unsure about an interaction with another medication should check with a doctor or pharmacist before drinking it regularly.
When does chamomile tea stop being enough on its own?+
If PMS symptoms take a week of every month, or you have thoughts of hurting yourself, see a doctor and bring two months of daily notes. Chamomile tea can sit alongside treatment, but it isn't enough on its own at that level.
