HelloPharmacist Scorecard of Calm Tea Chamomile Lavender Flower by Oat Mama

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.

Calm Tea contains three active ingredients: lavender, peppermint, and organic chamomile. Lavender is traditionally used for relaxation and has been studied for pain and anxiety-related conditions.

Peppermint is well-researched for digestive comfort and is a main ingredient in teas aimed at easing stomach upset. Chamomile's role in this blend is traditional support for calm, though we hold no interaction data for it.

There are no inactive ingredients listed.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: promotes restful sleep and eases digestion.
  • We looked for evidence on: Insomnia, Dyspepsia, Irritable bowel syndrome (IBS), Stress, sleep quality, digestive comfort.
  • The strongest evidence on file: Peppermint is rated "Likely Effective" for Irritable bowel syndrome (IBS) (Natural Medicines).
  • Also on file: Peppermint is rated "Possibly Effective" for Dyspepsia.
  • Also on file: Peppermint is rated "Insufficient Reliable Evidence To Rate" for Insomnia, Stress.

Lavender shows possibly effective evidence for period pain (dysmenorrhea), but evidence is insufficient or weak for hair loss (alopecia areata), anxiety before medical procedures, and cancer-related fatigue and pain. Peppermint fares better: it's likely effective for irritable bowel syndrome and possibly effective for indigestion, nausea from chemotherapy or medical procedures, and colon spasm during barium enemas.

The combination's overall effectiveness as a "calm tea" depends on which goal matters most to you—digestive ease has the stronger backing.

The evidence, ingredient by ingredient Lavender Peppermint

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lavender taken by mouth is generally well tolerated in the amounts found in food and in larger medicinal doses studied clinically, though headache, nausea, constipation, diarrhea, and indigestion can occur. Lavender essential oil is toxic if swallowed and can irritate skin in some people.

Peppermint tea is generally safe; the most common side effects are abdominal pain, belching, diarrhea, dry mouth, heartburn, nausea, and vomiting. Rare cases of allergic reactions and throat swelling have been reported.

Both ingredients carry cautions about limited safety data in certain forms—your provider should weigh in if you have questions about using medicinal amounts. Pregnancy and breastfeeding data for lavender are not adequately detailed in our records; peppermint is likely safe during both.

Talk with your doctor or pharmacist about whether this tea suits your individual situation.

Side effects, ingredient by ingredient Lavender Peppermint

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Peppermint, Lavender.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 927 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Calm Tea, check your exact medications against this page's search tool if you take central nervous system depressants (such as sedatives, sleep aids, or pain relievers), drugs metabolized by your liver as CYP3A4, CYP2C9, CYP2C19, or CYP1A2 substrates, or cyclosporine. These are Moderate-severity interactions with peppermint and lavender, though human evidence is limited.

We could not check organic chamomile for interactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This tea pairs two digestive herbs—peppermint is likely effective for IBS and indigestion—with lavender, which has weaker evidence for calming but may add a sedative touch. If you take medications processed by your liver or any CNS depressants (sleeping pills, sedatives, pain relievers), check them against the interaction tool before brewing.

Even without interactions, chat with your doctor or pharmacist if you're pregnant, breastfeeding, or on multiple medications.

For each ingredient in Calm Tea Chamomile Lavender Flower with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Peppermint5 drug types · 796 drugs

Cyclosporine (Neoral, Sandimmune)

Theoretically, peppermint oil might increase the levels and adverse effects of cyclosporine.
In animal research, peppermint oil inhibits cyclosporine metabolism and increases cyclosporine levels. Inhibition of cytochrome P450 3A4 (CYP3A4) may be partially responsible for this interaction. An interaction between peppermint oil and cyclosporine has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, peppermint might increase the levels of CYP2C19 substrates.
In vitro research shows that peppermint oil inhibits CYP2C19. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, peppermint might increase the levels of CYP2C9 substrates.
In vitro research shows that peppermint oil inhibits CYP2C9. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, peppermint might increase the levels of CYP3A4 substrates.
Clinical research in healthy volunteers shows that a single dose of peppermint oil 600 mg inhibits CYP3A4 enzymes and increases the AUC of felodipine, a CYP3A4 substrate. However, in vitro research suggests that peppermint oil only inhibits CYP3A4 at very high concentrations.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, peppermint might increase the levels of CYP1A2 substrates.
In vitro and animal research shows that peppermint oil and peppermint leaf inhibit CYP1A2. However, in clinical research, peppermint tea did not significantly affect the metabolism of caffeine, a CYP1A2 substrate. It is possible that the 6-day duration of treatment may have been too short to identify a difference.

Likelihood Possible Evidence B

Lavender1 drug type · 248 drugs

Cns Depressants

Theoretically, lavender might potentiate the therapeutic effects and adverse effects of CNS depressants.
Laboratory research suggests that lavender has sedative effects. However, clinical studies in patients taking oral lavender oil (Silexan) 160 mg for 10 weeks or taking lavender flower powder 1 gram daily for 2 months have not reported side effects of drowsiness, sedation, or sleepiness. There is still some concern that higher doses or different preparations of lavender might have additive effects with CNS depressant medications.

Calm Tea Chamomile Lavender Flower by Oat Mama: Common Questions

Does Calm Tea Chamomile Lavender Flower by Oat Mama interact with any medications?
Yes. Based on its ingredients, Calm Tea Chamomile Lavender Flower has a known interaction with 926 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Calm Tea Chamomile Lavender Flower contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this tea actually help me relax?
Lavender has lab evidence of sedative effects, but clinical trials haven't shown side effects from the doses studied, so real-world calming is unclear. Peppermint's strength is digestive comfort, not relaxation. If you're looking for proven calm, the science here is weaker than for IBS or indigestion relief.
What are the most common side effects?
From lavender: breath odor, constipation, diarrhea, indigestion, belching, headache, and nausea. From peppermint: abdominal pain, belching, diarrhea, dry mouth, heartburn, nausea, and vomiting. Most people tolerate the tea well, but if your stomach is sensitive, start with a small amount.
Is this safe during pregnancy or breastfeeding?
Peppermint is likely safe while pregnant or nursing. We don't have detailed safety information on file for lavender during pregnancy and breastfeeding—talk with your doctor or pharmacist before using this tea in those situations.
Can I use this if I take sleeping pills or other sedative drugs?
Lavender might amplify the drowsy effects of CNS depressants like sleep aids—a Moderate interaction. Check your specific medications with the tool on this page and ask your doctor or pharmacist before combining them with this tea.
Does peppermint interfere with how my body breaks down medications?
Yes, peppermint oil can theoretically slow your liver's processing of several drug types, raising their levels in your blood. Lab and animal research backs this; human evidence is mixed. If you're on blood pressure meds, heart drugs, immunosuppressants, or other liver-processed medications, use the checker and confirm with your pharmacist.
