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.
What’s inside
Low disclosure
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
Moderate interaction found
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.

Calm Tea Chamomile Lavender Flower by Oat Mama Drug Interactions
HelloPharmacist Interaction Report
Calm Tea Chamomile Lavender Flower by Oat Mama contains lavender and peppermint, both of which have documented interactions with medications.
The most serious concern is lavender's potential to enhance the effects of central nervous system depressants (drugs that make you drowsy or calm your brain activity) — a Moderate interaction. While lab studies show lavender has sedative properties, clinical trials of oral lavender haven't reported this effect, but the theoretical risk remains.
Read the full breakdown — every affected drug type, severity by severity
Peppermint brings several Moderate interactions through the way your liver processes certain drugs. Peppermint oil may increase levels of medications metabolized by three liver enzymes (CYP2C19, CYP2C9, and CYP3A4 substrates), and it may raise cyclosporine levels and side effects.
In vitro research shows these effects; clinical evidence is limited or mixed — one human study of CYP3A4 showed a measurable increase, but peppermint tea didn't significantly affect caffeine metabolism in another trial. Peppermint also carries a Minor interaction with CYP1A2 substrates.
We could not check organic chamomile — no interaction data is on file for it. Altogether, these interactions span 927 individual 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.
Peppermint
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.
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.
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.
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.
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.
Lavender
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.
