HelloPharmacist Scorecard of Calming Formula Powder by TerraVita Premium Collection
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
Calming Formula Powder contains 5 ingredients: chamomile powder, spearmint powder, linden sapwood powder, blue vervain powder, and orange powder. Chamomile and spearmint are traditional herbs used in calming blends for their mild sedative properties.
Linden is included for its traditional use in relaxation formulas. The product also contains inactive ingredients that serve as fillers or carriers.
Does it work?
Not established
The effectiveness data we hold are limited. Chamomile has insufficient reliable evidence to rate for anxiety, ADHD, hay fever, and cancer-related loss of appetite.
Spearmint similarly has insufficient evidence for cognitive decline, cognitive function, flatulence, IBS, nausea after surgery, and osteoarthritis. No effectiveness ratings are on file for linden, blue vervain, or orange powder for any condition.
How safe is it?
Well-documented data
Chamomile is generally well tolerated but can cause allergic reactions in people sensitive to ragweed and related plants; severe reactions including anaphylaxis have been reported rarely. It's best avoided during pregnancy unless your doctor approves, and you should check with your pharmacist before using it while breastfeeding.
Spearmint is generally safe in food or tea amounts, but concentrated supplements need caution, especially in pregnancy. Linden is generally well tolerated as a tea but has limited human safety data; it's best avoided during pregnancy and lactation unless your doctor advises otherwise.
Blue vervain and orange powder have no safety data on file.
Meds to double-check
Moderate interaction found
Before you take this product, double-check with your pharmacist if you're on warfarin or other blood thinners (moderate severity), sedating medications or CNS depressants (moderate severity), drugs that affect the liver, lithium, oral contraceptives, estrogen therapy, or tamoxifen. The product contains multiple ingredients that theoretically may slow the breakdown of several broad drug categories—CYP2D6, CYP2C9, and CYP3A4 substrates—so a full medication review is important.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This calming blend may be worth trying if you're looking for a traditional herbal approach to relaxation, but it's not a substitute for medical treatment. If you take blood thinners, sedating medications, lithium, cancer drugs, birth control, or hormone therapy, check your specific medications with the tool on this page before you start.
Talk to your pharmacist about whether it fits your health situation.

Calming Formula Powder by TerraVita Premium Collection Drug Interactions
HelloPharmacist Interaction Report
Calming Formula Powder by TerraVita Premium Collection contains several ingredients with documented interactions to check before you start.
The most serious finding involves chamomile and warfarin (a blood thinner). One case reported a patient on warfarin who drank 4–5 cups of chamomile tea daily and developed severe bleeding with a dangerously high clotting time.
Read the full breakdown — every affected drug type, severity by severity
Chamomile also has moderate interactions with sedating medications (CNS depressants)—theoretically it could add to their drowsiness. It may slow how your body breaks down certain drug classes: CYP2D6 substrates, CYP2C9 substrates, and CYP3A4 substrates.
These are broad drug groups, so this matters if you're on heart medications, mental-health drugs, or immunosuppressants, among others. Chamomile may also reduce the effectiveness of oral contraceptives and estrogen therapy if you take large amounts, and it could interfere with tamoxifen (a cancer drug).
Spearmint powder has moderate interactions with sedating drugs and hepatotoxic drugs (medications that stress your liver). Linden sapwood may increase lithium levels and effects, a concern if you take it for bipolar disorder.
We couldn't check blue vervain or orange powder—no interaction data are on file for them.
Altogether, these interactions span 1,114 individual medications. Use the medication checker on this page to run through your exact prescriptions before you add this product.

In vitro, German chamomile has demonstrated antiestrogenic activity. Theoretically, concomitant use of large amounts of German chamomile might interfere with contraceptive drugs through competition for estrogen receptors.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, German chamomile might inhibit CYP2C9 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP2C9. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP2C9 in patients taking German chamomile.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, German chamomile might inhibit CYP2D6 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP2D6. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP2D6 in patients taking German chamomile.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, German chamomile might inhibit CYP3A4 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP3A4. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP3A4 in patients taking German chamomile.
Estrogens

In one case, a 70-year-old female taking warfarin developed retroperitoneal hematoma and bilateral recti muscle bleeding along with an INR of 7.9 following ingestion of German chamomile tea 4-5 cups daily and use of a topical chamomile-based lotion applied 4-5 times daily.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, German chamomile might inhibit CYP1A2 and increase levels of drugs metabolized by these enzymes.
In vitro and animal research shows that German chamomile might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP1A2 in patients taking German chamomile.
Spearmint, Powder
Cns Depressants
Theoretically, spearmint might alter the sedative effects of CNS depressants.
Animal research suggests that (-)-carvone, a major constituent of spearmint, has sedative effects. However, in humans, chewing spearmint-flavored gum induced arousal effects.
Hepatotoxic Drugs
Theoretically, high doses of spearmint might increase the risk of liver damage when taken with hepatotoxic drugs.
Animal research suggests that drinking spearmint tea for 30 days can increase markers of liver damage, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and cause liver degeneration and necrosis, in a dose-dependent manner. This effect has not been reported in humans.
Linden Sapwood, Powder
Lithium
Theoretically, due to its potential diuretic effects, linden might increase the effects and adverse effects of lithium.
Linden is thought to have diuretic properties. The dose of lithium might need to be decreased.
