HelloPharmacist Scorecard of Calming Formula by TerraVita
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
TerraVita's Calming Formula is a liquid blend with five active ingredients: spearmint, linden, German chamomile, sweet orange, and vervain — all in glycerite extract form, which means they're steeped in glycerin. The formula also contains glycerin as an inactive ingredient.
Spearmint, chamomile, and linden are traditionally used to promote relaxation, while orange and vervain round out the blend.
Does it work?
Insufficient evidence
The evidence we hold doesn't establish that this formula works for its intended calming effect. Spearmint, chamomile, and orange all show insufficient reliable evidence for anxiety-related uses in our data.
Linden's effectiveness ratings aren't documented for us, and we have no effectiveness data for vervain at all. That doesn't mean it won't help you — just that the clinical evidence we hold isn't there to back it up.
If you're looking for something with proven anti-anxiety effects, talk with your pharmacist about other options.
How safe is it?
Well-documented data
Spearmint is well tolerated orally in most people, though allergic reactions — including swelling of the soft palate and oral lichen planus — have occurred rarely. Chamomile can trigger severe allergic reactions, including anaphylaxis, especially in people sensitive to ragweed or related plants; it may also cause topical dermatitis.
Linden is generally well tolerated as a tea, but human safety data are limited. Orange is safe in food amounts, but concentrated extracts lack robust safety study.
We don't have pregnancy or breastfeeding safety data on file for linden and chamomile specifically. Vervain's safety profile is not documented in our data.
If you're pregnant, breastfeeding, or allergic to ragweed, check with your pharmacist before starting.
Meds to double-check
Major interaction found
Before using this product, check your medications against these drug types: OATP substrates, pravastatin, ivermectin, celiprolol, and fexofenadine (Major interactions with orange extract). Also check CNS depressants (sedating drugs), warfarin or other blood thinners, lithium, and drugs metabolized by CYP2D6, CYP2C9, or CYP3A4 enzymes (all Moderate interactions).
If you're taking quinolone antibiotics and the formula is calcium-fortified, that's also a Moderate concern. Use the medication checker on this page with your specific drug names.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This liquid formula combines common herbal relaxation aids, but it carries serious medication interactions — especially with the orange extract's effect on drug absorption and liver metabolism. If you take any prescription medications, OATP substrates, blood thinners, lithium, sedating drugs, or antihistamines, you'll need to run your exact meds through the interaction checker.
Even then, the evidence for its calming effect isn't established in the data we hold.

Calming Formula by TerraVita Drug Interactions
HelloPharmacist Interaction Report
TerraVita's Calming Formula contains five ingredients, and four of them have documented interactions with medications.
The most serious concern is orange tree extract — it carries Major-severity interactions with several drug types that can significantly reduce how your body absorbs them or increase their levels to unsafe amounts.
Read the full breakdown — every affected drug type, severity by severity
Orange tree extract is the culprit behind the Major interactions. It can drastically reduce absorption of OATP substrates (a broad class of medications), ivermectin, celiprolol, and fexofenadine — in some cases dropping levels by 90 percent or more.
It also increases pravastatin levels by about 149 percent. These are substantial changes that can make drugs either ineffective or dangerous.
You'll need to separate orange tree extract from these medications by at least 4 hours.
Spearmint and chamomile add Moderate interactions with CNS depressants (drugs that make you drowsy), so taking this formula alongside sedating medications could deepen drowsiness and other side effects. Chamomile also theoretically affects how your liver metabolizes several types of drugs — including those broken down by CYP2D6, CYP2C9, and CYP3A4 enzymes — and can increase warfarin's blood-thinning effects dangerously.
Linden carries a Moderate interaction with lithium; the diuretic effect could alter lithium levels and require a dose adjustment. We could not check vervain; no data is on file for it.
Altogether, these interactions span 1,174 individual medications. Before you start this product, search your exact medications in the checker below.

Warfarin (Coumadin)
German chamomile might increase the effects of warfarin and increase the risk of bleeding.
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 Glycerite Liquid Extract
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.
Orange Tree Glycerite Liquid Extract
Celiprolol (Celicard)
Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.
A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP). Recommend separating drug administration and consumption of sweet orange by at least 4 hours.
Ivermectin (Stromectol, Others)
Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.
A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP. For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90%. Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours.
Pravastatin (Pravachol)
Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.
A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice. Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.
Fexofenadine (Allegra)
Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.
Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72%. In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31%. Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP). Recommend separating drug administration and consumption of sweet orange by at least 4 hours.
P-Glycoprotein Substrates
Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.
Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates. In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.
Quinolone Antibiotics
Calcium-fortified sweet orange juice might reduce quinolone absorption.
Calcium binds to quinolones in the gut. Theoretically, the calcium in certain fortified orange juices can also bind to quinolone antibiotics and reduce their absorption and levels.
Linden Glycerite Liquid Extract
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.
