HelloPharmacist Scorecard of Marjoram Leaf Mint Flavor 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: marjoram leaf glycerite liquid extract. It's a concentrated liquid form of the marjoram herb.

The other ingredients — glycerin and mint flavor — are inactive, used to dissolve and flavor the extract.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Marjoram product and its label doesn't state a use — see Marjoram's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for marjoram in treating asthma, Parkinson disease, polycystic ovary syndrome (PCOS), and dysmenorrhea is insufficient in our data — we don't have enough reliable studies to say whether it works for these uses or not.

The evidence, ingredient by ingredient Marjoram

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Marjoram is generally well tolerated as a food seasoning. However, concentrated extracts like the one in this product have limited human safety data.

A few people have had skin reactions: allergic contact dermatitis was noted in children using essential oils that included marjoram, and one case report described a woman whose skin inflammation worsened after eating marjoram-seasoned food and cleared when she stopped. In pregnancy, the safety data advises against medicinal or concentrated amounts — stick to food amounts only if you're pregnant.

For breastfeeding, we don't have safety information on file, so talk with your pharmacist or doctor before using medicinal doses.

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?
  • 1 of the 1 matched ingredient can interact with medications — Marjoram.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 338 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 you take this product, double-check with your pharmacist if you use blood thinners or antiplatelet drugs (like aspirin or clopidogrel) — marjoram may increase bleeding risk. Also check if you take anticholinergic drugs (for Parkinson's, overactive bladder, or spasm) or cholinergic drugs (for myasthenia gravis or memory).

Both carry moderate interaction risk.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is for people interested in marjoram's traditional uses, but the evidence for its effectiveness isn't established. If you take blood thinners, anticholinergic drugs, or cholinergic drugs, check your exact medications before starting — there's a moderate interaction risk.

Talk with your pharmacist, especially if you're pregnant or breastfeeding.

Marjoram Leaf Glycerite Liquid Extract3 drug types · 338 drugs

Anticholinergic Drugs

In vitro research suggests that marjoram extract can inhibit acetylcholinesterase activity. Theoretically, using marjoram in medicinal amounts along with anticholinergic drugs might decrease the effectiveness of marjoram or the anticholinergic agent.
Some anticholinergic drugs include atropine, benztropine (Cogentin), biperiden (Akineton), procyclidine (Kemadrin), and trihexyphenidyl (Artane).

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

In vitro research suggests that marjoram extract inhibits platelet aggregation and adhesion. Theoretically, marjoram might increase the risk of bleeding when used in medicinal amounts along with antiplatelet or anticoagulant drugs.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Cholinergic Drugs

In vitro research suggests that marjoram extract can inhibit acetylcholinesterase activity. Theoretically, using marjoram in medicinal amounts along with cholinergic drugs might have additive effects and increase the risk of cholinergic side effects.
Cholinergic drugs include bethanechol (Urecholine), donepezil (Aricept), echothiophate (Phospholine Iodide), edrophonium (Enlon, Reversol, Tensilon), neostigmine (Prostigmin), physostigmine (Antilirium), pyridostigmine (Mestinon, Regonol), succinylcholine (Anectine, Quelicin), and tacrine (Cognex).

Marjoram Leaf Mint Flavor by TerraVita: Common Questions

Does Marjoram Leaf Mint Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Marjoram Leaf Mint Flavor has a known interaction with 338 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Marjoram Leaf Mint Flavor contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Is marjoram safe to use if I'm pregnant?
No — medicinal or concentrated amounts should be avoided in pregnancy due to lack of safety data. Food amounts (like seasoning) are likely fine, but don't use this concentrated extract if you're pregnant. Talk with your doctor or pharmacist for personalized advice.
Can marjoram cause skin problems?
It's rare, but yes. A small number of children using marjoram essential oil developed allergic skin reactions, and one case report describes a woman whose skin inflammation got worse after eating marjoram-seasoned food. If you notice a rash or skin irritation, stop using it and contact your doctor.
Does this product actually work for asthma, PCOS, or period pain?
We don't have enough reliable evidence to say. The research available to us isn't strong enough to confirm marjoram works for asthma, Parkinson disease, PCOS, or dysmenorrhea — so we rate those as insufficient evidence.
What is a glycerite, and why is it used here?
A glycerite is an extract made by soaking an herb in glycerin instead of alcohol. It's a gentler way to concentrate the herb's compounds, and glycerin also adds a slightly sweet taste that works well with this product's mint flavor.
Is it safe to use this if I'm on a blood thinner?
No — not without checking with your pharmacist first. Lab studies show marjoram slows how blood platelets stick together. When you combine that with blood thinners like aspirin or warfarin, there's a moderate risk of bleeding. Use the medication checker on this page with your exact drugs, or call your pharmacist before starting.
