HelloPharmacist Scorecard of Marjoram Leaf 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
Full disclosure
This product contains one active ingredient: Marjoram Leaf Glycerite Liquid Extract. It's made by extracting marjoram leaf in glycerin, a common liquid base.
The only other ingredient is glycerin itself, which serves as the extraction medium.
Does it work?
Couldn't assess
The evidence for marjoram isn't established in our data. We hold effectiveness ratings for asthma, Parkinson disease, polycystic ovary syndrome (PCOS), and dysmenorrhea — but for all four conditions, there's insufficient reliable evidence to rate whether it works.
That doesn't mean it doesn't; it means the research isn't there yet to say one way or the other.
How safe is it?
Well-documented data
Marjoram is generally well tolerated as a food seasoning, but this is a concentrated medicinal extract — and concentrated extracts have limited human safety data. Adverse effects are uncommon, though isolated cases of skin reactions (dermatitis) have been reported, including allergic reactions in children with eczema and a flare-up of perioral dermatitis in one adult after eating marjoram-seasoned food.
Don't use this product in medicinal amounts during pregnancy; the safety data advises against it. For breastfeeding, we don't have enough safety information on file — talk with your doctor or pharmacist before using it.
Food amounts of marjoram are likely fine, but this liquid extract is a concentrated dose, so the caution applies.
Meds to double-check
Moderate interaction found
Before you take this, double-check with your pharmacist if you're on blood thinners or antiplatelet drugs (aspirin, clopidogrel, enoxaparin, and others), anticholinergic drugs (for Parkinson's, overactive bladder, or motion sickness), or cholinergic drugs (like donepezil for Alzheimer's). All three drug classes interact at Moderate severity.
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 extract is most appropriate for people looking to use marjoram in concentrated form for non-acute purposes, with no blood thinners or neurological medications on board. If you take anticoagulants, anticholinergic drugs, or cholinergic drugs, you'll need to check with your pharmacist first.
Pregnant or breastfeeding? Skip it or talk to your doctor.
Ask your pharmacist before starting.

Marjoram Leaf by TerraVita Drug Interactions
HelloPharmacist Interaction Report
TerraVita's Marjoram Leaf Liquid Extract does interact with medications.
The main concern is with blood thinners and antiplatelet drugs (like aspirin, clopidogrel, and enoxaparin). In lab studies, marjoram extract slowed down how platelets clump together, so taking it in medicinal amounts alongside these drugs could raise your bleeding risk — that's a Moderate interaction.
Read the full breakdown — every affected drug type, severity by severity
Marjoram also affects how your body uses two other drug classes. It can interfere with anticholinergic drugs (used for conditions like Parkinson's and overactive bladder), potentially lowering their effectiveness — also Moderate severity.
On the flip side, it may boost cholinergic drugs (like donepezil for Alzheimer's), which could increase side effects like nausea and muscle weakness — again Moderate.
Altogether, these interactions span 337 individual medications. If you take any blood thinner, any drug for Parkinson's or bladder control, or any medication for memory or nerve function, run it through the checker below before you start this product.

For each ingredient in Marjoram Leaf with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Marjoram Leaf Glycerite Liquid Extract
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).
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.
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).
