HelloPharmacist Scorecard of Marjoram by Herbal Terra
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 Berry Extract, Dry. It's formulated as a liquid using alcohol, water, and glycerin as inactive ingredients to help dissolve and preserve the extract.
Does it work?
Couldn't assess
The evidence we have for marjoram doesn't establish it as effective for the conditions we've reviewed. We have insufficient reliable evidence to rate it for asthma, Parkinson disease, polycystic ovary syndrome (PCOS), or painful menstrual cramps (dysmenorrhea).
If you're considering it for one of these, talk with your doctor about what the research actually shows right now.
How safe is it?
Well-documented data
Marjoram is generally safe as a food seasoning, but concentrated extracts like this one have limited human safety data. In medicinal or concentrated amounts, you should avoid it during pregnancy—the safety data just isn't there.
The same caution applies to breastfeeding: food amounts are likely fine, but medicinal doses haven't been studied enough. Side effects are uncommon but possible.
A small number of people have developed allergic contact dermatitis or skin inflammation (perioral dermatitis) related to marjoram exposure, though these are rare. If you notice any skin reactions or rash after starting this product, stop using it and contact us.
Meds to double-check
Moderate interaction found
Before you take this product, double-check your medications if you're on blood thinners or antiplatelet drugs like aspirin, clopidogrel, or enoxaparin (Moderate risk). Also verify any anticholinergic medications for Parkinson's or urinary conditions, or cholinergic drugs like donepezil for Alzheimer's (both Moderate).
Use the checker on this page with your exact medications.
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.
Marjoram extract is best for people taking no blood thinners or neurological medications who are not pregnant or breastfeeding. If you take any anticoagulants, antiplatelet drugs, or medications for Parkinson's or Alzheimer's, check with your pharmacist first.
Pregnant and breastfeeding people should avoid medicinal doses. Talk to your pharmacist before starting, especially if you're on any prescriptions.

Marjoram by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra's Marjoram Berry Extract Liquid does interact with medications.
The most serious concern is with blood thinners and antiplatelet drugs like aspirin, clopidogrel (Plavix), and enoxaparin. In vitro research suggests marjoram extract can inhibit platelet aggregation (how blood cells clump together), which means it might increase bleeding risk when combined with these drugs in medicinal amounts.
Read the full breakdown — every affected drug type, severity by severity
Marjoram also interacts with two groups of neurological medications. Anticholinergic drugs—used for conditions like Parkinson's and overactive bladder—may become less effective when taken with marjoram in medicinal doses because marjoram can inhibit acetylcholinesterase activity.
Cholinergic drugs like donepezil (Aricept), used for Alzheimer's, might have additive effects and raise the risk of cholinergic side effects (increased saliva, sweating, muscle weakness) if combined with marjoram in medicinal amounts.
Altogether, these interactions span 337 individual medications. We've checked the one active ingredient in this product.

Marjoram Berry Extract, Dry
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).
