HelloPharmacist Scorecard of Marjoram by Hawaii Pharm
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: certified organic marjoram extract in liquid form. It's delivered in a base of vegetable palm glycerin, pharmaceutical-grade alcohol, and purified water.
The alcohol and glycerin help extract and preserve the plant compounds.
Does it work?
Couldn't assess
The evidence for marjoram extract is not established in the data we hold. It's been studied for asthma, Parkinson disease, polycystic ovary syndrome (PCOS), and painful periods (dysmenorrhea), but all four have insufficient reliable evidence to rate whether it works.
That doesn't mean it doesn't — just that we don't have enough human trial data yet to say.
How safe is it?
Well-documented data
Marjoram is generally well tolerated as a food seasoning, but this is a concentrated liquid extract, and human safety data on extracts and essential oils is limited. The main concern is that in rare cases, some people develop skin reactions — either allergic contact dermatitis or flare-ups of existing skin conditions like perioral dermatitis.
During pregnancy, the safety data advises against medicinal or concentrated amounts because it hasn't been studied enough; food amounts are likely fine. During breastfeeding, safety data isn't on file, so talk to your doctor or pharmacist about whether it's right for you.
Meds to double-check
Moderate interaction found
Before taking this product, double-check any blood thinners or antiplatelet drugs you're on (aspirin, clopidogrel, warfarin, enoxaparin, and others). Also check any anticholinergic drugs (benztropine, procyclidine) or cholinergic drugs (donepezil, bethanechol) — marjoram may change how they work.
All three interactions are 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 marjoram extract might appeal to you if you're interested in herbal support, but it's not proven effective for any specific condition yet. If you take blood thinners, nerve medications, or any other prescription drug, check it here first — interactions with these are documented.
A short conversation with us before you start can make sure it fits your health picture.

Marjoram by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Hawaii Pharm's Marjoram liquid extract does interact with several important medication types.
The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs like aspirin, clopidogrel (Plavix), and enoxaparin. Lab research suggests marjoram extract can slow blood clotting, which might increase bleeding risk when combined with these medications — a moderate-severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Marjoram also interacts moderately with two nerve-signal drug categories. Anticholinergic drugs (like benztropine and procyclidine) and cholinergic drugs (like donepezil) may have their effects altered or reduced when taken with medicinal amounts of this extract.
These interactions are based on how marjoram behaves in the lab, not yet proven in people, but they're worth checking.
Altogether, these interactions span 337 individual medications. If you take any blood thinner, any drug for Parkinson's disease or overactive bladder, or any other prescription medication, please search your exact drugs below before you start.

certified organic Marjoram 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).
