Interaction report

Tarragon and Aspirin, Ethoheptazine, Meprobamate

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Tarragon interacts with whole categories of medication. Aspirin, Ethoheptazine, Meprobamate falls into 2 of those categories, so it can interact with Tarragon in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Aspirin, Ethoheptazine, Meprobamate

Aspirin, Ethoheptazine, Meprobamate falls under CNS DEPRESSANTS — the group Tarragon interacts with.

Evidence from animal research suggests that tarragon essential oil can cause sedation and motor impairment when administered intraperitoneally at a dose of 1 mL/kg. Theoretically, concomitant use of tarragon with CNS depressants, including antihistamines, barbiturates, benzodiazepines, and tricyclic antidepressants, may increase sedative and other adverse effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Equagesic is a combo medicine, and one part of it, meprobamate, already works as a calming agent that can make you drowsy. The concern here is that tarragon, in concentrated extract or essential oil form, has shown sedative effects in animal studies. So in theory, pairing the two could pile on the sleepiness, leaving you more groggy, foggy-headed, or unsteady on your feet than usual.

I'll be honest though, this is weak, lab-and-animal-only evidence, not something proven in people. A sprinkle of tarragon in your cooking is very unlikely to cause any trouble. The caution really applies to strong supplement doses or the essential oil. If you're considering those, just run it by your pharmacist or doctor first.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Aspirin, Ethoheptazine, Meprobamate also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Evidence from in vitro research suggests that tarragon extract inhibits platelet aggregation and adhesion. Theoretically, tarragon might increase the risk of bleeding when used 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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Equagesic combines aspirin with ethoheptazine (a pain reliever) and meprobamate (a calming muscle relaxant). The piece that matters here is the aspirin, which already thins your blood a bit by keeping platelets from clumping together. Lab studies suggest tarragon may nudge platelets in the same direction, so in theory stacking the two could add up to a higher bleeding risk, things like easy bruising, nosebleeds, or stomach upset and irritation.

I want to be honest about the strength of this: it's only test-tube research, not proven in people, so it's more of a caution than a real alarm. A sprinkle of tarragon in cooking is very unlikely to matter. Concentrated tarragon extracts or oil are where I'd be more careful. Just check with your pharmacist or doctor before adding a tarragon supplement.

From our pharmacist’s overview on the Aspirin, Ethoheptazine, Meprobamate page

“Equagesic combines aspirin with two sedating pain relievers, ethoheptazine and meprobamate, which means supplements can go wrong in two directions at once, and this list earns genuine care before you mix in any of them. Most of the entries add to aspirin's blood-thinning effect and raise bleeding risk, while a large second group deepen…”

About Tarragon

What is Tarragon?

Tarragon
  • Digestive upset
  • Appetite stimulation
  • Sleep and mild restlessness
  • Toothache and oral discomfort
  • Blood sugar support (preliminary)
  • Culinary flavoring

Tarragon is a flavorful culinary herb that has been used in traditional medicine for digestion, sleep, and other complaints, but solid human evidence for any health benefit is lacking. Amounts used in cooking are generally considered safe, while concentrated extracts and the essential oil should be used cautiously because tarragon contains estragole, a compound studied for possible safety concerns. Talk to your pharmacist or doctor before using tarragon as a supplement.
