ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Aspirin, Aluminum Hydroxide, Codeine Phosphate, Magnesium Hydroxide

Aspirin, Aluminum Hydroxide, Codeine Phosphate, Magnesium Hydroxide falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Thyme interacts with.

Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that thyme leaf extract has antiplatelet effects. However, this effect has not been observed in humans.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the piece that matters with this combo product: it contains aspirin, which thins the blood by keeping platelets from clumping together. In lab dishes and animal studies, thyme extract has shown a mild blood-thinning effect of its own. So in theory, stacking concentrated thyme on top of aspirin could add up and make you a little more prone to bruising, nosebleeds, or stomach upset and bleeding.

I want to be honest, though: this effect has not actually shown up in people, and the seasoning amount of thyme you'd sprinkle on dinner is very unlikely to cause any trouble. The concern, if any, is with concentrated thyme supplements or oils. If you take those regularly, just mention it to your pharmacist or doctor so they can keep an eye out.

About Thyme

What is Thyme?

Thyme
  • Cough and respiratory congestion
  • Sore throat
  • Digestive upset
  • Antimicrobial and antiseptic uses
  • Flavoring in cooking

Thyme is a common kitchen herb that has long been used for coughs, sore throats, and digestive complaints. It is generally safe in the amounts found in food, and some cough products that combine thyme with other herbs have modest supporting evidence, but high-quality research on thyme alone is limited. The concentrated essential oil should never be swallowed undiluted.
