Swallowroot and Aspirin, Carisoprodol

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Aspirin, Carisoprodol

Aspirin, Carisoprodol falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Swallowroot interacts with.

Theoretically, swallowroot might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that swallowroot inhibits platelet aggregation.
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

The medicine you're asking about, Soma Compound, blends carisoprodol (a muscle relaxant) with aspirin. The piece that matters here is the aspirin, which already thins your blood a bit by making platelets less sticky. Lab studies suggest Swallowroot may do something similar, gently slowing how platelets clump together. Stack the two and, in theory, you could bruise more easily, bleed a little longer from small cuts, or rarely notice things like nosebleeds or stomach upset.

Keep in mind this is based only on test-tube and animal research, not on people, so the real-world risk is unclear. Pickled or flavored culinary amounts are unlikely to be a problem, but concentrated supplements are a different story. Please run it by your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Aspirin, Carisoprodol page

“This is one of the longer interaction lists on the site, and for Soma Compound (aspirin plus the muscle relaxant carisoprodol) the caution is earned. Of the 266 supplements and herbs on file, just over 200 push in the same direction as aspirin itself, thinning the blood and raising the odds of bleeding.”

About Swallowroot

What is Swallowroot?

  • Digestive complaints
  • General tonic and appetite stimulant
  • Blood purifier in folk medicine
  • Antimicrobial and food preservative
  • Cooling drink in hot weather

Swallowroot (Decalepis hamiltonii) is a root used in South Indian folk medicine and as a food flavoring, often pickled or made into a cooling drink. Modern scientific evidence for its health benefits in people is very limited, resting mostly on laboratory and animal studies, so its effectiveness is not proven. If you are considering it, talk with your pharmacist or doctor first, especially during pregnancy or breastfeeding.
