Summer Savory and Nadroparin

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Nadroparin

Nadroparin falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Summer Savory interacts with.

In vitro research suggests that summer savory extract inhibits platelet aggregation and adhesion. Theoretically, summer savory 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.
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

Nadroparin (Fraxiparine) is a low molecular weight heparin you inject to thin the blood and prevent clots. The concern here is simple: both nadroparin and summer savory can nudge things toward easier bleeding, so stacking them could add up. In lab tests, compounds in summer savory (like carvacrol and thymol) appear to slow platelets from clumping together, which is the body's way of plugging small bleeds.

I'll be honest, this is theoretical and based only on test-tube work, not real patients. The pinch of savory in your soup is very unlikely to matter. Concentrated extracts or the essential oil are a different story. Watch for easy bruising, nosebleeds, bleeding gums, or dark stools, and check with your pharmacist or doctor before adding any savory supplement.

By severity: 3 major · 190 moderate · 25 minor.

From our pharmacist’s overview on the Nadroparin page

“Danshen heads my worry list for anyone on nadroparin (Fraxiparine), an injectable blood thinner used to prevent and treat clots. The herb has clot-blocking activity of its own, and since bleeding is already nadroparin's chief hazard, stacking the two invites trouble.”

About Summer Savory

What is Summer Savory?

  • Digestive upset and gas
  • Sore throat and cough
  • Antimicrobial
  • Mild diarrhea
  • Seasoning/culinary use

Summer savory is a common kitchen herb that has long been used as a tea or remedy for digestive complaints and minor infections. Food amounts are generally considered safe, but human studies supporting its medicinal use are very limited, so don't rely on it to treat any health condition. Talk with a pharmacist or doctor before using concentrated extracts or the essential oil.
