Chinese Prickly Ash and Danaparoid

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Danaparoid

Danaparoid falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Chinese Prickly Ash interacts with.

Chinese prickly ash might inhibit platelet aggregation. Theoretically, combining Chinese prickly ash with anticoagulant or antiplatelet drugs might increase the risk of bleeding; avoid concomitant use. Some of these 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

Danaparoid (Orgaran) is a blood thinner given by injection to help prevent dangerous clots. Chinese Prickly Ash, the Sichuan pepper used in cooking, may have a mild ability to keep platelets (the tiny cells that help blood clot) from sticking together. If that's true, stacking it on top of danaparoid could nudge your bleeding risk a little higher. Think easy bruising, nosebleeds, bleeding gums, or cuts that are slow to stop.

That said, this is a theoretical concern based only on lab and animal data, not real-world cases. The flavor amounts you'd use in a meal are very unlikely to matter. Concentrated extracts are a different story, so check with your pharmacist or doctor before adding one.

From our pharmacist’s overview on the Danaparoid page

“Danshen, a Chinese herb sold for heart and circulation, is where I would start with danaparoid (Orgaran), an injectable blood thinner used to prevent and treat dangerous clots.

About Chinese Prickly Ash

What is Chinese Prickly Ash?

  • Digestive upset and stomach pain
  • Toothache and oral numbing
  • Antimicrobial and antiparasitic use
  • Cooking spice (Sichuan pepper)
  • Mild pain relief

Chinese Prickly Ash is the fruit husk of Zanthoxylum bungeanum, best known as the Sichuan pepper that creates a tingling, numbing sensation on the tongue. It is widely used in cooking and traditional Chinese medicine for digestive complaints and pain, but strong human evidence for medicinal benefits is limited. Use culinary amounts safely, but talk to a pharmacist or doctor before using concentrated extracts.
