Safflower 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 Safflower interacts with.

High doses of safflower oil might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Small clinical studies show that taking safflower oil, approximately 55 grams daily for 2-3 weeks, decreases platelet aggregation. However, taking lower doses of safflower oil, such as 5 grams daily for 4 weeks, does not seem to affect platelet function. In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.
Severity Moderate Likelihood Possible Evidence B

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

Danaparoid (Orgaran) is a blood thinner that lowers your blood's ability to clot. Safflower matters here because, at high concentrated doses, its oil can make your platelets stickier and slower to clump together. When you stack that mild anti-clotting effect on top of a true anticoagulant like danaparoid, the two can add up and nudge your bleeding risk higher.

What that could look like in real life: easy bruising, nosebleeds, bleeding gums, blood in your urine or stool, or cuts that are slow to stop. The good news is that cooking with safflower oil or eating normal food amounts is very unlikely to cause a problem. The studied concern came from large daily doses (around 20 to 55 grams). Before starting any concentrated safflower or CLA supplement, just check with your pharmacist or doctor first.

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. Nearly everything here, 202 of the 218 ingredients on file, carries some blood-thinning or antiplatelet activity of its own, and stacking that on top of an anti…”

About Safflower

What is Safflower?

Safflower
  • Heart and cholesterol support
  • Skin moisturizing
  • Menstrual cramps
  • Mild constipation
  • Weight management (oil)

Safflower is a thistle-like plant used mainly for its seed oil (a common cooking oil) and its colorful flowers. Safflower oil is a reasonable source of unsaturated fats, but strong proof that supplements treat specific diseases is limited. The flower extracts have much weaker evidence and should be used with caution, especially during pregnancy.
