Lion's Mane Mushroom 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 Lion's Mane Mushroom interacts with.

Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
In vitro research suggests that lion's mane mushroom extracts can inhibit 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

Danaparoid (Orgaran) is an injectable blood thinner that helps stop dangerous clots from forming. Lion's mane works in a completely different way, but here's the overlap that matters: in lab dish studies, lion's mane extracts seemed to make platelets (the cells that help blood clot) a little less sticky. Put that on top of a medicine that already slows clotting, and the concern is that your blood could thin a bit more than intended.

I want to be honest about the strength here: this is theoretical, based on test-tube work, not real patient cases. Still, since danaparoid is a serious anticoagulant, it's worth watching for easy bruising, nosebleeds, bleeding gums, or unusual bleeding. Please loop in your pharmacist or doctor before adding lion's mane.

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…”
