Holy Basil and Ticlopidine

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ticlopidine

Ticlopidine falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Holy Basil interacts with.

Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal research shows that holy basil seed oil can prolong bleeding time, possibly due to inhibition of platelet aggregation. However, it is not known if this occurs in humans.
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

Ticlopidine already does one big job: it keeps your platelets from clumping together to form clots. That is exactly how it protects you from a stroke. The concern here is that holy basil might do a little of the same thing. In animal studies, holy basil seed oil made bleeding take longer, likely because it also nudges platelets to be less sticky. Stack that on top of ticlopidine and, in theory, you could tip toward easier bruising, nosebleeds, bleeding gums, or cuts that are slow to stop.

I want to be honest about the strength of this, though. We only have lab and animal data, not human proof, so this is more a theoretical caution than a documented problem. Still, since ticlopidine itself can affect blood counts, please check with your pharmacist or doctor before adding holy basil, and watch for any unusual bleeding.

From our pharmacist’s overview on the Ticlopidine page

“Ticlopidine (Ticlid) keeps platelets from clumping to prevent clots, so it already raises bleeding risk on its own, and over 200 of the 221 supplements flagged for it push in that same direction. That stacking effect deserves genuine respect from anyone taking this drug.”

About Ticlopidine

What Is Ticlopidine Used For?

Brand names: Ticlid, Ticlopidine

  • Ticlopidine is used to reduce the risk of stroke in people who have had a stroke or have had warning signs of a stroke and who cannot be treated with aspirin. Ticlopidine is also used along with aspirin to prevent blood clots from forming in coronary stents (metal tubes surgically placed in clogged blood vessels to improve blood flow). It works by preventing platelets (a type of blood cell) from collecting and forming clots.
