Jequirity and Acetylsalicylic acid

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Acetylsalicylic acid

Acetylsalicylic acid falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Jequirity interacts with.

Evidence from in vitro research suggests that constituents of jequirity beans can inhibit platelet aggregation. Theoretically, jequirity 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Before anything else, please know that jequirity seeds are genuinely poisonous. They contain abrin, a toxin in the same family as ricin, and there is no safe supplement dose. You should not be taking this at all, no matter what other medicines you're on.

Now, to your actual question: aspirin already thins the blood by blocking platelets from clumping together. Lab studies hint that compounds in jequirity may do something similar. So in theory, combining the two could stack their effects and raise your bleeding risk, think easy bruising, nosebleeds, bleeding gums, or stomach bleeding. I want to be honest that this is theoretical and based only on test-tube research, not real patient cases. The bigger danger here is the seed's toxicity. Please talk with your pharmacist or doctor.

From our pharmacist’s overview on the Acetylsalicylic acid page

“Acetylsalicylic acid (aspirin, sold as Entrophen) thins the blood by design, which is exactly why this page earns real vigilance rather than a quick skim. Of the 242 supplement and herbal ingredients on file, more than 200 can add to that blood-thinning effect and raise the chance of bruising or bleeding, especially in the stomach.”
