Tree Turmeric 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 Tree Turmeric interacts with.

Theoretically, tree turmeric might have additive effects when used with anticoagulant and antiplatelet drugs and increase the risk of bleeding.
In vitro and animal research suggest that berberine, a constituent of tree turmeric, 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

Here's the simple version: aspirin already works by making your platelets less sticky, which is how it helps prevent clots. Tree turmeric (through its berberine content) may do a little of that same thing. So when you take them together, the worry is that their effects could stack up and make you bleed or bruise more easily than aspirin alone would.

I want to be honest about how strong this concern is. Right now it's theoretical, based only on lab and animal studies, not real patient data. That doesn't mean ignore it. Just watch for things like easy bruising, nosebleeds, bleeding gums, or dark stools, and let your doctor or pharmacist know before you add a concentrated berberine supplement, especially if you take aspirin daily.

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.”
