Tree Of Heaven and Ticagrelor

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ticagrelor

Ticagrelor falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Tree Of Heaven interacts with.

Theoretically, tree of heaven extract might reduce platelet aggregation and increase the risk of bleeding if used with antiplatelet or anticoagulant drugs. In vitro evidence shows that tree of heaven crude extract attenuates epinephrine and adenosine diphosphate-induced platelet aggregation. This interaction has not been seen in humans. Until more is known, use with caution in patients taking anticoagulant or antiplatelet drugs.
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: Ticagrelor (Brilinta) already works hard to keep your platelets from clumping together, which is exactly how it protects you after a heart attack, stent, or stroke. In lab dishes, tree of heaven extract also seemed to make platelets less sticky. So the worry is that stacking the two could nudge you toward easier bruising, nosebleeds, bleeding gums, or bleeding that takes longer to stop.

The reassuring part is that this is only a theory based on test-tube studies. It has not been shown to happen in real people, so I wouldn't panic. Still, because bleeding risk is serious, please loop in your pharmacist or doctor before adding tree of heaven, and don't change your Brilinta on your own.

See Every Supplement That Interacts With Ticagrelor

This page covers Tree Of Heaven only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ticagrelor page lists 286 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 241 moderate · 40 minor.

From our pharmacist’s overview on the Ticagrelor page

“Grapefruit sits at the top of this list for good reason. Ticagrelor (Brilinta) is cleared by the CYP3A4 enzyme, and grapefruit blocks that enzyme, so drug levels can climb and bleeding becomes more likely.”

About Tree Of Heaven

What is Tree Of Heaven?

  • Skin conditions (topical, traditional use)

Tree of Heaven (Ailanthus altissima) is a fast-growing, invasive tree whose bark has been used in traditional medicine, mostly for digestive complaints and parasites. Modern scientific evidence in humans is very limited, and the plant can cause stomach upset and skin reactions, so it should be used cautiously and not without professional guidance.

About Ticagrelor

What Is Ticagrelor Used For?

Brand name: Brilinta

Ticagrelor tablets are used to lower the risk of cardiovascular death, heart attack (myocardial infarction), and stroke in adults who have had acute coronary syndrome (ACS) — a group of conditions including unstable angina and heart attack — or who have a history of heart attack. It also reduces the risk of stent thrombosis (a blood clot forming in a coronary stent) in people who have been stented for ACS treatment.

Ticagrelor tablets are also used in people with coronary artery disease (CAD) who are at high risk for a first heart attack or stroke, particularly those with type 2 diabetes. Additionally, Brilinta is approved to reduce the risk of stroke in adults with a mild acute ischemic stroke or a high-risk transient ischemic attack (TIA, or "mini-stroke").
