No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Pheasant's Eye and Ticagrelor in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Pheasant's Eye and Ticagrelor

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Ticagrelor and Pheasant's Eye in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Ticagrelor

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ticagrelor is filed under 5 classifications — including anticoagulant/antiplatelet drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates. Pheasant's Eye has documented interactions with 7 drug classes — the most serious being digoxin (lanoxin) (major), corticosteroids (moderate) and diuretic drugs (moderate) — and none of Ticagrelor’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Pheasant's Eye and Ticagrelor May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

See Every Supplement That Interacts With Ticagrelor

This page covers Pheasant's Eye 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 Pheasant's Eye

What is Pheasant's Eye?

  • Heart failure symptoms
  • Irregular or weak heartbeat
  • Fluid retention (as a diuretic)
  • Nervous heart complaints
  • Mild anxiety with heart palpitations

Pheasant's Eye (Adonis vernalis) is a toxic plant that contains heart-acting compounds similar to those in foxglove. It has been used in traditional and old European medicine for heart problems, but it is poisonous and has a very narrow margin of safety. You should not use it on your own — it should only ever be considered under direct medical supervision, if at all.

Adonis vernalis · Ranunculaceae · Dried above-ground parts (herb), including flowers, stems, and leaves · Tincture, dried herb extract, and standardized preparations (historically); rarely available as a non-prescription supplement

An interaction check asks whether these two react with each other — it does not ask whether Pheasant's Eye is a good idea for someone in your situation. Here is what our Pheasant's Eye record says about it on its own.

Pheasant's Eye: dosing

There is no safe, established over-the-counter dose for Pheasant's Eye, and we will not suggest one. Because the plant is toxic and the gap between an active dose and a poisonous dose is very small, dosing was historically left to trained practitioners using standardized, carefully measured preparations.We do not recommend using this plant on your own. If a product containing it is ever offered to you, do not take it without first speaking to a doctor or pharmacist. Always follow professional medical guidance rather than a product label alone.

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").

Taking Pheasant's Eye and Ticagrelor Together: Common Questions

Is it safe to take Pheasant's Eye with Ticagrelor?
We do not list a known interaction between Pheasant's Eye and Ticagrelor. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Pheasant's Eye and Ticagrelor have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Pheasant's Eye and Ticagrelor combination checked?
Interactions in our licensed database are recorded against drug classes. Ticagrelor is filed under 5 classifications, and Pheasant's Eye has documented interactions with 7 drug classes — none of Ticagrelor's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Pheasant's Eye interact with any other medications?
Yes. Pheasant's Eye has 156 documented drug interactions in our database — Ticagrelor is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Ticagrelor interact with any supplements?
Yes. Ticagrelor has documented interactions with 286 supplements in our database — Pheasant's Eye is not one of them. The Ticagrelor interaction page linked on this page lists every one, ranked by severity.
