No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Angelica Archangelica and Timolol 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

Angelica Archangelica and Timolol

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 Timolol and Angelica Archangelica 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 Timolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Timolol is filed under 5 classifications — including beta-blockers, antihypertensive drugs, cytochrome p450 2d6 (cyp2d6) substrates. Angelica Archangelica has documented interactions with 1 drug class — the most serious being photosensitizing drugs (moderate) — and none of Timolol’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.

What to actually watch for

No Interaction Found — But Data Suggests Angelica Archangelica and Timolol May Share a Side Effect

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.

  • A skin rash Additional detail

    Angelica Archangelica

    “Orally or topically, Angelica archangelica might cause photosensitivity reactions. Patients who take Angelica archangelica orally or apply it topically should be advised to avoid prolonged exposure to the sun. Some constituents of the leaves have a strong irritant effect on the skin and mucous membranes, referred to as "angelica dermatitis" (18).”

    Timolol

    Listed in the ADVERSE REACTIONS section of the FDA label for Timolol. Read the label on DailyMed ›

Reported for Angelica Archangelica but not commonly for Timolol: sun sensitivity and constipation.

Effects for Timolol come from the ADVERSE REACTIONS section of its FDA label; effects for Angelica Archangelica come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Timolol Is Prescribed For, and What Angelica Archangelica Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Timolol is a prescription medicine with approved uses on its FDA label. Angelica Archangelica is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Timolol is prescribed for: Timolol eye drops lower raised pressure inside the eye in people with ocular hypertension or open-angle glaucoma. This is the use for every eye product listed, including Timoptic, Timoptic-XE, Istalol, Betimol and Timolol GFS. Timolol Maleate tablets (taken by mouth) have different uses. They treat high blood pressure, reduce the risk of death and repeat heart attack in stable patients who have survived the acute phase of a heart attack, and help prevent migraine headaches.

Angelica Archangelica has been studied for:

  • Stroke studied, not established Angelica Archangelica has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Angelica Archangelica for stroke

    Although there has been interest in using oral Angelica archangelica for stroke, there is insufficient reliable information about the clinical effects of Angelica archangelica for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Timolol on your own; if you are taking Angelica Archangelica for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Timolol page

“The supplement list for timolol (Blocadren, Timoptic) calls for genuine care, starting with its five major-rated entries. Timolol is a beta-blocker that slows the heart and lowers blood pressure, and even the eye-drop form absorbs enough to matter.”

About Angelica Archangelica

What is Angelica Archangelica?

Angelica Archangelica
  • Digestive upset and gas
  • Loss of appetite
  • Anxiety and restlessness
  • Mild respiratory complaints
  • Flavoring in foods and drinks

Angelica archangelica is a tall aromatic herb used traditionally for digestive complaints, poor appetite, and to flavor foods and liqueurs. Solid human evidence for its health benefits is limited, and its skin-sensitizing furanocoumarins mean caution is warranted. Pregnant and breastfeeding people should avoid it, and anyone considering it should check with a pharmacist or doctor first.

Angelica archangelica · Apiaceae (Umbelliferae) · Root, seeds (fruit), leaves, and essential oil · Tea, dried root, tincture, capsules, essential oil, and as a flavoring in liqueurs

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

Angelica Archangelica: dosing

There is no well-established standardized dose for Angelica archangelica. Traditional preparations include teas made from the dried root or seeds, tinctures, and capsules, but the amount of active compounds can vary widely between products.Because reliable dosing guidelines are lacking, the safest approach is to follow the directions on the product label and not exceed them. Avoid combining it with strong sun exposure or tanning.

Taking Angelica Archangelica and Timolol Together: Common Questions

Is it safe to take Angelica Archangelica with Timolol?
We do not list a known interaction between Angelica Archangelica and Timolol. 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 Angelica Archangelica and Timolol have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Are Angelica Archangelica and Timolol used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Angelica Archangelica in each. That is a conversation for your prescriber, especially if Timolol is being adjusted to a target.
How was the Angelica Archangelica and Timolol combination checked?
Interactions in our licensed database are recorded against drug classes. Timolol is filed under 5 classifications, and Angelica Archangelica has documented interactions with 1 drug class — none of Timolol'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 Angelica Archangelica interact with any other medications?
Yes. Angelica Archangelica has 335 documented drug interactions in our database — Timolol 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 Timolol interact with any supplements?
Yes. Timolol has documented interactions with 183 supplements in our database — Angelica Archangelica is not one of them. The Timolol interaction page linked on this page lists every one, ranked by severity.
