Drug & supplement interaction

Chrysanthemum + Nadolol

Nadolol brand names: Corgard, Nadolol.

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 Chrysanthemum and Nadolol 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.

Chrysanthemum and Nadolol

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 Nadolol and Chrysanthemum 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Chrysanthemum at all — not against Nadolol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Chrysanthemum safety at a glance

Chrysanthemum overall Use caution Generally well tolerated as a tea, but it can cause allergic reactions in sensitive people.
Pregnancy Avoid Safety during pregnancy has not been established, so it is best avoided unless your doctor approves.
Breastfeeding Avoid There is not enough reliable information on safety while breastfeeding, so caution or avoidance is wise.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests Chrysanthemum and Nadolol 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. One of them is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    Chrysanthemum

    “Topically and via occupational exposure, chrysanthemum can cause allergic reactions. Chrysanthemum allergy symptoms can include urticaria, contact dermatitis, eczema, actinic reticuloid photosensitivity dermatitis, pollinosis, rhinoconjunctivitis, and asthma. There are numerous case reports and studies showing that allergies to Chrysanthemum are very common, with an estimated 60% of Europeans being allergic.”

    Recorded for Chrysanthemum in the same Natural Medicines adverse-effect record shown under Wheezing above.

    Nadolol

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

Reported for Chrysanthemum but not commonly for Nadolol: an allergic reaction, sun sensitivity and hives.

Effects for Nadolol come from the ADVERSE REACTIONS section of its FDA label; effects for Chrysanthemum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,530 voluntary FDA FAERS reports for Nadolol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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 Nadolol Is Prescribed For, and What Chrysanthemum Has Been Studied For

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

Nadolol is prescribed for: Nadolol tablets are used for two main conditions: high blood pressure (hypertension) and angina pectoris (ongoing chest pain caused by reduced blood flow to the heart). Lowering high blood pressure reduces the risk of stroke and heart attack. For high blood pressure, nadolol may be prescribed on its own or combined with other blood pressure medications, especially thiazide-type diuretics (water pills). For angina, it is used for long-term management to help reduce how often chest pain occurs.

Chrysanthemum has been studied for:

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

    Chrysanthemum for angina

    Although there has been interest in using oral chrysanthemum for angina, there is insufficient reliable information about the clinical effects of chrysanthemum for this purpose.

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

    Chrysanthemum for stroke

    It is unclear if oral chrysanthemum is beneficial in patients with stroke.

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

    Chrysanthemum for hypertension

    Although there has been interest in using oral chrysanthemum for hypertension, there is insufficient reliable information about the clinical effects of chrysanthemum for this purpose.

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 Nadolol on your own; if you are taking Chrysanthemum for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Nadolol

This page covers Chrysanthemum only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nadolol page lists 145 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Green Tea (major) and Indian Snakeroot (major).

By severity: 6 major · 119 moderate · 20 minor.

From our pharmacist’s overview on the Nadolol page

“If you take nadolol (Corgard) for blood pressure, angina, or heart rhythm, treat this list with real care, and green tea is the surprise at the top. In a clinical study, green tea cut nadolol blood levels by roughly 85 percent, which can quietly leave you undertreated.”

About Chrysanthemum

What is Chrysanthemum?

  • Eye irritation and tired eyes
  • Cooling and 'heat-clearing' in traditional Chinese medicine
  • Cold and flu symptoms
  • Headache
  • Soothing/relaxation
  • High blood pressure (traditional use)

Chrysanthemum flowers are most often used as a soothing tea in traditional Chinese medicine and as a folk remedy for eye irritation, colds, and minor inflammation. Solid human evidence for these uses is limited, so it should be seen as a pleasant traditional drink rather than a proven treatment. People allergic to ragweed and related plants, and those who are pregnant or breastfeeding, should be cautious and talk to a pharmacist or doctor first.

Chrysanthemum morifolium · Asteraceae · Flowers (dried flower heads) · Tea, dried flowers, capsules, extracts, topical preparations

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

Chrysanthemum: dosing

There is no official standardized dose for chrysanthemum. It is most often used as a tea made from dried flowers, and supplement strength varies widely between products.If you choose to use it, follow the directions on the product label and start with a small amount to see how you react.

Taking Chrysanthemum and Nadolol Together: Common Questions

Is it safe to take Chrysanthemum with Nadolol?
We do not list a known interaction between Chrysanthemum and Nadolol. 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 Chrysanthemum and Nadolol 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.
Are Chrysanthemum and Nadolol 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 Chrysanthemum in each. That is a conversation for your prescriber, especially if Nadolol is being adjusted to a target.
Does Nadolol interact with any supplements?
Yes. Nadolol has documented interactions with 145 supplements in our database — Chrysanthemum is not one of them. The Nadolol interaction page linked on this page lists every one, ranked by severity.
