No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Traveler's Joy 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.

Traveler's Joy 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 Traveler's Joy 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 Traveler's Joy 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.

No Interaction Found — But Data Suggests Traveler's Joy and Nadolol 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.

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 Traveler's Joy

What is Traveler's Joy?

  • Skin and joint complaints (traditional/folk use)
  • Homeopathic remedy for skin conditions
  • Traditional 'counter-irritant' poultice
  • Bach flower remedy for 'inattentiveness' or daydreaming

Traveler's Joy (Clematis vitalba) is a wild climbing vine that is best known as an ornamental hedge plant, not as a proven medicine. The fresh plant is irritating and can be toxic if eaten, and there is no good scientific evidence it treats any health condition. We do not recommend taking it internally.

Clematis vitalba · Ranunculaceae · Leaves and flowers (occasionally other aerial parts) · Rarely sold as a supplement; sometimes found as a homeopathic preparation or in traditional topical/folk remedies

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

Traveler's Joy: dosing

About Nadolol

What Is Nadolol Used For?

Brand names: Corgard, Nadolol

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.

Most-Reported Side Effects for Nadolol

From FAERS, the FDA’s public side-effect reporting system (7,530 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Macular degeneration 831 reports
Nausea 673 reports
Headache 603 reports
Fatigue 526 reports
Weight decreased 464 reports

Taking Traveler's Joy and Nadolol Together: Common Questions

Is it safe to take Traveler's Joy with Nadolol?

Do Traveler's Joy and Nadolol 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.

Does Nadolol interact with any supplements?
Yes. Nadolol has documented interactions with 145 supplements in our database — Traveler's Joy is not one of them. The Nadolol interaction page linked on this page lists every one, ranked by severity.
