Mormon Tea + 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 Mormon Tea 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.

Mormon Tea 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 Mormon Tea 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 Mormon Tea 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.

Mormon Tea safety at a glance

Mormon Tea overall Use caution Generally considered milder than Asian ephedra, but human safety data are limited.
Pregnancy Avoid Not enough safety information, and ephedra-related plants are best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid use while breastfeeding.

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

No Interaction Found — But Data Suggests Mormon Tea 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.

  • Stomach upset / Constipation Additional detail

    Nadolol

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

Effects for Nadolol come from the ADVERSE REACTIONS section of its FDA label; effects for Mormon Tea 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.

See Every Supplement That Interacts With Nadolol

This page covers Mormon Tea 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 Mormon Tea

What is Mormon Tea?

  • Caffeine-free beverage
  • Kidney and urinary complaints
  • Cold and congestion relief
  • Mild digestive upset
  • General tonic

Mormon Tea is a traditional Southwestern desert beverage made from a North American Ephedra plant that, unlike Asian ephedra, is generally thought to lack ephedrine. There is very little modern scientific evidence to support any specific health benefit, so it is mostly used as a mild, caffeine-free herbal drink. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a medical condition.

Ephedra nevadensis · Ephedraceae · Dried stems and twigs · Tea (dried herb), capsules, loose dried stems

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

Mormon Tea: dosing

There is no established standardized dose for Mormon Tea. Traditionally, a small amount of dried stems is steeped in hot water and drunk as a tea, but the strength of homemade or commercial products can vary widely.If you choose to use it, follow the directions on the product label and do not exceed them. Because the active content is uncertain, start low and avoid frequent or large amounts.

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 Mormon Tea and Nadolol Together: Common Questions

Is it safe to take Mormon Tea with Nadolol?
We do not list a known interaction between Mormon Tea 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 Mormon Tea 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.
Does Nadolol interact with any supplements?
Yes. Nadolol has documented interactions with 145 supplements in our database — Mormon Tea is not one of them. The Nadolol interaction page linked on this page lists every one, ranked by severity.
