The bottom line No known interaction

We found no known interaction between Motherwort and Propranolol 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.

Motherwort and Propranolol

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 Propranolol and Motherwort 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.

Motherwort safety at a glance

Motherwort overall Use caution May be tolerated short-term by healthy adults, but human safety data are limited.
Pregnancy Likely Unsafe When used orally or by injection. Alkaloids present in motherwort have uterine stimulant effects. Read the full pregnancy detail
Breastfeeding Avoid Not enough safety information is available, so it is best avoided.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Propranolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Propranolol is filed under 9 classifications — including beta-blockers, cytochrome p450 2c19 (cyp2c19) substrates, antihypertensive drugs. Motherwort has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Propranolol’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.

Overlapping uses

What Propranolol Is Prescribed For, and What Motherwort Has Been Studied For

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

Propranolol is prescribed for: This intravenous (IV) form of propranolol is used in hospital or clinical settings to treat dangerous heart rhythm problems. It is generally reserved for life-threatening arrhythmias (abnormal heart rhythms) or those that occur during anesthesia. Specific conditions it treats include fast heart rates coming from the upper chambers of the heart (supraventricular tachycardia), certain arrhythmias caused by digitalis toxicity, dangerous ventricular rhythms that haven't responded to other treatments, and fast heart rates caused by excess adrenaline-like substances during surgery.

Motherwort has been studied for:

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

    Motherwort for heart failure

    Although there has been interest in using oral motherwort for heart failure, there is insufficient reliable information about the clinical effects of motherwort 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 Propranolol on your own; if you are taking Motherwort for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Propranolol

This page covers Motherwort only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Propranolol page lists 236 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), Indian Snakeroot (major) and Tyramine (major).

By severity: 5 major · 194 moderate · 37 minor.

From our pharmacist’s overview on the Propranolol page

“Propranolol (Inderal) slows the heart and lowers blood pressure, which is exactly why its 236-ingredient interaction list deserves genuine care. Five entries rate major, and those are the ones to understand first.”

About Motherwort

What is Motherwort?

Motherwort
  • Anxiety and stress
  • Heart palpitations
  • Menstrual discomfort
  • Menopausal symptoms
  • Insomnia

Motherwort is a traditional herb in the mint family long used for anxiety, heart palpitations, and women's reproductive complaints, but solid human evidence is very limited. It should be avoided during pregnancy and breastfeeding, and anyone with a heart condition or taking heart or blood-thinning medicines should talk to a doctor or pharmacist before using it.

Leonurus cardiaca · Lamiaceae · Aerial parts (leaves, stems, and flowering tops) · Tea, tincture, liquid extract, capsules, dried herb

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

Motherwort: dosing

There is no well-established standard dose for motherwort. Traditional preparations include teas made from the dried herb and liquid tinctures or extracts, and products vary widely in strength.Because doses are not standardized and product quality differs, the safest approach is to follow the directions on the specific product label and not exceed the suggested amount.

Taking Motherwort and Propranolol Together: Common Questions

Is it safe to take Motherwort with Propranolol?
We do not list a known interaction between Motherwort and Propranolol. 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.
Are Motherwort and Propranolol 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 Motherwort in each. That is a conversation for your prescriber, especially if Propranolol is being adjusted to a target.
How was the Motherwort and Propranolol combination checked?
Interactions in our licensed database are recorded against drug classes. Propranolol is filed under 9 classifications, and Motherwort has documented interactions with 1 drug class — none of Propranolol'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 Motherwort interact with any other medications?
Yes. Motherwort has 248 documented drug interactions in our database — Propranolol 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 Propranolol interact with any supplements?
Yes. Propranolol has documented interactions with 236 supplements in our database — Motherwort is not one of them. The Propranolol interaction page linked on this page lists every one, ranked by severity.
