The bottom line No known interaction

We found no known interaction between Lemon Verbena and Verapamil 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.

Lemon Verbena and Verapamil

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 Verapamil and Lemon Verbena 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.

Lemon Verbena safety at a glance

Lemon Verbena overall Use caution Generally well tolerated as a tea or food, but concentrated extracts and the essential oil are less studied.
Pregnancy Avoid Not enough safety data, so it is best avoided in medicinal amounts during pregnancy.
Breastfeeding Avoid Safety has not been established, so avoid medicinal amounts while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Verapamil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Verapamil is filed under 11 classifications — including calcium channel blockers, cytochrome p450 2c8 (cyp2c8) substrates, cytochrome p450 3a4 (cyp3a4) inhibitors. Lemon Verbena has documented interactions with 1 drug class — the most serious being benzodiazepines (moderate) — and none of Verapamil’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 Lemon Verbena Itself Has Been Linked To

This is not an interaction — nothing below involves Verapamil. It is the side-effect record for Lemon Verbena on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Lemon Verbena, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Lemon Verbena — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Verapamil’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Verapamil column appears here.

From our pharmacist’s overview on the Verapamil page

“This is one of the longer interaction lists we publish, and with verapamil (Calan, Verelan) it warrants genuine care, starting with the ten major-rated entries. Verapamil lowers blood pressure and slows the heart, so most of the 295 ingredients on file either push that effect further than intended or change how much of the drug reaches…”

About Lemon Verbena

What is Lemon Verbena?

Lemon Verbena
  • Digestive upset
  • Anxiety and trouble sleeping
  • Joint pain and inflammation
  • Exercise recovery and oxidative stress
  • Weight management
  • Flavoring and aromatherapy

Lemon verbena is a fragrant South American herb most often enjoyed as a tea or flavoring, and it contains polyphenols like verbascoside that have antioxidant activity in lab studies. Some small studies hint at benefits for inflammation, exercise recovery, and appetite, but the human evidence is limited and far from proven. It is generally well tolerated as a food and tea, but talk with your pharmacist or doctor before using concentrated supplements, and avoid it during pregnancy and breastfeeding.

Aloysia citrodora · Verbenaceae · Leaves and flowering tops; the essential oil is also used · Tea, capsules, liquid extracts, essential oil, and as a flavoring in foods and beverages

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

Lemon Verbena: dosing

There is no official or well-established standardized dose for lemon verbena. As a tea, it is commonly prepared by steeping the dried leaves in hot water, similar to other herbal teas.For capsules and extracts, products vary widely and some are standardized to a certain percentage of polyphenols or verbascoside. More is not always better, and starting with the lowest amount is a sensible approach.

About Verapamil

What Is Verapamil Used For?

Brand names: Isoptin SR, Verelan, Isoptin, Calan SR, Verelan SR, Calan, Covera HS, Verap, Veramil

Verapamil tablets and film-coated tablets are used to treat angina — including vasospastic (Prinzmetal's) angina, unstable angina, and chronic stable angina — as well as certain abnormal heart rhythms (arrhythmias) and high blood pressure (essential hypertension). For arrhythmias, regular-release tablets are used alongside digoxin to control heart rate in atrial flutter or atrial fibrillation, and to help prevent episodes of paroxysmal supraventricular tachycardia (SVT), a type of rapid heartbeat.

Extended-release and sustained-release oral forms (tablets and capsules) are indicated specifically for high blood pressure. Verapamil hydrochloride injection is used in hospital settings for rapid conversion of SVT to normal rhythm and for temporary control of fast heart rates in atrial flutter or atrial fibrillation.

Most-Reported Side Effects for Verapamil

From FAERS, the FDA’s public side-effect reporting system (4,297 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
