What is this page for?

First and foremost: how Lovage interacts with medications. The heart of this page is the interaction list — every drug Lovage is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Lovage is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Lovage Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Lovage drug interaction appears low for most people. None of the listed interactions are rated major, and every one rests on theory rather than documented effects in people.

Interactions deserving the most attention

The one group that stands out is diuretics, often called water pills, such as furosemide and hydrochlorothiazide. Lovage root may make the body pass more water on its own, so in theory it could interfere with how well these medicines control fluid balance or blood pressure. This concern comes from the herb's known properties, not from reported problems in people, so we see it as a reason for awareness rather than alarm if you take a diuretic.

What the rest of the list means

Although lovage appears alongside a fairly long list of medications, nearly all of that list traces back to this single theoretical concern with water pills. A predicted interaction on paper does not mean harm has actually been seen, and no interaction here has been confirmed in human studies.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
Each drug listed above links to the full report for that exact Lovage combination — clinical detail, likelihood, evidence level, and citations.

Lovage: Uses, Safety & Side Effects

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Reviewed July 2026 ·

The bottom line

Lovage is a celery-like herb traditionally used for digestion, bloating, and as a mild diuretic to flush the urinary tract. Human evidence for these uses is very limited, and while culinary amounts are generally well tolerated, concentrated supplements and the essential oil should be used cautiously. Pregnant and breastfeeding people should avoid it.

Overview

Lovage (Levisticum officinale) is a tall, leafy herb in the same plant family as celery, carrots, and parsley. It has a strong celery-like smell and taste, and its leaves, stalks, seeds, and roots have long been used in cooking across Europe and parts of Asia.

Beyond the kitchen, lovage has a long history in traditional herbal medicine. People have used the root and leaves as a tea or extract for digestive complaints, bloating, and to encourage urine flow. The plant grows well in temperate climates and is often found in herb gardens.

How it works

Lovage contains aromatic compounds in its essential oil, including phthalides (such as ligustilide), along with plant chemicals like coumarins, flavonoids, and volatile oils. These give the herb its distinctive smell and are thought to relax smooth muscle in the gut and increase urine flow.

In laboratory and animal studies, some lovage extracts have shown mild antispasmodic, diuretic, and antimicrobial activity. These effects, however, have not been clearly confirmed in well-designed human trials, so the proposed mechanisms remain largely theoretical.

This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.

Safety & precautions

As a food and seasoning, lovage is generally well tolerated. Concentrated supplements, tinctures, and especially the essential oil are stronger and have less safety information available, so they should be used carefully.

Because lovage can act as a diuretic, people with kidney disease or heart conditions should talk to a doctor first. Some people in the carrot/celery family are allergic to lovage. The plant also contains coumarins and compounds that can make the skin more sensitive to sunlight (photosensitivity), particularly with the essential oil.

Pregnancy: Avoid lovage. It has traditionally been used to stimulate menstrual flow and may affect the uterus, which could be risky in pregnancy. Breastfeeding: Avoid it as well, since there is not enough information to confirm it is safe. Always check with a pharmacist or doctor before using lovage supplements.

Side effects

When used in food amounts, lovage rarely causes problems. Larger or concentrated doses may cause stomach upset or increased urination. Because it can increase sensitivity to sunlight, some people may get a skin rash or sunburn more easily after using it, especially with the essential oil.

Allergic reactions are possible, particularly in people allergic to celery, carrot, parsley, or other plants in the same family. Stop using lovage and seek medical care if you have swelling, trouble breathing, or a severe rash.

Lovage: Reported Adverse Effects

Documented safety reports on Lovage from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

A high-quality assessment of the adverse effects of lovage has not been conducted. However, long-term oral use of lovage may result in an increased risk of phototoxic reactions, including photosensitivity. Topical exposure may also result in photosensitivity or contact dermatitis.

Reports by condition

Dermatitis Dermatologic

Orally, long-term use of lovage may result in an increased risk of phototoxic reactions, including photosensitivity. Avoid excessive exposure to the sun or UV light if using lovage. A case of contact dermatitis has been reported in a 31-year-old female who applied undiluted lovage essential oil to the skin for 2 weeks. The skin healed after receiving topical and systemic steroids. A case of photosensitivity has also been reported secondary to harvesting lovage.

Dosing

There is no well-established or standardized dose of lovage for any health condition. Traditional preparations include teas made from the dried root or leaves, capsules, and tinctures, with amounts varying widely by product.

The best approach is to follow the directions on the product label and not exceed the recommended amount. The essential oil is very concentrated and should not be taken by mouth without professional guidance. Talk to a pharmacist or doctor before starting lovage, especially if you take other medicines or have a health condition.

Lovage: Common Questions

What is Lovage used for, and does it work?

People use Lovage for a range of reasons, but according to the Natural Medicines database the current clinical evidence is insufficient to confirm it works for the specific conditions it has been studied for. See the graded list on this page, and talk to your pharmacist or doctor before relying on it for any condition.

Does Lovage interact with prescription medications?

Yes. We list 75 medications with a known interaction with Lovage. Use the checker above to see how Lovage interacts with a specific drug.

How are Lovage interactions rated?

Each interaction is graded major, moderate, or minor based on how clinically significant it is and the strength of the evidence behind it. Major interactions are the most serious and are best avoided, or used only under close professional supervision.

Is it safe to take Lovage with my medications?

It depends on the specific medication. Some combinations are fine, while others call for monitoring, timing changes, or should be avoided. Check your exact drug above and confirm with your pharmacist or doctor before starting, stopping, or changing anything.

Where does this Lovage interaction information come from?

Our interaction data is built on the Natural Medicines database — an evidence-graded reference for vitamins, herbs, and supplements — and is reviewed by licensed HelloPharmacist pharmacists, who may add clinical context.

What is Lovage used for?

People mainly use Lovage for digestive complaints like gas and bloating, as a mild diuretic to flush the urinary tract, and as a celery-like flavoring in cooking. Strong scientific proof for its medicinal uses is lacking.

Is Lovage safe to take?

In food amounts it is generally well tolerated. Concentrated supplements and the essential oil have limited safety data and should be used cautiously, especially if you have kidney problems or allergies to celery-family plants.

Can I use Lovage if I am pregnant or breastfeeding?

No. Lovage is traditionally avoided in pregnancy because it may affect the uterus and menstrual flow, and there is not enough information to consider it safe while breastfeeding.

Does Lovage make you urinate more?

Lovage has been used as a mild diuretic, meaning it may increase urine output. If you have heart or kidney conditions, check with your doctor before using it for this purpose.
