Aromatherapy + Lisinopril

Lisinopril brand names: Zestril, Prinivil, Qbrelis.

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 Aromatherapy and Lisinopril 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.

Interaction report

Aromatherapy and Lisinopril

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 Lisinopril and Aromatherapy 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 Aromatherapy at all — not against Lisinopril, 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.

Aromatherapy safety at a glance

Aromatherapy overall Use caution Generally low-risk when inhaled, but essential oils are concentrated and can irritate skin or be toxic if swallowed.
Pregnancy Possibly Unsafe When used orally. Some essential oils can cause severe side effects, including convulsions and kidney failure, when ingested in large amounts. Read the full pregnancy detail
Breastfeeding Use caution Safety is not well studied, so use cautiously and avoid applying oils near the breast or baby.

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.

What to actually watch for

No Interaction Found — But Data Suggests Aromatherapy and Lisinopril 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. 5 of them are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on Additional detail

    Aromatherapy

    “Ingestion of undiluted oils can sometimes result in significant adverse events including convulsions, particularly in children (8,12,19). Essential oils with proconvulsant effects include rosemary oil, eucalyptus, camphor, fennel oil, hyssop oil, pennyroyal, sage oil, cedar, and thuja. Ingestion of camphorated oil 5-30 mL by children 5 years and younger has resulted in twitch, seizure, ataxia, and coma.”

Reported for Aromatherapy but not commonly for Lisinopril: seizures.

Effects for Lisinopril come from the ADVERSE REACTIONS section of its FDA label; effects for Aromatherapy come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 313,746 voluntary FDA FAERS reports for Lisinopril 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.

Overlapping uses

What Lisinopril Is Prescribed For, and What Aromatherapy Has Been Studied For

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

Lisinopril is prescribed for: Lisinopril treats high blood pressure (hypertension) in adults and children 6 years and older, and can be used alone or alongside other blood pressure medicines. Lowering blood pressure reduces the risk of strokes and heart attacks. The tablet combination product containing lisinopril and hydrochlorothiazide is specifically indicated for high blood pressure. Lisinopril is also used as an add-on therapy to reduce signs and symptoms of systolic heart failure, and to reduce the risk of death in people who are hemodynamically stable (have reasonably stable circulation) within 24 hours of an acute heart attack (acute myocardial infarction).

Aromatherapy has been studied for:

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

    Aromatherapy for stroke

    Although there is interest in using inhaled aromatherapy for hemiplegic shoulder pain in stroke patients, there is insufficient reliable information about the clinical effects of aromatherapy for this condition.

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 Lisinopril on your own; if you are taking Aromatherapy for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Aromatherapy

What is Aromatherapy?

Aromatherapy
  • Stress and relaxation
  • Anxiety
  • Sleep problems
  • Nausea
  • Headaches
  • Mood support

Aromatherapy uses scented essential oils, usually inhaled or applied to the skin, to support relaxation and well-being. Some studies suggest it may modestly help with stress, anxiety, and nausea, but evidence is limited and it should not replace medical treatment. When used carefully, it is generally low-risk, but essential oils are concentrated and can irritate skin or cause harm if swallowed.

Essential oils distilled or pressed from various plants (flowers, leaves, bark, peel, roots) · Essential oils for diffusers, inhalers, topical blends, massage oils, bath products

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

Aromatherapy: dosing

There is no standardized dose for aromatherapy. The amount used depends on the type of oil, the product, and how it is being used (diffuser, inhaler, skin, or bath).A good general rule is to use the smallest amount that gives the effect you want, and to follow the directions on the product label. When applying oils to the skin, always dilute them in a carrier oil first.

Taking Aromatherapy and Lisinopril Together: Common Questions

Is it safe to take Aromatherapy with Lisinopril?
We do not list a known interaction between Aromatherapy and Lisinopril. 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 Aromatherapy and Lisinopril have any of the same side effects?
Yes — our sources link each of them separately to 10 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.
Are Aromatherapy and Lisinopril 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 Aromatherapy in each. That is a conversation for your prescriber, especially if Lisinopril is being adjusted to a target.
Does Lisinopril interact with any supplements?
Yes. Lisinopril has documented interactions with 167 supplements in our database — Aromatherapy is not one of them. The Lisinopril interaction page linked on this page lists every one, ranked by severity.
