Drug & supplement interaction

Cilantro + Imiquimod

Imiquimod brand names: Aldara, Zyclara, Vyloma.

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 Cilantro and Imiquimod 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

Cilantro and Imiquimod

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 Imiquimod and Cilantro 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.

Cilantro safety at a glance

Cilantro overall Generally safe Cilantro is generally safe when eaten as a food, but concentrated supplements are less studied.
Pregnancy Use caution Food amounts are likely fine, but medicinal or supplement doses lack safety data and should be avoided.
Breastfeeding Use caution Food amounts are likely fine, but there is not enough information on concentrated supplements.

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

How we checked

Why No Interaction Is Listed for Imiquimod

Interactions in our licensed database are recorded against drug classes, not just single drug names. Imiquimod is filed under a single classification — topical drugs. Cilantro has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and photosensitizing drugs (moderate) — and none of Imiquimod’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 to actually watch for

No Interaction Found — But Data Suggests Cilantro and Imiquimod 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.

Everything else you take

See Every Supplement That Interacts With Imiquimod

This page covers Cilantro only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Imiquimod page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Dimethylsulfoxide (dmso) (moderate), Turpentine Oil (moderate) and Alchemilla (minor).

By severity: 2 moderate · 1 minor.

From our pharmacist’s overview on the Imiquimod page

“Imiquimod (Aldara, Zyclara, Vyloma) is a cream for warts, precancerous spots, and certain skin cancers, and its supplement list is short and workable for most people. Only 3 ingredients are on file, none rated major, and all involve products applied to the skin rather than swallowed.”

About Cilantro

What is Cilantro?

  • Digestive upset and bloating
  • Antimicrobial support
  • Antioxidant support
  • Heavy metal 'detox' (chelation) claims
  • Culinary flavoring

Cilantro is the leafy part of the Coriandrum sativum plant and is widely eaten as a food, where it is considered safe for most people. While it has antioxidant and antimicrobial properties in lab studies, strong human evidence for any specific health benefit is lacking, and popular 'detox' claims are not well supported. Talk with your pharmacist or doctor before using concentrated cilantro supplements or essential oil.

Coriandrum sativum · Apiaceae · Leaves, stems, seeds (coriander), and essential oil · Fresh herb, dried herb, seeds, capsules, extracts, essential oil, tea

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

Cilantro: dosing

There is no standardized medicinal dose for cilantro. As a food, it is simply used to taste in cooking, which is considered safe for most people.For supplements such as capsules, extracts, or teas, follow the directions on the product label, since strengths vary widely between products. Essential oil is highly concentrated and should not be taken by mouth unless directed by a qualified professional.

What Is Imiquimod Topical Used For?

Imiquimod cream is used to treat three skin conditions in adults: actinic keratoses (rough, scaly patches on the skin caused by sun damage) on the face or scalp; superficial basal cell carcinoma (a type of skin cancer) on the trunk, neck, or limbs when surgery is not the best option; and external genital and perianal warts (condyloma acuminata) in patients 12 years and older.

It is not effective for molluscum contagiosum in children ages 2–12, and it has not been proven safe or effective in people with weakened immune systems. It should not be used for warts inside the urethra, vagina, cervix, rectum, or anal canal.

Taking Cilantro and Imiquimod Together: Common Questions

Is it safe to take Cilantro with Imiquimod?
We do not list a known interaction between Cilantro and Imiquimod. 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 Cilantro and Imiquimod have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
How was the Cilantro and Imiquimod combination checked?
Interactions in our licensed database are recorded against drug classes. Imiquimod is filed under 1 classification, and Cilantro has documented interactions with 2 drug classes — none of Imiquimod'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 Cilantro interact with any other medications?
Yes. Cilantro has 434 documented drug interactions in our database — Imiquimod 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 Imiquimod interact with any supplements?
Yes. Imiquimod has documented interactions with 3 supplements in our database — Cilantro is not one of them. The Imiquimod interaction page linked on this page lists every one, ranked by severity.
