Drug & supplement interaction

Chenopodium Oil + Liothyronine

Liothyronine brand name: Cytomel.

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 Chenopodium Oil and Liothyronine 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

Chenopodium Oil and Liothyronine

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 Liothyronine and Chenopodium Oil 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.

Chenopodium Oil safety at a glance

Chenopodium Oil overall Avoid The oil contains ascaridole, which is toxic and has a narrow margin between an effective and a dangerous dose.
Pregnancy Avoid It may stimulate the uterus and is potentially toxic, so it should not be used during pregnancy.
Breastfeeding Unsafe When used orally due to toxicity. Read the full breastfeeding detail

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 Liothyronine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Liothyronine is filed under 2 classifications — thyroid hormone, oral drugs. Chenopodium Oil has documented interactions with 1 drug class — the most serious being photosensitizing drugs (moderate) — and none of Liothyronine’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 Chenopodium Oil and Liothyronine 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.

See Every Supplement That Interacts With Liothyronine

This page covers Chenopodium Oil only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Liothyronine page lists 38 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Tiratricol (major), Acetyl-l-carnitine (moderate), Alpha-lipoic Acid (moderate) and Ascophyllum Nodosum (moderate).

By severity: 2 major · 26 moderate · 10 minor.

From our pharmacist’s overview on the Liothyronine page

“Liothyronine (Cytomel) is the active thyroid hormone T3, and it does not tolerate interference well. Of the 38 supplements and herbs on file, 21 act on thyroid function itself, some amplifying the hormone and others blunting it, iodine-rich seaweeds able to swing either way.”

About Chenopodium Oil

What is Chenopodium Oil?

Chenopodium Oil
  • Intestinal worms (roundworm, hookworm)
  • Digestive upset and gas
  • Respiratory complaints
  • Skin conditions
  • As a culinary seasoning (epazote leaf)

Chenopodium oil is a strong-smelling essential oil from the epazote plant that was historically used to treat intestinal worms. It contains ascaridole, a compound that is quite toxic, and overdoses have caused serious harm, so it is no longer recommended for internal use. Safer modern deworming medicines exist, so talk with a pharmacist or doctor before using this oil.

Dysphania ambrosioides · Amaranthaceae · Essential oil from the leaves and seeds · Essential oil; sometimes the leaf is used as a tea or culinary herb (epazote)

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

Chenopodium Oil: dosing

There is no safe, established dose of chenopodium oil for any condition, and it is not recommended for self-treatment. For intestinal worms, safer and more effective prescription and over-the-counter medicines are available.

About Liothyronine

What Is Liothyronine Used For?

Brand name: Cytomel

Liothyronine (available as tablets under the brand names Cytomel, Liomny, and Liothyronine Sodium, and as an injection under Liothyronine Sodium and Triostat) is primarily used to treat hypothyroidism (an underactive thyroid) across all its forms — whether the cause is in the thyroid itself, the pituitary gland, or the hypothalamus, and whether it was present at birth or developed over time.

The oral tablets are also used alongside surgery and radioiodine therapy to suppress TSH (thyroid-stimulating hormone) in people with well-differentiated thyroid cancer, and as a diagnostic agent in thyroid suppression tests. Liothyronine sodium injection is specifically indicated for myxedema coma (a life-threatening form of severe hypothyroidism) and may be used in patients who are allergic to thyroid products derived from pork or beef.

Taking Chenopodium Oil and Liothyronine Together: Common Questions

Is it safe to take Chenopodium Oil with Liothyronine?
We do not list a known interaction between Chenopodium Oil and Liothyronine. 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 Chenopodium Oil and Liothyronine have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Chenopodium Oil and Liothyronine combination checked?
Interactions in our licensed database are recorded against drug classes. Liothyronine is filed under 2 classifications, and Chenopodium Oil has documented interactions with 1 drug class — none of Liothyronine'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 Chenopodium Oil interact with any other medications?
Yes. Chenopodium Oil has 335 documented drug interactions in our database — Liothyronine 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 Liothyronine interact with any supplements?
Yes. Liothyronine has documented interactions with 38 supplements in our database — Chenopodium Oil is not one of them. The Liothyronine interaction page linked on this page lists every one, ranked by severity.
