Wormseed + Mesalamine

Mesalamine brand names: Pentasa, Asacol, Canasa, Rowasa, Lialda, and others.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Wormseed and Mesalamine 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 label for Mesalamine states a food rule worth keeping to.

Wormseed and Mesalamine

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 Mesalamine and Wormseed 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 Wormseed at all — not against Mesalamine, 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.

What to actually watch for

What Wormseed Itself Has Been Linked To

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

  • Muscle pain Additional detail

    “Orally, wormseed is unsafe.

    Serious Adverse Effects (Rare):

    Symptoms of poisoning are possible in the amounts traditionally used as medicine. Symptoms of toxicity include epileptiform spasms, gastroenteritis, kidney irritation, muscle twitching, stupor, visual disorders, and even death.”

    Wormseed · Natural Medicines adverse-effect record, reported in poisoning.

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

How to take them

Some Mesalamine Products Have a Food Rule — Wormseed Should Not Break It

At least one FDA label for a product containing Mesalamine says to take it with food. If you take Wormseed on an empty stomach out of habit, keep them separate — and take Mesalamine with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Mesalamine products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2 ) Administer mesalamine delayed-release tablets with food.

From the Dosage and Administration section of the FDA label we read for Mesalamine — where that label names a specific product, the instruction is that product's. See the Mesalamine drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Everything else you take

See Every Supplement That Interacts With Mesalamine

This page covers Wormseed only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mesalamine page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Mesalamine page

“Activated charcoal is the one entry here I would treat as a genuine problem for anyone taking mesalamine (Asacol, Lialda, Pentasa, and others). It is the lone major-rated interaction among the 17 on file, because charcoal soaks up drugs in the gut and can pull mesalamine out of the picture before it does its job.”

About Wormseed

What is Wormseed?

  • Intestinal worms and parasites
  • Digestive upset and gas
  • Cooking herb (culinary use as epazote)
  • Menstrual complaints
  • Respiratory symptoms

Wormseed (also called epazote) is a strong-smelling herb traditionally used to expel intestinal worms and to flavor food. Its essential oil is potentially toxic and has caused serious poisoning, so it should never be used in medicinal amounts without professional guidance. Modern deworming medicines are far safer and more reliable.

Dysphania ambrosioides · Amaranthaceae · Leaves, seeds, flowering tops, and essential oil (oil of chenopodium) · Tea, dried herb, tincture, and essential oil

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

Wormseed: dosing

There is no well-established or standardized medicinal dose for wormseed, and the essential oil has a narrow margin between a useful amount and a toxic one. As a food seasoning (epazote), the small amounts used in cooking are considered safe for most people.

About Mesalamine

What Is Mesalamine Used For?

Brand names: Pentasa, Asacol, Canasa, Rowasa, Lialda, Delzicol

Mesalamine is used to treat mildly to moderately active ulcerative colitis — a condition where the lining of the large intestine becomes inflamed and ulcerated. Depending on the product and formulation, it can be used to bring the disease under control (induction of remission) and/or to keep it from coming back (maintenance of remission).

Different products target different parts of the lower digestive tract. Oral forms (tablets and capsules) treat the colon more broadly. Rectal forms — including enemas (ROWASA, sfROWASA, mesalamine rectal suspension) — are used for distal ulcerative colitis, proctosigmoiditis, or proctitis (inflammation limited to the lower end of the colon or rectum). Rectal suppositories (CANASA, mesalamine rectal suppositories) are specifically for ulcerative proctitis (inflammation of the rectum only).

Taking Wormseed and Mesalamine Together: Common Questions

Is it safe to take Wormseed with Mesalamine?
We do not list a known interaction between Wormseed and Mesalamine. 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.
Should I take Wormseed and Mesalamine at the same time of day?
At least one FDA label for a product containing Mesalamine says to take it with food. If you take Wormseed on an empty stomach out of habit, keep them separate and take Mesalamine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Mesalamine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Mesalamine interact with any supplements?
Yes. Mesalamine has documented interactions with 17 supplements in our database — Wormseed is not one of them. The Mesalamine interaction page linked on this page lists every one, ranked by severity.
