The bottom line No known interaction

We found no known interaction between Groundsel and Mineral Oil 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 Mineral Oil states a food rule worth keeping to.

Groundsel and Mineral Oil

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 Mineral Oil and Groundsel 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.

How we checked

Why No Interaction Is Listed for Mineral Oil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mineral Oil is filed under a single classification — oral drugs. Groundsel has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) inducers (moderate) — and none of Mineral Oil’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

What Groundsel Itself Has Been Linked To

This is not an interaction — nothing below involves Mineral Oil. It is the side-effect record for Groundsel on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Groundsel, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on Additional detail

    “Groundsel contains pyrrolizidine alkaloids (PA), which might cause pneumotoxicity. Animal research shows that PA-associated pneumotoxicity occurs as pulmonary hypertension and right ventricular hypertrophy.”

  • Liver problems Worth acting on Additional detail

    “Orally, groundsel may cause hepatotoxicity due to its pyrrolizidine alkaloid (PA) constituents. Chronic exposure hepatotoxic PAs is associated with veno-occlusive disease. Subacute veno-occlusive disease causes vague symptoms with persistent liver enlargement. Symptoms of acute veno-occlusive disease include colicky pains in epigastrium, vomiting and diarrhea, and ascites formation within several days.”

Special populations

Groundsel in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally. Groundsel products can contain pyrrolizidine alkaloid (PA) constituents, which might be teratogenic and hepatotoxic. There is insufficient reliable information available about the safety of using groundsel products that do not contain hepatotoxic PAs during pregnancy. However, dietary supplements sold in the US are not required to include the amount of PAs they contain; therefore, all preparations used orally containing groundsel should be considered likely unsafe.

Lactation Likely Unsafe

When used orally. Hepatotoxic PA constituents in groundsel are excreted in milk. There is insufficient reliable information available about the safety of using groundsel products that do not contain hepatotoxic PAs during lactation. However, dietary supplements sold in the US are not required to include the amount of PAs they contain; therefore, all preparations used orally containing groundsel should be considered likely unsafe.

How to take them

Some Mineral Oil Products Have a Food Rule — Groundsel Should Not Break It

At least one FDA label for a product containing Mineral Oil says to take it with food. If you take Groundsel on an empty stomach out of habit, keep them separate — and take Mineral Oil 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 Mineral Oil 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.

Directions: * Do not take with meals.

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

This page covers Groundsel only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mineral Oil 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 Mineral Oil page

“Everything on record for mineral oil (Kondremul Plain) comes down to one theme, absorption in the gut, and it deserves genuine care, chiefly because of activated charcoal. Charcoal binds a wide array of medicines and can sharply cut how much of them the body actually takes in, and it carries this list's only major rating, so understand…”

About Groundsel

What is Groundsel?

  • Menstrual complaints
  • Digestive upset
  • Minor wounds (topical)
  • Sore gums or mouth
  • Mild aches

Groundsel is a common weed traditionally used as a folk remedy, but it contains pyrrolizidine alkaloids that can cause serious liver damage. There is no reliable evidence that it works for any condition, and most health authorities consider it unsafe to take internally. We do not recommend using it.

Senecio vulgaris · Asteraceae · Aerial parts (leaves, stems, flowers) · Tea, dried herb, tincture, topical poultice

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

Groundsel: dosing

There is no established safe dose for groundsel. Because of its toxic pyrrolizidine alkaloids, no standardized, tested dosing exists, and we do not recommend taking it internally.If you come across a product that contains groundsel, do not assume any amount is safe.

About Mineral Oil

What Is Mineral Oil Used For?

Brand name: Kondremul Plain

Most mineral oil products are used to relieve occasional constipation. Rectal enema products — including Fleet, Leader Ready to Use Mineral Oil, Foster and Thrive Ready to Use Mineral oil, Enema, and Enema Mineral Oil — are also used for relief of fecal impaction (stool that is stuck and won't pass) and to remove residue left in the bowel after a barium procedure.

Humco Mineral Oil Light topical liquid is used to help treat and prevent diaper rash, protect chafed skin, and seal out wetness. HANHOO BlemishPatch is applied directly to skin concerns as a topical patch.

Taking Groundsel and Mineral Oil Together: Common Questions

Interactions in our licensed database are recorded against drug classes. Mineral Oil is filed under 1 classification, and Groundsel has documented interactions with 1 drug class — none of Mineral Oil'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.
