Mountain Laurel + Mineral Oil
Mineral Oil brand name: Kondremul Plain.
We found no known interaction between Mountain Laurel 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.
Mountain Laurel 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 Mountain Laurel 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 Mountain Laurel at all — not against Mineral Oil, 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.

Some Mineral Oil Products Have a Food Rule — Mountain Laurel Should Not Break It
At least one FDA label for a product containing Mineral Oil says to take it with food. If you take Mountain Laurel 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.
See Every Supplement That Interacts With Mineral Oil
This page covers Mountain Laurel 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 Mountain Laurel
What is Mountain Laurel?
- Skin conditions (folk use)
- Pain and inflammation (folk use)
- Diarrhea (historical folk use)
- Fever (historical folk use)
Mountain Laurel is a flowering shrub native to North America that contains toxic compounds called grayanotoxins, making it dangerous to eat or use internally. There is no reliable evidence that it is safe or effective as a supplement, and poisoning can be serious. We strongly recommend avoiding it.
Kalmia latifolia · Ericaceae · Leaves (historically); rarely used today · Not commonly available as a supplement; historically used as crude leaf preparations or tinctures
An interaction check asks whether these two react with each other — it does not ask whether Mountain Laurel is a good idea for someone in your situation. Here is what our Mountain Laurel record says about it on its own.
Mountain Laurel: dosing
There is no established or safe dose of Mountain Laurel for any use. It is not recommended as a dietary supplement, and no standardized preparations are considered safe to take internally.Because of its toxicity, the safest approach is to avoid using it altogether.
