Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Chaparral 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.

Chaparral 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 Chaparral 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. Chaparral has documented interactions with 1 drug class — the most serious being hepatotoxic drugs (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.

Keep it in perspective

What Chaparral Itself Has Been Linked To

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

  • Yellowing of the skin or eyes / Liver problems Worth acting on Additional detail

    “Chaparral is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Orally, chaparral can cause hepatoxicity, resulting in jaundice, fatigue, right upper quadrant abdominal pain, dark urine, light stools, nausea, diarrhea, weight loss, fever, and anorexia.”

How to take them

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

At least one FDA label for a product containing Mineral Oil says to take it with food. If you take Chaparral 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 Chaparral 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 Chaparral

What is Chaparral?

Chaparral
  • Pain and inflammation
  • Skin conditions
  • Antioxidant/general wellness
  • Infections
  • Traditional 'detox' remedies

Chaparral is a desert shrub long used in traditional medicine, but there is no reliable proof it treats any condition. It has been linked to serious and sometimes irreversible liver and kidney damage, and the FDA has warned against using it. Because of these safety concerns, we recommend avoiding chaparral.

Larrea tridentata · Zygophyllaceae · Leaves and twigs · Tea, capsules, tablets, tinctures, topical salves

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

Chaparral: dosing

There is no safe or established dose for chaparral. For chaparral specifically, the best advice is to avoid it.

Taking Chaparral and Mineral Oil Together: Common Questions

Is it safe to take Chaparral with Mineral Oil?
We do not list a known interaction between Chaparral and Mineral Oil. 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 Chaparral and Mineral Oil at the same time of day?
At least one FDA label for a product containing Mineral Oil says to take it with food. If you take Chaparral on an empty stomach out of habit, keep them separate and take Mineral Oil with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Mineral Oil products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Chaparral and Mineral Oil combination checked?
Interactions in our licensed database are recorded against drug classes. Mineral Oil is filed under 1 classification, and Chaparral 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.
Does Chaparral interact with any other medications?
Yes. Chaparral has 370 documented drug interactions in our database — Mineral Oil 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 Mineral Oil interact with any supplements?
Yes. Mineral Oil has documented interactions with 17 supplements in our database — Chaparral is not one of them. The Mineral Oil interaction page linked on this page lists every one, ranked by severity.
