The bottom line No known interaction

We found no known interaction between Yerba Mate 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.

Interaction report

Yerba Mate 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 Yerba Mate 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. Yerba Mate has documented interactions with 43 drug classes — the most serious being ephedrine (major), adenosine (adenocard) (moderate) and anticoagulant/antiplatelet 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

Yerba Mate in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally. Yerba mate is associated with an increased risk of cancer, including esophageal, kidney, bladder, cervical, prostate, lung, renal cell, and possibly mouth and laryngeal cancer. However, teratogenic studies have not been performed. Yerba mate also contains caffeine. Caffeine crosses the placenta, producing fetal blood concentrations similar to parental levels. According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, most healthy pregnant patients can safely consume caffeine in doses up to 300 mg daily without an increased risk of spontaneous abortion, stillbirth, preterm birth, fetal growth retardation, or congenital malformations. It is generally recommended to avoid consuming more than 300 mg of caffeine daily, or around 6-7 cups of yerba mate daily, when pregnant. High doses of caffeine throughout pregnancy have resulted in symptoms of caffeine withdrawal in newborn infants. Caffeine in doses of greater than 300 mg daily has also been associated with spontaneous abortion, premature delivery, and low birth weight, although one retrospective study found that consuming yerba mate tea during pregnancy was not associated with preterm or small for gestational age births. However, this study did not consider the amount of yerba mate or caffeine consumed, only the frequency of consumption. Some research has found that intrauterine exposure to even modest amounts of caffeine, based on maternal blood levels during the first trimester, is associated with a shorter stature in children ages 4-8 years.

Lactation Possibly Unsafe

When used orally. Yerba mate is associated with an increased risk of cancer, including esophageal, kidney, bladder, cervical, prostate, lung, renal cell, and possibly mouth and laryngeal cancer. Whether carcinogenic constituents of yerba mate are transferred via breast milk is unknown. Yerba mate contains caffeine. Consumption of yerba mate might cause irritability and increased bowel activity in nursing infants.

How to take them

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

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

What is Yerba Mate?

Energy and alertness
Weight loss
Mental focus
Digestive support
Antioxidant support

Yerba mate is a caffeine-containing herbal beverage from South America that is widely enjoyed for its stimulating, coffee-like effects. While it is rich in antioxidants and is being studied for weight, blood sugar, and cholesterol, strong human evidence for most health claims is limited. Drinking very hot mate over many years has been linked to higher risk of certain cancers, so enjoy it warm and in moderation.

Ilex paraguariensis · Aquifoliaceae · Leaves and twigs · Tea (loose leaf or bagged), capsules, tablets, liquid extracts, energy drinks

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

Yerba Mate: dosing

There is no official or standardized medicinal dose for yerba mate. Most people simply drink it as a tea, and the caffeine content varies depending on how it is prepared and how strong it is brewed.If you use a capsule or extract product, follow the directions on the label and do not exceed the recommended amount. Keep your total daily caffeine from all sources in mind.

Taking Yerba Mate and Mineral Oil Together: Common Questions

Is it safe to take Yerba Mate with Mineral Oil?

We do not list a known interaction between Yerba Mate 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 Yerba Mate 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 Yerba Mate 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 Yerba Mate and Mineral Oil combination checked?

Interactions in our licensed database are recorded against drug classes. Mineral Oil is filed under 1 classification, and Yerba Mate has documented interactions with 43 drug classes — 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 Yerba Mate interact with any other medications?

Yes. Yerba Mate has 1,086 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 — Yerba Mate is not one of them. The Mineral Oil interaction page linked on this page lists every one, ranked by severity.
