Drug & supplement interaction

Marsh Labrador Tea + Oxaliplatin

Oxaliplatin brand name: Eloxatin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Marsh Labrador Tea and Oxaliplatin 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Marsh Labrador Tea and Oxaliplatin

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 Oxaliplatin and Marsh Labrador Tea 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 Oxaliplatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Oxaliplatin is filed under 4 classifications — including platinum agents, alkylating agents, antineoplastics. Marsh Labrador Tea has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Oxaliplatin’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

No Interaction Found — But Data Suggests Marsh Labrador Tea and Oxaliplatin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

From our pharmacist’s overview on the Oxaliplatin page

“Most of the ten supplements on record for oxaliplatin (Eloxatin), a chemotherapy used against colorectal cancer, are antioxidants such as vitamin C, vitamin E, and coenzyme Q10, and the concern with each is the same, that they might in theory blunt the drug's ability to kill tumor cells.

About Marsh Labrador Tea

What is Marsh Labrador Tea?

Marsh Labrador Tea
  • Colds and respiratory complaints
  • Cough and congestion
  • Mild aches and joint discomfort
  • Topical relief of skin irritation, swelling, and insect bites
  • Traditional use as a diuretic

Marsh Labrador tea is a bog-growing shrub used in folk medicine for coughs, colds, and skin problems, but high-quality human evidence for any use is lacking. Because it contains grayanotoxins (andromedotoxin) that can be poisonous, it is not considered safe for routine use, and pregnant or breastfeeding people should avoid it.

Rhododendron tomentosum · Ericaceae · Leaves and flowering twigs (and an essential oil distilled from them) · Tea (infusion), essential oil, topical preparations

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

Marsh Labrador Tea: dosing

There is no established safe or standardized dose for Marsh Labrador tea. Because the plant naturally contains toxic grayanotoxins, even traditional preparations carry risk, and stronger or longer brews increase that risk.If you choose to use a commercial product, follow the directions on the label exactly and do not exceed them. Never assume that "natural" means harmless.

About Oxaliplatin Injection

What Is Oxaliplatin Injection Used For?

Brand name: Eloxatin

Oxaliplatin Injection is used in combination with two other drugs — fluorouracil and leucovorin — to treat colon and colorectal cancers. It is approved for adjuvant treatment (treatment after surgery to lower the chance of cancer returning) of stage III colon cancer in patients who have had the tumor completely removed.

It is also used to treat advanced colorectal cancer (cancer that has spread or cannot be cured with surgery alone). In both settings, oxaliplatin is always given as part of a combination regimen — it is not used alone.

Oxaliplatin is filed under 4 classifications, and Marsh Labrador Tea has documented interactions with 1 drug class — none of Oxaliplatin's classifications are among them.
