Marsh Labrador Tea and Aluminum Hydroxide

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 Aluminum Hydroxide 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 Aluminum Hydroxide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aluminum Hydroxide is filed under 3 classifications — including antacids, oral drugs. Marsh Labrador Tea has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Aluminum Hydroxide’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 Marsh Labrador Tea Itself Has Been Linked To

This is not an interaction — nothing below involves Aluminum Hydroxide. It is the side-effect record for Marsh Labrador Tea on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Marsh Labrador Tea, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on Additional detail

    “Orally, large amounts of marsh Labrador tea can cause poisoning due to its ledol constituent (2). The essential oil of marsh Labrador tea can cause severe irritation of the gastrointestinal tract, vomiting, diarrhea, irritation and damage to the kidneys and urinary tract, heavy perspiration, myalgias, and arthralgias.”

We haven’t matched Aluminum Hydroxide to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Aluminum Hydroxide.

From our pharmacist’s overview on the Aluminum Hydroxide page

“An antacid sounds harmless, and that is exactly why the supplement interactions with aluminum hydroxide (Amphojel, Gaviscon) deserve real attention before you combine it with much of anything. The most serious entry is activated charcoal, which can soak up many medications in the gut and sharply cut how much of them your body actually…”

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.
