Interaction report

Marsh Labrador Tea and Sodium Bicarbonate (OTC Drug)

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 Sodium Bicarbonate (OTC Drug) 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 Sodium Bicarbonate (OTC Drug)

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sodium Bicarbonate (OTC Drug) is filed under 2 classifications — antacids, oral drugs. Marsh Labrador Tea has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Sodium Bicarbonate (OTC Drug)’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 Sodium Bicarbonate (OTC Drug). 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.”

Everything above comes from the Natural Medicines adverse-effect record for Marsh Labrador Tea — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Sodium Bicarbonate (OTC Drug)’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Sodium Bicarbonate (OTC Drug) column appears here.

What Sodium Bicarbonate (OTC Drug) Is Prescribed For, and What Marsh Labrador Tea Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Sodium Bicarbonate (OTC Drug) is a prescription medicine with approved uses on its FDA label. Marsh Labrador Tea is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Sodium Bicarbonate (OTC Drug) is prescribed for: Sodium bicarbonate treats several different types of discomfort depending on the product and how it is used. Taken by mouth, it relieves heartburn, sour stomach, acid indigestion, and upset stomach. EcoDent Ultimate Essential Mouthcare oral solution is used to temporarily clean minor mouth wounds and soothe minor gum inflammation from dental procedures, dentures, orthodontic appliances, or accidental injury. Used on the skin, sodium bicarbonate products — including After Bite Kids cream, After Bite Advanced and After Bite X Tech liquids, Itch Eraser Sensitive cream, AHHH Bite Relief gel, Insect sting relief latex lotion, Insect sting relief pad, and Dermfree Insect Bite Relief liquid — temporarily relieve minor skin irritation and itching from insect bites, stings, and contact with poison ivy, oak, or sumac.

AHHH Bite Relief also provides rapid relief from specific biting insects including deer flies, horse flies, black flies, mosquitoes, bees, wasps, and chiggers, and from rashes and eczema.

Marsh Labrador Tea has been studied for:

  • Insect bite studied, not established Marsh Labrador Tea has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Marsh Labrador Tea for insect bite

    Topical marsh Labrador tea has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Sodium Bicarbonate (OTC Drug) on your own; if you are taking Marsh Labrador Tea for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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.
