Thuja and Aluminum Hydroxide, Aspirin, Magnesium 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, Aspirin, Magnesium Hydroxide and Thuja 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, Aspirin, Magnesium Hydroxide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Aluminum Hydroxide, Aspirin, Magnesium Hydroxide is filed under 9 classifications — including antacids, aspirin, nonsteroidal anti-inflammatory drugs (nsaids). Thuja has documented interactions with 3 drug classes — the most serious being anticonvulsants (moderate), immunosuppressants (moderate) and seizure threshold lowering drugs (moderate) — and none of Aluminum Hydroxide, Aspirin, Magnesium 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 Thuja Itself Has Been Linked To

This is not an interaction — nothing below involves Aluminum Hydroxide, Aspirin, Magnesium Hydroxide. It is the side-effect record for Thuja on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Thuja, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on Additional detail

    “Orally, large doses of thuja have been reported to cause toxicity involving headache, nervous agitation, seizures, gastric irritation, vomiting, abdominal pain, and diarrhea. Thuja toxicity has also been reported to cause liver damage, renal toxicity, and death in some cases.”

What Aluminum Hydroxide, Aspirin, Magnesium Hydroxide Is Prescribed For, and What Thuja Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Aluminum Hydroxide, Aspirin, Magnesium Hydroxide is a prescription medicine with approved uses on its FDA label. Thuja is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Aluminum Hydroxide, Aspirin, Magnesium Hydroxide is prescribed for: Aspirin is used to temporarily relieve minor aches and pains from headaches, backaches, muscle aches, toothaches, menstrual cramps, the common cold, and minor arthritis pain. It also temporarily reduces fever. Some coated aspirin tablet products note that, under a doctor's supervision, aspirin can help prevent another heart attack or stroke in adults who have already had one. Because of their delayed-release design, those coated products will not give fast relief for headaches or other symptoms needing quick relief.

Thuja has been studied for:

  • Common cold studied, not established Thuja has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Thuja for common cold

    Clinical research in patients with moderate cold symptoms shows that taking three tablets of a specific combination product (Esberitox, Schaper & Brümmer GmbH & Co. KG) containing dry extracts of echinacea root, thuja leaf, and wild indigo root three times daily for 7-9 days improves the severity of cold symptoms, general well-being, and overall response rate when compared with placebo.

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 Aluminum Hydroxide, Aspirin, Magnesium Hydroxide on your own; if you are taking Thuja for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Aluminum Hydroxide, Aspirin, Magnesium Hydroxide page

“Ascriptin combines aspirin with two antacids, aluminum hydroxide and magnesium hydroxide, and the aspirin part already thins the blood on its own. That is why more than 200 of the 255 ingredients listed here can raise bleeding risk, and why this page deserves a careful read rather than a quick skim.”

About Thuja

What is Thuja?

  • Warts and skin growths
  • Respiratory and immune support
  • Cold and upper respiratory symptoms
  • Topical skin conditions
  • Traditional use as a diuretic or to bring on menstruation

Thuja, also called northern white cedar or arborvitae, is a tree whose leaf and oil have a long history in folk and homeopathic medicine, especially for warts and immune support. Solid human evidence for these uses is very limited, and the undiluted oil contains thujone, which can be toxic. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Thuja occidentalis · Cupressaceae · Leaves (young twigs/branch tips) and essential oil · Homeopathic pellets, tinctures, topical ointments, essential oil, capsules, and combination cold/immune products

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

Thuja: dosing

There is no well-established standard dose for thuja, and products vary widely in strength. Homeopathic pellets, tinctures, and topical creams all use different concentrations.Because the essential oil contains potentially toxic thujone, it should not be taken by mouth without professional guidance.

Taking Thuja and Aluminum Hydroxide, Aspirin, Magnesium Hydroxide Together: Common Questions

Is it safe to take Thuja with Aluminum Hydroxide, Aspirin, Magnesium Hydroxide?

Aluminum Hydroxide, Aspirin, Magnesium Hydroxide is filed under 9 classifications, and Thuja has documented interactions with 3 drug classes — none of Aluminum Hydroxide, Aspirin, Magnesium Hydroxide'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.
