Drug & supplement interaction

Corkwood Tree + Tinidazole

Tinidazole brand name: Tindamax.

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 Corkwood Tree and Tinidazole 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 Tinidazole states a food rule worth keeping to, and 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.

Corkwood Tree and Tinidazole

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 Tinidazole and Corkwood Tree 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 Tinidazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tinidazole is filed under 3 classifications — including cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Corkwood Tree has documented interactions with 1 drug class — the most serious being anticholinergic drugs (moderate) — and none of Tinidazole’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 Corkwood Tree and Tinidazole 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. One of them is worth acting on rather than waiting out — marked below.

  • Confusion Worth acting on Additional detail

    Corkwood Tree

    “Orally, corkwood tree leaves can cause agitation, delirium, and hallucinations. In one case, a 22-year-old male presented with agitation, delirium, and visual hallucinations, among other symptoms, after ingesting 5-10 corkwood tree leaves. Alkaloid constituents in corkwood tree, namely scopolamine and atropine, have anticholinergic effects, which likely explains these adverse psychiatric effects.”

How to take them

Some Tinidazole Products Have a Food Rule — Corkwood Tree Should Not Break It

At least one FDA label for a product containing Tinidazole says to take it with food. If you take Corkwood Tree on an empty stomach out of habit, keep them separate — and take Tinidazole 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 Tinidazole 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.

2 DOSAGE AND ADMINISTRATION 2 DOSAGE AND ADMINISTRATION Trichomoniasis: a single 2 g oral dose taken with food.

From the Dosage and Administration section of the FDA label we read for Tinidazole — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

From our pharmacist’s overview on the Tinidazole page

“Tinidazole (Tindamax) is a short antibiotic course, often for parasitic or vaginal infections, and its supplement list is one I would genuinely slow down for. Each of the three major-rated pairings can wreck treatment in its own way: St.”

About Corkwood Tree

What is Corkwood Tree?

  • Source of scopolamine and hyoscyamine alkaloids
  • Traditional use as a stimulant or for fatigue
  • Historic use for motion sickness (via its alkaloids)
  • Antispasmodic / smooth muscle effects

Corkwood Tree (Duboisia myoporoides) is an Australian plant best known as a commercial source of powerful tropane alkaloids like scopolamine and hyoscyamine, not as a safe home remedy. The raw plant is highly toxic and should not be used as a dietary supplement; only purified, medically prescribed alkaloids derived from it should be used, and only under a doctor's care.

Duboisia myoporoides · Solanaceae · Leaves · Not commonly sold as a consumer supplement; historically a source of plant extracts and isolated alkaloids

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

Corkwood Tree: dosing

There is no safe established dose of Corkwood Tree leaf for self-use, and it should not be taken as a supplement. The only appropriate use of compounds from this plant is in standardized, prescription medicines (such as scopolamine or hyoscyamine) that are dosed and monitored by healthcare professionals.If you have been given a medicine derived from this plant, follow the product label and your prescriber's directions exactly. Do not attempt to make or use any homemade preparation.

About Tinidazole

What Is Tinidazole Used For?

Brand name: Tindamax

Tinidazole tablets treat four types of infections: trichomoniasis (a sexually transmitted infection), giardiasis (a parasitic gut infection), amebiasis (including intestinal infection and amebic liver abscess), and bacterial vaginosis (a vaginal bacterial imbalance). Treatment of giardiasis and amebiasis is approved for adults and children older than three years of age. Bacterial vaginosis is an approved use in adult women.

Because trichomoniasis is sexually transmitted, sexual partners must be treated at the same time to prevent re-infection. Tinidazole should only be used for confirmed or strongly suspected bacterial or parasitic infections — using it unnecessarily can contribute to antibiotic resistance.

Taking Corkwood Tree and Tinidazole Together: Common Questions

Is it safe to take Corkwood Tree with Tinidazole?
We do not list a known interaction between Corkwood Tree and Tinidazole. 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.
Do Corkwood Tree and Tinidazole have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Corkwood Tree and Tinidazole at the same time of day?
At least one FDA label for a product containing Tinidazole says to take it with food. If you take Corkwood Tree on an empty stomach out of habit, keep them separate and take Tinidazole with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Tinidazole products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Corkwood Tree and Tinidazole combination checked?
Interactions in our licensed database are recorded against drug classes. Tinidazole is filed under 3 classifications, and Corkwood Tree has documented interactions with 1 drug class — none of Tinidazole'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 Corkwood Tree interact with any other medications?
Yes. Corkwood Tree has 195 documented drug interactions in our database — Tinidazole 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 Tinidazole interact with any supplements?
Yes. Tinidazole has documented interactions with 140 supplements in our database — Corkwood Tree is not one of them. The Tinidazole interaction page linked on this page lists every one, ranked by severity.
