The bottom line No known interaction

We found no known interaction between Tree Turmeric and Roxithromycin 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.

Tree Turmeric and Roxithromycin

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 Roxithromycin and Tree Turmeric 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 Roxithromycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Roxithromycin is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, oral drugs. Tree Turmeric has documented interactions with 12 drug classes — the most serious being cyclosporine (neoral, sandimmune) (major), tacrolimus (prograf) (major) and anticoagulant/antiplatelet drugs (moderate) — and none of Roxithromycin’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 Tree Turmeric Itself Has Been Linked To

This is not an interaction — nothing below involves Roxithromycin. It is the side-effect record for Tree Turmeric on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Tree Turmeric, this list is the first place to look.

  • Nausea Additional detail

    “Orally, the most common adverse effects of a specific product (Berberol, PharmExtracta) containing tree turmeric and milk thistle extracts include gastrointestinal symptoms, especially nausea.”

See Every Supplement That Interacts With Roxithromycin

This page covers Tree Turmeric only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Roxithromycin page lists 30 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Cannabidiol (cbd) (moderate), Cannabinol (cbn) (moderate) and Cannabis (moderate).

By severity: 1 major · 19 moderate · 10 minor.

From our pharmacist’s overview on the Roxithromycin page

“If you take roxithromycin, an antibiotic prescribed for chest, throat, and skin infections, the entry to sort out first is activated charcoal, the only major-rated interaction among the 30 supplements on file. Charcoal binds medicines in the gut and can pull roxithromycin levels low enough to undercut treatment of the infection itself.”

About Tree Turmeric

What is Tree Turmeric?

  • Blood sugar support
  • High cholesterol
  • Digestive complaints
  • Skin and eye conditions
  • Antimicrobial uses
  • Liver support

Tree turmeric (Berberis aristata) is a shrub used in traditional Indian (Ayurvedic) medicine, valued mainly for its berberine content. Early research suggests possible benefits for blood sugar and cholesterol, but high-quality human evidence is limited. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

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

Tree Turmeric: dosing

There is no well-established standard dose for tree turmeric. They can help you decide whether it is appropriate for you and what amount, if any, is reasonable. Do not assume that a higher dose is safer or more effective.
