Javanese Turmeric + Elbasvir, Grazoprevir

Elbasvir, Grazoprevir brand name: Zepatier.

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 Javanese Turmeric and Elbasvir, Grazoprevir 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 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.

Interaction report

Javanese Turmeric and Elbasvir, Grazoprevir

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 Elbasvir, Grazoprevir and Javanese 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.

Javanese Turmeric safety at a glance

Javanese Turmeric overall Use caution Generally well tolerated in food-like amounts, but human safety data for concentrated supplements are limited.
Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Elbasvir, Grazoprevir

Interactions in our licensed database are recorded against drug classes, not just single drug names. Elbasvir, Grazoprevir is filed under 4 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, cytochrome p450 3a4 (cyp3a4) substrates. Javanese Turmeric has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Elbasvir, Grazoprevir’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 Javanese Turmeric and Elbasvir, Grazoprevir May Share a Side Effect

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.

About Javanese Turmeric

What is Javanese Turmeric?

  • Digestive upset and bloating
  • Liver and gallbladder support
  • Loss of appetite
  • Joint and inflammation complaints
  • General wellness tonic

Javanese turmeric (Curcuma zanthorrhiza), known in Indonesia as temulawak, is a ginger-family root traditionally used for digestive and liver complaints. Early lab and animal studies are interesting, but strong human evidence is limited, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to a pharmacist or doctor before using it, especially if you have a health condition or take medications.

Curcuma zanthorrhiza · Zingiberaceae · Rhizome (root) · Capsules, tablets, powder, dried root, tea, liquid extracts

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

Javanese Turmeric: dosing

There is no well-established standardized dose for Javanese turmeric.
