Carlina + Entrectinib
Entrectinib brand name: Rozlytrek.
We found no known interaction between Carlina and Entrectinib 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.
Carlina and Entrectinib
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 Entrectinib and Carlina 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Carlina at all — not against Entrectinib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.

Where Carlina and Entrectinib Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.

#1,026 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.
Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Carlina is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Carlina reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Carlina and Entrectinib records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Carlina
What is Carlina?
- Digestive upset and poor appetite
- Diuretic (increasing urine flow)
- Skin conditions when used topically
- Antimicrobial folk remedy
- Mild laxative or 'detox' use
Carlina (Carlina acaulis) is a thistle-like plant whose root has long been used in European folk medicine for digestive and skin complaints. Modern scientific evidence in humans is very limited, so its benefits are largely unproven. Because safety data are sparse, talk with a 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 Carlina is a good idea for someone in your situation. Here is what our Carlina record says about it on its own.
Carlina: dosing
There is no well-established or standardized dose for Carlina. Traditional preparations were often made as a root tea or tincture, but the right amount, strength, and safe length of use have not been defined by good research.If you choose to use a product, follow the directions on the label and do not exceed them.

About Entrectinib
What Is Entrectinib Used For?
Brand name: Rozlytrek
Rozlytrek (entrectinib) is used to treat adult patients with ROS1-positive metastatic non-small cell lung cancer (NSCLC), as confirmed by an FDA-approved test. It is also approved for adult and pediatric patients older than 1 month of age who have solid tumors — any cancer type — that carry an NTRK gene fusion detected by an FDA-approved test, provided the tumor has no known acquired resistance mutation, is metastatic or cannot be surgically removed without severe harm, and has progressed after prior treatment or has no satisfactory alternative therapy.
The NTRK gene fusion approval in solid tumors was granted under accelerated approval, meaning it is based on tumor response rates. Continued approval may depend on results from confirmatory clinical trials.
