Spotted Geranium + Entrectinib
Entrectinib brand name: Rozlytrek.
We found no known interaction between Spotted Geranium 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.
Spotted Geranium 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 Spotted Geranium 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 Spotted Geranium 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 does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Spotted Geranium 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 Spotted Geranium reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Spotted Geranium 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 Spotted Geranium
What is Spotted Geranium?
- Diarrhea
- Mouth and throat sores
- Bleeding and wound care
- Hemorrhoids
- Sore throat gargle
Spotted Geranium (Geranium maculatum), also called wild geranium or cranesbill, is a North American woodland plant whose tannin-rich root has long been used in folk medicine as an astringent for diarrhea, minor bleeding, and mouth or throat irritation. Modern human studies are very limited, so its effectiveness is largely unproven. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.
Geranium maculatum · Geraniaceae · Root and rhizome (sometimes the dried leaves) · Dried root, tea, tincture, powder, capsules

There is no established standard dose for Spotted Geranium. Traditional use involved teas, tinctures, and gargles made from the dried root, but amounts varied widely and were not standardized.If you choose to use a commercial 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.
