White Sandalwood + Larotrectinib
Larotrectinib brand name: Vitrakvi.
We found no known interaction between White Sandalwood and Larotrectinib 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.
White Sandalwood and Larotrectinib
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 Larotrectinib and White Sandalwood 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.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Larotrectinib
Interactions in our licensed database are recorded against drug classes, not just single drug names. Larotrectinib is filed under 3 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. White Sandalwood has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Larotrectinib’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.

From our pharmacist’s overview on the Larotrectinib page
“Nearly everything on this page interacts with larotrectinib (Vitrakvi) in one of two directions, raising or lowering how much of the drug ends up in your blood. Larotrectinib treats cancers driven by an NTRK gene fusion, and it is cleared by a liver enzyme called CYP3A4, so herbs that speed that enzyme up can drain the drug's effect wh…”

About White Sandalwood
What is White Sandalwood?
- Relaxation and stress relief
- Skin soothing and cosmetics
- Aromatherapy and meditation
- Traditional remedy for urinary discomfort
- Fragrance and perfumes
White sandalwood is a fragrant wood from the Santalum album tree, used for centuries in perfumes, incense, skincare, and traditional medicine. Most of its popular uses—like relaxation and skin care—are based on tradition and lab studies rather than strong human research. Use it cautiously, especially on the skin or by mouth, and talk to your pharmacist or doctor before using it as a remedy.
Santalum album · Santalaceae · Heartwood and essential oil · Essential oil, powder, paste, incense, skincare products, and occasionally capsules or tablets
An interaction check asks whether these two react with each other — it does not ask whether White Sandalwood is a good idea for someone in your situation. Here is what our White Sandalwood record says about it on its own.
White Sandalwood: dosing
There is no established standardized dose for white sandalwood, and reliable human dosing information for oral use is lacking. Never swallow undiluted essential oil, and dilute oils properly before applying them to your skin. When in doubt, choose products from reputable manufacturers and use the smallest amount needed.
From our White Sandalwood monograph — the full record covers uses, side effects and every documented interaction.
About Larotrectinib
What Is Larotrectinib Used For?
Brand name: Vitrakvi
Vitrakvi is used to treat adult and pediatric patients with solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion — a specific genetic alteration that can drive tumor growth. It is used when the tumor is metastatic (has spread) or when surgery to remove it would likely cause serious harm, and when there are no satisfactory alternative treatments or the cancer has continued to grow after prior treatment.
Patients must be selected for Vitrakvi therapy based on an FDA-approved test that confirms the NTRK gene fusion in their tumor. This approval is under the FDA's accelerated approval pathway, based on how many patients responded to treatment and how long those responses lasted. Continued approval may depend on results from follow-up clinical trials.
