Oak Moss + nilotinib
nilotinib brand name: Tasigna.
We found no known interaction between Oak Moss and nilotinib 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.
Oak Moss and nilotinib
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 nilotinib and Oak Moss 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 Oak Moss at all — not against nilotinib, 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.

About Oak Moss
What is Oak Moss?
- Perfume base note and scent fixative
- Aromatherapy and fragrance
- Traditional antimicrobial use
- Soaps and cosmetics fragrance
Oak moss is a lichen that grows on oak and other trees and is best known as a perfume ingredient prized for its earthy, woody scent. There is very little human evidence to support taking it for any health condition, and it is a well-known skin allergen, so it is mainly used externally in fragrances rather than as a dietary supplement.
Evernia prunastri · Parmeliaceae · Whole lichen (thallus) and its extract/absolute · Essential oil, absolute, extract, fragrance ingredient; occasionally tinctures
An interaction check asks whether these two react with each other — it does not ask whether Oak Moss is a good idea for someone in your situation. Here is what our Oak Moss record says about it on its own.
Oak Moss: dosing
There is no established safe or effective oral dose for oak moss. It is not a standard dietary supplement, and reliable dosing information from human studies does not exist.If you come across an oak moss product, follow the directions on the label and do not exceed them. Given the lack of safety data, oral use is generally not recommended.

About Nilotinib
What Is Nilotinib Used For?
Brand name: Tasigna
-
Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells) who have recently found to have this condition in adults and children 1 year of age and older. It is also used to treat certain types of CML in adults whose disease could not be treated successfully with imatinib (Gleevec) or adults who cannot take imatinib because of side effects. Nilotinib is also used to treat certain types of CML in children 1 year of age or older whose disease could not be treated successfully with other tyrosine kinase inhibitor therapies or who cannot take these medications because of side effects. Nilotinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
