Pedunculate Oak + Infigratinib
Infigratinib brand name: Truseltiq.
We found no known interaction between Pedunculate Oak and Infigratinib 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.
Pedunculate Oak and Infigratinib
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 Infigratinib and Pedunculate Oak 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 Pedunculate Oak at all — not against Infigratinib, 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.

From our pharmacist’s overview on the Infigratinib page
“Infigratinib (Truseltiq) treats a form of bile duct cancer, and the supplements on this list deserve genuine care, because most of them can shift how much of the drug actually reaches your blood. Nearly all of these interactions run through CYP3A4, the liver enzyme that breaks infigratinib down.”

About Pedunculate Oak
What is Pedunculate Oak?
- Diarrhea
- Sore throat and mouth inflammation
- Skin irritation and minor wounds
- Hemorrhoids
- Excessive sweating
Pedunculate oak bark is a traditional astringent remedy used mainly for mild diarrhea, sore throat, and skin or anal irritation, thanks to its high tannin content. Evidence comes mostly from tradition and laboratory studies rather than strong human trials, so use it short-term and check with a pharmacist or doctor before trying it.
Quercus robur · Fagaceae · Bark, and sometimes the galls and acorns · Dried bark for tea or decoction, liquid extracts, and bark powder for compresses, baths, or gargles
An interaction check asks whether these two react with each other — it does not ask whether Pedunculate Oak is a good idea for someone in your situation. Here is what our Pedunculate Oak record says about it on its own.
Pedunculate Oak: dosing
There is no single standardized dose of pedunculate oak bark that applies to everyone, and amounts vary by product and how it is used (tea, gargle, wash, or bath).The best approach is to follow the directions on the product label and not exceed them. Traditional use generally limits internal use to a few days only.

About Infigratinib
What Is Infigratinib Used For?
Brand name: Truseltiq
-
Infigratinib is used in adults who have received previous therapy to treat a certain type of cholangiocarcinoma (bile duct cancer) that has spread to nearby tissues or other parts of the body and cannot be removed by surgery. Infigratinib 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 stop or slow the spread of cancer cells.
