Larch Turpentine and Mitomycin

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 Mitomycin and Larch Turpentine 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 Larch Turpentine at all — not against Mitomycin, 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 the ADVERSE REACTIONS section of the FDA label for Mitomycin.

See Every Supplement That Interacts With Mitomycin

This page covers Larch Turpentine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mitomycin page lists 26 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Acerola (moderate), Alpha-lipoic Acid (moderate), Coffee Charcoal (moderate) and Dimethylsulfoxide (dmso) (moderate).

By severity: 1 major · 15 moderate · 10 minor.

From our pharmacist’s overview on the Mitomycin page

“Activated charcoal is the entry to know first with mitomycin (Mutamycin, Mitosol, Jelmyto), a chemotherapy drug, because charcoal binds medications and can cut the amount the body receives, and it carries this list's only major rating. A weakened dose of a cancer treatment is a real loss, so I would treat these 26 interactions with gen…”

About Larch Turpentine

What is Larch Turpentine?

  • Muscle and joint aches
  • Chest congestion and coughs
  • Minor skin inflammation
  • Boils and abscesses (drawing salves)
  • Counterirritant for pain relief

Larch turpentine is a sticky resin from European larch trees that has long been used in ointments and chest rubs for sore muscles and congestion. Solid scientific evidence for these uses is very limited, and it can irritate skin and airways, so it should be used only externally, with care, and never swallowed.

Larix decidua · Pinaceae · Resin (oleoresin) collected from the trunk; sometimes distilled into turpentine oil · Ointments, plasters, balms, and inhalation/vapor preparations; essential oil

An interaction check asks whether these two react with each other — it does not ask whether Larch Turpentine is a good idea for someone in your situation. Here is what our Larch Turpentine record says about it on its own.

Larch Turpentine: dosing

There is no well-established standardized dose for larch turpentine. It is usually found mixed into ointments, plasters, or rubs at low concentrations.The safest approach is to follow the directions on the specific product label and use only the amount recommended.

About Mitomycin

What Is Mitomycin Used For?

Brand names: Mutamycin, Mitosol, Jelmyto

Mitomycin (and its brand Mutamycin) is used intravenously in combination with other chemotherapy drugs to treat disseminated adenocarcinoma (a type of cancer that has spread) of the stomach or pancreas, when other treatments have not worked. It is not intended to replace surgery or radiation therapy.

Mitomycin is also the active ingredient in other products for different uses: Jelmyto treats low-grade upper tract urothelial cancer (cancer of the upper urinary tract); Zusduri treats recurrent low-grade intermediate-risk non-muscle invasive bladder cancer; and Mitosol is used as a surgical aid during certain glaucoma eye surgery. These are separate products with distinct indications and are not interchangeable with the intravenous injection form.
