The bottom line No known interaction

We found no known interaction between Nasturtium and Bendamustine 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.

Nasturtium and Bendamustine

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 Bendamustine and Nasturtium 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 Nasturtium at all — not against Bendamustine, 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.

Nasturtium safety at a glance

Nasturtium overall Use caution Generally considered safe as a food, but concentrated extracts have limited safety data.
Pregnancy Avoid Not enough safety information; medicinal amounts are best avoided during pregnancy.
Breastfeeding Use caution Safety during breastfeeding is not well studied, so caution is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Nasturtium Itself Has Been Linked To

This is not an interaction — nothing below involves Bendamustine. It is the side-effect record for Nasturtium on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Nasturtium, this list is the first place to look.

  • A skin rash Additional detail

    “Orally, large amounts of nasturtium or benzyl mustard oil, a constituent of nasturtium, can cause gastrointestinal tract irritation (2,18). Large amounts of nasturtium can cause albuminuria due to glomerular and tubular damage (2).

    Topically, contact with the nasturtium plant and its benzyl mustard oil constituent can cause skin and mucosal irritation (2,18).”

    “Topically, contact with the nasturtium plant and its benzyl mustard oil constituent can cause skin and mucosal irritation (2,18). Benzyl mustard oil is a contact allergen if applied to the skin. There are multiple case reports of contact dermatitis attributed to nasturtium.”

Everything above comes from the Natural Medicines adverse-effect record for Nasturtium — expand a row for the licensed statement it rests on. We haven’t matched Bendamustine to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Bendamustine.

From our pharmacist’s overview on the Bendamustine page

“Bendamustine (Treanda, Belrapzo, Vivimusta) is IV chemotherapy for chronic lymphocytic leukemia and certain lymphomas, and the liver clears it through an enzyme called CYP1A2. That enzyme is why nearly all 87 supplements on this page appear here, since about 80 of them can push CYP1A2 up or down, which could either raise side effects o…”

About Nasturtium

What is Nasturtium?

  • Urinary tract infections
  • Respiratory infections and congestion
  • Antimicrobial support
  • Wound and skin care (topical)
  • Mild cold and cough symptoms

Nasturtium is an edible garden plant traditionally used for urinary and respiratory infections, often combined with horseradish in herbal products. Some lab studies suggest it has antimicrobial activity, but high-quality human evidence is limited. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have kidney or stomach problems.

Tropaeolum majus · Tropaeolaceae · Leaves, flowers, and seeds · Fresh leaves and flowers (food/salad), dried herb, tea, capsules, tinctures, and combination herbal products

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

Nasturtium: dosing

There is no well-established standardized dose for nasturtium. Amounts vary widely depending on whether you use fresh leaves, dried herb, tea, capsules, or a combination product.The best approach is to follow the directions on the product label and not exceed the recommended amount.

For CLL, how well bendamustine works compared to other first-line treatments (aside from chlorambucil) has not been fully established.
