Cursed Buttercup + Bendamustine
Bendamustine brand names: Treanda, Belrapzo, Vivimusta.
We found no known interaction between Cursed Buttercup 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.
Cursed Buttercup 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 Cursed Buttercup 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 Cursed Buttercup 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.

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 Cursed Buttercup
What is Cursed Buttercup?
- Traditional topical use for skin and joint complaints
- Folk remedy for warts and skin growths (as a counterirritant)
- Historical use for fevers
- Traditional use for swelling or pain
Cursed Buttercup is a toxic wetland plant that can cause severe skin blistering and dangerous poisoning if eaten. It is not a safe or proven dietary supplement, and there is no reliable evidence supporting any medicinal use. Do not take it internally or apply it to your skin without medical supervision—in practice, it is best avoided entirely.
Ranunculus sceleratus · Ranunculaceae · Whole plant (leaves, stems, flowers); historically used topically · Fresh plant poultice or crushed leaves in traditional practice; not sold as a standardized supplement
An interaction check asks whether these two react with each other — it does not ask whether Cursed Buttercup is a good idea for someone in your situation. Here is what our Cursed Buttercup record says about it on its own.
