Drug & supplement interaction

Asian Water Plantain + Carmustine

Carmustine brand names: Gliadel, BiCNU, Gliadel Wafer.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Asian Water Plantain and Carmustine 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.

Asian Water Plantain and Carmustine

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 Carmustine and Asian Water Plantain 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.

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.

How we checked

Why No Interaction Is Listed for Carmustine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Carmustine is filed under 2 classifications — alkylating agents, oral drugs. Asian Water Plantain has documented interactions with 1 drug class — the most serious being nephrotoxic drugs (minor) — and none of Carmustine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Asian Water Plantain and Carmustine May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Bleeding or bruising Worth acting on Additional detail

    Asian Water Plantain

    “One case report of drug-induced systemic toxicity, including hepatotoxicity, has occurred in a 59-year-old man with chronic hepatitis B who had taken six doses of a combination product containing Asian water plantain 3 weeks prior to admission. He presented with gum bleed and petechiae, and his admission lab values indicated fulminant liver failure.”

Everything else you take

See Every Supplement That Interacts With Carmustine

This page covers Asian Water Plantain only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Carmustine page lists 24 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), Coenzyme Q10 (moderate) and Coffee Charcoal (moderate).

By severity: 1 major · 14 moderate · 9 minor.

From our pharmacist’s overview on the Carmustine page

“Activated charcoal is the entry to understand first. It holds the only major rating among the 24 ingredients on file for carmustine, and because it can trap drugs that recirculate through the gut, it may lower carmustine levels even when the chemotherapy arrives by IV or as an implanted Gliadel wafer.”

About Asian Water Plantain

What is Asian Water Plantain?

Asian Water Plantain
  • Promoting urination (diuretic)
  • Fluid retention and swelling
  • Urinary discomfort
  • Cholesterol and heart health support
  • Kidney and bladder support

Asian water plantain (Ze Xie) is a rhizome long used in traditional Chinese medicine, mainly as a diuretic and for fluid retention. Modern evidence is mostly limited to laboratory and animal studies, so its benefits in people are not well proven, and quality human safety data are lacking. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Alisma plantago-aquatica · Alismataceae · Dried rhizome (root-like stem), known as Rhizoma Alismatis or Ze Xie · Dried sliced rhizome, powders, decoctions (teas), capsules, and as part of multi-herb traditional Chinese medicine formulas

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

Asian Water Plantain: dosing

There is no well-established standardized dose for Asian water plantain as a supplement. In traditional Chinese medicine, the dried rhizome is typically used as part of a multi-herb formula prepared by a trained practitioner, not taken alone.If you use a commercial product, follow the directions on the label and do not exceed the recommended amount. Do not use it as a substitute for prescribed diuretics or other proven treatments.

Carmustine is filed under 2 classifications, and Asian Water Plantain has documented interactions with 1 drug class — none of Carmustine's classifications are among them.
