Drug & supplement interaction

Bayberry + Cisplatin

Cisplatin brand name: Platinol-AQ.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Bayberry and Cisplatin 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.

Interaction report

Bayberry and Cisplatin

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 Cisplatin and Bayberry 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 Bayberry at all — not against Cisplatin, 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.

What to actually watch for

No Interaction Found — But Data Suggests Bayberry and Cisplatin May Share Several of the Same Side Effects

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.

See Every Supplement That Interacts With Cisplatin

This page covers Bayberry only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cisplatin page lists 90 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), Acerola (moderate) and Active Hexose Correlated Compound (ahcc) (moderate).

From our pharmacist’s overview on the Cisplatin page

“Kidney damage is the risk I would flag first for anyone receiving cisplatin (Platinol-AQ). Cisplatin is a chemotherapy drug that already stresses the kidneys, and two of the three major-rated interactions on this list, Siberian cocklebur and asarabacca, involve herbs that can injure the kidneys on their own, stacking harm on an organ t…”

About Bayberry

What is Bayberry?

Bayberry
  • Diarrhea and digestive upset
  • Sore throat and cold symptoms
  • Gum and mouth rinse (gargle)
  • Skin and wound care
  • General "astringent" tonic

Bayberry is a traditional herb used mainly as an astringent for diarrhea, sore throats, and minor skin or gum problems, but there is very little modern human research to confirm it works. Its bark contains tannins and other compounds that may cause stomach upset and could be harmful in large amounts. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Morella cerifera · Myricaceae · Root bark, leaves, and stem bark; berries (for wax) · Dried root bark, powder, capsules, tea, tincture, and topical preparations

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

Bayberry: dosing

There is no well-established or standardized dose for bayberry. Because human studies are lacking, no reliable "safe and effective" amount has been set.If you choose to use a bayberry product, follow the directions on the product label and do not exceed the suggested amount.

About Cisplatin Injection

What Is Cisplatin Injection Used For?

Brand name: Platinol-AQ

Cisplatin Injection is used to treat three types of cancer. For metastatic testicular tumors and metastatic ovarian tumors, it is used as part of combination chemotherapy — alongside other approved cancer medicines — in patients who have already had surgery and/or radiation therapy. For metastatic ovarian tumors, it can also be used alone as a second-line treatment when standard chemotherapy has stopped working and cisplatin has not been tried before.

For advanced bladder cancer (specifically transitional cell bladder cancer) that can no longer be treated with surgery or radiation, Cisplatin Injection is used as a single agent.

Most-Reported Side Effects for Cisplatin

From FAERS, the FDA’s public side-effect reporting system (77,669 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 5,437 reports
Neutropenia 4,877 reports
Disease progression 4,657 reports
Febrile neutropenia 4,606 reports
Vomiting 4,566 reports

Taking Bayberry and Cisplatin Together: Common Questions

Is it safe to take Bayberry with Cisplatin?
We do not list a known interaction between Bayberry and Cisplatin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Bayberry and Cisplatin have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Cisplatin interact with any supplements?
Yes. Cisplatin has documented interactions with 90 supplements in our database — Bayberry is not one of them. The Cisplatin interaction page linked on this page lists every one, ranked by severity.
