Drug & supplement interaction

Skunk Cabbage + Belumosudil Mesylate

Belumosudil Mesylate brand name: Rezurock.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Skunk Cabbage and Belumosudil Mesylate 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 label for Belumosudil Mesylate states a food rule worth keeping to, and 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

Skunk Cabbage and Belumosudil Mesylate

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 Belumosudil Mesylate and Skunk Cabbage 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 Skunk Cabbage at all — not against Belumosudil Mesylate, 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 Skunk Cabbage and Belumosudil Mesylate 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.

How to take them

Some Belumosudil Mesylate Products Have a Food Rule — Skunk Cabbage Should Not Break It

At least one FDA label for a product containing Belumosudil Mesylate says to take it with food. If you take Skunk Cabbage on an empty stomach out of habit, keep them separate — and take Belumosudil Mesylate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Belumosudil Mesylate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION Recommended Dosage : 200 mg taken orally once daily with food.

From the Dosage and Administration section of the FDA label we read for Belumosudil Mesylate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Skunk Cabbage

What is Skunk Cabbage?

Skunk Cabbage
  • Cough and bronchitis
  • Asthma and respiratory complaints
  • Skin problems and wounds (poultice)
  • Inflammation
  • Nerve and muscle complaints

Skunk cabbage is a North American plant with a long history of traditional use for breathing and skin problems, but there is very little modern scientific evidence to support these uses or to confirm it is safe. The fresh plant contains sharp calcium oxalate crystals that can cause intense burning and irritation. Because safety is poorly understood, talk with a pharmacist or doctor before using it.

Symplocarpus foetidus · Araceae · Root (rhizome) and sometimes the leaves · Dried root, tincture, extract, poultice; rarely capsules or tea

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

Skunk Cabbage: dosing

There is no established or standardized dose for skunk cabbage. Traditional preparations varied widely, and there is not enough modern research to recommend a safe and effective amount.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

Taking Skunk Cabbage and Belumosudil Mesylate Together: Common Questions

Is it safe to take Skunk Cabbage with Belumosudil Mesylate?
We do not list a known interaction between Skunk Cabbage and Belumosudil Mesylate. 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 Skunk Cabbage and Belumosudil Mesylate have any of the same side effects?
Yes — our sources link each of them separately to 6 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.
Should I take Skunk Cabbage and Belumosudil Mesylate at the same time of day?
At least one FDA label for a product containing Belumosudil Mesylate says to take it with food. If you take Skunk Cabbage on an empty stomach out of habit, keep them separate and take Belumosudil Mesylate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Belumosudil Mesylate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Belumosudil Mesylate interact with any supplements?
Yes. Belumosudil Mesylate has documented interactions with 138 supplements in our database — Skunk Cabbage is not one of them. The Belumosudil Mesylate interaction page linked on this page lists every one, ranked by severity.
