Drug & supplement interaction

Skunk Cabbage + Ospemifene

Ospemifene brand name: Osphena.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Skunk Cabbage and Ospemifene 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 Ospemifene 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.

Skunk Cabbage and Ospemifene

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 Ospemifene 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 Ospemifene, 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 Ospemifene 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.

Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

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

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

One tablet taken orally once daily with food.

From the Dosage and Administration section of the FDA label we read for Ospemifene — 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.

See Every Supplement That Interacts With Ospemifene

This page covers Skunk Cabbage only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ospemifene page lists 155 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Tiratricol (major) and Acacia Rigidula (moderate).

By severity: 4 major · 112 moderate · 39 minor.

From our pharmacist’s overview on the Ospemifene page

“Women prescribed ospemifene (Osphena) for painful intercourse after menopause are often the same women reaching for St. John's wort for mood or grapefruit juice at breakfast, and both sit among the four major-rated interactions on this page, so the list deserves genuine care.”

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 Ospemifene Together: Common Questions

Is it safe to take Skunk Cabbage with Ospemifene?
We do not list a known interaction between Skunk Cabbage and Ospemifene. 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 Ospemifene 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.
Should I take Skunk Cabbage and Ospemifene at the same time of day?
At least one FDA label for a product containing Ospemifene says to take it with food. If you take Skunk Cabbage on an empty stomach out of habit, keep them separate and take Ospemifene with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Ospemifene products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Ospemifene interact with any supplements?
Yes. Ospemifene has documented interactions with 155 supplements in our database — Skunk Cabbage is not one of them. The Ospemifene interaction page linked on this page lists every one, ranked by severity.
