The bottom line No known interaction

We found no known interaction between Black Bryony and Umeclidinium Bromide 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.

Black Bryony and Umeclidinium Bromide

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 Umeclidinium Bromide and Black Bryony 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 Black Bryony at all — not against Umeclidinium Bromide, 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.

Everything above comes from the Natural Medicines adverse-effect record for Black Bryony — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Umeclidinium Bromide’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Umeclidinium Bromide column appears here.

From our pharmacist’s overview on the Umeclidinium Bromide page

“Umeclidinium bromide (Incruse Ellipta) keeps COPD airways open by blocking acetylcholine, and that mechanism is exactly where most of this list presses. Roughly two thirds of the flagged supplements act on the same pathway, either stacking anticholinergic side effects such as dry mouth and constipation, or working against the drug and…”

About Black Bryony

What is Black Bryony?

Black Bryony
  • Bruises and sprains (applied to the skin)
  • Joint and muscle pain
  • Chilblains
  • Rheumatic complaints
  • Skin and folk "healing" remedies

Black Bryony is a toxic climbing plant whose root has been used in folk medicine, mostly applied to the skin for bruises and aches. There is little to no reliable scientific evidence that it works, and it can cause serious poisoning if swallowed or severe irritation on the skin. Because of these real risks, it is best avoided, especially without guidance from a healthcare professional.

Dioscorea communis · Dioscoreaceae · Root (tuber); occasionally berries and aerial parts (all considered toxic) · Traditional poultices and ointments for external use; rarely sold as a modern supplement

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

Black Bryony: dosing

There is no established safe dose for Black Bryony. It has not been studied well enough to recommend any amount, and because it is toxic, no standard dose exists for taking it by mouth.If you ever encounter a product that contains it, do not assume it is safe. Given the risks, the safest approach is not to use it at all.

About Umeclidinium Oral Inhalation

What Is Umeclidinium Oral Inhalation Used For?

Brand name: Incruse Ellipta

Umeclidinium Ellipta and Umeclidinium ELLIPTA (generic) are indicated for the maintenance treatment of COPD (chronic obstructive pulmonary disease) in adults. This means it is used every day on a regular schedule to help keep airways open and reduce COPD symptoms over time.

This medication is not a rescue inhaler. It will not treat a sudden flare-up or acute bronchospasm. A separate short-acting inhaler is needed for those situations.
