No Known Interaction
The bottom line No known interaction

We found no known interaction between Gumweed and Disulfiram 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.

Gumweed and Disulfiram

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 Disulfiram and Gumweed 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 Gumweed at all — not against Disulfiram, 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 Gumweed Itself Has Been Linked To

This is not an interaction — nothing below involves Disulfiram. It is the side-effect record for Gumweed on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Gumweed, this list is the first place to look.

  • Diarrhea Additional detail

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

About Gumweed

What is Gumweed?

  • Cough and bronchitis
  • Asthma-related breathing problems
  • Skin irritation from poison ivy or poison oak
  • Minor wounds and rashes
  • Upper respiratory congestion

Gumweed is a traditional North American plant used mostly for coughs, chest congestion, and skin irritation such as poison ivy rashes. Good-quality human studies are lacking, so its benefits are not well proven, and it should be used cautiously and avoided during pregnancy and breastfeeding.

Grindelia robusta · Asteraceae · Dried leaves and flowering tops · Tea, tincture, liquid extract, capsules, topical preparations

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

Gumweed: dosing

There is no well-established, standardized dose for gumweed. Traditional preparations include teas, tinctures, and liquid extracts, but the strength of commercial products varies widely.The safest approach is to follow the directions on the product label and not exceed the suggested amount.

About Disulfiram

What Is Disulfiram Used For?

Brand name: Antabuse

Disulfiram is used as part of a treatment program for people with chronic alcoholism who want to stop drinking. It works by making the body react very unpleasantly to alcohol, which helps reinforce the commitment to stay sober.

It is not a cure for alcoholism, and it works best when combined with counseling, motivation, and support. Used alone, without those supports, it is unlikely to make a lasting difference.

Most-Reported Side Effects for Disulfiram

From FAERS, the FDA’s public side-effect reporting system (1,124 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 83 reports
Toxicity to various agents 64 reports
Nausea 52 reports
Confusional state 48 reports
Drug abuse 44 reports
