The bottom line No known interaction

We found no known interaction between Bogbean and Tadalafil 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.

Bogbean and Tadalafil

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 Tadalafil and Bogbean 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 Bogbean at all — not against Tadalafil, 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

What Bogbean Itself Has Been Linked To

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

  • Diarrhea / Vomiting / Nausea Additional detail

    “Orally, bogbean seems to be generally well tolerated (4). Excessive doses of bogbean can irritate the GI tract, and cause diarrhea, pain, nausea, and vomiting (4).”

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

Everything else you take

See Every Supplement That Interacts With Tadalafil

This page covers Bogbean only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tadalafil page lists 144 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Mistletoe (major), Grapefruit (major), Hawthorn (major) and St. John's Wort (major).

By severity: 5 major · 98 moderate · 41 minor.

From our pharmacist’s overview on the Tadalafil page

“Grapefruit juice is the first thing to know about if you take tadalafil (Cialis, Tadliq). It blocks CYP3A4, the enzyme that clears the drug, so blood levels climb and side effects like a steep drop in blood pressure become more likely.”

About Bogbean

What is Bogbean?

  • Rheumatoid arthritis and joint pain
  • Poor appetite and digestive upset
  • Bitter tonic
  • Scurvy (traditional)
  • Fever (traditional)

Bogbean is a wetland plant whose bitter leaves have long been used in folk medicine for joint pain, poor appetite, and digestion. Good-quality human studies are lacking, so its benefits are unproven, and large amounts can upset the stomach. Talk with a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Menyanthes trifoliata · Menyanthaceae · Leaves (and sometimes the roots/rhizome) · Tea, tincture, liquid extract, capsules, dried herb

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

Bogbean: dosing

There is no well-established, standardized dose for bogbean. Traditional use typically involves small amounts of the dried leaf as a tea or a measured dose of tincture or extract.Because strengths vary widely between products, the safest approach is to follow the directions on the product label and not exceed the recommended amount. More is not better with this bitter herb, since larger doses are more likely to cause stomach upset.
