The bottom line No known interaction

We found no known interaction between Cardamom and Riociguat 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.

Cardamom and Riociguat

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 Riociguat and Cardamom 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 Cardamom at all — not against Riociguat, 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 Cardamom Itself Has Been Linked To

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

  • A skin rash Additional detail

    “Orally, mild skin inflammation due to cardamom has been reported in one participant of a clinical trial. Topically, a case report describes chronic hand dermatitis in a confectioner frequently exposed to cardamom. Skin patch tests were positive for cardamom, and for terpenoids present in the seeds.”

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

Overlapping uses

What Riociguat Is Prescribed For, and What Cardamom Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Riociguat is a prescription medicine with approved uses on its FDA label. Cardamom is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Riociguat is prescribed for: Riociguat tablets — sold as Adempas and under the generic name Riociguat — are used to treat adults with two types of pulmonary hypertension (high blood pressure in the lungs). The first is chronic thromboembolic pulmonary hypertension (CTEPH), a condition caused by blood clots in the lung arteries, either after surgery or when surgery is not an option. The second is pulmonary arterial hypertension (PAH), where the arteries carrying blood to the lungs are narrowed or blocked. In both conditions, riociguat helps improve exercise ability and functional status, and in PAH it also helps slow the disease from getting worse.

Cardamom has been studied for:

  • Hypertension studied, not established Cardamom has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Cardamom for hypertension

    It is unclear if oral cardamom powder is beneficial in patients with hypertension.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Riociguat on your own; if you are taking Cardamom for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Riociguat

This page covers Cardamom only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Riociguat page lists 230 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 6 major · 187 moderate · 37 minor.

From our pharmacist’s overview on the Riociguat page

“Riociguat (Adempas) works by relaxing the blood vessels in your lungs, which also lowers blood pressure, so I read this list of 230 supplements and herbs with real concern, and the six rated major are what to understand first. Grapefruit can push riociguat levels up and intensify its effect, while St.”

About Cardamom

What is Cardamom?

  • Digestive upset and bloating
  • Bad breath
  • Nausea
  • Flavoring in food and drinks
  • General antioxidant support

Cardamom is a popular cooking spice that has long been used in traditional medicine for digestion and fresh breath. As a food, it is generally safe for most people, but high-dose supplements have not been well studied, so the health benefits remain mostly unproven. If you want to use concentrated cardamom products, check with your pharmacist or doctor first.

Elettaria cardamomum · Zingiberaceae · Seeds (from the dried fruit pods) and essential oil · Whole pods, ground spice, tea, capsules, extracts, and essential oil

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

Cardamom: dosing

There is no official or standardized medicinal dose for cardamom. As a spice, people use it freely in cooking, which is considered safe.For supplements, capsules, or extracts, the right amount varies by product, and a proven effective dose has not been established. The safest approach is to follow the directions on the product label and not exceed them.
