Masterwort and Clevidipine

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 Clevidipine and Masterwort 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.

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.

How we checked

Why No Interaction Is Listed for Clevidipine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Clevidipine is filed under a single classification — antihypertensive drugs. Masterwort has documented interactions with 1 drug class — the most serious being photosensitizing drugs (moderate) — and none of Clevidipine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Clevidipine page

“When you are on clevidipine (Cleviprex), a hospital IV drip used to bring dangerously high blood pressure down fast, every one of the 119 supplements and herbs listed here pushes on the very thing the drug controls, and that earns this list real caution. Most of the 104 moderate entries, everyday products like fish oil among them, add…”

About Masterwort

What is Masterwort?

Masterwort
  • Digestive upset
  • Mild anxiety and tension
  • Skin complaints
  • Respiratory and cough relief
  • Traditional tonic

Masterwort (Heracleum sphondylium), a plant in the carrot family, has a long folk-medicine history for digestion, nerves, and skin. Modern scientific evidence to support these uses is very limited, and the plant can cause skin reactions to sunlight, so use it cautiously and talk with your pharmacist or doctor first.

Heracleum sphondylium · Apiaceae · Root, leaves, seeds, and aerial parts · Tea, tincture, dried herb, essential oil

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