Drug & supplement interaction

Spanish Broom + Rosuvastatin

Rosuvastatin brand names: Crestor, Ezallor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Spanish Broom and Rosuvastatin 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Spanish Broom and Rosuvastatin

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 Rosuvastatin and Spanish Broom 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 Spanish Broom at all — not against Rosuvastatin, 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

No Interaction Found — But Data Suggests Spanish Broom and Rosuvastatin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Confusion Worth acting on Additional detail

    Spanish Broom

    “Ingestion of Spanish broom flowers or seeds collected directly from the plant has been associated with cases of sedation, confusion, dizziness, headache, agitation, and tremors. In children aged 5-6 years, these symptoms occurred after ingesting 4-8 seeds, with the severity of the effects appearing to be dose-dependent.”

From our pharmacist’s overview on the Rosuvastatin page

“Rosuvastatin (Crestor, Ezallor) is a statin taken daily for years to lower cholesterol, and its supplement list deserves real scrutiny, not a quick skim. Five of the 63 ingredients on file carry a major rating, headed by grapefruit, which can raise statin blood levels, and by heavy drinking, since beer and wine compound the strain this…”

About Spanish Broom

What is Spanish Broom?

  • Diuretic ('water pill') effect
  • Heart and circulation complaints (folk use)
  • Mild laxative
  • Fragrance in perfumes and cosmetics
  • Traditional fiber and dye source

Spanish Broom is a Mediterranean flowering shrub used historically as a diuretic and heart remedy and today mostly as a perfume ingredient. It contains toxic alkaloids that can affect the heart and nervous system, and there is no reliable modern evidence that it is safe or effective for any health condition. Because of the poisoning risk, it is best avoided as an oral supplement.

Spartium junceum · Fabaceae · Flowers, and sometimes the flowering tops and seeds · Traditional teas or infusions, tinctures, and an essential oil (absolute) used in perfumery; rarely sold as a standardized supplement

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

Spanish Broom: dosing

There is no established safe dose for Spanish Broom as a supplement, and it is not recommended for internal use. Because the plant is toxic and its alkaloid content varies, no reliable, safe amount can be given.We do not provide a dose for this plant.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis).

In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked. Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.

Most-Reported Side Effects for Rosuvastatin

From FAERS, the FDA’s public side-effect reporting system (229,715 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 14,778 reports
Nausea 12,432 reports

Taking Spanish Broom and Rosuvastatin Together: Common Questions

Is it safe to take Spanish Broom with Rosuvastatin?
We do not list a known interaction between Spanish Broom and Rosuvastatin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Spanish Broom and Rosuvastatin have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Rosuvastatin interact with any supplements?
Yes. Rosuvastatin has documented interactions with 63 supplements in our database — Spanish Broom is not one of them. The Rosuvastatin interaction page linked on this page lists every one, ranked by severity.
