The bottom line No known interaction

We found no known interaction between Columbine and Simvastatin 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.

Columbine and Simvastatin

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 Simvastatin and Columbine 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 Columbine at all — not against Simvastatin, 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.

Columbine safety at a glance

Columbine overall Avoid Parts of the plant—especially seeds and roots—can be toxic, and safe use is not established.
Pregnancy Avoid Not enough safety data and potential toxicity make use during pregnancy unsafe.
Breastfeeding Avoid Safety has not been studied, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

What Simvastatin’s Own FDA Label Lists

This is not an interaction — none of it involves Columbine. These are the most notable effects listed in the ADVERSE REACTIONS section of Simvastatin’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • A heart attack Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • High blood sugar Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on

Showing the 10 most notable of 41 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Simvastatin. Read the label on DailyMed › Where a percentage is shown, it is the share of 261,345 voluntary FDA FAERS reports for Simvastatin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Columbine’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Columbine side to compare — that is a limit of the record, not a statement that Columbine has no side effects.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Columbine is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Columbine reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Columbine and Simvastatin records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Columbine

What is Columbine?

  • Skin sores and rashes (traditional)
  • Sore throat and mouth irritation (traditional)
  • Minor wounds (traditional, topical)
  • General folk remedy

Columbine is a flowering plant once used in traditional folk medicine, but there is very little modern scientific evidence that it works for any health condition. It belongs to the buttercup family, which contains potentially toxic compounds, so it is not recommended as a supplement and the seeds and roots in particular can be poisonous. If you are considering any herbal product, talk with your pharmacist or doctor first.

Aquilegia vulgaris · Ranunculaceae · Flowers, leaves, and root (used historically) · Rarely used today; historically prepared as teas, poultices, or tinctures

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

Columbine: dosing

There is no established or recommended dose for columbine. It is not a standard supplement, and safe amounts have not been determined through scientific study.Because of its potential toxicity, we do not recommend taking columbine. If you come across a product that contains it, follow the product label only after checking with a pharmacist or doctor, and do not exceed any directions given.

About Simvastatin

What Is Simvastatin Used For?

Brand name: Zocor

Simvastatin tablets are used alongside a cholesterol-lowering diet to treat high LDL cholesterol (bad cholesterol), high triglycerides, and certain inherited cholesterol disorders, including heterozygous familial hypercholesterolemia (HeFH) in adults and children aged 10 and older, and homozygous familial hypercholesterolemia (HoFH) in adults.

In adults who already have coronary heart disease, cerebrovascular disease, peripheral vascular disease, or diabetes and are at high risk for heart events, simvastatin is also used to reduce the risk of death from heart disease, non-fatal heart attack, stroke, and the need for procedures to open blocked arteries. Zocor is one brand-name product containing simvastatin and carries these same indications.

Most-Reported Side Effects for Simvastatin

From FAERS, the FDA’s public side-effect reporting system (263,006 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 14,524 reports
Nausea 14,119 reports
Dyspnea 13,226 reports
Diarrhea 12,591 reports
Dizziness 11,830 reports
