Wild Daisy and Fulvestrant

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 Fulvestrant and Wild Daisy 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 Wild Daisy at all — not against Fulvestrant, 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 Fulvestrant’s Own FDA Label Lists

This is not an interaction — none of it involves Wild Daisy. These are the most notable effects listed in the ADVERSE REACTIONS section of Fulvestrant’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. 4 of them are worth acting on rather than waiting out — marked below.

  • Shortness of breath Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • An allergic reaction Worth acting on
  • Pain in an arm or leg
  • Back pain
  • Tiredness mentioned in 12.7% of FDA reports for Fulvestrant
  • Numbness or tingling
  • Cough
  • Joint pain

Showing the 10 most notable of 16 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 Fulvestrant. Read the label on DailyMed › Where a percentage is shown, it is the share of 32,843 voluntary FDA FAERS reports for Fulvestrant that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wild Daisy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Wild Daisy side to compare — that is a limit of the record, not a statement that Wild Daisy 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. Wild Daisy 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 Wild Daisy reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Wild Daisy and Fulvestrant 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 Wild Daisy

What is Wild Daisy?

Wild Daisy
  • Bruises and minor wounds
  • Inflammation and swelling
  • Coughs and respiratory complaints
  • Digestive upset
  • Fluid retention ('water pill')
  • Skin conditions

Wild daisy (Bellis perennis) is a traditional European herb used mainly for bruises, minor wounds, and inflammation, but high-quality human evidence for any use is lacking. It is generally considered low-risk when used briefly on the skin, but people allergic to ragweed and related plants should be cautious, and it is best avoided in pregnancy and breastfeeding due to limited safety data.

Bellis perennis · Asteraceae · Flowers and leaves (sometimes the whole flowering plant) · Tea, tincture, topical ointment or cream, homeopathic preparations, dried herb

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

Fulvestrant injection combined with ribociclib may also be used as an initial hormone-based treatment in this setting.
