No Known Interaction
The bottom line No known interaction

We found no known interaction between Wild Daisy and Hydroxyurea 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.

Wild Daisy and Hydroxyurea

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 Hydroxyurea 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 Hydroxyurea, 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 Hydroxyurea’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 Hydroxyurea’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. 6 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • Anemia Worth acting on mentioned in 12.0% of FDA reports for Hydroxyurea
  • A low platelet count Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on
  • Changes to your period
  • Dry skin
  • Weight gain
  • Pain in an arm or leg

Showing the 10 most notable of 25 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 Hydroxyurea. Read the label on DailyMed › Where a percentage is shown, it is the share of 21,027 voluntary FDA FAERS reports for Hydroxyurea 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.

See Every Supplement That Interacts With Hydroxyurea

This page covers Wild Daisy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Hydroxyurea page lists 18 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 10 minor.

From our pharmacist’s overview on the Hydroxyurea page

“People take hydroxyurea (Droxia, Hydrea, Siklos, Xromi) for serious reasons, most often sickle cell disease or certain blood cancers, and it only works if a steady dose reaches the bloodstream. That is exactly what nearly all 18 supplements listed here can undermine, so this page earns real vigilance rather than a skim.”

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 13, 2026. The Wild Daisy and Hydroxyurea 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.

Wild Daisy: dosing

There is no established, standardized dose for wild daisy. Because it has not been well studied in people, safe and effective amounts are not known.If you choose to use a product, follow the directions on the label and do not exceed them.
