European Five-finger Grass and Terconazole

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 Terconazole and European Five-finger Grass 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 European Five-finger Grass at all — not against Terconazole, 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

What Terconazole’s Own FDA Label Lists

This is not an interaction — none of it involves European Five-finger Grass. These are the most notable effects listed in the ADVERSE REACTIONS section of Terconazole’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.

  • Sun sensitivity
  • Fever
  • Itching
  • Stomach pain
  • Headache mentioned in 5.5% of FDA reports for Terconazole

From the ADVERSE REACTIONS section of the FDA label for Terconazole. Read the label on DailyMed › Where a percentage is shown, it is the share of 805 voluntary FDA FAERS reports for Terconazole that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. European Five-finger Grass’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no European Five-finger Grass side to compare — that is a limit of the record, not a statement that European Five-finger Grass has no side effects.

Everything else you take

See Every Supplement That Interacts With Terconazole

This page covers European Five-finger Grass only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Terconazole page lists 20 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 · 12 minor.

From our pharmacist’s overview on the Terconazole page

“Terconazole (Terazole) is a vaginal antifungal for yeast infections, and its supplement list earns genuine caution because of one standout: activated charcoal, the only major-rated interaction among the 20 on file. Charcoal binds many medicines and can lower their levels even when a drug is not taken by mouth, which makes it the entry…”

About European Five-finger Grass

What is European Five-finger Grass?

European Five-finger Grass
  • Diarrhea
  • Sore throat and mouth rinse
  • Skin irritation
  • Mild inflammation
  • Digestive upset

European Five-finger Grass (Potentilla reptans) is a traditional European herb used mainly for diarrhea, sore throat, and minor skin problems, largely because of its tannin content. There is very little high-quality human research to confirm it works for any condition, so use it cautiously and talk to your pharmacist or doctor first.

Potentilla reptans · Rosaceae · Leaves, flowers, and roots (aerial parts and rhizome) · Tea, liquid extract, tincture, dried herb, topical preparations

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

European Five-finger Grass: dosing

There is no standardized, scientifically established dose for European Five-finger Grass. Traditional use most often involved a tea made from the dried leaves or roots, but exact amounts varied widely.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount. Because product strength can vary a lot between brands, it is wise to start low.

About Terconazole

What Is Terconazole Used For?

Brand name: Terazole

Terconazole vaginal cream and vaginal suppositories are both indicated for the local treatment of vulvovaginal candidiasis — commonly known as a vaginal yeast infection caused by Candida species. Because these products only work against Candida, a healthcare provider should confirm the diagnosis before or during treatment.

Before starting a second course of treatment with terconazole vaginal suppositories, the diagnosis should be re-confirmed by lab tests and other possible causes of symptoms should be ruled out.
