Field Scabious and Losartan Potassium

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 Losartan Potassium and Field Scabious 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 Field Scabious at all — not against Losartan Potassium, 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.

  • Severe muscle breakdown Worth acting on
  • Muscle weakness Worth acting on
  • High potassium Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Losartan Potassium. Read the label on DailyMed › Where a percentage is shown, it is the share of 89,498 voluntary FDA FAERS reports for Losartan Potassium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Field Scabious’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Field Scabious side to compare — that is a limit of the record, not a statement that Field Scabious 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. Field Scabious 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 Field Scabious reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The Field Scabious and Losartan Potassium 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 Field Scabious

What is Field Scabious?

  • Skin conditions like eczema and minor wounds
  • Cough and chest complaints
  • Sore throat
  • Mild digestive upset
  • Traditional 'blood cleansing' remedies

Field Scabious is a wild-growing herb used in European folk medicine, mostly for skin problems, coughs, and sore throats. There is very little modern scientific research to confirm any of these uses, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Knautia arvensis · Caprifoliaceae · Aerial parts (flowers, leaves, and stems), occasionally the root · Tea (infusion), tincture, dried herb, topical washes or compresses

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

Field Scabious: dosing

There is no established, standardized dose for Field Scabious. It has traditionally been prepared as a tea from the dried aerial parts or as a tincture, but reliable dosing guidelines from clinical research do not exist.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Losartan

What Is Losartan Used For?

Brand name: Cozaar

Losartan treats high blood pressure (hypertension) in adults and children 6 years and older. Keeping blood pressure under control lowers the risk of serious events like stroke and heart attack.

It is also used to reduce the risk of stroke in people who have high blood pressure and left ventricular hypertrophy (an enlarged heart muscle). Note: evidence suggests this stroke-risk benefit may not apply to Black patients. Additionally, losartan treats diabetic nephropathy — kidney damage caused by type 2 diabetes — in people who also have high blood pressure.
