BOTANICAL IDENTITY
The right name is the first step.
Also known as: Restharrow
Check the scientific name and the part used; a photograph is not sufficient for foraging plants intended for consumption.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
01 · UNDERSTAND
Properties & uses.
Urinary elimination
Traditional use to increase urine output in minor urinary complaints.
Read the sourceThe traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.
02 · UNDERSTAND THE ACTION
How does the plant act?
Spiny restharrow is documented through its root. Its traditional use aims to increase urine output as an adjunct in minor urinary problems. Older animal experiments make diuretic activity plausible, but their heterogeneous protocols and small samples do not allow prediction of an infusion's effect in a person. “Traditionally promotes urine output” must therefore be separated from “treats an infection” or “dissolves a stone”.
Support for urinary elimination
The root in an aqueous preparation falls within the traditional scope of increasing urine output, with appropriate fluid intake. This use requires that there be no medical fluid restriction.
Read the referenceDiuresis in animal models
Some older experiments on aqueous root extracts observed increased urine output. They do not characterize a predictable human response.
Read the referenceWhat this means for preparation.
Look for the word root and do not substitute an aerial part or a mixture with unknown components. A urinary herbal tea must not delay consultation for fever, significant pain or blood in the urine.
03 · EXAMINE THE EVIDENCE
What the research shows.
A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.
Old and weak pharmacological evidence
- Type of research
- Rat or rabbit studies examined in the EMA report.
- Preparation concerned
- Aqueous Ononis spinosa root extracts administered orally.
- Observed results
- Effects on diuresis have been reported in some protocols.
- Limitations to consider
- Sample sizes were sometimes very small, methods varied and comparisons were difficult. These studies do not measure clinical benefit in a urinary tract infection.
What can we take from this?
The constituent responsible for a possible therapeutic effect is not established here. The dossier does not support claims of antibiotic action, proven prevention of recurrence or dissolution of stones.

Precautions & contraindications.
This guidance does not cover every individual situation. Missing information is not a guarantee of safety.
Contraindications
- Allergy to restharrow.
- Do not use if fluid restriction is prescribed, particularly for severe heart or kidney disease.
Medicine interactions
- No established interaction is included in this entry; this does not guarantee compatibility with a treatment.
Adverse effects
- Adverse effects insufficiently documented in the sources used here.
Pregnancy & breastfeeding
Pregnancy and breastfeeding: medicinal use is not recommended because of insufficient data.
Children & adolescents
