Pilosellae herba cum radice

Mouse-ear hawkweed is the common name for the above-ground parts (which may include flowers) and parts of the root of the plant Hieracium pilosella L. The plant is cultivated or gathered to obtain the plant parts for medicinal use.

Mouse-ear hawkweed preparations are obtained by comminuting (reducing into tiny pieces) or powdering the dried plant parts.

Herbal medicines containing mouse-ear hawkweed are usually available as a herbal tea to be drunk and in solid forms to be taken by mouth.

The HMPC concluded that, on the basis of its long-standing use, mouse-ear hawkweed can be used as a mild diuretic (a medicine to increase production of urine) for the relief of minor problems of the urinary tract (the structures that carry urine).

Mouse-ear hawkweed should only be used in adults. If symptoms last longer than two weeks during treatment, a doctor or a qualified healthcare practitioner should be consulted. Detailed instructions on how to take mouse-ear hawkweed medicines and who can use them can be found in the package leaflet that comes with the medicine.

The HMPC conclusions on the use of mouse-ear hawkweed medicines for the relief of minor urinary problems are based on their 'traditional use'. This means that, although there is insufficient evidence from clinical trials, the effectiveness of these herbal medicines is plausible and there is evidence that they have been used safely in this way for at least 30 years (including at least 15 years within the EU). Moreover, the intended use does not require medical supervision.

The HMPC noted the lack of clinical studies with mouse-ear hawkweed, but took into account the well documented use of this herbal medicine for the above uses. For further information, see the HMPC assessment report.

Mouse-ear hawkweed medicines are generally well tolerated. At the time of the HMPC assessment, no side effects had been reported with these medicines.

Mouse-ear hawkweed medicines must not be used in patients with conditions in which a reduced fluid intake is recommended (such as severe heart or kidney disease).
