Anisi fructus

Aniseed is the common name for the fruit of the plant Pimpinella anisum L.

The HMPC conclusions only cover the dried herbal substance (dried aniseed) and aniseed preparations which are obtained by drying and comminuting (reducing into tiny pieces) or crushing the fruit.

These aniseed medicines are usually available as herbal tea to be drunk.

These aniseed medicines may also be found in combination with other herbal substances in some herbal medicines. These combinations are not covered in this summary.

The HMPC concluded that, on the basis of its long-standing use, these aniseed medicines can be used for treating symptoms of mild indigestion complaints including bloating and flatulence. In addition, they can be used as an expectorant (a medicine that helps bring up phlegm) for coughs associated with colds.

Aniseed medicines should only be used in adults and adolescents over the age of 12 years and should not be taken for longer than two weeks. If symptoms last or get worse during the use of the medicine, a doctor or a qualified health care practitioner should be consulted. Detailed instructions on how to take aniseed 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 these aniseed medicines for indigestion complaints and coughs 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.

In its assessment, the HMPC considered laboratory studies which showed aniseed preparations to have a relaxant effect on muscles of the gut and airways.

For detailed information on the studies assessed by the HMPC, see the HMPC assessment report.

Aniseed medicines must not be used in patients who are allergic to aniseed or to plants of the Apiaceae family (Umbelliferae) (caraway, celery, coriander, dill, fennel) or anethole. Allergic reactions to aniseed that affect the skin or airways may occur.

Further information on the risks associated with these aniseed medicines, including the appropriate precautions for their safe use, can be found in the monograph under the tab 'All documents'.

Any applications for the licensing of medicines containing aniseed have to be submitted to the national authorities responsible for medicinal products, which will assess the application for the herbal medicine and take into account the scientific conclusions of the HMPC.

Information on the use and licensing of aniseed medicines in EU Member States should be obtained from the relevant national authorities.
