Overview
This is a summary of the scientific conclusions reached by the Committee on Herbal Medicinal Products (HMPC) on the medicinal uses of primula flower. The HMPC conclusions are taken into account by EU Member States when evaluating applications for the licensing of herbal medicines containing primula flower.
This summary is not intended to provide practical advice on how to use medicines containing primula flower. For practical information about using primula flower medicines, patients should read the package leaflet that comes with the medicine or contact their doctor or pharmacist.
Primula flower is the common name for the flowers of the plant Primula veris L. and/or Primula elatior (L.) Hill.
The HMPC conclusions only cover primula flower preparations which are obtained by comminuting (reducing into tiny pieces) the flowers or using a technique to extract compounds by putting the plant material in a solvent (such as ethanol) to dissolve compounds and form a liquid extract.
Herbal medicines containing these primula flower preparations are usually available as herbal tea to be drunk and in liquid forms to be taken by mouth.
Primula flower preparations 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 primula flower primula flower preparations can be used as an expectorant (a medicine that helps bring up phlegm) for coughs associated with colds.
Primula flower medicines should only be used in adults and adolescents over the age of 12 years. If symptoms last longer than one week or worsen during the use of the medicine, a doctor or a qualified healthcare practitioner should be consulted. Detailed instructions on how to take primula flower 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 primula flower medicines for 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 primula flower increased production of airway secretions, making phlegm less thick and easier to expel. No clinical studies have been carried out with primula flower.
For detailed information on the studies assessed by the HMPC, see the HMPC assessment report.
Primula flower medicines must not be used in patients who are allergic to primula flower or to other plants of the primula species. Allergic reactions have been reported with these medicines.
Further information on the risks associated with these primula flower 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 primula flower 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 primula flower medicines in EU Member States should be obtained from the relevant national authorities.
