Eschscholziae herba

California poppy is the common name for the above-ground parts of the plant Eschscholzia californica Cham. The plant is cultivated or gathered when flowering to obtain the above-ground parts for medicinal use.

California poppy preparations are obtained by powdering the dried above-ground parts of the plant.

Herbal medicines containing California poppy are usually available in solid forms to be taken by mouth.

The HMPC concluded that, on the basis of its long-standing use, California poppy can be used for the relief of mild symptoms of mental stress and to aid sleep.

California poppy preparations 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 instruction on how to take California poppy 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 California poppy medicines to relieve mild symptoms of mental stress and to aid sleep 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 conclusions on the use of California poppy medicines are based on their long-standing use. In its assessment, the HMPC also considered a few available clinical studies, including a study in patients suffering from sleep disorders, which suggested a positive effect on sleep. For detailed information on the studies assessed by the HMPC, see the HMPC assessment report.

At the time of the HMPC assessment, no side effects had been reported with these medicines.
