Corn Poppy

Papaver rhoeas
Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.
Do not confuse with the opium poppy (Papaver somniferum), which is richer in potent alkaloids; the corn poppy contains low amounts but caution is still required. Not recommended for pregnant or breastfeeding women or for young children without advice from a healthcare professional. Avoid combining with sedatives, sleeping medications, or central nervous system depressants. Harvest only properly identified petals, avoiding any confusion with other wild poppies.
Infusion — Flowers (petals)

Soothing evening infusion

Pour simmering water over dried petals and let steep covered for about ten minutes. Strain before drinking warm, preferably in the evening. One teaspoon of dried petals per cup, once or twice daily.

Decoction — Flowers (petals)

Decoction for compress use

Gently boil the petals for a few minutes then let cool. Soak a clean compress and apply to the affected area. Professional advice is recommended before any regular use on fragile or irritated skin. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.

Syrup — Flowers (petals)

Traditional corn poppy syrup

Fresh petals were traditionally macerated then mixed with sugar or honey to make a syrup intended to soothe the throat. The preparation requires particular know-how; it is recommended to consult a professional or a proven recipe before attempting it. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
