Medicinal Actions & Uses

Though the California poppy is a close relation of the opium poppy (Papaver somniferum), it has a significantly different effect on the central nervous system. California poppy is not a narcotic. In fact, rather than disorienting the user, it actually tends to normalize psychological function.

California poppy’s gently antispasmodic, sedative, and analgesic effects make it a valuable herbal medicine for treating physical and psychological problems in children. The herb may prove beneficial in attempts to overcome nervous tension and anxiety, bed-wetting, and difficulty in sleeping.


A French study confirmed the traditional usage of California poppy by showing that extracts were sedative, reduced anxiety levels, and were non-toxic.
