Californidine is an alkaloid with the molecular formula C20H20NO4+.

It has been isolated from extracts of the California poppy (Eschscholzia californica),[1][2] from which it gets its name, and from other plants of the genus Eschscholzia.

[3][4] Because of the sedative, anxiolytic, and analgesic effects, the herb California Poppy (Amapola de California, Eschscholzia californica, Pavot d'Amérique, Pavot d'Or, Pavot de Californie, Poppy California, Yellow Poppy) is currently sold in pharmacies in many countries.
