Eschscholzia californica, Papaveraceae (family).

Mechanism of Action


  • Constituents: California poppy yielded alkaloids californidine, escholtzine, N-methyllaurotetanine, caryachine, O-methylcaryachine, and the pavine alkaloid, 6S,12S-neocaryachine-7-O-methyl ether N-metho salt in one study.1
  • Neurological: In an in vitro study, 70% ethanol extract of California poppy was able to bind to 5-HT(1A) and 5-HT(7) receptors.1 The activity on the 5-HT(1A) receptor was at least partly due to the presence of the aporphine alkaloid 3.


  • Insufficient available evidence.
