Scoulerine, also known as discretamine and aequaline, is an alkaloid found in the Opium poppy,^[1] Croton flavens,^[2] and certain plants in the Erythrina genus.^[3] Studies show that scoulerine is an antagonist at the α₂-adrenoceptor, α_1D-adrenoceptor and 5-HT receptor.^[4]^[5] It has also been found to be a GABA_A receptor agonist.^[2]^[6]
