Morphine is the principal alkaloid of the Opium Poppy and the raw material for producing heroin. Other alkaloids include codeine, thebaine, papaverine and noscapine. These substances can be found in the white latex of the plant. Much has been written about the Opium Poppy and its uses. Be aware it is a powerful plant containing addictive substances so should be used with a certain amount of caution, eating the seeds is probably fine, making a daily infusion of Poppy Pod tea is probably not!
