AbstractTwo cases of patients presenting with opioid dependence who maintained their dependence with poppy tea are described. There appears to have been an increase in this practice in some groups, although dependent use is uncommon. These cases illustrate significant levels of dependence on a licit, and readily available, source of opiates requiring ...

Functional properties of poppy seed meal

Journal of Agricultural and Food Chemistry, 1986
Water and fat absorption capacity, emulsification capacity, and foam capacity and stability of defatted poppy seed meal were determined and compared with those of soybean meal. Poppy seed meal had lower water absorption capacity but higher fat absorption capacity than soybean meal. The emulsification capacity was almost the same as that of soybean meal

Nutritive value of poppy seed protein

Journal of the American Oil Chemists' Society, 1975
AbstractThe chemical and biological properties of poppy seed (Papaver somniferum) were studied to evaluate its possible role as a complement to or replacement for rapeseed in Sweden. A white variety of the seed contained 40% crude oil and 27% protein (N × 6.25), while a blue variety contained 33% oil and 21% protein.
