Acute cardiotoxicity following 'poppy seed tea' consumption

Anaesthesia Reports, 2021
SummaryInsect damage to, and sub‐optimal harvesting practices of the Papaver somniferum poppy are associated with contamination of its seeds with opium alkaloids. Consumption of poppy seeds has been linked to opium‐like overdose symptoms, such as reduced consciousness and respiratory depression.

Poppy Seeds: Implications of Consumption

Medicine, Science and the Law, 1992
Three white poppy seed samples of Papaver somniferum L were found to contain total morphine (free and bound) in the range 58.4 to 62.2μg/g seeds and total codeine (free and bound) in the range 28.4 to 54.1μg/g seeds. Soaking seeds in water was found to remove 45.6 per cent of the free morphine and 48.4 per cent of the free codeine.

Lipolytic activity of poppy seed

Food / Nahrung, 1980
AbstractCrude lipase emulsion from poppy seed hydrolyses its endogenous substrate at an optimum pH of 4.9 and optimum temperature of 22‐25°C. The lipase emulsion is stable up to 50°C. The enzyme is activated by low concentration of calcium ions; at higher concentrations a partial activity drop occurs. The addition of sodium chloride decrease the lipase

Investigation of Turkish Poppy Seeds and Seed Oils

Chemistry of Natural Compounds, 2004
The oil yields, fatty acid compositions, and total protein contents of three varieties of Turkish poppy were investigated. Solvent extraction of yellow seed gave the highest oil yield (49.2%), while white seed (36.8%) and blue seed (33.6) showed considerably lower yields.

Opiate concentrations following the ingestion of poppy seed products – evidence for `the poppy seed defence'

Forensic Science International, 1998
The universally accepted 300 ng/ml cut-off limit for opiate assays stated to be mandatory for all drug screening laboratories by the Substance Abuse and Mental Health Services Administration, has been questioned recently due to positive results being obtained following the ingestion of poppy seed containing food products.

Unusual presentations for pharmacotherapy—poppy seed dependence*

Drug and Alcohol Review, 2006
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 ...

Mexican prickly poppy seed oil

Oil & Soap, 1943
Oil from the Mexican prickly poppy (Argemone mexicana) seed was found to contain the following percentages of acids: Myristic, 0.3; palmitic, 11.1; stearic, 1.8; lignoceric, 0.1; hexadecenoic, 0.8; oleic, 21.3; and linoleic, 58.6. Ricinoleic and linoleic acids, which had been reported by other investigators (2, 3) as constituents of this oil, were not ...

The poppy seed defense: a novel solution

Drug Testing and Analysis, 2013
A major toxicological challenge is distinguishing whether morphine in urine, in the absence of 6‐monoacetylmorphine (6‐MAM), originates from ‘street’ heroin use or poppy seed ingestion. Manufacturing byproducts from the synthesis of illicit heroin include those that originate from the reaction of acetic anhydride with the alkaloid impurity, thebaine ...

[Cadmium in blue poppy seeds and poppy seed-containing products].

Zeitschrift fur Lebensmittel-Untersuchung und -Forschung, 1986
Blue poppy seeds, semi finished products and finished baked goods with poppy seeds, were analyzed for cadmium by atomic-absorption spectrometry. The average content was 0.739 mg/kg (median 0.654 mg/kg) for poppy seeds, 0.317 mg/kg (median 0.366 mg/kg) for semi finished products and 0.107 mg/kg (median 0.088 mg/kg) for baked goods. Poppy seeds therefore
