Papaverine occurs naturally in opium. Papaverine was discovered in 1848 by Georg Merck (1825–1873). [ 2 ] Merck was a student of the German chemists Justus von Liebig and August Hofmann , and he was the son of Emanuel Merck (1794–1855), founder of the Merck corporation, a major German chemical and pharmaceutical company.
Papaver somniferum, commonly known as the opium poppy [2] or breadseed poppy, [3] is a species of flowering plant in the family Papaveraceae. It is the species of plant from which both opium and poppy seeds are derived and is also a valuable ornamental plant grown in gardens.
Juglets resembling poppy seed pods have been discovered with trace amounts of opium and the flower appeared in jewelry and on art pieces in Ancient Egypt, dated 1550–1292 BC. [ 10 ] [ 11 ] The eradication of poppy cultivation came about in the early 1900s through international conferences due to safety concerns associated with the production ...
Poppy seeds come from the opium poppy (or breadseed poppy), a flowering plant likely indigenous to lower Mesopotamia (Southwest Asia). These kidney-shaped, speck-sized dried seeds have no narcotic ...
The Papaveraceae family includes many plants that produce alkaloids, including opium poppy (Papaver somniferum). Opium is derived from the latex of the opium poppy seed pods and has been used for centuries due to its psychoactive properties. The main alkaloids found in opium, such as morphine, and codeine have huge impact on pharmaceuticals and ...
Opium (also known as poppy tears, or Lachryma papaveris) is the dried latex obtained from the seed capsules of the opium poppy Papaver somniferum. [4] Approximately 12 percent of opium is made up of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade.
The calf muscles are your “second heart,” squeezing veins in the lower legs to help return deoxygenated blood from the feet back up towards the chest, the Cleveland Clinic notes.
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
