In the 19th century poppy seed oil was used as cooking oil, lamp oil, and varnish, and was used to make paints and soaps. Today, all of these uses continue, and poppyseed oil has additional culinary and pharmaceutical uses.Particularly notable are its uses as a carrier for oil paints and as a pharmaceutical grade carrier for medicinal iodine and drugs.
Poppyseed oil was sometimes added to olive and almond oils (see Adulterant). In industrialized countries its most important culinary use these days is as a salad or dipping oil.

Cancer therapies
Poppyseed oil had long been used as a carrier for embolizing agents to treat tumors. In the 1980s, in order to better understand the action of these agents, poppyseed oil was replaced with lipiodol, to use its properties as a contrast agent. It soon became apparent that the lipiodol was selectively taken up by tumors. Whether this is true also of poppyseed oil is unknown.
Iodized poppy-seed oil has an especially high rate of uptake into the cells of hepatocellular carcinoma (HCC). This property was soon recognized as an opportunity to deliver to HCC a variety of highly toxic chemotherapy and radiotherapy agents, and formed the basis of several therapies for HCC not treatable by surgery alone. Injected emulsions of epirubicin in lipiodol popular, but greater stability needed.Lipiodol is under investigation as an adjuvant and carrier for use in chemotherapy to treat hepatocellular carcinoma (HCC). It increases the uptake and hence the cytotoxicity of doxorubicin in HCC cells (and also in hepatoblastoma cells). As a carrier, it is under investigation in conjunction with a lipophilic compound of platinum, and in conjunction with a complex derivative of neocarzinostatin. It also is being investigated as a radiation therapy against hepatocellular carcinoma, by being loaded with an isotope of iodine, iodine-131.
Similarly, lipiodol has been used with the chemotherapy agent epirubicin, but with less success than with doxorubicin. Epirubicin is less lipophilic than doxorubicin. However, a "water/oil/water" microemulsion, in which epirubicin was dissolved in droplets of water, and the droplets were suspended in lipiodol, did significantly increase uptake of epirubicin by HCC cells.
Lipiodol is often used in transarterial embolization (TAE), a treatment for HCC, with and without an additional chemotherapy agent. A systematic review of cohort and randomized studies found that TAE improves survival, but found no evidence of additional benefit for using either chemotherapy agents or lipiodol in TAE.

Poppy seeds are notable for being especially high in tocopherols other than vitamin E (alpha-tocopherol). Poppyseed oil from one source has been reported to contain 30.9 mg gamma-tocopherol per 100 g. It also contains alpha and gamma tocotrienols, but not others. Compared to other vegetable oils, poppyseed oil has a moderate amount of phytosterols: higher than soybean oil and peanut oil, lower than safflower oil, sesame oil, wheat germ oil, corn oil, and rice bran oil.Sterols in poppyseed oil consist almost entirely of campesterol, stigmasterol, sitosterol and delta 5-avenasterol.Poppyseed oil is high in linoleic acid. Although not generally higher than safflower oil, it can be as high as 74.5%. Other triglycerides present in notable quantities are oleic acid and palmitic acid.
It is less likely than some other oils to become rancid. It is more stable than safflower oil and linseed oil.
Poppyseed oil is a carrier oil, having little or no odor and a pleasant taste. The primary aroma compound responsible for its flavor is 2-pentylfuran;also present are the volatile compounds 1-pentanol, 1-hexanal, 1-hexanol, and caproic acid.[
Poppyseed oil (also poppy seed oil, poppy oil, and oleum papaveris seminis) is an edible oil from poppy seeds (seeds of Papaver somniferum, the opium poppy). The oil has culinary and pharmaceutical uses, as well as long established uses in the making of paints, varnishes, and soaps.
Poppy seeds yield 45–50% oil. Like poppy seeds, poppyseed oil is highly palatable, high in vitamin E, and has no narcotic properties.
