(Poppy Family)

English name(s) :

Opium Poppy

Maltese name(s) :

Xaħxieħ Vjola, Xaħxieħ

Status for Malta :

Indigenous. Present on the Maltese islands before man

Name Derivation :

Papaver: Latin name for poppy, probably derived from the Latin pappa meaning food or milk, and hence with reference to the milky sap of plants belonging to this genus. (Latin origin ); 2 = Latin name for poppy, also "pappa" is the Latin for food or milk, referring to the milky sap of the plant (Latin).
somniferum subsp. setigerum: 1 = sleep producing / inducing (Latin).

Remarks :

It is believed that our population mostly consists of Papaver somniferum subsp. setigerum (sometimes found as P. setigerum), which is generally a smaller plant with smaller fruit capsules, and short britsles. The other subspecies is Papaver somniferum subsp. somniferum (the cultivated Opium Poppy) and has a large fruit capsule and more glabrous.

Poison:

This poppy has few different characteristics from other poppy species. Like poppies it is an erect plant, with single terminal flower, but the stem is hairless and smooth, except at the upper part (near the flower) where there are sparse white bristles.

The sessile leaves are not much deeply lobed as the other wild poppy species in Malta. Additionally, they are bluish green in colour and more fleshy then its relative species. Their shape is roughly oblong to linear or lanceolate with shallow teeth-like lobes. The margin is dentate and serrate (like a saw). Sometimes. there are few white bristles on the midrib of the leaf. The alternate leaves are not spread out but grows at an acute angle (approx. 30 degrees) to the stem, and looking at the plant sideways, one would see the lower side of the leaf.

The flower's shape and anatomy is similar to other wild poppies, except its colour, which is purple/mauve or lilac. Each of the 4 circularly-shaped petals have a dark purple blob at their base. The petals are very flimsy, and fall off with a slight shake. The stamens, which usually have a black filament and pale yellow anthers, are present in clusters around the central ovary, which is green and glabrous (sometimes shiny). Like other poppies, the flower bud is a peduncle (hanging upside-down) and made up of 2 ovoid bristly sepals. When the flower blooms, the sepals falls off and the flower takes an erect position.

The fruit is a an poricidal dehiscent operculate capsule, which is glabrous, green with a rather yellowish lid, and quite spherical in shape. When it ripens and dries, its tiny, kidney-shaped, dark brown seeds escape from tiny slots in the upper part (lid) of the capsule.

History:

The native land of the plant is believed to be Asia but pictures of poppy have been found on the islands of Crete, dating back to the ancient Greek culture. It is also on the list of medicinal plants in an Egyptian papyrus from 1500 BC.

Papaver Somniferum has been used since Greek times to relieve suffering and euphoria. Records indicate that the opium poppy has been used since the time of Mesopotamia (5000 to 4000 BC). The records refer to the poppy and its use as opiates as medical tablets. "Homer's writings indicate Greek usage of the substance at least by 900 BC: Hippocrates made extensive use of medicinal herbs including opium"   [WWW-19]

It is believed that the Romans probably learned of opium in the Mediterranean. Opium spread to places all over the world. In China opium was reported as a problem during the seventeenth century. Between World War I and H the cultivation of opium grew in Central America in the mountains. Now the major producers and exporters of opium are Turkey and India.   [WWW-19] An excellent abstract regards the history of the Papaver somniferum is this one below taken from the website "Poisonous plants and animals"   [WWW-20]: The poppy is the oldest intoxicating plant in the human history. The plant is an annual, about 1.5 m high. It has white, pink or violet blossoms, and a specific unpleasant smell. Its every part, except for the seeds, contains a white milky resinous liquid, which is, in fact, the raw opium. It is gathered from the plant early in the mourning, kneaded into small flat loaves and then dried.

Turkish warriors always went to battle intoxicated and nothing could stop them. The plant was also popular in India, Taiwan and later in China, where more than 120 million people needed opium in 1878. The desire for tranquility and sweet dreams over and over again led to numerous poisonings. At first, sleepiness appeared, followed by weakness, contracted eye pupils, lower body temperature, and faint breathing. If the dose is high, all this will result in coma.

This lasted until 1805 when a German pharmacist extracted an alkaloid and named it after the Greek god of sleep Morphaeus. It was the first alkaloid which possesses narcotic properties. Morphine is one of the strongest painkillers ever known-a soporific tranquilizer. One who has taken morphine forgets all about hunger, fatigue, grief, and fear. The poison has turned to a medicine but a medicine can also turn to poison. Morphine saves patients from pain but not from the disease, so they need more and more morphine. The symptoms of poisoning are nausea, vomiting and depression. Then come dizziness, dry mouth, breathing disruptions and decreased blood pressure, usually with an unfortunate end. Anyway, millions of people in the whole world still find relief from the pain in this poisonous cure, morphine.

Later, scientists found more than 20 other alkaloids in the opium. The most important ones are codeine and papaverinum. Codeine is a common ingredient of medicines against cough, whereas papaverinum is a popular painkiller of stomachache; it also controls blood vessel spasms.

Morphine played another big, yet evil, part in human history-it is the "father" of heroine (the name is a derivative of hero), the implacable addictive poison of our century created by the German pharmacist H. Dreser working for Bayer. A notoriously bad invention that has lead to many addictions and many deaths!   [WWW-20]

Edible Uses:

Seed: - raw or cooked   [2, 14, 15]. Much used as a flavouring in cakes, bread, fruit salads etc  [183], it imparts a very nice nutty flavour  [KF]. The crushed and sweetened seeds are used as a filling in crepes, strudels, pastries etc  [183]. The seeds are perfectly safe to eat, containing very little if any of the narcotic principles   [10, 65, 238]. The seeds are rather small, but there are large numbers of them contained in capsules 3cm or more in diameter and so they are easy to harvest and utilize   [KF].

Edible young leaves - raw or cooked  [183]. They must be used before the flower buds have formed. One report says that the leaves do not contain any narcotic principles  [179]. Some caution is advised, see notes at top of the page.

Seed Oil: A high quality edible drying oil is obtained from the seed. It has an almond flavour  [238] and makes a good substitute for olive oil  [21, 46, 57, 89, 183].

Medicinal Uses:

The plants extracts, especially opium have the following medicinal properties:

Anodyne used to relieve pain.    [WWW-32]
Antispasmodic used to relieve or prevent spasms (especially of the smooth muscles)    [WWW-32]
Antitussive used to suppress or relieve coughing.    [WWW-32]
Astringent a medication (in the form of an oil or salve etc.) that soothes inflamed or injured skin.    [WWW-32]
Diaphoretic A medicine or agent which promotes perspiration.    [WWW-32]
Emmenagogue used to promote the menstrual discharge.    [WWW-32]
Expectorant used to induce the ejection of mucus, phlegm, and other fluids from the lungs and air passages by coughing or spitting.    [WWW-32]
Homeopathic A term used in medicine when small doses of a drug cure symptoms like those that larger doses would cause    [271]
Hypnotic * used to promote sleep where the effect is intermediate between that of a sedative (tranquilizer) and narcotic.    [271]
Narcotic * causes dulling of consciousness, and hence induces sleep rapidly    [271]
Sedative * used for making drowsy or sooth a patient, but not strong enough to induce sleep    [271]
* The difference between Sedative, Hypnotic and Narcotic can simply lie in the dose of the administered drug.



As the name of the plant suggest, the main use of Opium poppy is the extraction of an important compound called opium. Opium is largely used for manufacture of morphine, codeine, narcotine, laudenine, papaverine, and many other alkaloids. It is also the source of the toxic and extremely habit-forming narcotic heroin or diamorphine, prohibited in some countries.   [WWW-16].

Another source   [WWW-18] states that opium contains a mixture of sixteen or more different alkaloids, with Meconic acid, coloring matters, and various inert substances. The principal constituents are the following alkaloids: Morphine, C17H19NO3 + H2O. codeine, C18H21NO3 + H2O (both official); narcotine, narceine, paramorphine, papaverine, meconidine, pseudomorphine, codamine, laudanine, and oxynarcotine; these are in combination with Meconic and, thebolactic acids. Mineral constituents average about 6 per cent.

The opium poppy contains a wide range of alkaloids and has been a very valuable medicine, especially useful in bringing relief from pain. Its use (especially of the extracted alkaloids opium and morphine which it contains) can become addictive, however, and so it should be treated with extreme caution and only be used under the supervision of a qualified practitioner  [244].

The dried juice (latex) from the unripe green seed vessels is a rich source of the active alkaloids, including morphine  [232, 240]. It is extracted by making shallow incisions in the capsules as soon as the petals have fallen  [4]. Care must be taken that the incisions do not penetrate to the interior of the seed capsules  [4]. The latex exudes from the capsules and dries in contact with the air - it is then scraped off  [4]. This latex is anodyne, antitussive, astringent, diaphoretic, emmenagogue, hypnotic, narcotic and sedative  [4, 7, 13, 176, 192, 218]. As well as its pain-relieving properties, the latex has also been used as an antispasmodic and expectorant in treating certain kinds of coughs, whilst its astringent properties make it useful in the treatment of dysentery etc  [4].

A homeopathic remedy is made from the dried latex  [232]. This is used in the treatment of a variety of complaints, including constipation, fevers and insomnia  [232].
Opium is unexcelled as a hypnotic and sedative, and is frequently administered to relieve pain and calm excitement. For its astringent properties, it is employed in diarrhoea and dysentery, and on account of its expectorant, diaphoretic, sedative and antispasmodic properties, in certain forms of cough, etc.   [WWW-03]

Small doses of opium and morphine are nerve stimulants. The Cutch horsemen share their opium with their jaded steeds, and increased capability of endurance is observed alike in man and beast.   [WWW-03]

Opium and morphine do not produce in animals the general calmative and hypnotic effects which characterize their use in man, but applied locally, they effectually allay pain and spasm. Owing to the greater excitant action in veterinary patients, the administration of opium does not blunt the perception of pain as effectually as it does in human patients.   [WWW-03]

The British Pharmacopeia Tincture of Opium, popularly known as Laudanum, is made with 3 OZ. of Opium and equal parts of distilled water and alcohol, and for immediate effects is usually preferable to solid Opium. Equal parts of Laudanum and Soap Liniment make an excellent anodyne, much used externally.   [WWW-03]

Folk Medicine:

Hartwell (1967-1971) mentions opium as a remedy for such cancerous conditions as cancer of the skin, stomach, tongue, uterus, carcinoma of the breast, polyps of the ear, nose, and vagina; scleroses of the liver, spleen, and uterus; and tumours of the abdomen, bladder, eyes, fauces, liver, spleen, and uvula. The plant, boiled in oil, is said to aid indurations and tumours of the liver. The tincture of the plant is said to help cancerous ulcers. The capsule decoction and an injection of the seed decoction are said to help uterine cancer.   [280]

Egyptians claim to become more cheerful, talkative, and industrious following the eating of opium. When falling asleep, they have visions of "orchards and pleasure gardens embellished with many trees, herbs, and various flowers."
Lebanese use their opium wisely; to quiet excitable people, to relieve toothache, headache, incurable pain, and for boils, coughs, dysentery, and itches.
Algerians tamp opium into tooth cavities. Iranians use the seed for epistaxis; a paste made from Linum, Malva, and Papaver is applied to boils.
In Ayurvedic medicine, the seeds are considered aphrodisiac, constipating, and tonic; the fruit antitussive, binding, cooling, deliriant, excitant, and intoxicant, yet an aphrodisiac if freely indulged; the plant is considered aphrodisiac, astringent, fattening, stimulant, tonic, and good for the complexion;
In Unani medicine, the fruit is suggested as well for anaemia, chest pains, dysentery, fever, but is correctly deemed hypnotic, narcotic, and perhaps harmful to the brain   [282,] .

The plant provides a narcotic that induces sleep; a sleep so heavy that the person becomes insensible. When the Roman soldiers at Golgotha took pity on their prisoner on the cross, they added this poppy juice to the potion of sour wine.
Jewish authorities maintain that the plant and its stupefacience were well known among the Hebrews more than 2,000 years ago.
The Jerushalmi warns against opium eating. Although the seeds contain no narcotic alkaloids, urinalysis following their ingestion may suggest the morphine or heroin addict's urinalysis   [281] .

Other Uses:

The main use of the Papaver Somniferum is extraction of Opium, but it has also other different uses, especially the opium-free seeds.

Seeds are used extensively in baking and sprinkling on rolls and bread. Seeds are a good source of energy. They are also the source of a drying-oil, used for manufacture of paints, varnishes, and soaps, and in foods and salad dressing.   [46, 57, WWW-16]. The seed yields 44 - 50% of an edible drying oil   [61]. Very good for lighting, it burns for longer than most oils  [115].

Other uses include:

  • Oil cake is a good fodder for cattle.
  • Stems used for straw.
  • Lecithin has been extracted from poppy seed meal.
  • Seedlings are eaten as a potherb in Iran.
  • Seeds used for preparation of emulsions (white-seeded varieties preferred); the bluish-black varieties are generally used for baking.
  • As the peony flowered poppy, the opium poppy is widely grown as an ornamental.   [WWW-16]

Cultivation details:

Prefers a rich well-drained sandy loam in a sunny position  [4, 200]. Requires a moist soil  [14] but does not do well on wet clays  [115]. Prefers a sandy loam or a chalky soil  [115]. Plants often self-sow in British gardens.

The opium poppy is a very ornamental plant that is often cultivated in the flower garden  [1]. There are many named varieties, some of which have been developed for their edible uses  [183]. The plant is widely grown, often illegally, in warm temperate and tropical climates for the substances contained in its sap. These are often used medicinally as pain killers, especially in the treatment of terminally ill patients suffering extreme pain, they are also used for their narcotic effects by some people. These substances are highly addictive and lead to a shortening of the life span if used with any frequency. In cool temperate zones the plant does not produce sufficient of the narcotic principles to make their extraction feasible  [4] and cultivation of the plant is perfectly legal in Britain  [KF]. Plants have ripened their seeds as far north as latitude 69°N in Norway  [141].

Members of this genus are rarely if ever troubled by browsing deer or rabbits  [233].

More cultivation notes come from the reference: James A. Duke. 1983. Handbook of Energy Crops. (unpublished.) via brugerforeningen.dk website   [WWW-16]:
Propagated from seed. Seeds germinate best at 15°C and are less sensitive to temperature than most poppy species. Seed sown in shallow furrows, at rate of 4-6 kg/ha. In some areas poppy seed, mixed with sand, is often broadcast over tilled fields in early autumn at rate of about 0.5 kg/ha, as in Asia Minor. Then fields are weeded in the spring when the poppy has grown to about 15 cm tall, and plants are thinned then to stand about 60 cm apart. They flower in April and May and the capsules are ripe in June to July. Optimum yields are obtained when plants are spaced 10 cm between plants and rows 32 cm apart, thus allowing space for mechanical cultivation. Yields of seeds are slightly higher when plants are spaced 30 cm apart than when 40 cm apart. Thinning and spacing do not affect the oil content of the seeds. Fertile soil is essential for good growth and land should be fertilised accordingly.   [WWW-16]

Pests and parasites attacking the plant:

Some of the fungi attacking opium poppy include the following species: Alternaria brassicae var. somniferi, Cladosporium herbarum, Erysiphe polygoni, Fusarium scirpi var. caudatum, Heterosporium echinulatum, Macrosporium papaveris, M. bresdolae, Mucor mucedo, Ophiobolus sativus, Oidium erysiphoides, Peronospora arborescens, P. papaveracea, Rhizoctonia solani, Sclerotinia sclerotiorum, Trichothecium roseum.

Plants are also attacked by the bacteria Bacillus (Erwinia) papaveri, causing bacterial blight, and Xanthomonas papavericola.

The following nematodes have been isolated from the opium poppy: Ditylenchus dipsaci, Longidorus maximus, Meloidogyne sp., Pratylenchus crenatus, P. penetrans, and P. pratensis.

Insect pests include: Aphis papaveris, Ceutorhynchus abbreviatus, C. albovittatus, C. maculaalba, Cynips minor, Dasynevra papaveris, C. callida, Lestodiplosis callida, Mamestra brassicae, Phytomiza albiceps, Sciophila wahlbomiana, and Stenocarus fuliginosus.   [WWW-16] Habituating beetle Finally, it has been frequently observed in Malta that a certain type of beetle resides in the cup-shaped flowers for protection and possibly to feed on. While moving around the ovary it destroys the fragile stamens around the ovary hence hindering the pollination process   [SM]
