Mandragora autumnalis Bertol. [1] | |
Mandragora autumnalis, known as mandrake [2] or autumn mandrake, [3] is recognized by some sources as a separate species from Mandragora officinarum , although with different circumscriptions. Others regard it as merely part of this very variable species. Plants given the name Mandragora autumnalis consist of a rosette of leaves up to 60 cm (2 ft) across, close to the ground, with a central group of usually purplish flowers followed by yellow or orange berries. The large tap-roots as well as the leaves contain alkaloids and are toxic. They have traditional uses as herbal medicines.
The boundary between the two species Mandragora autumnalis and Mandragora officinarum varies among authors, with some regarding them as the same species (see § Taxonomy below). Whatever distinction is used, plants of M. autumnalis are herbaceous perennials, with a large upright tap-root, often branched and sometimes shaped somewhat like a person. There is little or no stem, the leaves being borne in a basal rosette up to 60 cm (2 ft) across. The flowers are clustered at the centre of the rosette, each with five sepals, five petals and five stamens. Both the sepals and petals are fused at the base forming two five-lobed bell-shaped cups. The ovary has two chambers (locules) and a long style. The fruit is a fleshy berry with many seeds. [4] [5]
For those authors who regard Mandragora autumnalis as the main species found around the Mediterranean, it has flowers varying in colour but typically violet or purple, 30–40 mm (1–2 in) long, and berries that are yellow or orange and egg-shaped, while the much less widespread Mandragora officinarum has somewhat smaller flowers, greenish-white in colour, and berries that are yellow and globe-shaped. [5] [2] Those who regard M. officinarum as the main species found around the Mediterranean, with M. autumnalis being found only in the Levant, use the size of the seeds as one of the distinguishing factors, those of M. autumnalis being more than twice the size of those of M. officinarum. [6] In Palestine, where the native taxon is M. autumnalis in both approaches, it flowers between December and February, i.e. not only in the autumn as the specific epithet might suggest. [7]
In 1753, in the first edition of Species Plantarum , Carl Linnaeus described a single species, Mandragora officinarum , for plants found around the Mediterranean. [8] [9] Jackson and Berry (1979) [10] and Ungricht et al. (1998) [4] have documented the subsequent confusion over the number of Mediterranean species of Mandragora and their scientific names. Antonio Bertoloni used flowering time to name two species: Mandragora autumnalis, the autumn-flowering mandrake, in 1820, [1] and Mandragora vernalis, the spring-flowering mandrake, in 1824. [11] M. vernalis is considered to be the same as Linnaeus's M. officinarum. [4] Three interpretations of Mandragora autumnalis are in use:
In one treatment, Mandragora autumnalis is the main species of Mandragora found all around the Mediterranean, in Tunisia, Algeria, Morocco, southern Portugal, southern Spain, southern Italy, Greece, Cyprus, Turkey, Syria, Lebanon, Palestine, and Jordan, being absent in northern Italy and a region on the coast of former Yugoslavia, where it is replaced by M. officinarum. [5] [2] [4] In another treatment, Mandragora autumnalis is native only to the Levant (from Syria south to Palestine), the species found elsewhere around the Mediterranean being M. officinarum. [6]
All species of Mandragora contain highly biologically active alkaloids, tropane alkaloids in particular. Jackson and Berry were unable to find any differences in the composition of these chemicals between Mandragora autumnalis and Mandragora officinarum (using the broader definition of M. autumnalis). Alkaloids present included hyoscyamine, hyoscine, cuscohygrine, apoatropine, 3-alpha-tigloyloxytropane, 3-alpha,6-beta-ditigloyloxytropane and belladonnine. Non-alkaloid constituents included sitosterol and beta-methylesculetin (scopoletin). [10]
The alkaloids make the plant, particularly the root and leaves, poisonous. Clinical reports of the effects of consumption of Mandragora autumnalis include severe symptoms similar to those of atropine poisoning, including blurred vision, dilation of the pupils (mydriasis), dryness of the mouth, difficulty in urinating, dizziness, headache, vomiting, blushing and a rapid heart rate (tachycardia). Hyperactivity and hallucinations also occurred in the majority of patients. [12] [13]
Mandragora species have a long use in traditional medicine, an extract being used for its real or supposed aphrodisiac, hypnotic, emetic, purgative, sedative and pain-killing effects. Tropane alkaloids are known to be effective as analgesics and anaesthetics, and can be used to increase circulation and dilate pupils, among other effects. [4] Continued use of M. autumnalis in folk medicine was reported in Sicily in 2014. [14]
Datura is a genus of nine species of highly poisonous, vespertine-flowering plants belonging to the nightshade family (Solanaceae). They are commonly known as thornapples or jimsonweeds, but are also known as devil's trumpets or mad apple. Other English common names include moonflower, devil's weed, and hell's bells. All species of Datura are extremely poisonous and psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, anticholinergic toxidrome, psychosis, and death if taken internally.
Datura stramonium, known by the common names thornapple, jimsonweed, or devil's trumpet, is a poisonous flowering plant in the Daturae tribe of the nightshade family Solanaceae. Its likely origin was in Central America, and it has been introduced in many world regions. It is an aggressive invasive weed in temperate climates and tropical climates across the world. D. stramonium has frequently been employed in traditional medicine to treat a variety of ailments. It has also been used as a hallucinogen, taken entheogenically to cause intense, sacred or occult visions. It is unlikely ever to become a major drug of abuse owing to effects upon both mind and body frequently perceived as being highly unpleasant, giving rise to a state of profound and long-lasting disorientation or delirium with a potentially fatal outcome. It contains tropane alkaloids which are responsible for the psychoactive effects, and may be severely toxic.
Atropa is a genus of flowering plants in the nightshade family, Solanaceae: tall, calcicole, herbaceous perennials, bearing large leaves and glossy berries particularly dangerous to children, due to their combination of an attractive, cherry-like appearance with a high toxicity. Atropa species favour temperate climates and alkaline soils, often growing in light shade in woodland environments associated with limestone hills and mountains. Their seeds can remain viable in the soil for long periods, germinating when the soil of sites in which plants once grew is disturbed by human activity or by natural causes, e.g. the windthrow of trees. The best-known member of the genus Atropa is deadly nightshade – the poisonous plant par excellence in the minds of many. The pharmacologically active ingredients of Atropa species include atropine, scopolamine, and hyoscyamine, all tropane alkaloids having anticholinergic, deliriant, antispasmodic and mydriatic properties. The genus is named for Άτροπος (Atropos) – lit. 'she who may not be turned (aside)' – one of the Three Fates and cutter of the thread of life / bringer of death – in reference to the extreme toxicity of A.belladonna and its fellow species – of which four others are currently accepted.
Atropa bella-donna, commonly known as deadly nightshade or belladonna, is a toxic perennial herbaceous plant in the nightshade family Solanaceae, which also includes tomatoes, potatoes and aubergine (eggplant). It is native to Europe and Western Asia, including Turkey, its distribution extending from England in the west to western Ukraine and the Iranian province of Gilan in the east. It is also naturalised or introduced in some parts of Canada, North Africa and the United States.
Hyoscyamine is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, the sorcerers' tree, and Atropa belladonna. It is the levorotary isomer of atropine and thus sometimes known as levo-atropine.
A besom is a broom, a household implement used for sweeping. The term is mostly reserved for a traditional broom constructed from a bundle of twigs tied to a stout pole. The twigs used could be broom, heather or similar. The song "Buy Broom Buzzems" from Northern England refers to both types of twig. From the phrase broom besom the more common broom comes. In Scotland and Bulgaria, besoms are still occasionally to be found at the edge of forests where they are stacked for use in early response to an outbreak of fire.
Mandrake is a poisonous herbaceous plant in the genus Mandragora, often connected with magical rituals.
Deliriants are a subclass of hallucinogen. The term was coined in the early 1980s to distinguish these drugs from psychedelics such as LSD and dissociatives such as ketamine, due to their primary effect of causing delirium, as opposed to the more lucid and less disturbed states produced by other types of hallucinogens. The term generally refers to anticholinergic drugs, which are substances that inhibit the function of the neurotransmitter acetylcholine.
Mandragora officinarum is the type species of the plant genus Mandragora in the nightshade family Solanaceae. It is often known as mandrake, although this name is also used for other plants. As of 2015, sources differed significantly in the species they use for Mandragora plants native to the Mediterranean region. The main species found around the Mediterranean is called Mandragora autumnalis, the autumn mandrake. In a broader circumscription, all the plants native to the regions around the Mediterranean Sea are placed in M. officinarum, which thus includes M. autumnalis. The names autumn mandrake and Mediterranean mandrake are then used. Whatever the circumscription, Mandragora officinarum is a perennial herbaceous plant with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers followed by yellow or orange berries.
Mandragora may refer to:
Brugmansia versicolor is a species of plant in the family Solanaceae, commonly known as “angel’s trumpets”. They are endemic to Ecuador. Since March 2014, they have been listed as Extinct in the Wild by the IUCN.
Tropane alkaloids are a class of bicyclic [3.2.1] alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Certain tropane alkaloids such as cocaine and scopolamine are notorious for their psychoactive effects, related usage and cultural associations. Particular tropane alkaloids such as these have pharmacological properties and can act as anticholinergics or stimulants.
Mandragora is a plant genus belonging to the nightshade family (Solanaceae). Members of the genus are known as mandrakes. Between three and five species are placed in the genus. The one or two species found around the Mediterranean constitute the mandrake of ancient writers such as Dioscorides. Two or three further species are found eastwards into China. All are perennial herbaceous plants, with large tap roots and leaves in the form of a rosette. Individual flowers are bell-shaped, whitish through to violet, and followed by yellow or orange berries.
A mandrake is the root of a plant, historically derived either from plants of the genus Mandragora found in the Mediterranean region, or from other species, such as Bryonia alba or the American mandrake which have similar properties. The plants from which the root is obtained are also called "mandrakes". Mediterranean mandrakes are perennial herbaceous plants with ovate leaves arranged in a rosette, a thick upright root, often branched, and bell-shaped flowers that produce yellow or orange berries. They have been placed in different species by different authors. They are highly variable perennial herbaceous plants with long thick roots and almost no stem. The leaves are borne in a basal rosette, and are variable in size and shape, with a maximum length of 45 cm (18 in). They are usually either elliptical in shape or wider towards the end (obovate), with varying degrees of hairiness.
Mandragora turcomanica, the Turkmenian mandrake, is a perennial herbaceous plant in the family Solanaceae, native to the Köpet Dag mountains in Turkmenistan and one location in neighbouring Iran. It differs from the mandrakes found around the Mediterranean chiefly by being larger.
Mandragora caulescens, the Himalayan mandrake, is a perennial herbaceous plant in the family Solanaceae, native to the Himalayas and mountainous regions of Myanmar and south-west China. One of the differences from the other species of Mandragora is that it has a stem, whereas they are stemless. Like all species of Mandragora, it contains tropane alkaloids, making it toxic. It is used in traditional Chinese medicine.
The Solanaceae, or the nightshades, is a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell, and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Apoatropine (atropatropine) is a member of class of tropane alkaloids. Chemically, it is an ester formed from tropine and atropic acid. Apoatropine can be found in plants of family Solanaceae. It is a bitter crystalline alkaloid. Examples of related tropane alkaloids include atropine, hyoscyamine, and hyoscine. Though apoatropine is found in various plants, it can also be prepared by the dehydration of atropine using nitric acid. Apoatropine is used as a pigment.
Atropa baetica, commonly known as the Andalusian belladonna, is one of Europe's rarest wildflowers. A close relative of the infamous deadly nightshade, its specific name derives from that of the Roman province of Hispania Baetica, while its common name refers to the Spanish region of Andalucía – both designating the area in the south of Spain where it is most frequently encountered. It is an attractive perennial plant with a herbaceous habit, bearing infundibuliform, yellow or greenish flowers and shiny, black berries. Like the other three species of Atropa, it is an extremely poisonous plant, containing a variety of tropane alkaloids with anticholinergic, deliriant, antispasmodic and mydriatic properties. Although most populations of the plant are to be found in Spain, it is not wholly confined to the Iberian Peninsula of Europe, occurring also in certain localities in Morocco and Algeria in the Atlas Mountains of North Africa. The Rif and the Baetic System, which face each other across the Alboran Sea, together constitute one of the finest of the Mediterranean biodiversity hotspots – rich in endemic species, of which Atropa baetica is a notable example..
