Botanical Name; Osmorhiza longistylis
Family: Apiaceae
Genus: Osmorhiza
Kingdom: Plantae
Order: Apiales

Common Names; Aniseroot, Longstyle sweetroot, American sweet cicely, Licorice root, Wild anise, or Simply sweet cicely

Habitat : Osmorhiza longistylis is native to Eastern N. America – Nova Scotia to Ontario, Alabama, Tennessee, Kansas and Colorado. It grows in rich, often alluvial woods and thickets. Woods, often along the sides of streams in Texas.

Description:
Osmorhiza longistylis is a herbaceous perennial plant is about 1.2 m (4ft) ‘ tall, branching occasionally. The stems are light green to reddish purple, terete, and glabrous (var. longistylis) to hairy (var. villicaulis). The alternate leaves are ternately compound; the lower compound leaves are up to 9″ long and 9″ across, while the upper compound leaves are much smaller in size. Each compound leaf is divided into 3 compound leaflets; the terminal compound leaflet is the largest. Each compound leaflet is further divided into 3 subleaflets; the terminal subleaflet is the largest, sometimes appearing to be divided into 3 even smaller subleaflets. The subleaflets are 1-4″ long, ½-1½” across, and lanceolate to oval-ovate shape in shape; their margins are coarsely serrated-crenate or shallowly cleft. The upper subleaflet surface is yellowish green to green and nearly glabrous (var. longistylis) to moderately covered with appressed hairs (var. villicaulis).

The petioles of compound leaves are light green to reddish purple and up to 6″ in length. The petiolules of leaflets are light green to reddish green and up to 2″ long, while those of subleaflets are nearly sessile to ¼” (6 mm.) long. The foliage of this plant releases a mild anise fragrance when it is rubbed. The upper stems terminate in compound umbels of white flowers about 1½-3″ across. There are about 3-6 umbellets per compound umbel on rays (floral stalks) up to 2″ long. An umbellet has 7-16 flowers that are clustered together on rays (floral stalklets) up to ¼” (6 mm.) long. Each flower (about 3 mm. across) has 5 white petals with incurved tips, 5 white stamens, a pistil with a divided white style (stylopodium), and an insignificant calyx that is light green. At the base of each compound umbel, there are several linear-lanceolate bracts with ciliate margins; they are up to 8 mm. in length. At the base of each umbellet, there are several linear-lanceolate bractlets with ciliate margins; they are also up to 8 mm. in length.

The blooming period occurs during the late spring or early summer, lasting about 2-3 weeks. Afterwards, the flowers are replaced by 2-seeded fruits (schizocarps). While these fruits are still immature, the persistent divided style is 2.0-3.5 mm. in length (it is smaller than this when the flowers are still in bloom). The small seeds are narrowly ellipsoid-oblanceoloid, 5-ribbed, and slightly bristly along their ribs. The root system consists of a cluster of fleshy roots with a strong anise fragrance.

Cultivation:
Succeeds in any deep moisture-retentive soil in sun or dappled shade. Plants are hardy to about -20°c. Well suited to naturalistic plantings in a woodland or wild garden. A sweetly aromatic plant.

Propagation:
Seed – we have no information on this species but suggest sowing the seed in a cold frame as soon as it is ripe if this is possible, otherwise sow it in early spring. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.

Edible Uses :
Edible Parts: Leaves; Root.
Edible Uses: Condiment; Tea.

Root – raw or cooked. Very sweet, aromatic and fleshy. A spicy flavour similar to anise, the roots are chewed, made into a tea or used as a flavouring. Leaves and young shoots – raw. An anise flavour, they are added to salads. The green seeds have an anise flavour and are used as a flavouring in salads, the dry seeds are added to cakes etc.
Medicinal Uses:

Osmorhiza longistylis was used extensively by Native American Indian tribes to treat digestive disorders and as an antiseptic wash for a range of problems. Sweet Cicely is medicinal and edible, the root being the strongest for use in alternative medicine it is antiseptic, aromatic, febrifuge, oxytocic, pectoral, stomachic, carminative, tonic, ophthalmic, and expectorant. Medicinal tea made from the root is a very good digestive aid and is a gentle stimulant for debilitated stomachs. A weak herb tea is used to bath sore eyes. A strong infusion has been used to induce labor in a pregnant woman and to treat fevers, indigestion, flatulence, stomach aches. The crushed root is an effective antiseptic poultice for the treatment of boils and wounds. A medicinal cough syrup can be made of the fresh juice and honey, it is very effective and quite tasty, children take it readily.

Folklore: A decoction of the herb was used as nostril wash to increase dog’s sense of smell. A valuable tonic for girls from 15 to 18 years of age, according to an old herbal. The aromatic scent is said to be an aphrodisiac, used as a love medicine.

In use it should not be confused with species of poison hemlock, water hemlock, or baneberry.

Rosa rugosa

[amazon_link asins=’B00NKKMPWS,0913643076′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ef06e04d-fa58-11e6-b375-a7342f0dd24f’]

Botanical Name : Rosa rugosa
Family: Rosaceae
Genus: Rosa
Species: R. rugosa
Kingdom: Plantae
Order: Rosales

Synonyms : R. ferox.

Common Names: Rugosa rose, Wrinkled Rose, Japanese rose, or Ramanas rose

Habitat: Rosa rugosa is native to E. Asia – N. China, Japan, Korea. Naturalized in several places in Britain. It grows in sandy sea shores.
It has naturalized itself in the sand dunes of the New England seacoast.

Description:
Rosa rugosa is a suckering shrub which develops new plants from the roots and forms dense thickets 1–1.50 m tall with stems densely covered in numerous short, straight prickles 3–10 mm long. The leaves are 8–15 cm long, pinnate with 5–9 leaflets, most often 7, each leaflet 3–4 cm long, with a distinctly corrugated (rugose, hence the species’ name) surface. The flowers are pleasantly scented, dark pink to white (on R. rugosa f. alba (Ware) Rehder), 6–9 cm across, with somewhat wrinkled petals; flowering occurs in spring

CLICK & SEE THE PICTURES

The hips are large, 2–3 cm diameter, and often shorter than their diameter, not elongated; in late summer and early autumn the plants often bear fruit and flowers at the same time. The leaves typically turn bright yellow before falling in autumn.The plant is not frost tender.

Cultivation:
Prefers a light well-drained soil but succeeds in most soils including dry ones. Grows well in heavy clay soils. Prefers a circumneutral soil and a sunny position. Dislikes water-logged soils. Tolerates maritime exposure. Plants are said to withstand temperatures down to -50°c without damage. The foliage is said to resist disease. A very ornamental plant, it suckers freely but these are fairly easily controlled. There are a number of named varieties. ‘Scabrosa’ is said to be larger in all its parts, including the fruit, though it has not proved to be much larger with us. The flowers have a clove-like perfume. Grows well with alliums, parsley, mignonette and lupins. Dislikes boxwood. Garlic planted nearby can help protect the plant from disease and insect predation. Hybridizes freely with other members of this genus. Plants in this genus are notably susceptible to honey fungus.

Propagation :
Seed. Rose seed often takes two years to germinate. This is because it may need a warm spell of weather after a cold spell in order to mature the embryo and reduce the seedcoat[80]. One possible way to reduce this time is to scarify the seed and then place it for 2 – 3 weeks in damp peat at a temperature of 27 – 32°c (by which time the seed should have imbibed). It is then kept at 3°c for the next 4 months by which time it should be starting to germinate[80]. Alternatively, it is possible that seed harvested ‘green’ (when it is fully developed but before it has dried on the plant) and sown immediately will germinate in the late winter. This method has not as yet(1988) been fully tested[80]. Seed sown as soon as it is ripe in a cold frame sometimes germinates in spring though it may take 18 months. Stored seed can be sown as early in the year as possible and stratified for 6 weeks at 5°c. It may take 2 years to germinate. Prick out the seedlings into individual pots when they are large enough to handle. Plant out in the summer if the plants are more than 25cm tall, otherwise grow on in a cold frame for the winter and plant out in late spring. Cuttings of half-ripe wood with a heel, July in a shaded frame. Overwinter the plants in the frame and plant out in late spring. High percentage. Cuttings of mature wood of the current seasons growth. Select pencil thick shoots in early autumn that are about 20 – 25cm long and plant them in a sheltered position outdoors or in a cold frame. The cuttings can take 12 months to establish but a high percentage of them normally succeed. Division of suckers in the dormant season. Plant them out direct into their permanent positions. Layering. Takes 12 months

Edible Uses:
Edible Parts: Flowers; Fruit; Seed; Stem.
Edible Uses: Tea.

Fruit – raw or cooked. They are very sweet and pleasant to eat, though it takes quite a bit of patience to eat any quantity. The fruit is a fairly large size for a rose with a relatively thick layer of flesh. The fruit is about 25mm in diameter. Rich in vitamin C, containing up to 2.75% dry weight. Some care has to be taken when eating this fruit, see the notes above on known hazards. Flowers – raw or cooked. An aromatic flavour, they are also used in jellies and preserves. Remove the bitter white base of the petals before using them. Young shoots – cooked and used as a potherb. Harvested as they come through the ground in spring and are still tender. The seed is a good source of vitamin E, it can be ground into a powder and mixed with flour or added to other foods as a supplement. Be sure to remove the seed hairs. A pleasant tasting fruity-flavoured tea is made from the fruit, it is rich in vitamin C. A tea is also made from the leaves.

Medicinal Uses:

The leaves are used in the treatment of fevers. The flowers act on the spleen and liver, promoting blood circulation. They are used internally in the treatment of poor appetite and digestion, and menstrual complaints arising from constrained liver energy. The root is used in the treatment of coughs. The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers.

In China, the flowers are used to make tea to improve the circulation and to “soothe a restless fetus”. Tea and Jelly made from the rose hips are a very rich source of Vitamin C. The rose hips of this plant have the highest natural concentration of Vitamin C of any other natural source of Vitamin C, including all of the citrus fruits. For the sufferer of scurvy, the Rosa rugosa is a medicinal plant; for the rest of us, it is a nutritional plant.
Other Uses: The plant makes a good low hedge. It is very tolerant of maritime exposure, but is very bare in winter

Known Hazards : There is a layer of hairs around the seeds just beneath the flesh of the fruit. These hairs can cause irritation to the mouth and digestive tract if ingested

Sisymbrium sophia

[amazon_link asins=’B015J5TQ3W,B00DL0EDZO,B00DL0HEKA’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’46663dc0-0cbc-11e7-a188-6752871b9377′]

Botanical Name: Sisymbrium sophia
Family: Brassicaceae
Genus: Sisymbrium
Kingdom: Plantae
Order: Brassicales

Synonyms: Descurainia sophia

Common names: Flixweed, Fluxweed, Ferb-Sophia and Tansy mustard.

Habitat:Sisymbrium sophia is native to Eurasia; it prefers disturbed areas. The non-native Flixweed is an uncommon plant that occurs primarily in NE and west central Illinois; it is rare or absent elsewhere. However, it is probably spreading into other areas of the state. It grows on gravelly or sandy areas along railroads and roadsides, barnyards and pastures, construction sites, and miscellaneous waste areas that are sunny and dry.

Description:
Sisymbrium sophia is a biennial or annual plant is ½–2½’ tall. It branches occasionally, and is more or less erect. The stems are greyish or bluish green and pubescent; sometimes the lower stem is nearly glabrous and light purplish green. During the 1st year, biennial plants consist of a low-growing rosette of basal leaves spanning up to 1′ across. The cauline leaves of annual and 2nd-year biennial plants alternate along the flowering stems, spanning up to 8″ long and 4″ across and becoming progressively smaller higher up on the stems. Both the basal and cauline leaves are double or triple pinnately lobed, greyish or bluish green, and finely pubescent. The basal and lower cauline leaves have long petioles, while the petioles of the upper cauline leaves are shorter.

CLICK & SEE THE PICTURES

The upper stems terminate in racemes of flowers about 2-12″ in length. The flowers bloom near the apex of each raceme, while the siliques (slender seedpods) develop below. Each small flower is about 1/8″ across, consisting 4 pale yellow petals, 4 green sepals, 6 stamens with yellow anthers, and a pistil with a single style. Both the sepals and petals are quite narrow (especially the latter); the petals are about the same length as the sepals or a little shorter. The blooming period occurs from late spring to mid-summer and lasts about 2 months. There is no noticeable floral scent. Each flower is replaced by a silique about 1″ in length. This silique is narrowly cylindrical (about 1 mm. in diameter) and its contains 10-20 tiny seeds in a single row. The slender pedicels of the siliques (or flowers) are about ½” in length. The siliques and their pedicels are spreading-ascending in relation to the stalk of the raceme. Each tiny seed is somewhat flattened and oblongoid; it is some shade of orange-brown. The root system consists of a stout taproot. This plant spreads by reseeding itself; the seeds are small enough to be blown about by the wind.

The nectar and pollen of the flowers attract flower flies and possibly other insects. The caterpillars of the butterflies Pieris rapae (Cabbage White), Pontia protodice (Checkered White), and Anthocharis midea (Falcate Orangetip) feed on the foliage. The relationship of Descurainia spp. (Tansy Mustards) to birds and mammalian herbivores is poorly understood in the eastern states, although in the western states the seedpods are eaten by various species of quail and the foliage is eaten sparingly by Bighorn sheep, elk, and mule deer. However, all parts of the plant have been found to be somewhat toxic to livestock, especially horses and cattle (sheep and goats are more tolerant). The tiny seeds become sticky when wet, and may be carried about in the feathers of birds, fur of animals, or shoes of humans.

Cultivation: Flixweed flourishes in full sun, mesic to dry conditions, and almost any kind of soil. It is taller and more robust on fertile loam, and much smaller in size on dry sterile soil containing gravel or sand. During hot dry weather, the lower leaves may wither away.

Propagation: Seed – sow spring in situ.

Edible Uses: .….Young leaves and shoots – cooked. A bitter flavour. Used as a potherb. Seed – raw or cooked. A pungent taste, it is used as a mustard substitute. The seed can be ground into a powder, mixed with cornmeal and used to make bread, or as a thickening for soups etc. It can also be sprouted and added to salads etc. A nourishing and cooling beverage can be made by mixing the ground up seeds with water to make a thin batter. The seed contains 25.5 – 29.9% protein, 26.9 – 39.7% fat and 3.6 – 3.9% ash on a zero moisture basis.

A poultice of the plant has been used to ease the pain of toothache. The juice of the plant has been used in the treatment of chronic coughs, hoarseness and ulcerated sore throats. A strong decoction of the plant has proved excellent in the treatment of asthm. The flowers and the leaves are antiscorbutic and astringent. The seed is considered to be cardiotonic, demulcent, diuretic, expectorant, febrifuge, laxative, restorative and tonic. It is used in the treatment of asthma, fevers, bronchitis, oedema and dysentery. It is also used in the treatment of worms and calculus complaints. It is decocted with other herbs for treating various ailments. The seeds have formed a special remedy for sciatica. A poultice of the ground up seeds has been used on burns and sores.

Other Uses:….A semi-drying oil is obtained from the seed. Yields are not given. The leaves have been stored with corn to prevent it from going bad.

Coptis trifolia

[amazon_link asins=’2894230710′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’82bb4df1-733a-11e7-8deb-715355a5d785′][amazon_link asins=’B000JLB5Q8′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’3ff0ea7c-733a-11e7-a431-9d2d43ba1adf’]

Botanical Name: Coptis trifolia
Family: Ranunculaceae
Genus: Coptis
Species: C. trifolia
Kingdom: Plantae
Order: Ranunculales

Synonyms: Helleborus triflius or trilobus. Helleborus pumilus. Coptis. Anemone grcenlandica. Coptide. Mouthroot. Vegetable Gold. Chrusa borealis.

Common Names: Coptis groenlandica, Cankerroot , the threeleaf goldthread or savoyane

Habitat:Coptis trifolia is native to Northern America and Asia. Greenland and Iceland.

Description:
Coptis trifolia is a small, perennial, evergreen herb, 4″ – 6″ tall. Leaves are dark, evergreen; divided like those of wild strawberries. The plant has many stems, wiry, branched, and frequently matted. Rhizome is long, slender creeping; bright golden yellow. Flowers are ½” wide, white, bloom in early summer. They form endomycorrhizal associations..CLICK & SEE THE PICTURES.

Parts Used: The dried rhizome, with roots, stems, and leaves.

Constituents: Its bitterness is imparted to both water and alcohol, but more readily to the latter. As there is neither tannic nor gallic acid, the activity is due to berberia or berberine, which is associated with another alkaloid called Coptine or Coptina, resembling hydrastia. It also contains albumen, fixed oil, colouring matter, lignin, extractive, and sugar. Authorities differ as to the presence of resin.

Medicinal Uses:
The roots and rhizomes of cankerroot chewed raw or boiled, have been used to treat canker sores, fever blisters, and other mouth irritations and to treat indigestion and sore throats. A medicinal brew from the roots has been used as an eyewash. The effectiveness of all these uses is due to the presence of the alkaloid berberine, a mild sedative, in the plant. A decoction of equal parts of cankerroot and goldenseal has acquired the reputation of eliminating the craving for alcoholic beverages

It may be used as other pure bitters. In New England it is valued as a local application in thrush, for children.

It is stated to be good for dyspepsia, and combined with other drugs is regarded as helpful in combating the drink habit.

Zea Mays

Post author By Mukul
Post date June 28, 2015
No Comments on Zea Mays

Botanical Name: Zea Mays
Family: Poaceae
Subfamily: Panicoideae
Tribe: Andropogoneae
Genus: Zea
Species: Z. mays
Subspecies: Z. mays subsp. mays
Kingdom: Plantae
Order: Poales

Synonym: Maize.

Common Name: Corn

Habitat: Zea Mays or maize is native to South America; also cultivated in other parts of America, in the West Indian Islands, Australia, Africa, India, etc., and now in France and many other countries in the world.

Description:
Zea Mays is a monoecious plant. Male flowers in terminal racemes; spikelets, two-flowered glumes nearly equal, herbaceous, terminating in two sharp points; females, axillary in the sheaths of the leaves. The spikes or ears proceed from the stalls at various distances from the ground, and are closely enveloped in several thin leaves, forming a sheath called the husk; the ears consist of a cylindrical substance, a pith called the cob; on this the seeds are ranged in eight rows, each row having thirty or more seeds. From the eyes or germs of the seeds proceed individual filaments of a silky appearance and bright green colour; these hang from the point of the husk and are called ‘the silk.’ The use of these filaments or stigmata is to receive the farina which drops from the flowers, and without which the flowers would produce no seed. As soon as this has been effected, the tops and ‘the silk’ dry up. The maize grains are of varying colour – usually yellow, but often ranging to black.

CLICK & SEE THE PICTURES

A coarse annual, culms 60-80 cm high, straight, internodes cylindrical in the upper part, alternately grooved on the lower part with a bud in the groove. The stem is filled with pith. Leaf-blades broad. Has separate staminate (male) and pistillate (female) inflorescences. The staminate inflorescence is a tassel borne at the apex, the pistillate flowers occur as spikes (cobs) rising from axils of the lower leaves. The ovary develops a long style or silk which extends from the cob and receives the pollen from the tassel.

Cultivation :
Requires a warm position a well drained soil and ample moisture in the growing season[16, 33]. Prefers a pH in the range 5.5 to 6.8[200]. Requires a rich soil if it is to do well[201]. Corn is widely cultivated for its edible seed, especially in tropical and warm temperate zones of the world[200], there are many named varieties. Unfortunately, the plant is not frost tolerant and so needs to be started off under glass in Britain if a reasonable crop is to be grown. There are five main types:- Sweetcorn is of fairly recent development. It has very sweet, soft-skinned grains that can be eaten raw or cooked before they are fully ripe. Cultivars have been developed that can produce a worthwhile crop even in the more northerly latitudes of Britain if a suitable warm sunny sheltered site is chosen K. Popcorn is a primitive form with hard-skinned grains. When roasted, these grains ‘explode’ to form the popular snack ‘popcorn’. Waxy corn is used mainly in the Far East. It has a tapioca-like starch. Flint corn, which shrinks on drying, can have white, yellow, purple, red or blue-black grains. It is not so sweet and also takes longer to mature so is a problematic crop in Britain. There are many other uses for this plant as detailed below. Dent corn has mostly white to yellow grains. This and Flint corn are widely grown for oils, cornflour, cereals and silage crops. Corn grows well with early potatoes, legumes, dill, cucurbits and sunflowers, it dislikes growing with tomatoes.
Propagation:
Seed – sow April in individual pots in a greenhouse. Grow on quickly and plant out after the last expected frosts. A direct outdoor sowing, especially of some of the less sweet varieties, can be tried in May.

Edible Uses:
Edible Parts: Oil; Oil; Pollen; Seed; Stem.
Edible Uses: Coffee; Oil; Oil.

Seed – raw or cooked. Corn is one of the most commonly grown foods in the world. The seed can be eaten raw or cooked before it is fully ripe and there are varieties especially developed for this purpose (the sweet corns) that have very sweet seeds and are delicious. The mature seed can be dried and used whole or ground into a flour. It has a very mild flavour and is used especially as a thickening agent in foods such as custards. The starch is often extracted from the grain and used in making confectionery, noodles etc. The dried seed of certain varieties can be heated in an oven when they burst to make ‘Popcorn’. The seed can also be sprouted and used in making uncooked breads and cereals. A nutritional analysis is available. The fresh succulent ‘silks’ (the flowering parts of the cob) can also be eaten. An edible oil is obtained from the seed, it is an all-purpose culinary oil that is frequently used as a food in salads and for cooking purposes. The pollen is used as an ingredient of soups. Rich in protein, it is harvested by tapping the flowering heads over a flat surface such as a bowl. Harvesting the pollen will actually help to improve fertilisation of the seeds. The roasted seed is a coffee substitute. The pith of the stem is chewed like sugar cane and is sometimes made into a syrup

Part Used in Medicines: The Seeds.

Constituents: Starch, sugar, fat, salts, water, yellow oil, maizenic acid, azotized matter, gluten, dextrine, glucose, cellulose, silica, phosphates of lime and magnesia, soluble salts of potassa and soda.

Medicinal Uses:

A decoction of the leaves and roots is used in the treatment of strangury, dysuria and gravel. The corn silks are cholagogue, demulcent, diuretic, lithontripic, mildly stimulant and vasodilator. They also act to reduce blood sugar levels and so are used in the treatment of diabetes mellitus as well as cystitis, gonorrhoea, gout etc. The silks are harvested before pollination occurs and are best used when fresh because they tend to lose their diuretic effect when stored and also become purgative. A decoction of the cob is used in the treatment of nose bleeds and menorrhagia. The seed is diuretic and a mild stimulant. It is a good emollient poultice for ulcers, swellings and rheumatic pains, and is widely used in the treatment of cancer, tumours and warts. It contains the cell-proliferant and wound-healing substance allantoin, which is widely used in herbal medicine (especially from the herb comfrey, Symphytum officinale) to speed the healing process. The plant is said to have anticancer properties and is experimentally hypoglycaemic and hypotensive.

Other Uses:
Adhesive; Fuel; Oil; Oil; Packing; Paper.

A glue is made from the starch in the seed. This starch is also used in cosmetics and the manufacture of glucose. A semi-drying oil is obtained from the seed. It has many industrial uses, in the manufacture of linoleum, paints, varnishes, soaps etc. The corn spathes are used in the production of paper, straw hats and small articles such as little baskets. A fibre obtained from the stems and seed husks is used for making paper. They are harvested in late summer after the seed has been harvested, they are cut into usable pieces and soaked in clear water for 24 hours. They are then cooked for 2 hours in soda ash and then beaten in a ball mill for 1½ hours in a ball mill. The fibres make a light greenish cream paper. Be careful not to overcook the fibre otherwise it will produce a sticky pulp that is very hard to form into paper. The dried cobs are used as a fuel. The pith of the stems is used as a packing material
In addition to use as a human food, the seed head and whole plant are used forage and silage, an important source of feed for livestock. Corn has become an increasingly important biofuel, both in the form of corn oil (used as bio-diesel) and ethanol (an alcohol fermented and distilled from the processed kernels), which is blended with petroleum-based gasoline in various proportions for use as fuel.

With Although grown in temperate and tropical countries worldwide, the U.S. alone produces more than one third of the global total of dried corn (316.2 metric tons), with China, Brazil, Mexico, and Argentina also producing significant amounts. Corn production increased by 42% worldwide over the past decade, associated with the increased demand and prices for corn as biofuel.
