Multnomah County, Oregon
Multnomah County is one of 36 counties in the U. S. state of Oregon. As of the 2010 United States Census, the county's population was 735,334, its county seat, Portland, is the state's largest city. Multnomah County is part of the Portland-Vancouver-Hillsboro, OR-WA Metropolitan Statistical Area, though smallest in area, it is the state's most populous county. Multnomah County was created on December 22, 1854, formed out of two other Oregon counties – the eastern part of Washington County and the northern part of Clackamas County, its creation was a result of a petition earlier that year by businessmen in Portland complaining of the inconvenient location of the Washington County seat in Hillsboro and of the share of Portland tax revenues leaving the city to support Washington County farmers. County commissioners met for the first time on January 17, 1855; the county is named after the Chinookan word for the "lower river", Matlnomaq, máɬnumax̣ being interpretive English spellings of the same word.
In Chinook Jargon, Ne-matlnomaq, means the "place of matlnomaq" or the Ne-matlnomag, "the lower river", from the Oregon City Falls toward the Columbia river. Alternatively, Chinookan máɬnumax̣ ‘those toward water’; the explorer William Clark wrote in his Journal: "I entered this river...called Multnomah...from a nation who reside on Wappato Island, a little below the enterence". Although Clark refers to the Willamette River as Multnomah, he may not have understood the meaning. Put, Multnomahis the shortened form of nematlnomaq/nímaɬnumax̣". In 1924, the county's three commissioners were indicted and recalled by voters "in response to'gross irregularities' in the award of contracts for construction of the Burnside and Ross Island bridges". Vanport, built north of Portland in 1943 to house workers for Kaiser Shipyards, was destroyed by a flood five years later. In 1968, the Oregon Legislative Assembly referred a bill, Ballot Measure 5, to voters that would amend the state constitution to allow for consolidated city-county governments when the population is over 300,000.
The 1968 voters' pamphlet noted that Multnomah County would be the only county in Oregon affected by the measure and voters approved the referendum in the 1968 general election. Since the approval of Measure 5 in 1968, an initiative to merge the county with Portland has been considered and placed on the county ballot several times; the merger would have formed a consolidated city-county government like that of San Francisco, California. None of these proposals has been approved. In the 2000 presidential election, Multnomah played a decisive role in determining the winner of the state's electoral votes. Al Gore carried the county by more than 104,000 votes, enough to offset the nearly 100,000-vote advantage that George W. Bush had earned among Oregon's 35 other counties; the Democratic tilt was repeated in 2004, when John Kerry won by 181,000 votes, in 2008 when Barack Obama won by 204,000 votes. In February 2001, the Multnomah County Board of Commissioners unanimously accepted the recommendation of the Library Advisory Board and authorized the library to enter into a lawsuit to stop the Children's Internet Protection Act.
The US Supreme Court decided in 2003 that the law was constitutional in US v. ALA. However, the library chose to turn down $104,000 per year of federal funding under CIPA to be able to continue to offer unfiltered Internet access. Faced with decreasing government revenues due to a recession in the local economy, voters approved a three-year local income tax on May 20, 2003 to prevent further cuts in schools, police protection, social services. Multnomah County was one of the few local governments in Oregon to approve such a tax increase. On March 2, 2004, Multnomah County Chair Diane Linn announced the county would begin granting licenses for same-sex marriages, pursuant to a legal opinion issued by its attorney deeming such marriages lawful under Oregon law, her announcement was supported by three other commissioners, but criticized by Lonnie Roberts, who represents the eastern part of Multnomah county and was left out of the decision. Within a few days, several groups joined to file a lawsuit to halt the county's action.
But after that and the three commissioners developed a public feud, with the latter becoming known as the "mean girls". The county government has faced significant budget issues, including not being able to open the Wapato Corrections Facility since it was built in 2003. According to the United States Census Bureau, the county has a total area of 466 square miles, of which 431 square miles is land and 34 square miles is water, it is the smallest county in Oregon by area. It is located along the south side of the Columbia River; the county includes a number of extinct volcanoes in the Boring Lava Field. The Oregon side of the Columbia River Gorge forms the eastern portion of the county's northern border. I-5 I-84 I-205 I-405 US 26 US 30 US 30 Byp.

Portland is the largest and most populous city in the U. S. state of Oregon and the seat of Multnomah County. It is a major port in the Willamette Valley region of the Pacific Northwest, at the confluence of the Willamette and Columbia rivers; as of 2017, Portland had an estimated population of 647,805, making it the 26th-largest city in the United States, the second-most populous in the Pacific Northwest. 2.4 million people live in the Portland metropolitan statistical area, making it the 25th most populous MSA in the United States. Its Combined Statistical Area ranks 18th-largest with a population of around 3.2 million. 60% of Oregon's population resides within the Portland metropolitan area. Named after Portland, the Oregon settlement began to be populated in the 1830s near the end of the Oregon Trail, its water access provided convenient transportation of goods, the timber industry was a major force in the city's early economy. At the turn of the 20th century, the city had a reputation as one of the most dangerous port cities in the world, a hub for organized crime and racketeering.
After the city's economy experienced an industrial boom during World War II, its hard-edged reputation began to dissipate. Beginning in the 1960s, Portland became noted for its growing progressive political values, earning it a reputation as a bastion of counterculture; the city operates with a commission-based government guided by a mayor and four commissioners as well as Metro, the only directly elected metropolitan planning organization in the United States. The city government is notable for its land-use investment in public transportation. Portland is recognized as one of the world's most environmentally conscious cities because of its high walkability, large community of bicyclists, farm-to-table dining, expansive network of public transportation options, over 10,000 acres of public parks, its climate is marked by cool, rainy winters. This climate is ideal for growing roses, Portland has been called the "City of Roses" for over a century. During the prehistoric period, the land that would become Portland was flooded after the collapse of glacial dams from Lake Missoula, in what would become Montana.
These massive floods occurred during the last ice age and filled the Willamette Valley with 300 to 400 feet of water. Before American pioneers began arriving in the 1800s, the land was inhabited for many centuries by two bands of indigenous Chinook people—the Multnomah and the Clackamas; the Chinook people occupying the land were first documented in 1805 by Meriwether Lewis and William Clark. Before its European settlement, the Portland Basin of the lower Columbia River and Willamette River valleys had been one of the most densely populated regions on the Pacific Coast. Large numbers of pioneer settlers began arriving in the Willamette Valley in the 1830s via the Oregon Trail, though life was centered in nearby Oregon City. In the early 1840s a new settlement emerged ten miles from the mouth of the Willamette River halfway between Oregon City and Fort Vancouver; this community was referred to as "Stumptown" and "The Clearing" because of the many trees cut down to allow for its growth. In 1843 William Overton saw potential in the new settlement but lacked the funds to file an official land claim.
For 25 cents, Overton agreed to share half of the 640-acre site with Asa Lovejoy of Boston. In 1845 Overton sold his remaining half of the claim to Francis W. Pettygrove of Maine. Both Pettygrove and Lovejoy wished to rename "The Clearing" after their respective hometowns; this controversy was settled with a coin toss that Pettygrove won in a series of two out of three tosses, thereby providing Portland with its namesake. The coin used for this decision, now known as the Portland Penny, is on display in the headquarters of the Oregon Historical Society. At the time of its incorporation on February 8, 1851, Portland had over 800 inhabitants, a steam sawmill, a log cabin hotel, a newspaper, the Weekly Oregonian. A major fire swept through downtown in August 1873, destroying twenty blocks on the west side of the Willamette along Yamhill and Morrison Streets, causing $1.3 million in damage. By 1879, the population had grown to 17,500 and by 1890 it had grown to 46,385. In 1888, the city built the first steel bridge built on the West Coast.
Portland's access to the Pacific Ocean via the Willamette and Columbia rivers, as well as its easy access to the agricultural Tualatin Valley via the "Great Plank Road", provided the pioneer city with an advantage over other nearby ports, it grew quickly. Portland remained the major port in the Pacific Northwest for much of the 19th century, until the 1890s, when Seattle's deepwater harbor was connected to the rest of the mainland by rail, affording an inland route without the treacherous navigation of the Columbia River; the city had its own Japantown, for one, the lumber industry became a prominent economic presence, due to the area's large population of Douglas Firs, Western Hemlocks, Red Cedars, Big Leaf Maple trees. Portland developed a reputation early in its history as a gritty port town; some historians have described the city's early establishment as being a "scion of New England. In 1889, The Oregonian called Portland "the most filthy city in the Northern States", due to the unsanitary sewers and gutters, and, at the turn of the 20th century, it was considered one of the most dangerous port cities in the world.
The city housed a large number of saloons
The Portland Tribune is a free newspaper published twice weekly, each Tuesday and Thursday, in Portland, United States. The Tribune is part of the Pamplin Media Group, which publishes a number of community newspapers in the Portland metropolitan area, owns and operates the talk radio station KPAM, several other radio stations throughout the Pacific Northwest; the Tribune has twice been chosen as the nation's best non-daily paper. Launched in 2001, the paper was published twice-weekly until 2008, when it was reduced to weekly, returned to twice-weekly publication in 2014. Portland businessman Robert B. Pamplin, Jr. announced his intention to found the paper in the summer of 2000. The first issue of the twice-weekly paper was published February 9, 2001, joining The Oregonian, the city's only daily general interest newspaper, the alternative weeklies Willamette Week and The Portland Mercury. At the time, it was a rare example of the expansion of print news, in a time when many cities were seeing newspapers merge or go out of business.
But its launch preceded a significant national downturn in advertising sales, which posed difficulties for a startup newspaper. Eleven months after its launch, the Tribune cut back on home deliveries; the newspaper was losing money faster than anticipated after its first year. By late 2006, its newsroom staff had been reduced to 27. On May 5, 2008, the paper announced it would switch effective to a once-a-week print format, with a Thursday print edition accompanied by daily updates to its website. In July 2009, "difficult economic conditions" led to the layoff of two reporters and the resignation of its managing editor, resulting in a newsroom staff of 14. In March 2014, the Portland Tribune resumed twice-weekly publication of its print edition, with reinstatement of a Tuesday edition, while continuing to publish a Thursday edition; the paper deals exclusively with issues local to Portland and the U. S. state of Oregon. The paper is known for its extensive coverage of local high school and professional sports teams, with concentration on the NBA, Pac-10, Big Sky Conference and West Coast Conference.
A business section was added to the print edition in 2014, along with other coverage expansion, including health and fitness content and more regional coverage. The Tribune sponsors the annual Portland Regional Spelling Bee for middle school students; the champion participates in the Scripps National Spelling Bee in Washington, D. C.

A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e. having specialized tissues that conduct water and nutrients and in having life cycles in which the sporophyte is the dominant phase. Like other vascular plants, ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns, sometimes referred to as true ferns, they produce coiled fiddleheads that expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate and eusporangiate ferns, the latter itself comprising ferns other than those denominated true ferns, including horsetails or scouring rushes, whisk ferns, marattioid ferns, ophioglossoid ferns. Ferns first appear in the fossil record about 360 million years ago in the late Devonian period, but many of the current families and species did not appear until 145 million years ago in the early Cretaceous, after flowering plants came to dominate many environments.
The fern Osmunda claytoniana is a paramount example of evolutionary stasis. Ferns are not of major economic importance, but some are used for food, medicine, as biofertilizer, as ornamental plants and for remediating contaminated soil, they have been the subject of research for their ability to remove some chemical pollutants from the atmosphere. Some fern species, such as bracken and water fern are significant weeds world wide; some fern genera, such as Azolla can fix nitrogen and make a significant input to the nitrogen nutrition of rice paddies. They play certain roles in mythology and art. Like the sporophytes of seed plants, those of ferns consist of stems and roots. Stems: Fern stems are referred to as rhizomes though they grow underground only in some of the species. Epiphytic species and many of the terrestrial ones have above-ground creeping stolons, many groups have above-ground erect semi-woody trunks; these can reach up to 20 meters tall in a few species. Leaf: The green, photosynthetic part of the plant is technically a megaphyll and in ferns, it is referred to as a frond.
New leaves expand by the unrolling of a tight spiral called a crozier or fiddlehead fern. This uncurling of the leaf is termed circinate vernation. Leaves are divided into a sporophyll. A trophophyll frond is a vegetative leaf analogous to the typical green leaves of seed plants that does not produce spores, instead only producing sugars by photosynthesis. A sporophyll frond is a fertile leaf that produces spores borne in sporangia that are clustered to form sori. In most ferns, fertile leaves are morphologically similar to the sterile ones, they photosynthesize in the same way. In some groups, the fertile leaves are much narrower than the sterile leaves, may have no green tissue at all; the anatomy of fern leaves can either be simple or divided. In tree ferns, the main stalk that connects the leaf to the stem has multiple leaflets; the leafy structures that grow from the stipe are known as pinnae and are again divided into smaller pinnules. Roots: The underground non-photosynthetic structures that take up water and nutrients from soil.
They are always fibrous and structurally are similar to the roots of seed plants. Like all other vascular plants, the diploid sporophyte is the dominant phase or generation in the life cycle; the gametophytes of ferns, are different from those of seed plants. They are free-living and resemble liverworts, whereas those of seed plants develop within the spore wall and are dependent on the parent sporophyte for their nutrition. A fern gametophyte consists of: Prothallus: A green, photosynthetic structure, one cell thick heart or kidney shaped, 3–10 mm long and 2–8 mm broad; the prothallus produces gametes by means of: Antheridia: Small spherical structures that produce flagellate sperm. Archegonia: A flask-shaped structure that produces a single egg at the bottom, reached by the sperm by swimming down the neck. Rhizoids: root-like structures that consist of single elongated cells, that absorb water and mineral salts over the whole structure. Rhizoids anchor the prothallus to the soil. Ferns first appear in the fossil record in the early Carboniferous period.
By the Triassic, the first evidence of ferns related to several modern families appeared. The great fern radiation occurred in the late Cretaceous, when many modern families of ferns first appeared. Ferns were traditionally classified in the class Filices, in a Division of the Plant Kingdom named Pteridophyta or Filicophyta. Pteridophyta is no longer recognised as a valid taxon; the ferns are referred to as Polypodiophyta or, when treated as a subdivision of Tracheophyta, although this name sometimes only refers to leptosporangiate ferns. Traditionally, all of the spore producing vascular plants were informally denominated the pteridophytes, rendering the term synonymous with ferns and fern allies; this can be confusing because members of the division Pteridophyta were denominated pteridophytes. Traditionally, three discrete groups have be
Oregon is a state in the Pacific Northwest region on the West Coast of the United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho; the parallel 42 ° north delineates the southern boundary with Nevada. Oregon is one of only four states of the continental United States to have a coastline on the Pacific Ocean. Oregon was inhabited by many indigenous tribes before Western traders and settlers arrived. An autonomous government was formed in the Oregon Country in 1843 before the Oregon Territory was created in 1848. Oregon became the 33rd state on February 14, 1859. Today, at 98,000 square miles, Oregon is the ninth largest and, with a population of 4 million, 27th most populous U. S. state. The capital, Salem, is the second most populous city in Oregon, with 169,798 residents. Portland, with 647,805, ranks as the 26th among U. S. cities. The Portland metropolitan area, which includes the city of Vancouver, Washington, to the north, ranks the 25th largest metro area in the nation, with a population of 2,453,168.
Oregon is one of the most geographically diverse states in the U. S. marked by volcanoes, abundant bodies of water, dense evergreen and mixed forests, as well as high deserts and semi-arid shrublands. At 11,249 feet, Mount Hood, a stratovolcano, is the state's highest point. Oregon's only national park, Crater Lake National Park, comprises the caldera surrounding Crater Lake, the deepest lake in the United States; the state is home to the single largest organism in the world, Armillaria ostoyae, a fungus that runs beneath 2,200 acres of the Malheur National Forest. Because of its diverse landscapes and waterways, Oregon's economy is powered by various forms of agriculture and hydroelectric power. Oregon is the top timber producer of the contiguous United States, the timber industry dominated the state's economy in the 20th century. Technology is another one of Oregon's major economic forces, beginning in the 1970s with the establishment of the Silicon Forest and the expansion of Tektronix and Intel.
Sportswear company Nike, Inc. headquartered in Beaverton, is the state's largest public corporation with an annual revenue of $30.6 billion. The earliest evidence of the name Oregon has Spanish origins; the term "orejón" comes from the historical chronicle Relación de la Alta y Baja California written by the new Spaniard Rodrigo Montezuma and made reference to the Columbia River when the Spanish explorers penetrated into the actual North American territory that became part of the Viceroyalty of New Spain. This chronicle is the first topographical and linguistic source with respect to the place name Oregon. There are two other sources with Spanish origins, such as the name Oregano, which grows in the southern part of the region, it is most probable that the American territory was named by the Spaniards, as there are some populations in Spain such as "Arroyo del Oregón" considering that the individualization in Spanish language "El Orejón" with the mutation of the letter "g" instead of "j". Another early use of the name, spelled Ouragon, was in a 1765 petition by Major Robert Rogers to the Kingdom of Great Britain.
The term referred to the then-mythical River of the West. By 1778, the spelling had shifted to Oregon. In his 1765 petition, Rogers wrote: The rout...is from the Great Lakes towards the Head of the Mississippi, from thence to the River called by the Indians Ouragon... One theory is that the name comes from the French word ouragan, applied to the River of the West based on Native American tales of powerful Chinook winds on the lower Columbia River, or from firsthand French experience with the Chinook winds of the Great Plains. At the time, the River of the West was thought to rise in western Minnesota and flow west through the Great Plains. Joaquin Miller explained in Sunset magazine, in 1904, how Oregon's name was derived: The name, Oregon, is rounded down phonetically, from Ouve água—Oragua, Or-a-gon, Oregon—given by the same Portuguese navigator that named the Farallones after his first officer, it in a large way, means cascades:'Hear the waters.' You should steam up the Columbia and hear and feel the waters falling out of the clouds of Mount Hood to understand the full meaning of the name Ouve a água, Oregon.
Another account, endorsed as the "most plausible explanation" in the book Oregon Geographic Names, was advanced by George R. Stewart in a 1944 article in American Speech. According to Stewart, the name came from an engraver's error in a French map published in the early 18th century, on which the Ouisiconsink River was spelled "Ouaricon-sint", broken on two lines with the -sint below, so there appeared to be a river flowing to the west named "Ouaricon". According to the Oregon Tourism Commission, present-day Oregonians pronounce the state's name as "or-uh-gun, never or-ee-gone". After being drafted by the Detroit Lions in 2002, former Oregon Ducks quarterback Joey Harrington distributed "Orygun" stickers to members of the media as a reminder of how to pronounce the name of his home state; the stickers are sold by the University of Oregon Bookstore. Oregon is 295 miles north to south at longest distance, 395 miles east to west. With an area of 98,381 square miles, Oregon is larger than the United Kingdom.
It is the ninth largest state in the United States. Oregon's highest point is the summit of Mount Hood, at 11,249 feet, its lowest point is the sea level of the Pacific Ocean along the Oregon Coas
The Oregonian is a daily newspaper based in Portland, United States, owned by Advance Publications. It is the oldest continuously published newspaper on the U. S. west coast, founded as a weekly by Thomas J. Dryer on December 4, 1850, published daily since 1861, it is the largest newspaper in Oregon and the second largest in the Pacific Northwest by circulation. It is one of the few newspapers with a statewide focus in the United States; the Sunday edition is published under the title The Sunday Oregonian. The regular edition was published under the title The Morning Oregonian from 1861 until 1937; the Oregonian received the 2001 Pulitzer Prize for Public Service, the only gold medal annually awarded by the organization. The paper's staff or individual writers have received seven other Pulitzer Prizes, most the award for Editorial Writing in 2014; the Oregonian is home-delivered throughout Multnomah, Washington and Yamhill counties in Oregon and Clark County, Washington four days a week. Although some independent dealers do deliver the newspaper outside that area, in 2006 it ceased to be available in far eastern Oregon and the southern Oregon Coast and, starting in December 2008, "increasing newsprint and distribution costs" caused the paper to stop delivery to all areas south of Albany.
One year prior to the incorporation of the tiny town of Portland, Oregon, in 1851, prospective leaders of the new community determined to establish a local newspaper—an institution, seen as a prerequisite for urban growth. Chief among these pioneer community organizers seeking establishment of a Portland press were Col. W. W. Chapman and prominent local businessman Henry W. Corbett. In the fall of 1850 Chapman and Corbett traveled to San Francisco, at the time far and away the largest city on the West Coast of the United States, in search of an editor interested in and capable of producing a weekly newspaper in Portland. There the pair met Thomas J. Dryer, a transplanted New Yorker, an energetic writer with both printing equipment and previous experience in the production of a small circulation community newspaper in his native Ulster County, New York. Dryer's press was transported to Portland and it was there on December 4, 1850 that the first issue of The Weekly Oregonian found its readers.
Each weekly issue consisted of four pages, printed six columns wide. Little attention was paid to current news events, with the bulk of the paper's content devoted to political themes and biographical commentary; the paper took a staunch political line supportive of the Whig Party—an orientation which soon brought it into conflict with The Statesman, a Democratic paper launched at Oregon City not long after The Weekly Oregonian's debut. A loud and bitter rivalry between the competing news organs ensued. Henry Pittock became the owner in 1861 as compensation for unpaid wages, he began publishing the paper daily, except Sundays. Pittock's goal was to focus more on news than the bully pulpit established by Dryer, he ordered a new press in December 1860 and arranged for the news to be sent by telegraph to Redding, California by stagecoach to Jacksonville, by pony express to Portland. From 1866 to 1872 Harvey W. Scott was the editor. Henry W. Corbett bought the paper from a cash-poor Pittock in October 1872 and placed William Lair Hill as editor.
Scott, fired by Corbett for supporting Ben Holladay's candidates, became editor of Holladay's rival Bulletin newspaper. The paper went bankrupt around 1874. Corbett sold The Oregonian back to Pittock in 1877, marking a return of Scott to the paper's editorial helm. A part-owner of the paper, Scott would remain as editor-in-chief until shortly before his death in 1910. One of the journalists who began his career on The Oregonian during this time period was James J. Montague who took over and wrote the column "Slings & Arrows" until he was hired away by William Randolph Hearst in 1902. In 1881, the first Sunday Oregonian was published; the paper became known as the voice of business-oriented Republicans, as evidenced by consistent endorsement of Republican candidates for president in every federal election before 1992. The paper's offices and presses were housed in a two-story building at the intersection of First Street and Morrison Street, but in 1892 the paper moved into a new nine-story building at 6th and Alder streets.
The new building was, the same as its predecessor, called the Oregonian Building. It included a clock tower at one corner, the building's overall height of 194 to 196 feet made it the tallest structure in Portland, a distinction it retained until the completion of the Yeon Building in 1911, it contained about 100,000 square feet of floor space, including the basement but not the tower. The newspaper did not move again until 1948; the 1892 building was demolished in 1950. Following the death of Harvey Scott in 1910, the paper's editor-in-chief was Edgar B. Piper, managing editor. Piper remained editor until his death in 1928. In 1922, The Morning Oregonian launched Oregon's first commercial radio station. Five years KGW affiliated with NBC; the newspaper purchased a second station, KEX, in 1933, from NBC subsidiary Northwest Broadcasting Co. In 1944, KEX was sold to Inc.. The Oregonian launched KGW-FM, the Northwest's first FM station, in 1946, known today as KKRZ. KGW and KGW-FM were sold to King Broadcasting Co in 1953.
In 1937, The Morning Oregonian shortened its name to The Oregonian. Two years associate editor Ronald G. Callvert rec
In general use, herbs are plants with savory or aromatic properties that are used for flavoring and garnishing food, medicinal purposes, or for fragrances. Culinary use distinguishes herbs from spices. Herbs refers to the leafy green or flowering parts of a plant, while spices are dried and produced from other parts of the plant, including seeds, bark and fruits. Herbs have a variety of uses including culinary, in some cases, spiritual. General usage of the term "herb" differs between medicinal herbs; the word "herb" is pronounced in Commonwealth English, but is common among North American English speakers and those from other regions where h-dropping occurs. In botany, the word "herb" is used as a synonym for "herbaceous plant". In botany, the term herb refers to a herbaceous plant, defined as a small, seed-bearing plant without a woody stem in which all aerial parts die back to the ground at the end of each growing season; the term refers to perennials, although herbaceous plants can be annuals, or biennials.
This term is in contrast to trees which possess a woody stem. Shrubs and trees are defined in terms of size, where shrubs are less than 10 meters tall, trees may grow over 10 meters; the word herbaceous is derived from Latin herbāceus meaning "grassy", from herba "grass, herb". Another sense of the term herb can refer to a much larger range of plants, with culinary, therapeutic or other uses. For example, some of the most described herbs such as Sage and Lavender would be excluded from the botanical definition of a herb as they do not die down each year, they possess woody stems. In the wider sense, herbs may be herbaceous perennials but trees, shrubs, lianas, mosses, algae and fungi. Herbalism can utilize not just stems and leaves but fruit, roots and gums; therefore one suggested definition of a herb is a plant, of use to humans, although this definition is problematic since it could cover a great many plants that are not described as herbs. Ancient Greek philosopher Theophrastus divided the plant world into trees and herbs.
Herbs came to be considered in namely pot herbs, sweet herbs and salad herbs. During the seventeenth century as selective breeding changed the plants size and flavor away from the wild plant, pot herbs began to be referred to as vegetables as they were no longer considered only suitable for the pot. Culinary herbs are distinguished from vegetables in that, like spices, they are used in small amounts and provide flavor rather than substance to food. Herbs can be perennials such as thyme, sage or lavender, biennials such as parsley, or annuals like basil. Perennial herbs can be shrubs such as rosemary, Rosmarinus officinalis, or trees such as bay laurel, Laurus nobilis – this contrasts with botanical herbs, which by definition cannot be woody plants; some plants are used as both herbs and spices, such as dill weed and dill seed or coriander leaves and seeds. There are some herbs, such as those in the mint family, that are used for both culinary and medicinal purposes. Emperor Charlemagne compiled a list of 74 different herbs.
The connection between herbs and health is important in the European Middle Ages--The Forme of Cury promotes extensive use of herbs, including in salads, claims in its preface "the assent and advisement of the masters of physic and philosophy in the King's Court". Some herbs can be infused in boiling water to make herbal teas; the dried leaves, flowers or seeds are used, or fresh herbs are used. Herbal teas tend to made from aromatic herbs, may not contain tannins or caffeine, are not mixed with milk. Common examples include mint tea. Herbal teas are used as a source of relaxation or can be associated with rituals. Herbs were used in prehistoric medicine; as far back as 5000 BCE, evidence that Sumerians used herbs in medicine was inscribed on cuneiform. In 162 CE, the physician Galen was known for concocting complicated herbal remedies that contained up to 100 ingredients; some plants contain phytochemicals. There may be some effects when consumed in the small levels that typify culinary "spicing", some herbs are toxic in larger quantities.
For instance, some types of herbal extract, such as the extract of St. John's-wort or of kava can be used for medical purposes to relieve depression and stress. However, large amounts of these herbs may lead to toxic overload that may involve complications, some of a serious nature, should be used with caution. Complications can arise when being taken with some prescription medicines. Herbs have long been used as the basis of traditional Chinese herbal medicine, with usage dating as far back as the first century CE and far before. In India, the Ayurveda medicinal system is based on herbs. Medicinal use of herbs in Western cultures has its roots in the Hippocratic elemental healing system, based on a quaternary elemental healing metaphor. Famous herbalist of the Western tradition include Avicenna, Paracelsus and the botanically inclined Eclectic physicians of 19th
