Botanical Name : Betula alleghaniensis
Family : Betulaceae
Genus : Betula
Subgenus: Betulenta
Synonyms: Betula lutea – Michx.
Common Name : Yellow Birch
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Fagales
Species: B. alleghaniensis

Habitat :Native to eastern North America, from Nova Scotia, New Brunswick, southern Québec and Ontario, and the sud- east corner of Manitoba in Canada, west to Minnesota, and south in the Appalachian Mountains to northern Georgia. North-eastern N. America – Newfoundland to Virginia and Tennessee. Usually found in moist well-drained soils in rich woodlands on lower slopes, it is also found in cool marshlands in the south of its range.

Description:
It is a medium-sized deciduous tree reaching 20 m tall (exceptionally to 30 m) with a trunk up to 80 cm diameter. The bark is smooth, yellow-bronze, flaking in fine horizontal strips, and often with small black marks and scars. The twigs, when scraped, have a slight scent of oil of wintergreen, though not as strongly so as the related Sweet Birch. The leaves are alternate, ovate, 6-12 cm long and 4-9 cm broad, with a finely serrated margin. The flowers are wind-pollinated catkins 3-6 cm long, the male catkins pendulous, the female catkins erect. The fruit, mature in fall, is composed of numerous tiny winged seeds packed between the catkin bracts.

Leaves of Betula alleghaniensis are simple, alternate and doubly-toothed. The sap has the smell and taste of wintergreen. Mature trees of Betula alleghaniensis are unmistakeable by their papery, yellowish, often shiny bark, but seedlings and saplings can be more difficult to distinguish from other Betula species. As is the case with some other birches it tends to develop conspicuous spur branches (though not necessarily on sprouts and the fastest growing twigs).

Betula alleghaniensis is the provincial tree of Québec, where it is commonly called merisier, a name which in France is used for the wild cherry.

The name “yellow birch” reflects the color of the tree’s bark.

It is hardy to zone 4. It is in flower in April, and the seeds ripen in October. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Cultivation :
Succeeds in a well-drained loamy soil in a sheltered position. Grows well in heavy clay soils. Dislikes wet soils[200]. Shade tolerant[200]. A slow-growing tree, it is relatively long-lived for a birch, with specimens 200 years old recorded. Plants often grow taller than the 12 metres mentioned above[229]. The trees are highly susceptible to forest fires, even when wet the bark is highly inflammable. The bruised foliage has a strong smell of wintergreen[200]. Hybridizes freely with other members of this genus. Trees are notably susceptible to honey fungus.

Propagation:
Seed – best sown as soon as it is ripe in a light position in a cold frame. Only just cover the seed and place the pot in a sunny position. Spring sown seed should be surface sown in a sunny position in a cold frame. If the germination is poor, raising the temperature by covering the seed with glass can help. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. If you have sufficient seed, it can be sown in an outdoor seedbed, either as soon as it is ripe or in the early spring – do not cover the spring sown seed. Grow the plants on in the seedbed for 2 years before planting them out into their permanent positions in the winter.

Edible Uses:
Edible Parts: Inner bark; Sap.

Edible Uses: Condiment; Sweetener; Tea.

Inner bark – cooked or dried and ground into a powder and used with cereals in making bread. Inner bark is generally only seen as a famine food, used when other forms of starch are not available or are in short supply. Sap – raw or cooked. A sweet flavour. The sap is harvested in early spring, before the leaves unfurl, by tapping the trunk. It flows abundantly, but the sugar content is much lower than maple sap. A pleasant drink, it can also be concentrated into a syrup or fermented into a beer. An old English recipe for the beer is as follows:- “To every Gallon of Birch-water put a quart of Honey, well stirr’d together; then boil it almost an hour with a few Cloves, and a little Limon-peel, keeping it well scumm’d. When it is sufficiently boil’d, and become cold, add to it three or four Spoonfuls of good Ale to make it work…and when the Test begins to settle, bottle it up . . . it is gentle, and very harmless in operation within the body, and exceedingly sharpens the Appetite, being drunk ante pastum.”. A tea is made from the twigs and leaves. The dried leaves are used according to another report. An excellent flavour. The twigs and leaves have the flavour of wintergreen and can be used as condiments.

Medicinal Actions & Uses:
Cathartic; Emetic.

Yellow birch is little used medicinally, though a decoction of the bark has been used by the native North American Indians as a blood purifier, acting to cleanse the body by its emetic and cathartic properties. The bark is a source of ‘Oil of Wintergreen’. This does have medicinal properties, though it is mainly used as a flavouring in medicines[2.

Other Uses:
Containers; Fuel; Waterproofing; Wood.

The bark is waterproof and has been used by native peoples as the outer skin of canoes, as roofing material on dwellings and to make containers such as buckets, baskets and dishes. Wood – close-grained, very strong, hard, heavy. The wood is too dense to float. An important source of hardwood lumber, it is used for furniture, boxes, tubs of wheels, floors etc. It is also often used as a fuel.

The wood of Betula alleghaniensis is extensively used for flooring, cabinetry and toothpicks. Most wood sold as birch in North America is from this tree. Several species of Lepidoptera use the species as a food plant for their caterpillars. See List of Lepidoptera that feed on birches.

Scented Plants
Leaves: Crushed

Botanical Name:Betula
Family: Betulaceae
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Fagales
Genus: Betula
Common Name:The common name birch is derived from an old Germanic root, birka, with the Proto-Indo-European root *bherag, “white, bright; to shine.” The Proto-Germanic rune berkanan is named after the birch. The botanic name Betula is from the original Latin.Birch is the name of any tree of the genus Betula (Bé-tu-la), in the family Betulaceae, closely related to the beech/oak family, Fagaceae.Bhurjapatra,Betula utilis.

Parts Used:Leaves, bark, sap.
Habitat: Native to Europe from the northern Mediterranean regions to Siberia and to temperate regions of Asia, it is also found in North America. Grows in mostly of northern temperate climates.

Description:The tree is handsomely deciduous, reaching 100 feet in height, with pale gray papery bark, toothed leaves, and catkins in the spring. The birch flourishes in woods, thickets, and in private gardens. The leaves are collected in the wild during the spring.The simple leaves may be toothed or pointed. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (Alnus, other genus in the family) in that the female catkins are not woody and disintegrate at maturity, falling apart to release the seeds, unlike the woody cone-like female alder catkins.

........

The bark of all birches is characteristically marked with long horizontal lenticels, and often separates into thin papery plates, especially upon the Paper Birch. It is practically imperishable, due to the resinous oil which it contains. Its decided color gives the common names Red, White, Black], Silver and Yellow to different species.

The buds form early and are full grown by midsummer, all are lateral, no terminal bud is formed; the branch is prolonged by the upper lateral bud. The wood of all the species is close-grained with satiny texture and capable of taking a fine polish; its fuel value is fair.

The leaves of the different species vary but little. All are alternate, doubly serrate, feather-veined, petiolate, and stipulate. Apparently they often appear in pairs, but these pairs are really borne on spur-like two-leaved lateral branchlets.

Flower and fruit
The flowers are monoecious, opening with or before the leaves and borne on three-flowered clusters in the axils of the scales of drooping or erect aments. Staminate aments are pendulous, clustered or solitary in the axils of the last leaves of the branch of the year or near the ends of the short lateral branchlets of the year. They form in early autumn and remain rigid during the winter. The scales of the staminate aments when mature are broadly ovate, rounded, yellow or orange color below the middle, dark chestnut brown at apex. Each scale bears two bractlets and three sterile flowers, each flower consisting of a sessile, membranaceous, usually two-lobed, calyx. Each calyx bears four short filaments with one-celled anthers or strictly, two filaments divided into two branches, each bearing a half-anther. Anther cells open longitudinally. The pistillate aments (catkins) are erect or pendulous, solitary; terminal on the two-leaved lateral spur-like branchlets of the year. The pistillate scales are oblong-ovate, three-lobed, pale yellow green often tinged with red, becoming brown at maturity. These scales bear two or three fertile flowers, each flower consisting of a naked ovary. The ovary is compressed, two-celled, and crowned with two slender styles; the ovule is solitary.

The ripened pistillate ament is called a strobile and bears tiny winged nuts, packed in the protecting curve of each brown and woody scale. These nuts are pale chestnut brown, compressed, crowned by the persistent stigmas. The seed fills the cavity of the nut. The cotyledons are flat and fleshy. All the species are easily grown from seed.

Ecology
Birches often form even-aged stands on light, well-drained, particularly acidic soils. They are regarded as pioneer species, rapidly colonising open ground especially in secondary successional sequences following a disturbance or fire. Birches are early tree species to establish in primary successions and can become a threat to heathland if the seedlings and saplings are not suppressed by grazing or periodic burning. Birches are generally lowland species, but some species such as Betula nana have a montane distribution. Birch is used as a food plant by the larvae of a large number of Lepidoptera (butterflies and moths) species, see List of Lepidoptera that feed on birches.

Uses:
Birch wood is fine-grained and pale in colour, often with an attractive satin-like sheen. Ripple figuring may occur, increasing the value of the timber for veneer and furniture-making. The highly-decorative Masur (or Karelian) birch, from Betula verrucosa var. carelica has ripple texture combined with attractive dark streaks and lines. Birch wood is suitable for veneer, and birch ply is among the strongest and most dimensionally-stable plywoods, although it is unsuitable for exterior use.

Due to birch pulp’s short-fibre qualities, this hardwood can be used to make printing paper. In India the thin bark coming off in winter was used as writing paper. This has excellent life. The paper is known as bhoorj patra. Bhoorj is the Sanskrit name of tree and patra means paper. This bark also has been used widely in ancient Russia as note paper (beresta) and for decorative purposes and even making footwear — lapti.

Extracts of birch are used for flavoring or leather oil, and in cosmetics such as soap or shampoo. In the past, commercial oil of wintergreen (methyl salicylate) was made from the Sweet Birch (Betula lenta). Birch tar or Russian Oil, extracted from birch bark, is thermoplastic and waterproof; it was used as a glue on, for example, arrows, and also for medicinal purposes.

Silver Birch (Betula pendula) is Finland’s national tree. Occasionally one uses leafy, fragrant twigs of silver birch to gently beat oneself in a sauna. The twigs are called vihta or vasta. This has a relaxing effect on the muscles.

Birch leaves make a diuretic tea and to make extracts for dyes and cosmetics.

Ground birch bark, fermented in sea water, is used for seasoning the woolen, hemp or linen sails and hemp rope of traditional Norwegian boats.

Birch twigs were bound in a bundle, also called birch, to be used for birching, a form of corporal punishment.

Many of the First Nations of North America prized the birch for its bark, which due to its light weight, flexibility, and the ease with which it could be stripped from fallen trees, was often used for the construction of strong, waterproof but lightweight canoes, bowls, and wigwams.

Birch is used as firewood due to its high calorific value per unit weight and unit volume. Birch is prized by the Sami people as it burns well, without popping, even when frozen and freshly hewn. The bark is also used in starting fires. The bark will burn very well, even when wet, because of the oils it contains. With care, the bark can be split into very thin sheets that will ignite from even the smallest of sparks.

Birches also have spiritual importance in several religions, both modern and historical.

Birch ply is made from laminations of birch veneer. It is light but strong and has many other good properties. Birch ply is used to make longboards (skateboard), giving it a strong yet flexy ride. It is also used (often in very thin grades with many laminations) for making model aircraft.

Tonewood
Baltic Birch is among the most sought after wood in the manufacture of speaker cabinets. Birch has a natural resonance that peaks in the high and low frequencies, which are also the hardest for speakers to reproduce. This resonance compensates for the roll-off of low and high frequencies in the speakers, and evens the tone. Birch is known for having “natural EQ.”

Drums are often made from Birch. Prior to the 1970s, Birch was one of the most popular drum woods. Because of the need for greater volume and midrange clarity, drums were made almost entirely from maple until recently, when advancements in live sound reinforcement and drum mics have allowed the use of Birch in high volume situations. Birch drums have a natural boost in the high and low frequencies, which allow the drums to sound fuller.

Birch wood is sometimes used as a tonewood for semi-acoustic and acoustic guitar bodies and occasionally used for solid-body guitar bodies. Birch wood is also a common material used in mallets for keyboard percussion.

Food
In Belarus, Russia, the Baltic States, Finland, Sweden, Denmark and parts of northern China, birch sap is consumed as a refreshing beer, and is believed to have tonic qualities. It is watery and pale green in color, with a slightly sweet flavor, and is bottled commercially. Birch sap may also be made into kvass. The sap of particular birch species may also be rendered into birch syrup, vinegar, birch wine (which most often turns out a sparkling wine, although Grythyttan Vin AB of Sweden also produces a still birch wine), birch beer (a soft drink similar to root beer), and other foods. In contrast to maple syrup, birch syrup is very difficult to produce, making it more expensive than other food syrups. It is also considerably less sweet than maple syrup and the sap for syrup production is not available until a month later than maple’s. The syrup is made mainly in Alaska (from Alaska Birch) and Russia (from several species), and more rarely elsewhere.

Xylitol can also be extracted from birch, a sugar alcohol artificial sweetener, which has shown effectiveness in preventing, and in some cases repairing, tooth decay.

According to the Food Network series Unwrapped, birch is a preferred wood for the manufacture of toothpicks.

Medicinal uses:

Key Actions:
*antiseptic
*astringent
*anti-inflammatory
*diuretic
In northern latitudes birch is considered to be the most important allergenic tree pollen, with an estimated 15-20% of hay fever sufferers sensitive to birch pollen grains.

The chaga mushroom is an adaptogen that grows on white birch trees, extracting the birch constituents and is used as a remedy for cancer.

The bark is high in betulin and betulinic acid, phytochemicals which have potential as pharmaceuticals, and other chemicals which show promise as industrial lubricants.

Birch bark can be soaked until moist in water, and then formed into a cast for a broken arm.

The inner bark of birch can be ingested safely.

A German study indicated that the leaves were useful in treating bacterial and inflammatory diseases of the urinary tract.

Black Birch was used commercially in the past for production of oil of wintergreen before modern industrial synthesis; the tree’s name reflects this scent of the shoots.

The sap flows about a month later than maple sap, and much faster. The trees can be tapped in a similar fashion, but must be gathered about three times more often. Birch sap can be boiled the same as maple sap, but its syrup is stronger (like molasses).

The Sweet Birch‘s leaves serve as food for some lepidopteran caterpillars. See List of Lepidoptera which feed on Birches.

History: The black birch was widely used by American Indians, in bark tea for fevers, stomachaches, lung ailments; twig tea for fever. Essential oil (methyl salicylate) distilled from bark was used for rheumatism, gout, scrofulas, bladder infection, and neuralgia.

Harvest: Twigs, red inner bark, and bark of larger roots year round, but best in late winter and spring. Sap in early spring, 3 to 4 weeks later than Sugar Maple.Harvest during Spring (sap & inner bark); All Year (twigs).

Constituents: Essential oil (methyl salicylate).
Nutrients: Vitamins A, B1, B2, C, and E. Calcium, chlorine, copper, iron, magnesium, phosphorus, potassium, sodium, and silicon.

Note: It has been recorded that during the civil war, the edible bark of Black Birch probably saved the lives of hundreds of confederate soldiers.

Edible Uses: Tea, flour.
Medicinal Properties & Uses: Black Birch has anthelmintic, astringent and diuretic properties.It is Anti-inflammatory, Analgesic, Anthelmintic, Astringent, Diuretic, Diaphoretic, Stimulant. A tea made from the inner bark is used as a mouthwash and in diarrhoea, rheumatism, gout and boils. It purifies the blood also.
Used in the treatment of diarrhea, dysentery and cholera. The natural properties are cleansing to the blood and it is used specifically for rheumatism, dropsy, gout, stones in the kidneys and bladder, and to expel worms.
To alleviate pain or sore muscles, the oil has been applied as a counterirritant. The essential oil was formerly produced in Appalachia. But now, methyl salicylate is produced synthetically, using menthol as the precursor.
The oil of Birch is applied to the skin for eczema and cutaneous diseases; the tea is effective when gargled for canker and mouth sores.
The cambium (the layer directly under the bark) is eaten in the spring, cut into strips like vermicelli. The bark, in the form of an infusion is used as a general stimulant and to promote sweating. As a decoction or syrup, it is used as a tonic for dysentery and is said to be useful in genito-urinary irritation. The flavor of wintergreen and birch bark, in the form of a tea, was popular with Native Americans and European settlers. The juice of the leaves once made a gargle for mouth sores. Throughout the centuries, the sap has been used in making medicinal wine and were made into a diuretic tea. Also an ingredient in skin lotions.

Preparation And Dosages:
Bark – Strong decoction, (1 to 2 ounces, up to 4 times a day).

Bilberry is a name given to several species of low-growing shrubs in the genus Vaccinium (family Ericaceae) that bear tasty fruits. The species most often referred to is Vaccinium myrtillus L., also known as blaeberry, whortleberry, whinberry (or winberry), myrtle blueberry, fraughan, and probably other names regionally. They were called black-hearts in 19th century southern England, according to Thomas Hardy‘s 1878 novel, The Return of the Native, (pg. 311, Oxford World’s Classics edition).
Bilberry fruitThe word bilberry is also sometimes used in the common names of other species of the genus, including Vaccinium uliginosum L. (bog bilberry, bog blueberry, bog whortleberry, bog huckleberry, northern bilberry), Vaccinium caespitosum Michx. (dwarf bilberry), Vaccinium deliciosum Piper (Cascade bilberry), Vaccinium membranaceum (mountain bilberry, black mountain huckleberry, black huckleberry, twin-leaved huckleberry), and Vaccinium ovalifolium (oval-leafed blueberry, oval-leaved bilberry, mountain blueberry, high-bush blueberry).

Bilberries are found in damp, acidic soils throughout the temperate and subarctic regions of the world. They are closely related to North American wild and cultivated blueberries and huckleberries in the genus Vaccinium. The easiest way to distinguish the bilberry is that it produces single or pairs of berries on the bush instead of clusters like the blueberry. Bilberry is used as a food plant by the larvae of some Lepidoptera species – see list of Lepidoptera which feed on Vaccinium.

Bilberries are rarely cultivated but fruits are sometimes collected from wild plants growing on publicly accessible lands, notably in Fennoscandia, Scotland, Ireland and Poland. Notice that in Fennoscandia, it is an everyman’s right to collect bilberries, irrespective of land ownership. In Ireland the fruit is known as fraughan in English, from the Irish fraochÃ¡n, and is traditionally gathered on the last Sunday in July, known as Fraughan Sunday.

Confusion between bilberries and American blueberries:
Since many people refer to “blueberries”, no matter if they mean the bilberry (European blueberry) Vaccinium myrtillus or the American blueberries, there is a lot of confusion about the two closely similar fruits. One can distinguish bilberries from their American counterpart by the following differences:
*bilberries have dark red, strongly fragrant flesh and red juice that turns blue in basic environments: blueberries have white or translucent, mildly fragrant flesh

*bilberries grow on low bushes with solitary fruits, and are found wild in heathland in the Northern Hemisphere; blueberries grow on large bushes with the fruit in bunches
bilberries are wild plants while blueberries are cultivated and widely available commercially

*cultivated blueberries often come from hybrid cultivars, developed about 100 years ago by agricultural specialists, most prominently by Elizabeth Coleman White, to meet growing consumer demand; since they are bigger, the bushes grow taller, and are easier to harvest

*bilberry fruit will stain hands, teeth and tongue deep blue or purple while eating; it was used as a dye for food and clothes: blueberries have flesh of a less intense colour, thus less staining

*when cooked as a dessert, bilberries have a much stronger, more tart flavour and a rougher texture than blueberries

Adding to the confusion is the fact there are also wild American blueberry varieties, sold in stores mainly in the USA and Canada. These are uncommon outside of Northern America. Even more confusion is due to the huckleberry name, which originates from English dialectal names ‘hurtleberry’ and ‘whortleberry’ for the bilberry.

Edible Uses: The fruits can be eaten fresh, but are more usually made into jams, fools, juices or pies. In France they are used as a base for liqueurs and are a popular flavouring for sorbets and other desserts. In Brittany they are often used as a flavouring for crÃªpes, and in the Vosges and the Massif Central bilberry tart (tarte aux myrtilles) is the most traditional dessert.

Constituents:—Quinic acid is found in the leaves, and a little tannin. Triturated with water they yield a liquid which, filtered and assayed with sulphate of iron, becomes a beautiful green, first of all transparent, then giving a green precipitate. The fruits contain sugar, etc.

Mrdicinal Uses:—The leaves can be used in the same way as those of UvaUrsi. The fruits are astringent, and are especially valuable in diarrhoea and dysentery, in the form of syrup. The ancients used them largely, and Dioscorides spoke highly of them. They are also used for discharges, and as antigalactagogues. A decoction of the leaves or bark of the root may be used as a local application to ulcers, and in ulceration of the mouth and throat.

The fruit is helpful in scurvy and urinary complaints, and when bruised with the roots and steeped in gin has diuretic properties valuable in dropsy and gravel. A tea made of the leaves is also a remedy for diabetes if taken for a prolonged period.

Bilberry is often said to improve night vision, and the story is told of RAF pilots in World War II using bilberry for that purpose. A recent study by the U.S. Navy found no effect, however, and the origins of the RAF story are unclear; it does not appear to be well known in the RAF itself.. Studies have shown that bilberry can reduce or reverse effects of degenerative eye disorders such as macular degeneration. The overall therapeutic use of bilberry is still clinically unproven.

Bilberry is primarily used for eye conditions and to strengthen blood vessels. During World War II, British Royal Air Force pilots reportedly found that eating bilberry jam just before a mission improved their night vision which prompted researchers to investigate bilberry’s properties.

Bilberry is also used for glaucoma, macular degeneration, diabetic retinopathy and cataracts.

The anthocyanins in bilberry may strengthen the walls of blood vessels, reduce inflammation and stabilize tissues containing collagen, such as cartilage, tendons and ligaments. Grape seed contains similar substances, however, bilberry’s anthocyanins are thought to have particular benefits for the eye.

Because bilberry is thought to strengthen blood vessels, it’s sometimes taken orally for varicose veins and hemorrhoids.
It may have other beneficial effects on capillaries due to the strong antioxidant properties of its anthocyanidin flavonoids.

The leaves have historically been used to treat gastrointestinal ailments, applied topically or made into infusions. The effects claimed have not been reproduced in the laboratory, however.

Bilberries were also collected at Lughnassadh, the first traditional harvest festival of the year, as celebrated by the Gaelic people. The crop of billberries was said to indicate how well the rest of the crops would fare in their harvests later in the year.
