Botanical Name: Betula pubescens
Family: Betulaceae
Genus: Betula
Subgenus: Betula
Species: B. pubescens
Kingdom: Plantae
Order: Fagales

Synonyms: Betula alba var. pubescens, Betula alba subsp. pubescens

Common Names: Downy birch, Moor birch, White birch, European white birch or Hairy birch

Habitat:Betula pubescens is native to Most of Europe, including Britain, east to W. Siberia and central Asia. It grows on open woodland and heaths, usually on acid soils, from sea level to 830 metres.

Description:
Betula pubescens is a deciduous tree growing to 10 to 20 m (33 to 66 ft) tall (rarely to 27 m), with a slender crown and a trunk up to 70 cm (28 in) (exceptionally 1 m) diameter, with smooth but dull grey-white bark finely marked with dark horizontal lenticels. The shoots are grey-brown and finely downy. The leaves are ovate-acute, 2 to 5 cm (0.8 to 2.0 in) long and 1.5 to 4.5 cm (0.6 to 1.8 in) broad, with a finely serrated margin. The flowers are wind-pollinated catkins, produced in early spring before the leaves. The fruit is a pendulous, cylindrical aggregate 1 to 4 cm (0.4 to 1.6 in) long and 5 to 7 mm (0.2 to 0.3 in) wide which disintegrates at maturity, releasing the individual seeds; these are 2 mm (0.08 in) long with two small wings along the side……CLICK & SEE THE PICTURES
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay and nutritionally poor soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid soils. It cannot grow in the shade. It prefers dry moist or wet soil. The plant can tolerates strong winds but not maritime exposure.

Cultivation:
Succeeds in a well-drained light loamy soil in a sunny position. Grows well in heavy clay soils. Tolerates a wet position, succeeding in poorly drained soils. Fairly wind tolerant. Prefers an acid soil. A very ornamental tree and fast growing, capable of growing 1 metre a year but it is short-lived. It is one of the first trees to colonize open land and it creates a suitable environment for other woodland trees to follow. These trees eventually shade out the birch trees. Trees take about 15 years from seed to produce their own seed. Although closely related, it does not usually hybridize with B. pendula. It hybridizes freely with B. pendula according to another report. A superb tree for encouraging wildlife, it has over 200 associated insect species. A good plant to grow near the compost heap, aiding the fermentation process. It is also a good companion plant, its root activity working to improve the soil. 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:
Inner bark – cooked or dried, ground into a powder then used with cereals for making bread etc. 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. Harvested in early spring, before the leaves unfurl, by tapping the trunk. The flow is best on sunny days following a heavy frost. The sap is often concentrated into a sugar by boiling off the water. Between 4 and 7 litres can be drawn off a mature tree in a day and this will not kill the tree so long as the tap hole is filled up afterwards. However, prolonged or heavy tapping will kill the tree. A beer can be fermented from the sap. 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.”. Young leaves – raw or cooked. Young catkins. A tea is made from the leaves and another tea is made from the essential oil in the inner bark.
Medicinal Uses:

Anti-inflammatory, cholagogue, diaphoretic. The bark is diuretic and laxative. The inner bark is bitter and astringent, it is used in treating intermittent fevers. An oil obtained from the inner bark is astringent and is used in the treatment of various skin afflictions, especially eczema and psoriasis. The bark is usually obtained from trees that have been felled for timber and can be distilled at any time of the year. The buds are balsamic. The young shoots and leaves secrete a resinous substance which has acid properties, when combined with alkalis it is a tonic laxative. The leaves are anticholesterolemic and diuretic. They also contain phytosides, which are effective germicides. An infusion of the leaves is used in the treatment of gout, dropsy and rheumatism, and is recommended as a reliable solvent of kidney stones. The young leaves and leaf buds are harvested in the spring and dried for later use. A decoction of the leaves and bark is used for bathing skin eruptions. The vernal sap is diuretic. The boiled and powdered wood has been applied to chafed skin. Moxa is made from the yellow fungous excrescences of the wood, which sometimes swell out of the fissures. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Betula species for infections of the urinary tract, kidney and bladder stones, rheumatism.

Other Uses:
Adhesive; Besom; Charcoal; Compost; Dye; Essential; Fibre; Fungicide; Miscellany; Paper; Pioneer; Polish; Repellent; Tannin; Thatching; Waterproofing; Wood.

The bark is used to make drinking vessels, canoe skins, roofing tiles etc. It is waterproof, durable, tough and resinous. Only the outer bark is removed, this does not kill the tree. It is most easily removed in late spring to early summer. The bark was pressed flat and stored until the following spring. When required for making canoes it would be heated over a fire to make it pliable for shaping to the canoe frame. A pioneer species, it readily invades old fields, cleared or burnt-over land and creates conditions suitable for other woodland trees to become established. Since it is relatively short-lived and intolerant of shade, it is eventually out-competed by these trees. A tar-oil is obtained from the white bark in spring. It has fungicidal properties and is also used as an insect repellent. It makes a good shoe polish. Another report says that an essential oil is obtained from the bark and this, called ‘Russian Leather’ has been used as a perfume. A glue is made from the sap. Cordage can be made from the fibres of the inner bark. This inner bark can also be separated into thin layers and used as a substitute for oiled paper. A decoction of the inner bark is used to preserve cordage, it is rich in tannin. The bark contains up to 16% tannin. A brown dye is obtained from the inner bark. An oil similar to Wintergreen oil (obtained from Gaultheria procumbens) is obtained from the inner bark. It is used medicinally and also makes a refreshing tea. The young branches are very flexible and are used to make whisks, besoms etc. They are also used in thatching and to make wattles. The leaves are a good addition to the compost heap, improving fermentation. A black paint is obtained from the soot of the plant[61]. A high quality charcoal is obtained from the bark. It is used by artists, painters etc. Wood – soft, light, durable. It is used for a wide range of purposes including furniture, tool handles, carving, toys etc. It is a source of charcoal that is used by artists and is also pulped and used for making paper.

Known Hazards: The aromatic and aliphatic hydrocarbons in birch tar are irritating to the skin. Do not use in patients with oedema or with poor kidney or heart functions.

Alnus nepalensis

 

[amazon_link asins=’B004V3P3BI,B004V3P4G2′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’5cfa41bc-8af3-11e7-bbe8-39692a1b4bd1′]

Botanical Name : Alnus nepalensis
Family: Betulaceae
Genus: Alnus
Subgenus: Alnus
Species: A. nepalensis
Kingdom: Plantae
Order: Fagales

Common Names: Utis in Nepali and Nepalese alder in English.

Habitat : Alnus nepalensis occurs throughout the Himalaya at 500–3000 m of elevation from Pakistan through Nepal and Bhutan to Yunnan in southwest China. It grows best on deep volcanic loamy soils, but also grows on clay, sand and gravel. It tolerates a wide variety of soil types and grows well in very wet areas. It needs plenty of moisture in the soil and prefers streamside locations, but also grows on slopes.

Description:
Alnus nepalensis is a large deciduous alder tree with silver-gray bark that reaches up to 30 m in height and 60 cm in diameter. The leaves are alternate, simple, shallowly toothed, with prominent veins parallel to each other, 7–16 cm long and 5–10 cm broad. The flowers are catkins, with the male and female flowers separate but produced on the same tree. The male flowers are 10 to 25 cm (4 to 10 in) long and pendulous, while the female flowers are erect, 1 to 2 cm (0.4 to 0.8 in), with up to eight together in axillary racemes. Unusually for an alder, they are produced in the autumn, with the seeds maturing the following year.

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.It can fix Nitrogen…….CLICK TO SEE THE PICTURES

Suitable for: medium (loamy) and heavy (clay) soils and can grow in heavy clay and nutritionally poor soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist or wet soil.

Cultivation:
Prefers a heavy soil and a damp situation. Grows well in heavy clay soils. Succeeds in very infertile sites. The Nepalese alder is reported to tolerate clay, flooding, fog, gravel, sand, shade, slope, water-logging, and weeds. It is not tolerant of high winds. Grows best in deep well-drained loams or loamy soils of alluvial soils, but ranges from gravel to sand to clay. Prefers an annual rainfall estimated at 50 – 250cm, an annual average temperature in the range of 19 – 23°C, and a pH of 6 – 8. This species is possibly only hardy in the milder areas of Britain. This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.

Propagation:
Seed – best sown in a cold frame as soon as it is ripe and only just covered. Spring sown seed should also germinate successfully so long as it is not covered. The seed should germinate in the spring as the weather warms up. When large enough to handle, prick the seedlings out into individual pots. If growth is sufficient, it is possible to plant them out into their permanent positions in the summer, otherwise keep them in pots outdoors and plant them out in the spring. If you have sufficient quantity of seed, it can be sown thinly in an outdoor seed bed in the spring. The seedlings can either be planted out into their permanent positions in the autumn/winter, or they can be allowed to grow on in the seed bed for a further season before planting them. Cuttings of mature wood, taken as soon as the leaves fall in autumn, outdoors in sandy soil.

Medicinal Uses:
A useful diuretic for reducing swelling of the leg. The juice of the bark is boiled and the gelatinous liquid applied to burns.

Other Uses:
Dye; Fuel; Soil stabilization; Wood.

The bark contains 7% tannin, it is used in dyeing and tanning. It is used to deepen the red colour of madder, Rubia cordifolia. A fast growing species, it is suitable for plantation cultivation in tropical uplands. The tree is locally cultivated by West Java Forest Service to reforest eroded slopes under ever-wet climates. The tree establishes rapidly on areas subject to landslides, binding the soil with its extensive root system and stabilizig the slope. Wood – soft, tough, even grained, rather durable, easily sawn, seasons well and does not warp. It is used to a limited extent in carpentry, house construction, tea boxes, for making furniture, rope bridges etc. A very good timber, it deserves to be more widely used. In India the trees are coppiced every two years for fuel.

The Natural Cancer-Fighting Power of Tomatoes and Broccoli

[amazon_link asins=’B016YOW2NS,B014YZGQKY,B01C59ZNZK,B00JAB0VHW,B06XZGHZCP,B00ATPBOVU,B071HWMVPX,B002DYSNZU,B0722JVPM2′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’0a28cfe2-607b-11e7-bd8e-25137d819824′]

Broccoli and tomatoes, both of which have been previously found to help fight cancer, have been found to be even more effective against prostate cancer when eaten together as part of a daily diet.

CLICK & SEE

Researchers fed rats who hd been implanted with prostate cancer cells a diet containing 10 percent broccoli powder and 10 percent tomato powder for a period of 22 weeks.

Other rats received either one or the other but not both, a dose of lycopene (the substance in tomatoes believed fight cancer), or the drug finasteride. Another set of rats was castrated.

At the end of the study, the tomato and broccoli combination diet was the most effective treatment; only castration even came close in terms of effectiveness.

The combination of vegetables may be more effective than either one alone because different compounds in each food work on different anti-cancer pathways.

Considering that nearly all of the conventional prostate cancer treatments may be unnecessary and harmful to your health, still more confirmation about a natural and completely healthy whole food treatment that doesn’t involve a toxic drug or dangerous procedure.

Even eating tomato sauce a couple of times a week may reduce prostate cancer risk, and the diet suggested by this study — 1.4 cups of fresh broccoli and 1/2 cup of tomato paste daily — is easily doable by those who wish to reduce their risk.

Still, it’s very important to realize, despite the good news, no food or vegetable is ideal for everyone. One of the best things you can do to honor your body, among many to virtually eliminate your cancer risks, remains eating the best foods for your unique metabolic type.

However, one of the most valuable and important natural approaches you can have to avoid prostate cancer is to make sure you have adequate sun exposure on your skin. There is overwhelming compelling evidence that optimal vitamin D levels are highly protective against prostate cancer.
