Botanical Name : Rubus idaeus
Synonyms: -Raspbis. Hindberry. Bramble of Mount Ida.
Common Names :Raspberry, also called red raspberry or occasionally as European raspberry
Habitat : Raspberry is native to Europe and northern Asia
Raspberry is generally a perennial plant which bears biennial stems (“canes”) from a perennial root system. In its first year, a new, unbranched stem (“primocane”) grows vigorously to its full height of 1.5-2.5 m, bearing large pinnately compound leaves with five or seven leaflets, but usually no flowers. In its second year (as a “floricane”), a stem does not grow taller, but produces several side shoots, which bear smaller leaves with three or five leaflets. The flowers are produced in late spring on short racemes on the tips of these side shoots, each flower about 1 cm diameter with five white petals. The fruit is red, edible, and sweet but tart-flavoured, produced in summer or early autumn; in botanical terminology, it is not a berry at all, but an aggregate fruit of numerous drupelets around a central core. In raspberries (various species of Rubus subgenus Idaeobatus), the drupelets separate from the core when picked, leaving a hollow fruit, whereas in blackberries and most other species of Rubus, the drupelets stay attached to the core.

The well-known Raspberry, grown so largely for its fruit. It flowers in May and June.
Raspberry has several Species:
Examples of raspberry species in Rubus subgenus Idaeobatus include:
Rubus crataegifolius ,,,(Korean raspberry)
Rubus gunnianus (Tasmanian alpine raspberry)
Rubus idaeus (European red raspberry)
Rubus leucodermis (Whitebark or Western raspberry, Blue raspberry, Black raspberry)
Rubus occidentalis (Black raspberry)
Rubus parvifolius (Australian native raspberry)
Rubus phoenicolasius (Wine raspberry or Wineberry)
Rubus rosifolius (West Indian raspberry)
Rubus strigosus (American red raspberry) (syn. R. idaeus var. strigosus)
Rubus ellipticus (Yellow Himalayan Raspberry)
Several species of Rubus, also called raspberries, are classified in other subgenera, including:
Rubus arcticus (Arctic raspberry, subgenus Cyclactis)
Rubus deliciosus (Boulder raspberry, subgenus Anoplobatus)
Rubus nivalis (Snow raspberry, subgenus Chamaebatus)
Rubus odoratus (Flowering raspberry, subgenus Anoplobatus)
Rubus sieboldii (Molucca raspberry, subgenus Malachobatus)
Cultivation & propagation: The plant is generally propagated by suckers, though those raisedfrom layers should be preferred, because they will be better rooted and not so liable to send out suckers. In preparing these plants their fibres should be shortened, but the buds which are placed at a small distance from the stem of the plant must not be cut off, as they produce the new shoots the following summer. Place the plants about 2 feet apart in the rows, allowing 4 or 5 feet between the rows. If planted too closely, without plenty of air between the rows, the fruit will not be so fine.
The most suitable soil is a good, strong loam. They do not thrive so well in a light soil.
In October, cut down all the old wood that has produced fruit in the summer and shorten the young shoots to about 2 feet in length. Dig the spaces between the rows well and dress with a little manure. Beyond weeding during the summer, no further care is needed. It is wise to form new plantations every three or four years, as the fruit on old plants is apt to deteriorate.
Chemical Constituents: The Raspberry contains a crystallizable fruit-sugar, a fragrant volatile oil, pectin, citric and malic acids, mineral salts, colouring matter and water. The ripe fruit is fragrant, subacid and cooling: it allays heat and thirst, and is not liable to acetous fermentation in the stomach.
Vitamin C and phenolics are present in red raspberries. Most notably, the anthocyanins cyanidin-3-sophoroside, cyanidin-3-(2(G)-glucosylrutinoside) and cyanidin-3-glucoside, the two ellagitannins sanguiin H-6 and lambertianin C are present together with trace levels of flavonols, ellagic acid and hydroxycinnamate.
Polyphenolic compounds from raspberry seeds are efficient antioxidants. Raspberry ketones found in red raspberries are also marketed as having weight loss benefits, However, there is no clinical evidence for this effect in humans. The average estimated daily intake of dietary raspberry ketone has been estimated to be 0.42 mg/kg/day
It is a very delicious fruit to eat.
Raspberry vinegar is an acid syrup made with the fruit-juice, sugar and white-wine vinegar, and when added to water forms an excellent cooling drink in summer, suitable also in feverish cases, where the acid is not an objection. It makes a useful gargle for relaxed, sore throat.
A home-made wine, brewed from the fermented juice of ripe Raspberries, is antiscrofulous, and Raspberry syrup dissolves the tartar of the teeth.
Astringent and stimulant. Raspberry Leaf Tea, made by the infusion of 1 OZ. of the dried leaves in a pint of boiling water, is employed as a gargle for sore mouths, canker of the throat, and as a wash for wounds and ulcers. The leaves, combined with the powdered bark of Slippery Elm, make a good poultice for cleansing wounds, burns and scalds, removing proud flesh and promoting healing.
An infusion of Raspberry leaves, taken cold, is a reliable remedy for extreme laxity of the bowels. The infusion alone, or as a component part of injections, never fails to give immediate relief. It is useful in stomach complaints of children.
Raspberry Leaf Tea is valuable during parturition. It should be taken freely – warm.
Red raspberries contains 31 ?g/100 g of folate. Red raspberries have antioxidant effects that play a minor role in the killing of stomach and colon cancer cells.
Young roots of Rubus idaeus prevented kidney stone formation in a mouse model of hyperoxaluria. Tiliroside from raspberry is a potent tyrosinase inhibitor and might be used as a skin-whitening agent and pigmentation medicine.
Raspberry fruit may protect the liver.
Traditional lore suggests that pregnant women use raspberry leaf tea, especially as an aid in delivery. However, scientific research has found no evidence to support this claim. Every Woman’s Herbal claims that raspberry leaf tea will enrich the mother’s milk, especially during periods when the baby is going through a growth spurt.
There is considerable discussion around the possible benefits of raspberry leaf tea taken late in pregnancy. The consensus seems to be that while taking raspberry leaf tea should not be expected to bring the onset of labour forward, it might shorten the second stage of labour. A double-blind, randomized, placebo-controlled trial published in 2001 found that consumption of 2.4 g of raspberry leaf tablets, consumed from 32 weeks’ gestation until labor by low-risk nulliparous women did not shorten the first stage labor. The study observed a slight reduction in the second stage labor (9.6 minutes) and a forceps delivery rate that was 37% lower than that of the control group.
Most of the evidence available is anecdotal, and a recent scholarly review stressed concern at the lack of evidence for safety and efficacy and called recommendations of its use “questionable”
