The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, insects.Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers moist soil.

Cultivation:
Prefers a sunny position in a light well-drained soil. The bulbs should be planted fairly deeply. Most members of this genus are intolerant of competition from other growing plants. Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes. This plant is a bad companion for alfalfa, each species negatively affecting the other. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – sow spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle – if you want to produce clumps more quickly then put three plants in each pot. Grow them on in the greenhouse for at least their first winter and plant them out into their permanent positions in spring once they are growing vigorously and are large enough. Division in spring. The plants divide successfully at any time in the growing season, pot up the divisions in a cold frame or greenhouse until they are growing well and then plant them out into their permanent positions.

Edible Uses:

Bulb – raw or cooked. Used as a flavouring. The small bulbs are usually less than 2cm in diameter. Leaves – raw or cooked. Flowers – raw. Used as a garnish on salads.

Medicinal Uses:
Although no specific mention of medicinal uses has been seen for this species, members of this genus are in general very healthy additions to the diet. They contain sulphur compounds (which give them their onion flavour) and when added to the diet on a regular basis they help reduce blood cholesterol levels, act as a tonic to the digestive system and also tonify the circulatory system.

Other Uses
Repellent.

The juice of the plant is used as a moth repellent. The whole plant is said to repel insects and moles

Known Hazards Although no individual reports regarding this species have been seen, there have been cases of poisoning caused by the consumption, in large quantities and by some mammals, of certain members of this genus. Dogs seem to be particularly susceptible

Botanical Name : Allium ampeloprasum
Family: Amaryllidaceae
Subfamily: Allioideae
Tribe: Allieae
Genus: Allium
Species: A. ampeloprasum
Kingdom: Plantae
Order: Asparagales

Synonyms: Allium adscendens Kunth, Allium albescens Guss.

Common Name : Wild Leek, Broadleaf wild leek

Habitat : Allium ampeloprasum is native range is southern Europe to western Asia, but it is cultivated in many other places and has become naturalized in many countries. It grows on rocky places near the coast in S.W. England and Wales.
Description:
Allium ampeloprasum is a bulb growing to 1.8 m (6ft) by 0.1 m (0ft 4in). It produces bulbs up to 3 cm across. Scapes are round in cross-section, each up to 180 cm tall, bearing an umbel of as many as 500 flowers. Flowers are urn-shaped, up to 6 mm across; tepals white, pink or red; anthers yellow or purple; pollen yellow.
It is not frost tender. It is in leaf 8-Oct It is in flower from Jul to August, and the seeds ripen in August.

CLICK & SEE THE PICTURES
The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, insects.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in heavy clay soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils.
It cannot grow in the shade. It prefers dry or moist soil. The plant can tolerates strong winds but not maritime exposure.

Allium ampeloprasum has been differentiated into three cultivated vegetables, namely leek, elephant garlic and kurrat.

Cultivation:
Prefers a sunny position in a light well-drained soil. Prefers a dry position. Succeeds in clay soils. Tolerates a pH in the range 5.2 to 8.3. The bulbs should be planted fairly deeply. The wild leek is a rare native of Britain, found only in the south-west and Wales, though it should be hardy in most parts of the country. It comes into growth in the autumn, dying down in the summer, and makes a very pleasant winter leaf, either raw or cooked. It is a rather variable plant, especially in the amount of flowers and bulbils produced. The species produces mainly flowers with almost no bulbils, whilst the sub-species A. ampeloprasum babbingtonii (Babbington’s Leek) produces lots of bulbils and almost no flowers. The cultivated leek (A. ampeloprasum porrum) is believed to have been developed from this plant whilst, in Germany and Italy, other forms have been selected for their edible bulbils. The cultivar ‘Perizweibel’ is often used, the bulbils are solid rather than made up of layers and are popularly used for making pickles. This cultivar does not set seed. Another cultivated form of this plant produces very large, mild-garlic flavoured bulbs that are up to 500g in weight.They are known as elephant garlic. The wild leek grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes. This plant is a bad companion for alfalfa, each species negatively affecting the other. Members of this genus are rarely if ever troubled by browsing deer.
Propagation:
Seed – best sown as soon as it is ripe in a cold frame, though it can also be sown in a cold frame in the spring. Prick out the seedlings into individual pots when they are large enough to handle. Well-grown plants can be planted out into their final positions in late summer or the autumn, otherwise grow them on for a further year in pots and plant them out the following summer. Division in late summer or early autumn. Dig up the bulbs when the plants are dormant and divide the small bulblets at the base of the larger bulb. Replant immediately, either in the open ground or in pots in a cold frame. Bulbils – plant out as soon as they are ripe in late summer. The bulbils can be planted direct into their permanent positions, though you get better results if you pot them up and plant them out the following spring.
Edible Uses:
Edible Parts: Flowers; Leaves; Root.

Bulb – raw or cooked. The small bulbs can vary considerably in size from 2 – 6cm, they have a fairly strong leek to garlic flavour and are nice as a flavouring in cooked foods. The bulbs of selected cultivars are very large with a mild garlic flavour. Leaves – raw or cooked. A pleasant mild to strong garlic flavour, they are available from late autumn to the spring though they can become rather tough and fibrous as they get older. Flowers – raw. A similar flavour to the leaves but they have a somewhat dry texture and are best used as a flavouring in cooked foods. The bulbils have a mild garlic flavour and make a nice flavouring in salads and cooked foods. Although produced abundantly, they are quite fiddly to use because they are small. They can also be pickled.
Medicinal Uses:
Anthelmintic; Antiasthmatic; Anticholesterolemic; Antiseptic; Antispasmodic; Cholagogue; Diaphoretic; Diuretic;
Expectorant; Febrifuge; Stimulant; Stings; Stomachic; Tonic; Vasodilator.
This species has the same medicinal virtues as garlic, but in a much milder and less effective form. These virtues are as follows:- Garlic has a very long folk history of use in a wide range of ailments, particularly ailments such as ringworm, Candida and vaginitis where its fungicidal, antiseptic, tonic and parasiticidal properties have proved of benefit. It is also said to have anticancer activity. Daily use of garlic in the diet has been shown to have a very beneficial effect on the body, especially the blood system and the heart. For example, demographic studies suggest that garlic is responsible for the low incidence of arteriosclerosis in areas of Italy and Spain where consumption of the bulb is heavy. The bulb is said to be anthelmintic, antiasthmatic, anticholesterolemic, antiseptic, antispasmodic, cholagogue, diaphoretic, diuretic, expectorant, febrifuge, stimulant, stomachic, tonic, vasodilator. The crushed bulb may be applied as a poultice to ease the pain of bites, stings etc.
Other Uses:
Repellent.

The juice of the plant is used as a moth repellent. The whole plant is said to repel insects and moles.

Known Hazards : Although no individual reports regarding this species have been seen, there have been cases of poisoning caused by the consumption, in large quantities and by some mammals, of certain members of this genus. Dogs seem to be particularly susceptible.

Aloe vaera

Botanical NameAloe Perryi, Aloe vaera (LINN)

Family: Asphodelaceae
Subfamily: Asphodeloideae
Genus: Aloe
Species: A. perryi
Kingdom: Plantae
Clade: Angiosperms
Clade: Monocots
Order: Asparagales

Common Name: Socotrine aloe.

Habitat: –Aloes are indigenous to East and South Africa, but have been introduced into the West Indies (where they are extensively cultivated) and into tropical countries, and will even flourish in the countries bordering on the Mediterranean. These plants are mainly found in dry areas; on flat or gentle slopes, primarily on limestone pavement but occasionally on sandy plains or granite mountains; at elevations from sea-level to 900 metres.

Description:
Aloe Perryi or Aloveras are succulent plants belonging to the Lily family, with perennial, strong and fibrous roots and numerous, persistent, fleshy leaves, proceeding from the upper part of the root, narrow, tapering, thick and fleshy, usually beset at the edges with spiney teeth. Many of the species are woody and branching. In the remote districts of S.W. Africa and in Natal, Aloes have been discovered 30 to 60 feet in height, with stems as much as 10 feet in circumference.

The flowers are produced in erect, terminal spikes. There is no calyx, the corolla is tubular, divided into six narrow segments at the mouth and of a red, yellow or purplish colour. The capsules contain numerous angular seeds.

The true Aloe is in flower during the greater part of the year and is not to be confounded with another plant, the Agave or American Aloe (Agave Americana), which is remarkable for the long interval between its periods of flowering. This is a succulent plant, without stem, the leaves being radical, spiney, and toothed. There is a variety with variegated foliage. The flower-stalk rises to many feet in height, bearing a number of large and handsome flowers. In cold climates there is usually a very long interval between the times of its flowering, though it is a popular error to suppose that it happens only once in a hundred years for when it obtains sufficient heat and receives a culture similar to that of the pineapple, it is found to flower much more frequently. Various species of Agave, all of which closely resemble each other, have been largely grown as ornamental plants since the first half of the sixteenth century in the south of Europe, and are completely acclimatized in Spain, Portugal and Southern Italy, but though often popularly called Aloes all of them are plants of the New World whereas the true Aloes are natives of the Old World. From a chemical point of view there is also no analogy at all between Aloes and Agaves.

CLICK & SEE THE PICTURES

Although the Agave is not employed medicinally, the leaves have been used in Jamaica as a substitute for soap, the expressed juice (a gallon of the juice yields about 1 lb. of the soft extract), dried in the sun, being made into balls with wood ash. This soap lathers with salt water as well as fresh. The leaves have also been used for scouring pewter and kitchen utensils. The inner spongy substance of the leaves in a decayed state has been employed as tinder and the fibres may be spun into a strong, useful thread.

The fleshy leaves of the true Aloe contain near the epidermis or outer skin, a row of fibrovascular bundles, the cells of which are much enlarged and filled with a yellow juice which exudes when the leaf is cut. When it is desired to collect the juice, the leaves are cut off close to the stem and so placed that the juice is drained off into tubs. This juice thus collected is concentrated either by spontaneous evaporation, or more generally by boiling until it becomes of the consistency of thick honey. On cooling, it is then poured into gourds, boxes, or other convenient receptacles, and solidifies.

Aloes require two or three years’ standing before they yield their juice. In the West Indian Aloe plantations they are set out in rows like cabbages and cutting takes place in March or April, but in Africa the drug is collected from the wild plants.

Cultivation:
A plant of mainly arid and semi-arid lowland areas in the tropics. It grows best in areas where annual daytime temperatures are within the range 22 – 27°c, but can tolerate 12 – 31°c. It can be killed by temperatures of 5°c or lower It prefers a mean annual rainfall in the range 400 – 700mm, but tolerates 250 – 1,400mm. Tolerant of poor soils. Requires a well-drained, light to medium soil and a position in full sun. Prefers a pH in the range 6.5 – 7, tolerating 6 – 7.5.

Aloe species follow the Crassulacean acid metabolism (CAM). CAM plants can fix carbon dioxide at night and photosynthesize with closed stomata during the day, thus minimizing water loss. This, plus their succulent leaves and stems, and the presence of a thick cuticle, makes them well adapted to dry conditions.

Propagation:
Seed – we have no specific information on this species – in general Aloes are sown in a sandy, well-drained potting soil in a warm, shady position in standard seed trays. Germination takes about three weeks. Cover the seed with a thin layer of sand (1 – 2mm), keep moist. The seedlings can be planted out in individual bags or containers as soon as they are large enough to handle.

Constituents:
The most important constituents of Aloes are the two Aloins, Barbaloin and Isobarbaloin, which constitute the so-called ‘crystalline’ Aloin, present in the drug at from 10 to 30 per cent. Other constituents are amorphous Aloin, resin and Aloe-emodin. The proportion in which the Aloins are present in the respective Aloes is not accurately known.

The manner in which the evaporation is conducted has a marked effect on the appearance of the Aloes, slow and moderate concentration tending to induce crystallization of the Aloin, thus causing the drug to appear opaque. Such Aloes is termed ‘livery’ or hepatic, and splinters of it exhibit minute crystals of Aloin when examined under the microscope. If, on the other hand, the evaporation is carried as far as possible, the Aloin does not crystallize and small fragments of the drug appear transparent; it is then termed ‘glassy,’ ‘vitreous,’ or ‘lucid’ Aloes and exhibits no crystals of Aloin under the microscope.

Medicinal Uses:
Used medicinally in the same ways as Aloe vera Aloe vera is used in the following ways:-

The clear gel contained within the leaf makes an excellent treatment for wounds, burns and a host of other skin disorders, placing a protective coat over the affected area, speeding up the rate of healing and reducing the risk of infection. The gel is also applied externally to cure haemorrhoids. These actions are in part due to the presence of aloectin B, which stimulates the immune system. To obtain this gel, the leaves can be cut in half along their length and the inner pulp rubbed over the affected area of skin. This has an immediate soothing effect on all sorts of burns and other skin problems.
The use of the gel has been approved in the United States for the treatment of leukaemia in cats, of fibrosarcoma in dogs, for wound healing in humans and to prevent dry socket (‘alveolar osteitis’) in humans.
The peeled leaves are eaten to relieve sore throat and coughs and as a mild laxative. As a food supplement, the leaf gel is said to facilitate digestion, and to improve blood and lymphatic circulation, as well as kidney, liver and gall bladder functions. There are claims of beneficial activity of Aloe vera products in cases of AIDS, arthritis, or other chronic and debilitating conditions. However, these claims have not been substantiated by scientific studies. There is also no evidence that topical Aloe vera gel is effective in preventing or minimizing radiation-induced skin reactions in cancer patients. In large amounts, the gel has anti-irritant properties.

A bitter substance is obtained from the yellow sap at the base of the leaf. Known as ‘bitter aloes’, it contains anthraquinones which are a useful digestive stimulant and a strong laxative. It also has vermicidal properties. It is taken internally in the treatment of chronic constipation, poor appetite, digestive problems etc. Mixed with other ingredients to mask its bitter taste, it is taken against asthma and to treat coughs. Similar mixtures are taken to cure dysentery, kidney problems or against dyspepsia. It should be administered preferably in combination with an antispasmodic to moderate its griping action.

It is applied externally as a refrigerant to treat acne or cuts.
‘Curaçao aloe’ should contain at least 28% hydroxy-anthraquinone derivatives; it is almost entirely soluble in 60% alcohol and for more than 70% in water. It should not contain more than 12% moisture and 3% ash.The plant is strongly purgative so great care should be taken over the dosage.
Anthraquinone-based laxatives, such as bitter aloes, should not be used longer than 8 – 10 days, nor by children younger than 12 years. Contra-indications include pregnancy, breastfeeding, intestinal inflammations and haemorrhoids.
When plants are grown in pots the anthraquinone content is greatly reduced.

The word Aloes, in Latin Lignum Aloes, is used in the Bible and in many ancient writings to designate a substance totally distinct from the modern Aloes, namely the resinous wood of Aquilaria agallocha, a large tree growing in the Malayan Peninsula. Its wood constituted a drug which was, down to the beginning of the present century, generally valued for use as incense, but now is esteemed only in the East.

A beautiful violet colour is afforded by the leaves of the Socotrine Aloe, and it does not require a mordant to fix it.
Known Hazards: The sap of Aloe species contains anthraquinones. These compounds have several beneficial medicinal actions, particularly as a laxative, and many species of Aloe are thus employed in traditional medicine. Whilst safe in small doses and for short periods of time, anthraquinones do have potential problems if used in excess. These include congestion and irritation of the pelvic organs.

Long term use of anthraquinone laxatives may also play a role in development of colorectal cancer as they have genotoxic potential, and tumorigenic potential.
