I have used Aloe vera in my practice over the years whenever I feel it to be necessary … it is such a wonderful plant.
Stephen Turoff, one of the most gifted healers in Britain today, recommends Aloe as a general tonic and says that it is especially valuable in treating digestive disorders. In his view:
Aloe vera is good for everything…
Botanical, Historical and Cultural Origins
ALOE VERA
Most sources place Aloe in the Lily family (Liliaceae). Until recently this was correct, but according to Dr Tom Reynolds of the Jodrell Laboratory, Kew Gardens, London, it has now been designated its own family, known as Aloaceae. Nonetheless, it is related to the lily family and to plants such as garlic, onion and asparagus, all of which are known to have medicinal properties.
The Royal Horticultural Society Gardeners’ Encylopaedia of Plants and Flowers defines Aloe as:
[A] Genus of evergreen, rosetted trees, shrubs, perennials and scandent climbers with succulent foliage and tubular to bell-shaped flowers.1
There are about 350 varieties of Aloe in the Aloaceae family. In South Africa alone, 132 species were recorded in 1955! They range from miniature aloes like Aloe aristata and Aloe brevifolia to small aloes such as Aloe striata, which is one of the prettiest of the species. Its leaves are pale green edged with light coral red and sometimes flushed with pink. The flowers are orange or pinky-red and roughly resemble a mass of coral. The flowers of different aloes vary in colour from cream or orange to scarlet, rose flame or spectacular autumn tints.
Among the large aloes are Aloe arborescens and Aloe ferox, both used for healing purposes. In the 19th century, James Backhouse, in A Narrative of a Visit to Mauritius and South Africa, refers to Aloe arborescens as a Tree-Aloe, otherwise known as ‘Kokerboom’ in the Afrikaans language. ‘Kokerboom’ means Quiver Tree, as it was used by the Bushmen to make quivers from its branches. Members of the Aloaceae family known for their medicinal properties include:
The origins of Aloe vera is not clearly known. Some writers claim it comes from southern Africa, others from northern Africa. One of the most authoritative botanical sources, Mr Nigel Hepper, retired senior botanist at Kew Gardens, has suggested that it may come from the Yemen. This has not been proven, but the Aloe vera plant has been found in the Yemen in remote places where it was clearly not transplanted from another region. It has also been found in Tenerife in mountainous areas. In the light of early Egyptian and Mesopotamian records, it most likely comes from either the Yemen or North Africa.
Aloe vera is a clump-forming, perennial succulent with basal rosettes of tapering, thick leaves, mottled green, later turning grey-green. It is a cactus-like plant with distinctive spiky leaves whose flower stems carry bell-shaped yellow flowers in summer. From the centre of the dark green leaves of the Aloe vera plant, the flower stems, which are leafless, can reach 1.5 m (3 ft) in length and have attractive tubular-shaped bells.
The Aloe vera plant is characterized by its long tapering sharp leaves with ribbed thorny ridges along the spine. The fleshy leaves grow in a spiral shape to form a rosette pattern. This rosette pattern is a distinctive feature of Aloe vera. The soft fleshy leaves of the Aloe vera exude a watery gel or juice when cut, and contain the plant’s two main medicinal products:
1 the sap from the rind, known as the exudate
2 the gel/juice, used extensively in healing.
The leaves themselves can also be dried and made into powder (for use in beauty products). All medical aloes, however, produce a typical bitter yellowish or reddish sap which is their common characteristic.
All Aloes are part of a larger genus called Xeroids, which implies an ability to ‘shut down’ the pores (or ‘stomata’, tiny openings in the epidermis of the leaf) to ensure that water is retained within the plant. In this way they can survive long periods without water. This same ability to close the stomata in the leaf also apparently facilitates the almost miraculous closing of any wound or damage to the outer skin of the plant. The power to heal itself so rapidly and re-grow in another direction doubtless pointed the way to its use as a wound treatment.
The Aloe vera plant takes about four years to mature, by which time the gel in the outer leaves is at its most potent. When fully grown the individual leaves can reach a height of 60 to 90 cm (2 to 3 ft) and each leaf can weigh approximately 1.5 to 2 kg (3 to 4 lb). Each plant usually has 12 to 16 leaves. As a perennial, Aloe vera lives for about 12 years. When the outer leaves are harvested, up to three times a year, the plant is able to close itself down against water loss. Within a few seconds of being cut, the plant films over the wound and a protective coating forms which stops loss of sap. The outer leaves are always harvested first, allowing the inner leaves time to develop their ripeness and potency.
Although Aloe is ideally suited to growing in hot, arid climates, it can be grown in glasshouses or indoors in Europe. As it is frost-sensitive it should always be kept in warm conditions, requiring a minimum temperature of 7–10°C (45–50°F). However, although frost can kill them, the plants seldom die simply from exposure to cold unless they are very young. Tree Aloes and shrubs with a spread over 30 cm (1 ft) prefer full sun;
