Uses of Aloe vera extract

Topical aloe appears to inhibit infection and promote healing of minor burns and wounds, frostbite, as well as in skin affected by diseases such as psoriasis and seborrheic dermatitis, although studies have had conflicting results. Dried aloe latex should be ingested with caution as a drastic cathartic, but its use is not recommended. In 2002, the US Food and Drug Administration required all over-the-counter aloe laxative products to be removed from the US market or reformulated because manufacturers have not provided the necessary safety data.

Botany

Aloe vera extract , of which there are approximately 500 species, belong to the Liliaceae family. 1 The name, meaning “bitter and shiny substance,” derives from the Arabic alloeh . Indigenous to the Cape of Good Hope, these perennial succulents grow throughout most of Africa, southern Arabia and Madagascar, and are cultivated in Japan, North and South America, and in the Caribbean and Mediterranean regions. Often attractive ornamental plants, their fleshy leaves are stiff and spiny along the edges and grow in a rosette. Each plant has 15 to 30 tapering leaves, each up to 0.5 m long and 8 to 10 cm wide. Beneath the thick cuticle of the epidermis lies the chlorenchyma. Between this layer and the colorless mucilaginous pulp containing the aloe gel are numerous vascular bundles and inner bundle sheath cells from which a bitter yellow sap exudes when the leaves are cut. 2

History

Drawings of aloe have been found in the wall carvings of Egyptian temples erected in the 4th millennium BC. Called the “Plant of Immortality,” it was a traditional funerary gift for the pharaohs.  notes the use of aloe in curing infections, treating the skin, and preparing drugs that were chiefly used as laxatives. In the Bible, Nicodemus provided a mixture of myrrh and aloes for the preparation of Christ''s body. Alexander the Great (356 to 323 BC) is said to have conquered the island of Socotra to obtain control of aloe. In 74 AD, the Greek physician Dioscorides recorded its use to heal wounds, stop hair loss, treat genital ulcers, and eliminate hemorrhoids. In the 6th century AD, Arab traders carried it to Asia. From the Mediterranean region, it was carried to the New World in the 16th century by Spanish explorers and missionaries. In the modern era, its clinical use began in the 1930s as a treatment for roentgen dermatitis.

Chemistry

The aloe plant yields 2 commercially important products. Aloe vera extract is the solid residue obtained by evaporating the latex from the pericyclic cells beneath the skin. 3 The bitter yellow latex contains the anthraquinone barbaloin (a glucoside of aloe-emodin) and iso-barbaloin, as well as a series of O-glycosides of barbaloin (called aloinosides), chrysophanic acid, and up to 63% resin. The filtering of resins from the exudate and concentrating the remaining anthraglycoside material, which is up to 25% barbaloin, into crystalline form produces aloin, a mixture of water-soluble glycosides.

A second product, Aloe vera extract , is a clear, thin, gelatinous material obtained by crushing the mucilaginous cells found in the inner tissue of the leaf. Aloe vera extract is the product used most frequently in the cosmetic and health food industries.

 

Aloe vera extract is generally devoid of anthraquinone glycosides. Aloe vera extract contains a Polysaccharide glucomannan, similar to guar gum, that is believed to contribute mostly to the emollient effect. Aloe vera gel “extract” is not actually an extract, but rather the pulverized whole leaves of the plant.
