The plant is a very popular herbal medicine that has a history of use dating back to at least 400 BC. It is widely cultivated, from warm temperate to tropical regions, as a medicinal plant and ingredient of skin care products. It is also commonly grown as an ornamental in gardens and as a pot plant in regions where it is not warm enough to grow it outdoors.

Known Hazards

Aloe vera is very widely used as a herbal remedy. Whilst the leaf gel is entirely safe, the bitter aloes found at the base of the leaves contain anthraquinones which have potential problems if used in excess. The possible side effects of anthraquinones include congestion and irritation of the pelvic organs[

Aloe vera plants take about 3 years to attain harvestable size, and then leaves can be harvested for about seven years. The exudate is collected by cutting off the leaves transversely close to the stem and positioning them in such a way that the juice drains into pots, tubs, vessels or even a simple canvas placed over a depression in the ground. The exudate may also be obtained by squeezing the leaves or by warm or cold water retting. The leaves are usually cut in the morning and it takes 4 - 5 hours for the juice to drain from a pile of leaves. Only older leaves are cut; younger ones and growing tips are spared[

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[

Aloe vera gel has earned a reputation as a miracle drug. It is effective in burn treatment, because of its anti-inflammatory and wound-healing properties. Its healing properties may be due to rehydrating, insulating and protective activities resulting from the high water content. The major constituents are polysaccharides (mainly acemannan), lectins, sterols and enzymes, and the effect is assumed to be a synergy between the polysaccharide base and various components. In addition, acemannan has shown immune stimulating, anticancer and antiviral effects[

Several studies on both topical and oral treatments with the gel have shown a positive influence on the synthesis of glycosamino glycans, thereby facilitating wound healing.
A placebo-controlled, double-blind study showed that a topically applied gel of 0.5% in a hydrophylic cream is beneficial for patients suffering from psoriasis. It did not show toxic or other side-effects.
A clinical test with patients with advanced solid tumours, for whom no standard effective therapy was available, suggested that the gel, in combination with the immunomodulating neurohormone melatonin, may produce some therapeutic benefits, at least in terms of stabilization of disease and survival.
The dried exudate of bitter aloes contains 15 - 40% anthraquinone derivatives such as aloin and hydroxyaloins. Furthermore, the exudate contains the pyrone derivative aloenin and aloeresins[

Contradicting results of clinical tests with Aloe vera products are common. A problem is that the identity of the tested plants is not always certain. A second problem is that the products are not of standard composition, but depend on cultivar, growing conditions and handling after harvest. Therefore, commercial products may vary enormously in composition. Also, contamination of the gel with exudate can turn a harmless product into a purgative. It is therefore imperative that products of well-defined composition are used for clinical trials, that the identity of the plant is confirmed by a taxonomist and that a specimen is deposited in a herbarium for future reference[
