Molecular Structure::

Aloe vera, also known as the medicinal aloe, is a species of succulent plant that probably originated in Northern Africa. Aloe vera grows in arid climates and is widely distributed in Africa and other arid areas. Aloe vera is a stemless or very short-stemmed succulent plant growing to 60–100 cm (24–39 in) tall, spreading by offsets. The leaves are thick and fleshy, green to grey-green, with some varieties showing white flecks on the upper and lower stem surfaces. The margin of the leaf is serrated and has small white teeth. The flowers are produced in summer on a spike up to 90 cm (35 in) tall, each flower pendulous, with a yellow tubular corolla 2–3 cm (0.8–1.2 in) long. Like other Aloe species, Aloe vera forms arbuscular mycorrhiza, a symbiosis that allows the plant better access to mineral nutrients in soil

 

The species is frequently cited as being used in herbal medicine. Many scientific studies of the use of aloe vera have been undertaken, some of them conflicting. Despite these limitations, there is some preliminary evidence that Aloe vera extracts may be useful in the treatment of diabetes and elevated blood lipids in humans. These positive effects are thought to be due to the presence of compounds such as polysaccharides, mannans, anthraquinones and lectins.

.Benefits

• Help treat diabetes

• Help treat elevated blood lipids

•Help skin care (Moisturizing and smoothing the skin and anti-irritant)

•Help treat wounds.

Aloe veraextracts have antibacterial and antifungal activities.

 

Mechanism

Biologically active compounds

Aloe veraleaves contain a range of biologically active compounds, the best studied being acetylated mannans, polymannans, anthraquinone C-glycosides, anthrones and anthraquinones and various lectins.

Aloe veraextracts may be useful in the treatment of diabetes and elevated blood lipids in humans. These positive effects are thought to be due to the presence of compounds such as polysaccharides, mannans, anthraquinones (Aloin and etc.) and lectins.

Aloin is an anthraquinone glycoside, meaning that its anthraquinone skeleton has been modified by the addition of a sugar molecule. Anthraquinones are a common family of naturally occurring yellow, orange, and red pigments of which many have cathartic properties, attributes shared by aloin. Aloin is related to aloe emodin, which lacks a sugar group but shares aloin's biological properties.

Aloin does not have good stability in aqueous solutions. Products derived from the gel of the aloe plant do not contain appreciable amounts of aloin, and have not been proven effective for any disease or condition when taken orally.

Safety

Aloe gel (inner-leaf transparent gel, without Aloin) is safe for use as dietary supplements and food, but the substance(outer-leaf green/yellow fluid), with Aloin is controlled.

Once ingested, aloin increases peristaltic contractions in the colon, which induces bowel movements. Aloin also prevents the colon from re-absorbing water from the gastrointestinal tract, which leads to softer stools. This effect is caused by aloin's opening of chloride channels of the colonic membrane. In higher doses, these effects may lead to electrolyte imbalance, diarrhea, and abdominal pain, which are common side-effects of the drug.Because aloin can potentially cause uterine contractions; pregnant women should avoid ingesting aloe products.

In a study on consumption of aloe in rats and tilapia (with no separation of gel from aloin), significant negative health effects were found, including normocytic normochromic anaemia (low red blood cell count, but normal cells), hypoproteinaemia, and high AST levels. As many studies involving aloe gel (without aloin) have not observed these negative effects, it is possible that the negative effects could in large part be due to aloin.

Plant-derived remedies containing aloin and other anthraquinones have been used as traditional medicines since antiquity, but harsh side effects make aloin generally unsuitable for household or daily use. In 2002, the US FDA mandated that manufacturers reformulate or stop manufacturing over-the-counter products containing aloe because the agency did not receive necessary safety data. The substance is still allowed in dietary supplements [21 U.S.C. 321 (ff)(1)] and is allowed for use in foods (primarily alcoholic beverages).

Dosage and Uses

 

Dosage

• The typical dose for extract with aloin is 300-900mg per day (usually in 2-3 doses throughout the day), the gel without aloin is not limited.
• Consult physicians for different condition specifics.

Uses

                       

Certain moisturizers contain Aloe vera.       Certain Aloe vera juice for ingestion.

Distinction between Aloin and Gel (Without or less Aloin) of the plant

Aloe vera leaves when cut exude two fluids, with differing effects and properties. The yellow/green sap predominantly exuded wherever the green surface of the leaf is cut is an irritant. This contains the latex-like compound, aloin. On the other hand, the transparent fluid exuded by the inner leaf wherever it is cut or crushed, is soothing and said to promote healing.

For successful use of the plant, it is important to ensure that any use employs the appropriate part or parts to suit the purpose.

It is also important to understand and look for this distinction in evaluating any attempt at scientific study of the plant's medical properties. Any study which does not specify which parts of the plant were used is likely to confuse the issue, rather than to clarify. Any product which does not distinguish these may contain a mixture of both, and therefore would be likely to have compromised usefulness for most purposes where Aloe vera is commonly used.

Medicinal uses

Scientific evidence for the cosmetic and therapeutic effectiveness of Aloe vera is limited and when present is typically contradictory. Despite this, the cosmetic and alternative medicine industries regularly make claims regarding the soothing, moisturising and healing properties of Aloe vera, especially via Internet advertising.Aloe vera gel is used as an ingredient in commercially available lotion, yogurt, beverages and some desserts. Aloe vera juice is used for consumption and relief of digestive issues such as heartburn and irritable bowel syndrome. It is common practice for cosmetic companies to add sap or other derivatives from Aloe vera to products such as makeup, tissues, moisturizers, soaps, sunscreens, incense, razors and shampoos. It has also been suggested that biofuels could be obtained from Aloe vera seeds. Other uses for extracts of Aloe vera include the dilution of semen for the artificial fertilization of sheep, use as fresh food preservative, and use in water conservation in small farms.

Aloe verahas a long association with herbal medicine, although it is not known when its medical applications were first discovered. Early records of Aloe vera use appear in the Ebers Papyrus from 16th century BCE,in both Dioscorides' De Materia Medica and Pliny the Elder's Natural History written in the mid-first century CE along with the Juliana Anicia Codex produced in 512 CE.Aloe vera is non-toxic, with no known side effects, provided the aloin has been removed by processing. Taking Aloe vera that contains aloin in excess amounts has been associated with various side effects. However, the species is used widely in the traditional herbal medicine of China, Japan, Russia, South Africa, the United States, Jamaica and India.

Aloe verais alleged to be effective in treatment of wounds. Evidence on the effects of Aloe vera sap on wound healing, however, is limited and contradictory. Some studies, for example, show that Aloe vera promotes the rates of healing, while in contrast, other studies show that wounds to which Aloe vera gel was applied were significantly slower to heal than those treated with conventional medical preparations. A more recent review (2007) concludes that the cumulative evidence supports the use of Aloe vera for the healing of first to second degree burns. In addition to topical use in wound or burn healing, internal intake of Aloe vera has been linked with improved blood glucose levels in diabetics, and with lower blood lipids in hyperlipidaemic patients, but also with acute hepatitis (liver disease).In other diseases, preliminary studies have suggested oral Aloe vera gel may reduce symptoms and inflammation in patients with ulcerative colitis. Compounds extracted from Aloe vera have been used as an immunostimulant that aids in fighting cancers in cats and dogs; however, this treatment has not been scientifically tested in humans. The injection of Aloe vera extracts to treat cancer has resulted in the deaths of several patients.

Topical application of Aloe vera may be effective for genital herpes and psoriasis. However, it is not effective for the prevention of radiation-induced injuries. Although anecdotally useful, it has not been proven to offer protection from sunburn or suntan. In a double-blind clinical trial the group using an Aloe vera containing dentifrice and the group using a fluoridated dentifrice both demonstrated a statistically significant reduction of gingivitis and plaque.

Aloe veraextracts have antibacterial and antifungal activities. Aloe vera extracts have been shown to inhibit the growth of fungi that cause tinea; however, evidence for control beneath human skin remains to be established. For its anti-fungal properties, Aloe vera is used as a fish tank water conditioner. For bacteria, inner-leaf gel from Aloe vera was shown to inhibit growth of Streptococcus and Shigella species in vitro. In contrast, Aloe vera extracts failed to show antibiotic properties against Xanthomonas species.

Commodity uses

Aloe vera is now widely used on face tissues, where it is promoted as a moisturiser and/or anti-irritant to reduce chafing of the nose of users who suffer hay-fever or cold.

Historical uses

Aloin was the common ingredient in OTC laxative products in the United States prior to 2003, when the FDA ruled that aloin was a class III ingredient, therefore banning its use.It should be noted that processed aloe that contains aloin is used primarily as a laxative, whereas processed aloe vera juice that does not contain significant amounts of aloin is used as a digestive healer. Manufacturers commonly remove aloin in processing due to the FDA ruling.
