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.


• 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.



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.


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



• 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.
