Traditionally Uses of Aloe Vera
Traditionally, aloe was used topically to heal wounds and for various skin conditions, and orally as a laxative. Today,
people take aloe orally as they are believed that Aloe Vera benefits various conditions, including diabetes, asthma,
epilepsy, and osteoarthritis. People use aloe topically for osteoarthritis, burns, sunburns, and psoriasis. Aloe vera benefits
have been advertised and promoted. Aloe vera gel can be found in hundreds of skin products, including lotions and
sunblocks. FDA has approved aloe vera as a natural food flavoring.

Aloe leaves contain a clear gel that is often used as a topical ointment. The green part of the leaf that surrounds the gel
can be used to produce a juice (i.e. Aloe Vera Juice) or a dried substance (called latex) that is taken by mouth. Aloe latex
may benefit people suffered from constipation as it contains strong laxative compounds. While, topical aloe gel may benefit
patients suffered from burns and abrasions.

Aloe Vera Benefits - on irritable bowel syndrome and gastric ulcer
Aloe vera may have benefits on patients suffered from irritable bowel syndrome (IBS). However, researchers from UK could
not find any evidence that Aloe vera benefits patients with IBS in a recent study. [1]

A study has shown that Aloe vera may have gastric acid anti-secretory activity and may protect the gastric mucosa at low
concentrations against injurious agents. [16] While another study of rats shows that Aloe vera treatment can reduce
leukocyte adherence and TNF-alpha level, elevate IL-10 level and promote gastric ulcer healing. [3] Thus, Aloe Vera may
have benefits of gastric protection.

Aloe vera benefits - antioxidative activities, on diabetes, cholesterol & triglyceride levels
Aloe vera itself contains antioxidants such as APS-1 and dihydrocoumarin derivatives and it also assists the aborption of
some anti-oxidants such as vitamins A and C.  The vitamins last longer in the plasma with the Aloes.  [6-8]

Aloe vera relieves oxdative stress in diabetic rats. Oral administration of ethanolic Aloe vera leaf gel extract for 21 days
resulted in a significant reduction in fasting blood glucose, thiobarbituric acid reactive substances, hydroperoxides and
alpha-tocopherol and significant improvement in ascorbic acid, reduced glutathione and insulin in the plasma of diabetic
rats. In addition, this administration also resulted in a significant reduction in thiobarbituric acid reactive substances,
hydroperoxides, superoxide dismutase, catalase and glutathione peroxidase and significant improvement in reduced
glutathione in the pancreas of STZ-induced diabetic rats when compared with untreated diabetic rats. [12]

Aloe vera may have benefits on diabetes.[14, 17-19] Animal studies have shown that aloe vera leaf gel extract is effective
on restoration of altered fatty acid compositions in the liver and kidney of diabetic rats. In a study, researchers suppled
Aloe vera gel extract at a dose of 300 mg/kg body weight per day to STZ-induced diabetic rats for a period of 21 days.
They observed a significant reduction in fasting blood glucose, hepatic transaminases, plasma and tissue (liver and
kidney) cholesterol, triglycerides, free fatty acids and phospholipids and a significant improvement in plasma insulin in the
rats. [4]

Researchers from India suggest that mineral contents, e.g. Mn, Fe, Cu, Zn, may also contribute to the health benefits of
Aloe vera leaf gel on diabetes. [5, 11] As some of these inorganic elements improve impaired glucose tolerance and
diabetes mellitus management. [5]

Aloe vera benefits - liver functions
An Aloe vera leaf gel extract has been shown to be even more effective than glibenclamide in restoring some liver function
parameters in a study of diabetic rats. [10]

Aloe vera Skin?
Aloe vera may benefit some skin conditions. Some researchers applied Aloe vera on skin diseases, e.g. psoriasis and
showed positive results [15], while some do not. [9]

Aloe Vera Side Effects, Warnings
Side effects of ingestion of low dose of Aloe vera are seldom reported. However, Aloe vera side effects may include
diarrhea, electrolyte imbalance, kidney dysfunction, and conventional drug interactions. [2] A case of hepatitis has also
been reported. [13] Further, side effects of topical uses of Aloe vera may include contact dermatitis, erythema, and
phototoxicity.

Do not use Aloe vera together with other platelet aggregation inhibitors, such as sevoflurane and before or after surgery.   
Compounds contained within Aloe vera can cause a reduction in prostaglandin synthesis, which may inhibit secondary
aggregation of platelets. [13] For details about Aloe Vera Side Effects, please click
