Aloe vera has been used in herbal medicine in treating many kinds of disease, including wound, burn healing, minor skin infections, sebaceous cysts, diabetes, and elevated of cholesterol, etc. It is also one of many popular herb studied in scientific ways with some conflicted results.
The Ingredients
The ten main areas of chemical constituents of Aloe vera include: amino acids, anthraquinones, enzymes, minerals, vitamins, lignins, monosaccharide, polysaccharides, salicylic acid, saponins, and sterols.
1. The benefits of Aloe vera against acne vulgaris
There are many types of skin diseases in this world, the most common one is acne. Most people know acne is caused by dirt in oily skin pores, but little is known that acne is also caused by the system of toxins in the body. If our liver and kidney can not cleanse all toxins in the body, then our skin become the third source for cleansing the remainder of toxins.
The benefits
Ance vulgaris, one of skin diseases with areas of scaly red skin with seborrhea, blackheads and whiteheads. Aloe vera one of many herbs has been studied and researched in pharmaceutical world, because of the common problem to the young ages and commercial profits. The study to compare the efficacy and safety of the combination of tretinoin (TR) cream (0.05%) and Aloe vera topical gel (50%) with TR and vehicle, has been well tolerated and significantly more effective than TR and vehicle for the treatment of mild to moderate acne vulgaris and with less side effects. Other researchers in the observation of traditional medicines of many cultures used to treat skin diseases, indicated that certain ingredients, including aloe vera, have been identified in the treatment of psoriasis and atopic dermatitis,

The effects of Aloe vera in Irritable bowel syndrome
Aloe vera (AV) has long been suggested by herbal medicine in treating irritable bowel syndrome (IBS) symptoms. In the comparison of the effectiveness of a mixture of Aloe vera (AV) and Matricaria recutita (German chamomile, GC) in treating Irritable bowel syndrome, GC inhibited only small bowel transit while the AV/GC mixture delayed gastric emptying at the doses of 150 and 300 mg/kg. The AV/GC mixture also reduced colonic transit and small bowel transit at the dose of 150 mg/kg. In other Randomised double-blind placebo-controlled trial of to test the effects of aloe vera for irritable bowel syndrome, there was no evidence that AV benefits patients with IBS and superior to placebo in improving quality of life proven Irritable Bowel Syndrome patients., but in 49 completed the protocol to 1 month and 41 to 3 months. Eleven of thirty-one (35%) AV patients, and 6 of 27 (22%) placebo patients responded at 1 month (p = 0.763). Diarrhoea predominant patients showed a trend towards a response to treatment at 1 month (10/23 V 2/14, p = 0.07).

8. Aloe Vera and Immunity
The immune system is the set of cells and their activity against antigens or infectious agents that comprises of the body's defense system against diseases. The immune system does a great job of keeping people healthy and preventing infections. Beside foods and nutritional supplements, herbs also play a important role in helping the immune system defend against viruses and bacteria attacks.
The benefits
Aloe Vera is best known for it anti-inflammatory effects, in the study to determine the effect of the inner gel on bacterial-induced pro-inflammatory cytokine production, Aloe vera suppresses bacterial-induced pro-inflammatory cytokines from human immune cells. In the pharmacological study of Aloe arborescens Miller leaf components, The Aloe extract (1.2 mg ml(-1)) acted as a powerful immune stimulant in LPS- or poly I:C-activated SAF-1 cells, inducing a synergic effect on interconnected genes that are expected to be involved in different aspects of the immune responses. Aloe polymannose, a chemical compound found in Aloe Vera, also enhances the cognitive and immune functioning in patients of Alzheimer's disease by decreasing tumor necrosis factor-α, vascular endothelial growth factor, and interleukins-2 and-4

9. Aloe Vera and Type II Diabetes
Diabetes is defined as a condition caused by insufficient insulin entering the bloodstream to regulate the glucose. It is either caused by cells in pancreas dying off or receptor sites clogged up by fat and cholesterol. In some cases, diabetes is also caused by allergic reactions of cells in the immune system.
The benefits
Many herbs have been proven in studies to be effective in treating type II diabetes, including Aloe vera. As a popular herbal remedy in the United Kingdom, oral administration of aloe vera might be a useful adjunct for lowering blood glucose in diabetic patients as well as for reducing blood lipid levels in patients with hyperlipidaemia. In other study of Aloe vera gel in a mouse model of non-insulin-dependent diabetes mellitus, Oral administration of PAG for 8 weeks was found to reduce circulating blood glucose concentrations to a normal level in these DIO mice. Its leaf is also found to be useful in treating diabetes, as study said A. vera leaf pulp extract showed hypoglycaemic activity on type I (IDDM) and type II (NIDDM) diabetic rats, the effectiveness being enhanced for type II diabetes in comparison with glibenclamide. On the contrary, A. vera leaf gel extract showed hyperglycaemic activity on NIDDM rats.

10. Aloe Vera and Cancers
Cancer is a class of diseases in which a group of cells growing and multiplying disordered and uncontrollable way in our body, have become progressively worse and damaged other healthy tissues, sometimes spreads to other organs in the body via lymph or blood and results may be in death.
The Benefits
Aloe-Emodi, a chemical compound found in Aloe vera, specifically suppress breast cancer cell proliferation by targeting ER α protein stability through distinct mechanisms and may be used as a possible application of anthraquinones in preventing or treating breast cancer in the future. Also in other study, Aloe-Emodi is considered as a potential value for the treatment of gastric cancer and cervical cancer because of its mechanisms are by means of cell cycle interruption and induce differentiation and suppressed the expression of PKCalpha and c-myc. Radiotherapy are most often used to treat head and neck cancer patients. Ina study of Aloe Vera, Dr. Ahmadi A. found that oral Aloe vera mouthwash may not only prevent radiation-induced mucositis, but also may reduce oral candidiasis of patients undergoing head and neck radiotherapy due to its antifungal and immunomodulatory properties

11. Aloe Vera and Skin Aging
A free radical is any atom or molecule that has a single unpaired electron in an outer shell and highly reactive to react with other cell, which in turn, causes oxidative damage to the enzymes, other protein, unsaturated fatty acid, phospho-lipids, DNA and RNA, etc., leading to aging of the organisms, as a result of widespread damage due to set of a chain reaction auto-catalytically after attacking the lipid bilayers of the cell walls. Free radicals oxidative effects can damage to skin and speed up the skin aging process.
The benefits
Aging is a natural process, no one can stop but delay it. Aloe Vera Supplementation has long been promote by cosmetic industrial for reducing the progress of skin aging. The study of 30 healthy female subjects over the age of 45 received 2 different doses (low-dose: 1,200 mg/d, high-dose: 3,600 mg/d) of aloe vera gel supplementation for 90 days. to determine the effect of aloe gel on the clinical signs and biochemical changes of aging skin, researchers found that the facial wrinkles improved significantly (p<0.05) in both groups, and facial elasticity improved in the lower-dose group. In the photoprotected skin, the type I procollagen mRNA levels were increased in both groups, albeit without significance; the MMP-1 mRNA levels were significantly decreased in the higher-dose group. In UVB-Induced Skin Photoaging in vitro, aloe shoot extract (AE), which is from the four-month-old shoots of Aloe vera, have a protective effect on UVB-induced skin photoaging in normal human dermal fibroblasts (NHDFs). As a anti-inflammatory agent, aloe vera, havs been identified as beneficial in the treatment of psoriasis and atopic dermatitis.

12. Aloe Vera and Polycystic Ovarian Syndrome
Polycystic Ovarian Syndrome is defined as endocrinologic diseases caused by undeveloped follicles clumping on the ovaries that interferes with the function of the normal ovaries as resulting of enlarged ovaries, leading to hormone imbalance( excessive androgen), resulting in male pattern hair development, acne,irregular period or absence of period, weight gain and effecting fertility. It effects over 5% of women population or 1 in 20 women. According to the study by Desai BN, Maharjan RH, Nampoothiri LP. almost 70% PCOS women have abnormal serum lipid levels (dyslipidemia) and 50% of these women are obese. Several classes of pharmacological agents have been used to manage dyslipidemia. However, studies have shown adverse effects associated with these drugs(1).
The Benefits
Aloe Vera may be a potential herb in treating Polycystic Ovarian Syndrome by enhancing the reductions of plasma triglyceride and LDL cholesterol levels, with an increase in HDL cholesterol or by restoring the ovarian steroid status. According to the study of PCOS was induced in Charles Foster female rats by oral administration of non-steroidal aromatase inhibitor letrozole (0.5 mg/kg body weight, 21 days), AVG treated PCOS rats exhibited significant reduction in plasma triglyceride and LDL cholesterol levels, with an increase in HDL cholesterol. The gel treatment also caused reversion of abnormal estrous cyclicity, glucose intolerance, and lipid metabolizing enzyme activities, bringing them to normal. Other study also indicated that Aloe vera gel formulation exerts a protective effect in against the PCOS phenotype by restoring the ovarian steroid status, and altering key steroidogenic activity. This can be attributed to phyto-components present in the extract.
Dr.Pérez YY and the research team in the study of Effect of a polyphenol-rich extract from Aloe vera gel on experimentally induced insulin resistance in mice also indicated that decreasing significantly both body weight (p < 0.008) and blood glucose levels of Aloe, calculated using the homeostasis model assessment for insulin resistance (HOMA-IR) formula by the polyphenol-rich extract from Aloe vera.
Also in the confirmation of aboce result, study of Aloe vera leaves on blood glucose level in type I and type II diabetic rat models, vera leaf pulp extract showed hypoglycaemic activity on IDDM and NIDDM rats, the effectiveness being enhanced for type II diabetes in comparison with glibenclamide. On the contrary, A. vera leaf gel extract showed hyperglycaemic activity on NIDDM rats. It may therefore be concluded that the pulps of Aloe vera leaves devoid of the gel could be useful in the treatment of non-insulin dependent diabetes mellitus. Where non-diabetic (ND), type I (IDDM) and type II (NIDDM) diabetic rats.

16. Aloe vera and lung cancer
Lung cancer is defined as a condition of the abnormal growth of
the cells in the lung's tissue. Most common form of primary lung
cancers are derived from epithelial cells. In Us, Lung cancer is the
leading cause of cancer deaths, causing 158,683 people deaths,
including 88,329 men and 70,354 women, according to 2007 statistic.
The main areas of chemical constituents of Aloe vera include: Aloe-Emodin, amino acids, anthraquinones, enzymes, minerals, vitamins, lignins, monosaccharide, polysaccharides, salicylic acid, saponins, and sterols.
The benefits
Aloe-emodin has been studied extensively through our scientific community for their effects against cancer including the study of induced apoptosis in lung carcinoma cell lines CH27 (human lung squamous carcinoma cell) by breaking of DNA strands (DNA ladders and sub-G(1) formation) and regulating of the expression of Bcl-2 family proteins (a suppressor of apoptosis). In the study of the effects of aloe-emodin-induced cell death in the human lung nonsmall cell carcinoma cell line H460, aloe-emodin involved the regulating apoptotic cell death through the a class of mitogen-activated protein kinases(p38). These results suggested that aloe-amodin found in ALOE VERA may be a potential agent for preventing and treating lung cancer.
