Aloe
Vera is species of succulent plant in the genus Aloe, belonging to the
Family Xanthorrhoeaceae, native to Sudan. It has become very popular for
commercial cultivation due to its health benefits. 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,

2. Aloe Vera and Skin diseases
Skin diseases is defined as a condition of skin damage and classified according to each pathogenic causes of diseases.
The benefits of Aloe Vera against Skin diseases
In the a systematic review of Aloe vera's clinical effectiveness, topical application of
aloe vera
is not an effective preventative for radiation-induced skin injuries,
but might be effective for genital herpes and psoriasis. In support to the
above, study by Feily A, Namazi MR. indicated that Topical application
of
aloe vera is not an effective in
sunburn or suntan protection, but might be effective in treating genital
herpes, psoriasis, human papilloma virus, seborrheic dermatitis,
aphthous stomatitis, xerosis, lichen planus, frostbite, burn, wound
healing and inflammation.

3. Aloe vera and Irritable bowel syndrome
Irritable bowel syndrome is defined as a condition, if a patient is
diagnosed with abdominal pain or
discomfort, bloating, and alteration of bowel
habits at least three times a month for the last 3 months without
preexistence of other disease.
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).

4. Aloe
Vera and psoriasis
Psoriasis
is defined as chronic condition of inflammatory skin disease, affecting
the joins and mostly happens to people who are obese are predisposed to
diabetes and heart disease.
The benefits
Many herbal extracts have been used as topical management of plaque psoriasis, including Aloe vera based on multiple studies. Aloe vera gel is used in alternative medicine over the century for the treatment of skin diseases, including
psoriasis, and recent study showed that ethanolic extract of
Aloe vera
leaf gel also produced a significant increase in relative epidermal
thickness and an overall antipsoriatic activity of high effective rate.
Other in the comparison of comparion to evaluate the efficacy of Topical
aloe vera (AV) and 0.1% triamcinolone acetonide (TA) in mild to moderate plaque
psoriasis, AV cream may be more effective than 0.1% TA cream found to be more effective in reducing the clinical symptoms of
psoriasis. Unfortunately, in diverse dermatologic conditions, even though there are some promising results with the use of
aloe vera, but clinical effectiveness of oral and topical
aloe vera may require further studies, according to the study of Dr. Feily A, and Dr. Namazi MR.

Vera and gingivitis
Gingivitis is defined as a condition of Inflammation of Gum Diseases.
The benefits
Aloe
Vera anti-inflammatory property may be the result of the plant used in treatment of gum diseases. In the sudy of 45 patients who were diagnosed with plaque-induced gingivitis were included, aloe mouth wash is proven to be the most potential in
reduction in gingival inflammation caused by plagues. Other in the the
randomized, controlled, and double-blind study, a total of 148
systemically healthy subjects, showed statistically significant decrease
in PI, MGI, and BI scores after the rinse regimen began in comparison
with the use of chlorhexidine. But Dr. de Oliveira SM, and the research
team in comparison of Aloe vera and fluoridated dentifrice, found that
here was a significant reduction on plaque and gingivitis in both
groups, but no statistically significant difference was observed among
them (p>0.01), Aloe vera did not show any additional effect on plaque
and gingivitis control compared to the fluoridated dentifrice.

6. Aloe
Vera and Gastric Ulcers
Gastric ulcers is defined as a
condition of a localized tissue erosion in the lining
the stomach. as a
result of bacteria Helicobacter pylori (H pylori) in most cases.
The benefits
Some
people with gastric ulcers may be not experience any symptoms at all,
while others may have burning pain, severe nausea, and vomiting. In the comparison of the effects of Aloe vera and sucralfate on gastric microcirculatory changes, cytokine levels and gastric ulcer healing, treatment of Aloe vera found to reduce leukocyte adherence and TNF-alpha level, elevate IL-10 level and promote
gastric ulcer healing. Because of its Anti-inflammatory effects, treatment of A.
vera process the enhancement in leukocyte-endothelium interaction are associated with reduction in TNF-alpha level. Other in the study of acute
gastric mucosal lesions induced by 0.6 M HCl and acid outpu, indicated that
Aloe vera is endowed with
gastric acid anti-secretory activity and could protect the
gastric mucosa at low concentrations against injurious agents. Other component of
Aloe vera, the Polymer fraction
(Avpf;
molecular weight cut-off ≥50 kDa; 150 mg/kg body weight, p.o.), reduce
50% of the mRNA expressions of inducible nitric oxide synthase (iNOS)
and
neuronal nitric oxide synthase (nNOS), according to the study.

7. Aloe
Vera and Wound Healing
Wound healing is the natural process of skin repair after it was damaged
The Benefits
In a systematic review, there are cumulative evidence support that
aloe vera might be an effective interventions used in burn
wound healing for first to second degree burns as the use of aloe vera shortens the
healing time. In acute and chronic wounds, although there are an absence of high quality clinical trial evidence to support the use of
Aloe vera topical agents or
Aloe vera dressings as treatments for acute and chronic wounds, but some studies found the reduction in
healing time with
Aloe vera was noted after haemorrhoidectomy (RR 16.33 days, 95% CI 3.46 to 77.15) and application of
Aloe vera
cream on the surgical site is effective in reducing postoperative pain
both on resting and during defecation. In a study of a herbal gel of
Aloe vera extract containing Carbopol 93, shows a promising effect on the
wound healing process.

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

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.

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

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.

13. Aloe vera and breast cancer
Breast cancer
(
malignant breast neoplasm) is a cancer that starts in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the
lobules (Lobular carcinoma) that
supply the ducts with milk. there is also rare cases that breast cancer
starts in other areas of the breast. In 2010, over 250,000 new cases of
breast cancer were expected to be diagnosed in women in the U.S. alone
and the risk of getting invasive breast cancer during life time of a
women is 1/8.
The benefits
Aloe-Emodin, chemical components found in
Aloe-vera and other herbssuch as rhubarb, have been researched for
treamtns of certain kinds of diseases, including cancers. The efficacy
of the conponents are found to inhibit breast cancer
cell proliferation by downregulating ER α protein levels, thereby
suppressing ER α transcriptional activation. In the study of another
constituent, a natural anthracycline from Aloe plant found to exhibit the cytotoxic activity against two human breast cancer cell lines; without (MCF-7) and with (SKBR-3) erbB-2-topoIIalpha coamplification.
The above finding suggested that Aloe vera chemical constituents may be a potential new medicine to treat breast cancer

Prostate cancer is defined as a condition in which the cells of
prostate has become cancerous, causing abnormal cell growth which
spread to the distant parts of the body. Most prostate cancers are slow
growing and enlarged prostate and prostate cancer may be detected
during the Physical (rectum) exams.
The benefits
Aloe-amodin, an anthraquinone present in aloe latex from the aloe plant has been found to suppress
Breast Cancer
Cell Proliferation through ER α Inhibition. In prostate cancer study, the phytochemical inhibited both proliferation and anchorage-independent
growth of PC3 cells by targeting mTORC2 as mTORC2 which plays an important
role in PC3 androgen refractory prostate cell proliferation and
anchorage-independent growth.

15. Aloe vera and colon cancer
Colon Cancer is defined as a condition of the abnormal proliferation of cells in the colon.
The benefits
Aloe emodin (AE), found in Aloe vera has been suggested to have antiproliferative activity in various
cancer
cell lines in many studies. In the study of coplon cancer, AE
appreciably induced cell death specifically through the induction of
apoptosis and by activating caspases 9/6, depending on caspase-
6. Other study on colon cancer also showed an efficacy of AE as it
suppressed the nuclear translocation and DNA binding of NF-κB, which is
an important transcription factor for controlling MMP-2/9 and VEGF gene
expression.

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 Ingredients
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.
