The Potted Physician, 13 Ways Aloe Vera Can Help You:
Known to herbalists and medical
folklorists for centuries as the "medical plant" or "the potted physician", this
cactus-like plant with green dagger-shaped leaves filled with a clear, viscous
gel was brought from Africa to North America in the sixteenth century.
But long before this, aloe,
whose name means "shining bitter substance," was widely regarded as a master
healing plant. The ancient Egyptians referred to aloe as the "plant of
immortality" and included it among the funerary gifts buried with the pharaohs.
In recent decades, medical research has confirmed and extended many of the
health claims for the shining bitter substance (used topically or consumed as a
liquid) that is the heart of aloe. Here is a brief review of its merits.
Aloe Leaf Helps Heal Wounds:
The bulk of the aloe leaf is
filled with gel, 96% water with the other 4% containing 75 known substances.
Applied to wounds, aloe gel is a mild anesthetic, relieving itching, swelling,
and pain: it also is antibacterial and ant fungal, increases blood flow to
wounded areas, and stimulates fibroblasts, the skin cells responsible for wound
healing.
An animal-based study in the
Journal of the American Podiatric Medical Association found that both oral and
topical aloe preparations speed wound healing. Animals were given either aloe
(100mg/kg body weight) in their drinking water for two months or 25% aloe Vera
cream applied directly to wounds for six days.
Aloe had positive effects in
both cases. The size of wounds decreased 62% in the animals taking oral aloe
compared to a 51% in the control group. Topical aloe produced a 51% decrease in
wound size compared to a 33% in the control group.
Aloe Supports Surgical Recovery:
Aloe decreases surgical
recovery time, according to a report in the Journal of Dermatologic Surgery and
Oncology. Eighteen acne patients underwent facial dermabrasion surgery, in which
lesions are scraped away. Dressings were applied to their faces, with half of
each person's face receiving the standard dressing coated with surgical gel, and
the other half with aloe added to this dressing. The half of the face treated
with aloe healed approximately 72 hours faster than the other side.
Dermatologist James Fulton,
M.D., of Newport Beach, California, principal author of the report, uses topical
aloe in his practice to speed wound healing. "Any wound we treat, whether it's
suturing a cut or removing a skin cancer, heals better with aloe Vera on it," he
states.
Soothes Burns:
In a study in the Journal of
the Medical Association of Thailand, 27 patients with moderate burn wounds were
treated with a gauze coated in either aloe gel or Vaseline'~ (petroleum jelly).
The burns healed more quickly in the aloe group, with an average healing time of
12 days compared to 18 days for the group using Vaseline.
Minimizes Frostbite Damage:
A study published in the Annals
of Emergency Medicine established that aloe works for frostbite as well.
Researchers gave standard treatments for frostbite (antibiotics, ibuprofen, and
rewarming) to 154 patients with mild to severe frostbite. Of patients who
additionally received aloe Vera cream, 67.9%
healed without any tissue loss
(amputation) compared to 32.7% in the control group. Researchers concluded that
aloe prevented a decrease of blood flow to the frozen tissues, a common cause of
tissue loss in frostbite.
Screens Out Radiation:
Aloe protects against skin
damage from X rays, according to researchers at Hoshi University in Japan
publishing in the journal Yakugaku Zasshi. They found that aloe was an effective
antioxidant, mopping up the free radicals caused by radiation, and that it
protected two of the body's healing substances, superoxide dismutase (an
antioxidant enzyme) and glutathione (an amino acid which stimulates the immune
system).
Heals Psoriasis Lesions:
In a double-blind,
placebo-controlled study published in Tropical Medicine and International
Health, 60 patients with chronic psoriasis were given a 0.5% aloe Vera extract
in a mineral oil cream. The ointment was applied three times daily for five
consecutive days (15 applications total per week) for four weeks.
When patients were checked
after eight months, far more psoriasis skin lesions had healed in the aloe group
(82.8%) than in the placebo group (7.7%). Further, 83.3% of the aloe group were
considered cured of their psoriasis compared to only 6.6% of the placebo group.
Eases Intestinal Problems:
Aloe Vera juice can be
effective for treating inflammatory bowel disease, according to a study in the
Journal of Alternative Medicine. Ten patients were given two ounces of aloe
juice, three times daily, for seven days. After one week, all patients were
cured of diarrhea, four had improved bowel regularity, and three reported
increased energy.
Researchers concluded that aloe
was able to rebalance the intestines by "regulating gastrointestinal pH while
improving gastrointestinal motility, increasing stool specific gravity, and
reducing populations of certain fecal microorganisms, including yeast." Other
studies have shown that aloe Vera juice helps to detoxify the bowel, neutralize
stomach acidity, and relieve constipation and gastric ulcers.
Reduces Blood Sugar in
Diabetes:
Aloe reduced the blood sugar
levels in diabetics, as reported in Hormone Research. Five patients with adult
(non-insulin-dependent) diabetes were given 1/2 teaspoon of aloe extract daily
for up to 14 weeks. Blood sugar levels were reduced in all patients by an
average of 45%, with no change in their total weight.
Reduces Arthritic Swelling:
Aloe can help prevent arthritis
and reduce the inflammation in joints already affected by arthritis, according
to the Journal of the American Podiatric Medical Association. Aloe can also
inhibit the autoimmune reaction associated with certain forms of arthritis, in
which the body attacks its own tissues.
Animals were injected with a
bacterium to cause arthritic symptoms, namely inflammation and swelling. To
determine if it could prevent arthritis, aloe (150mg/kg body weight) was
injected under the skin daily for 13 days. Physical measurements were taken
daily to determine the amount of swelling and inflammation.
Several compounds from aloe
showed ant arthritic activity, according to the researchers. One organic acid in
aloe reduced inflammation by 79.7% and suppressed the autoimmune response by
42.4%. Another aloe compound (anthraquinone) reduced inflammation by 67.3% but
had no effect on the autoimmune response.
Curtailing HIV Infection:
An extract of mannose, one of
the sugars in aloe, can inhibit HIV-1 (the virus associated with AIDS). In a
1991 study in Molecular Biotherapy, HIV-1 cells were treated in vitro (outside
the body) with a mannose extract. Aloe slowed virus reproduction by as much as
30%, reduced viral load (total amount of the virus), suppressed the spread of
the virus from infected cells, and increased the viability (chance of survival)
of infected cells.
Nutritional Support for HIV
Patients:
Aloe Vera juice proved to be an
effective part of a nutritional support program for HIV+ patients according to
the Journal of Advancement in
Medicine. For four months, 29
patients were given 100% pure aloe Vera juice (five ounces, four times daily)
along with an essential fatty acid supplement and another supplement containing
vitamins, minerals, and amino acids. Patients were told to continue with their
normal diet and not to take other supplements.
After 90 days, all of the
patients had fewer occurrences of opportunistic infections, thrush, fatigue, and
diarrhea, as well as increased white blood cell counts (meaning their immune
systems were responding positively). Their assessment of overall quality of
health also improved. In 25% of the patients, aloe apparently knocked out the
virus's ability to reproduce. Researchers found that aloe (the mannose extract
and perhaps other compounds) stimulates the body's immune system, particularly
T4 helper cells, white blood cells that activate the immune response to
infection.
Stimulates Immune Response
Against Cancer:
Aloe may help prolong survival
time and stimulate the immune system of cancer patients, according to recent
research. In a 1994 study in the Japanese medical journal Yakhak Hoeji, mice
with cancerous tumors were given aloe orally for 14 days. While the aloe did not
suppress tumor growth, the average life span of the mice was prolonged by 22%
for those given 50mg aloe/kg body weight and by 32% for those given 100mg/kg
daily. A simultaneous experiment on human cancer cells (outside the body) found
that high doses of aloe significantly suppressed the growth of these cancer
cells.
Researchers writing in Cancer
Immunology and Immunotherapy found that a compound (lectin) from aloe, when
injected directly into tumors, activated the immune system to attack the cancer.
Killer T cells, white blood cells that bind to invading cells and destroy them,
began to attack the tumor cells injected with lectin.
Aloe turns on the immune system
by activating macrophages (white blood cells which "swallow" antigens), causing
the release of immune-activating (and anticancer) substances such as interferons,
interleukines, and tumor necrosis factor. In addition, aloe promotes the growth
of normal (non-cancerous) cells, researchers said.
Benefits Lung Cancer:
Aloe's protective effect was
confirmed in a study of 673 lung cancer patients in Okinawa, Japan, published in
the Japanese Journal of Cancer Research. This survey looked at the connection
between smoking, comparative amounts of 17 plant foods in the diet, and the
occurrence of lung cancer over a five-year period.
Aloe was the only one of the
plant foods that was protective against cancer. "The results of plant
epidemiology suggests that aloe prevents human pulmonary carcinogenesis ,"
stated the researchers. Further, aloe is "widely preventive or suppressive
against various human cancers."
