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."
