Sources
The different aloes from the different places such
as from Caribbia, South Africa or west India contain essentially
the same ingredients and produce the similar effects. Aloe is the
juice collected from the cut leaves by evaporating process. The
juice is then heated until all the liquid is driven off, leaving
large, translucent blocks of the active in gradients. The common
used cape Aloe comes mainly from South Africa. Aloe Vera gel of
the Aloe Barbadensis is made from the central part of the aloe leaf
but not from the juice.
Burn, especially radiation burns. Fresh wound application.
Aloe is used to treat headache, dizziness, insomnia, constipation,
or inset bite.
Effects
1) Purgative: Aloe, contains chemical molecules called anthraquinones
(AQ), like other members of the Lily family (including senna, cascara
and rhubarb) does. When still in the plant, these molecules are
bound to glucose molecules tightly, which makes them inactive and
prevents them from being absorbed in the gut of the body. When the
AQ-glucose complex is ingested into the gut and gets into the large
intestine, bacteria in the large intestine break dow
n the sugar molecule, allowing free AQ to react with cells on the
wall of the large intestine. AQ increases the transportation of
water and salts from the cells into the intestinal tract. The large
intestine, colon, was stimulated to contract by increasing of contained
volume inside the lumen. A result of increasing bowel movement usually
occur six to ten hours after aloe is taken.
2) Promote wound healing: Aloe has been used for wound
of boil burn, radiation burns and other skin irritations. Even though
the evidence showed that the Aloe Vera is very widely effect of
using in treatment of assortment of skin diseases, controlled studies
testing its effectiveness in treating these conditions have produced
inconclusive results. Some studies have shown that results with
Aloe Vera are no better than with placebo. Many believe that Aloe
provides a barrier over the wound to speed the wound healing process.
On the other hand, there are studies showing that Aloe Vera really
does accelerate the wound healing process itself.
3) Others: There is some evidence shown Aloe can increase immunity
and accelerate wound healing and also appears to have anti-bacterial
and antiviral effects as well. In test tubes, Aloes are good antioxidants,
made them to be suggested to may have a role in preventing heart
disease and aging. Unfortunately, these observations have not been
validated in human beings. Laboratory evidence also demonstrated
Aloe speed up the metabolic rate of alcohol, if the studies could
be confirmed, Aloe might be proven to be an effective remedy for
hangover.
Concerns
Small amount of the active ingredient of Aloe can
be absorbed from the large intestine that may appear in mother's
milk. Aloe can cause intestinal cramping accompanied with its purgative
effect in some cases. These give a consideration of not taken Aloe
by pregnant woman or nursing mother and person who has marked hemorrhoid.
The color of urine could turn brown or red after taken Aloe, the
appearance of color related much to the acidity of the urine, is
not a sign of blood presence in the urine.
Precautions
Long term use of Aloe as a laxative can deplete
the body of potassium, and low levels of potassium can cause dangerous
irregularities of heart beats. (not just aloe, but also senna) cause
an apparently benign condition called melanosis coli. Brownish pigment
accumulates in the wall of the large intestine, called melanosis
coli, can be caused by chronic Anthraquinone-containing laxatives
using. Although it seems to do no harm but a recommendation of not
to use the lily family laxatives for more than 10 days. Because
danthrone can cause tumors in laboratory animals, preparations made
from danthrone have been withdrawn from the market. Similar tumors
have not been reported after using the natural products (aloe, senna,
cascara, rhubarb), but most physicians still not advise their chronic
use.
Dosage
Suggestive dose of Aloe is 50 to 200 milligrams
taken at bedtime. Since it breaks down very rapidly, especially
taken with liquid form, the effective amount in the body is not
exactly estimated. Neither the U.S. nor the European governments
have set limits on the amount that can be added to food or beverages
yet. Consumers should closely read carefully the labels of all products.
Summary
Aloe-based products are effective laxatives and
use also for skin disease. Fresh aloe good for wound healing particularly
after burn. Aloe can give some adverse effect such as abdominal
cramping, low blood potassium, or color-urine. Research showed it
also has antioxidant or carcinogen effects, these have to confirm
in humans by more studies. Long term use is not advised.
Interesting Facts
The medicinal properties of aloe have been recognized
for thousands of years. However, large scale commercial production
of aloe did not begin until the late 1600s, when traders first brought
Barbados aloe to London. In the 1860s, two Scottish physicians isolated
aloe's active ingredient, called it Aloin (now known as babrolin),
and began using it to treat constipation. Other than the formal
use as a purgative, many other illnesses had been tried to apply
by peoples. Such as hypertension, gastritis, peptic ulcer, gout,
joint pain, neuritis, headache, even asthma had been used in Asia
with good help. But none of them has been proven but scientific
reports. Plenty products of shampoo or skin lotion are added with
Aloe that you can find from markets. These are based on its repairing
action to skin or small wounds as well as anti-bacterial function.
If it can rejuvenate the skin is still doubtful. The appearance
of Aloe is similar to Cactus, and should be plant in warm places.
Its flower usually is orange in color. Other than its treating usage
it also is good to plant in the garden or inside the house for decoration.
