Aloe
Commercial products: Choosing effective
Aloe Vera products can be challenging. Once a leaf is cut, enzymes
start to break down some of the long chain sugars which make Aloe
Vera gel an effective healing product, so it is important for the
plant to have been properly handled and stabilized. Ask for help in
selecting a reputable company to buy from. When shopping for a
product to use for topical healing, look for Aloe Vera to be one of
the first products listed to ensure that it is not too dilute to be
efficacious. Commercial, stabilized gel products may not work as well
as the fresh gel, but cold processing is thought to best retain the
beneficial properties. The FDA does not regulate labeling of Aloe
Vera products.
Aloe Vera juice is most often the form of the gel that
is used internally. At least half of the juice should be Aloe Vera
gel. If laxative properties are not desired, be sure that the juice
does not contain latex. A product that is made from the whole leaf
does not necessarily contain anthraquinones from the latex layer, as
those are water-soluble and can be separated out during processing.
Capsules and tinctures of the gel are also available. Oral forms of
the latex extract are generally capsules, as it is extremely bitter.
Growing at home: For common topical use,
keeping a plant at home is one of the easiest ways to get the
freshest and most concentrated gel. It is easy to cultivate,
requiring only good drainage, mild temperatures, and occasional
watering. Bring the plant inside if outside temperatures are less
than 40°F (4.4°C). It will tolerate either full or partial
sunlight, but will require more frequent watering in full sun. Water
it only when the soil has become dry. To use the gel, break off a
leaf and cut it lengthwise to expose the inner layer. Scoop the gel
out and apply generously to the area needing treatment. Discard
whatever gel is not used immediately, as it will degenerate quickly.
The inner portion of the leaf may also be applied directly to a skin
injury, and bound to it.
Precautions: Gel is generally safe for
topical use, but it is best to apply it to a small area first to test
for possible allergic reaction. Stinging and generalized dermatitis
may result in individuals who are sensitive to it. The vast majority
of the warnings apply only to products containing anthraquinones,
such as aloin and barbaloin (as well as the numerous others), which
are found in the latex layer of the plant. Aloe Vera latex should not
be used internally by women who are pregnant or lactating, or by
children. This product can cause abortion or stimulate menstruation.
It may pass into the milk of breast feeding mothers. People who have
abnormal kidney function, heart disease, or gastrointestinal diseases
are best advised to avoid any product containing latex or
anthraquinones. Prolonged, internal use in high doses may produce
tolerance so that more is required to obtain the laxative effect. Be
aware of the possibility that any product for internal use that is
supposed to contain only the gel portion can become contaminated by
the anthraquinones of the latex layer. For this reason, people who
have a contraindication for using latex should use caution when
taking a gel product internally.
Side effects: Internal use of Aloe Vera
latex may turn the urine red, and may also cause abdominal pain or
cramps when products containing anthraquinones are consumed.
Interactions: Chronic internal use of
products containing latex may increase the likelihood of potassium
loss when used concomitantly with diuretics or corticosteroids. It
may possibly compound the risk of toxicity when used with cardiac
glycosides (both prescription and herbal types) and antiarrhythmic
drugs. Absorption of other oral medications can be decreased. Latex
should not be used with other laxative herbs, which may also lead to
excessive potassium loss.
Internal use of gel can cause changes in blood sugar,
so diabetics should monitor blood glucose levels during use,
particularly if insulin or other pharmaceuticals are being used to
control hyperglycemia.
Topical Aloe Vera may enhance the effect of topical
corticosteroids and allow a reduction in the amount of the steroid
being used.
