Originally from Africa, the gel from inside the fleshy leaves of the aloe
vera plant has been used since the 4th century BC to treat minor burns,
intestinal problems like stomach ulcers, and to help speed wound healing.
Scientific studies have shown that a complex carbohydrate in aloe vera,
acemannan, combines antiviral properties, antibacterial action and also
stimulates the immune system.
Gel-based creams are effective when applied externally to skin burns and
wounds.
Aloe vera gel-based drinks have also proved useful for people suffering
mouth ulcers and peptic ulcers (unless they are drug-or stress-induced).
Aloes and aloe gel are often confused with each other. Aloes, which are
obtained by evaporating water from the bitter yellow juice drained from
the leaves, contains anthraquinones - a strong purgative often used as a
laxative. Aloe vera gel, on the other hand, is obtained from the jelly-like
tissue in the centre of the leaf, and does not contain any anthraquinones.
For this reason, pregnant women should avoid taking (internally) aloe vera
products that could contain anthraquinones. Externally-applied aloe vera
gel during pregnancy is not believed to cause concern.
Aloe vera can vary in strength, according to its preparation, therefore it
is usually advised to follow the dosing directions given on each product's
packaging.
