Aloe

Current Uses

Botanical Family: Asphodelaceae

Of the hundreds of species in the genus Aloe, the most well known is undoubtedly Aloe vera. This plant produces two substances: a yellow-green latex that has a bitter taste, and a clear gel known for its skin soothing abilities. It is primarily prized for the cooling, slimy gel within its leaves, as Aloe vera has been widely used in cosmetics and topical application for centuries. The gel is a soothing and welcome first aid for skin burns where its relieving effect is immediate.

The gel is also taken internally to relieve constipation and inflammation, but caution is urged due to its laxative effects. It has a grassy, pleasantly bitter taste and soft, crunchy texture. Both TCM and Ayurveda use Aloe vera in traditional medicine preparations.

The unique bitter flavor found in the liquid latex is used in the production of various beverages, including amari.

In addition to vera, the ferox and arborescens species of Aloe are used medicinally.

Precautions

The yellowish-green latex contains anthraquinones, most notably barbaloin and emodin, which give Aloe its purgative and laxative effects. Aloe should always be consumed with caution and only in small, recommended quantities. It is recommended that pregnant and nursing mothers avoid consuming Aloe.

Substitutions

While unequaled in its unique composition, some substitutions for Aloe vera include cucumber, chamomile, and calendula for cooling, soothing properties without the bitterness. Other varieties of Aloe include Aloe ferox and Aloe perryi, which are more difficult to source, but could be ideal substitutes. Like Aloe vera, precautions should be observed in particular with internal consumption.

History

Aloe vera is mentioned in the Papyrus Ebers circa 1550 BC and was prized by the ancient Egyptians as the “Plant of Immortality.” Historical legend purports that Alexander the Great sent his army from Greece to obtain the plant from  Socotra, an island off the coast of Yemen.
