Aloe Vera: History and Medicinal Uses

Introduction

IMPORTANT NOTE

Use of topical aloe vera is not associated with significant side effects. However, oral ingestion of aloe vera is potentially toxic. Under guidelines of California Proposition 65, orally ingested non-decolorized aloe vera leaf extract has been listed by the OEHHA, along with goldenseal, among chemicals known to the state to cause cancer or reproductive toxicity. In addition, IARC studies have found that ingested non-decolorized liquid aloe vera is a possible carcinogen when eaten or ingested by humans.

What is Aloe Vera?

Aloe Vera is a species of Aloe native to northern Africa. It is a stemless or short-stemmed succulent plant growing to 80-100 cm tall, spreading by offsets and root sprouts. The leaves are lanceolate, thick and fleshy, green to grey-green, with a serrated margin. The flowers are produced on a spike up to 90 cm tall, each flower pendulous, with a yellow tubular corolla 2 to 3 cm long.

Aloe Vera has long been a popular houseplant.

Often called the 'miracle plant' or the 'natural healer,' Aloe Vera is a plant of many surprises. It flourishes in warm and dry climates; to many people, it looks like a cactus with fleshy thorny leaves. It is a member of the Lily family, staying moist where other plants wither and die by closing its pores to prevent moisture loss.

There are around 400 species of Aloe, but it is the Aloe Barbadensis Miller (Aloe Vera or "true aloe") plant that has been of most use to humanity because of the medicinal properties it displays.

The Aloe Vera Plant

Although there are many Aloe, the term Aloe Vera ("true Aloe") refers to the Aloe Barbadensis Miller. Fully grown, the plant stands 60 to 90 cm high, and a mature leaf is 7 to 10 cm across at the base, weighing 1.5 to 2 kg.

The lower leaf of the plant is used for medicinal purposes. If the lower leaf is sliced open, the gel obtained can be applied to the affected area of the skin. Leaves and seeds are the two edible parts of Aloe Vera.

The Aloe leaf structure is made up of four layers:

• Rind - the outer protective layer;
• Sap - a layer of bitter fluid which helps protect the plant from animals;
• Mucilage Gel - the inner part of the leaf that is filleted out to make Aloe Vera gel.
• Aloe Vera (inner gel) - contains the eight essential Amino Acids that the human body needs but cannot manufacture.

Aloe Vera has a bitter taste which can be unpleasant in the raw state. It is possible to get used to the taste of plain Aloe Vera gel, but if you can't, adding some fruit juice helps make it more palatable.

There is much confusion between Aloe Vera Gel and Aloe Vera Juice, with the two often thought synonymous. The term Gel only refers to the inner leaf, whereas Juice refers to "Aloe Latex," a bitter substance found just under the leaf's skin.

Leading authorities on Aloe Vera maintain that only Aloe Vera gel, as fresh as preservation allows from the inner leaf, has remarkable properties.
