Botanical Overview
Bitter Aloes (Aloe vera) is a flowering plant in the Aloeaceae family. The traditional uses of this species reflect its genuine medicinal value, validated by generations of practical experience. This species belongs to the Aloeaceae family, a group of flowering plants.
General Description
It is widely distributed, and is considered an invasive species in many world regions. An evergreen perennial, it originates from the Arabian Peninsula, but also grows wild in tropical, semi-tropical, and arid climates around the world. It is cultivated commercially and has been used for centuries as a topical treatment. The species is considered attractive for decorative purposes, and is often used indoors as a potted plant. The leaves of Aloe vera contain significant amounts of the polysaccharide gel acemannan, which may be used for topical purposes. The leaves also contain aloin, which is a toxic compound. Aloe vera products are typically made from the gel. Aloe vera acemannan may be used in skin lotions, cosmetics, ointments and gels for minor burns, skin abrasions, insect bites, and windburn. Oral ingestion of aloe vera extracts may cause acute abdominal pain and cramps, and hepatitis if consumed chronically. It should not be used during pregnancy. Some people have allergic reactions to aloe when used on skin.
