Aloe (genus of succulent plants)

Key characteristics

Aloe leaves typically contain a clear inner gel and a bitter outer sap, which have different traditional uses. Plants often use CAM (crassulacean acid metabolism) to minimize water loss. Inflorescences are usually erect spikes or racemes of tubular, often brightly colored flowers that attract pollinators such as birds and insects. Distinguishing features include leaf arrangement, presence of teeth or spines, and flower shape.

History and cultivation

Species of Aloe have been used by people for centuries in folk medicine, cosmetics and as ornamental plants. The most widely recognized species, Aloe vera, is cultivated extensively for its gel and extracts and appears in many skincare and healthcare products. Cultivation practices and commercial propagation are discussed in horticultural guides; see cultivation resources. The wild origins and historic range of some commonly cultivated species are often unclear; some authorities note that wild populations of Aloe vera are rare or uncertain in origin (wild status notes).

Uses and examples

• Traditional topical remedies for minor burns and skin irritations.
• Cosmetic and pharmaceutical extracts marketed for moisturizing and soothing properties.
• Ornamental use in gardens, containers and xeriscaping for drought-prone areas.
• Some species are grown for cut flowers due to their striking inflorescences.

Conservation and distinctions

A number of Aloe species face threats from habitat loss, overharvesting and illegal trade, prompting regional conservation measures. Aloes are sometimes confused with agaves and other succulents; key distinctions include growth habit and flower morphology. For additional species information and conservation status, consult botanical references and conservation databases such as species lists and resources.
