Botanical description and cultivation

Aloe vera, a member of the Asphodelaceae family, is a succulent plant recognized by its thick, fleshy leaves. These leaves, often serrated along the edges, form a rosette pattern and range in color from pale green to grayish-green, sometimes exhibiting white speckles. The inner leaf contains the clear, gel-like substance prized for its medicinal properties, while a yellowish latex, known as aloe latex, resides just beneath the outer skin. Though often referred to as a cactus, aloe vera is, in fact, a close relative of lilies and onions. This fascinating plant thrives in arid and semi-arid climates, favoring well-drained soil and ample sunlight. Its ability to store water in its leaves makes it remarkably drought-tolerant.

Cultivating aloe is relatively straightforward, making it a popular choice for both home gardeners and commercial growers. The plant readily propagates through offsets, also known as “pups,” which sprout from the base of the mother plant. These offsets can be carefully separated and replanted, quickly establishing new aloe plants. Aloe vera prefers warm temperatures and should be protected from frost. When grown indoors, it requires bright, indirect light and infrequent watering, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, a common problem for aloe plants. In optimal conditions, aloe can flourish for many years, providing a readily available source of its beneficial gel.

Commercial cultivation of aloe vera is a significant industry, with large-scale plantations found in regions like Texas, Mexico, and the Caribbean. These operations focus on maximizing gel production for use in a wide range of products, from cosmetics and skincare to dietary supplements and remedies within traditional medicine. Harvesting the aloe gel typically involves carefully filleting the leaves to extract the inner mucilage while minimizing contact with the potentially irritating latex. This process is often done by hand to ensure the quality and purity of the harvested gel. The demand for aloe products continues to grow, driven by increasing consumer interest in natural health and beauty solutions.
