Aloe vera, Image from Wikimedia CommonsAloe vera is a perennial, tropical & subtropical, succulent plant that grows up to 4 feet tall and has tough, fleshy, spear-like leaves that can grow up to 36 inches long. The inner part of the fleshy leaves contain transparent thick gel (Aloe gel/Aloe latex/Aloe juice) which has medicinal properties. Archaeological evidences suggest that Aloe vera has been medicinally used as early as the Egyptian civilization. Botanists and herbal doctors like Dioscorides and Pliny the Elder had written about Aloe vera plant and its medicinal uses. It has been the most prescribed herbal medicine throughout the 18th and 19th century. Today, Aloe vera is not only used as herbal remedy but also used as dietary supplement and additive for food, beverages, cosmetics, and skin care products. Aloe vera’s ability to treat various diseases such as cancer and diabetes is now being explored by scientists.

Aloe vera gel contains different types of glycoproteins and polysaccharides including mannans, polymannans, anthrones, anthraquinones, and lectins. The biochemical and pharmacological properties of each of these compounds are now being investigated both in animal and human studies.
