Aloe vera is an evergreen PERENNIAL succulent with serrated stemless fleshy leaves containing a clear gel. Sometimes the leaves have white markings. The flower spikes are orange or yellow and generally borne in autumn to winter.
Aloe vera has many medicinal uses, from the clear sap being a first-aid for burns and wounds to the yellow sap from the leaf bases which is digestive and laxative. Aloe also has many cosmetic applications, and is said to help purify the air of the room it grows in.
