Because Aloe Vera plants are very succulent and consist of 95% water, they are extremely frost tender. If they are grown outdoors in warm climates, they should be planted in full sun, or light shade. The soil should be moderately fertile, and fast draining. Established plants will survive a drought quite well, but for the benefit of the plant, water should be provided. The medicinal properties of Aloe vera have been known and recorded since biblical times. It has been used for a variety of ailments, and as an ointment for burns, cuts, and rashes, as well as an ingredient in various beauty preparations.
The sap of the Aloe is a thick, mucilaginous gel. It is this gel which is used medicinally. The outer skin has essentially no value, but because it is commercially easier and less expensive to utilize the entire leaf, 'whole leaf' Aloe juice has been hyped as the 'best'. This is not the case.
