Aloe is famous for its skin-healing properties. Fresh aloe gel yields the best results: break off a leaf, slice it down the middle, and apply to the skin.

They all have inhibitory action on fungi, bacteria and viruses. Aloe vera gel has been reported to have a protective effect against radiation damage to the skin. Internally, an extract of Aloe works effectively as a laxative, but it may cause severe intestinal pain, so it is no used for this purpose very often anymore. This plant has also been recommended for many other ailments including amenorrhea, asthma, colds, convulsions, hemorrhages, and ulcers. However, no scientific evidence supports the use of Aloe for these problems. The results of the two-year NTP study of a whole leaf Aloe vera extract givenn in an animal’s drinking water showed clear evidence of carcinogenic activity in male and female rats, based on tumors of the large intestine. There was no evidence of carcinogenic activity in mice. So you must think twice before taking Aloe vera orally.

How to grow Aloe

Aloe requires a minimum temperature of about 41F. It is easily cultivated from offshoots that grow at the base of the plant. A well drained soil with some limestone is the best for Aloe vera, but it will grow in soil low in nutrients as well. Aloe prefers full sun but tolerate some shade. It does not require frequent watering. During the spring and summer, water when the soil has become moderately dry. In the winter, allow the soil to dry completely between waterings. The plant will grow for years in the same pot if it has good soil. It grows best when the roots are rather crowded. If you want to repot it, do it in late winter or spring. When harvest, cut the outmost leaves (the oldest) first. New leaves grow from the center of the plant.
