Aloe vera is commonly used to treat sun burns and various skin problems. The gel from aloe vera is loaded with many amino acids, vitamins, and minerals that we need. It is said to be more beneficial to ingest the gel in order to full benefit from the nutrition. When the leaf is cut the gel smells pretty bad though in my opinion and I have yet to taste it!
Aloe vera is a succulent. Use a very well draining soil, one without any peat moss, and with lots of perlite or vermiculite. The roots are very susceptible to root rot. An unglazed clay pot is breathable, which helps moisture escape and allows more oxygen to reach the root system of the plants. The roots are fairly shallow and spread more horizontally rather than deep, so keep this in mind when choosing a pot for it. Your aloe will thrive on neglect and easily die with too much water. I use a cactus 2 7 7 fertilizer in the spring to fall once a month – just follow the instructions of the fertilizer. In the winter you will water less and in the warmer months water it once the top inch of dirt is completely dry. Aloes will easily die in cool weather so be sure to bring it indoors long before a risk of frost outside.
You can buy Aloe ferox seeds on my online store. Aloe Ferox is also used medicinally in the same way as aloe vera; the health benefits and nutrition value is very similar.
