I always have an aloe vera plant on my patio and it grows and grows and grows.  I cut little growths off the side to give to my neighbors for their health also.  You just put the little growths in water for three days and it will sprout little roots and you can plant this and it will start growing for your natural health needs. 
(NaturalNews) It has been proven that aloe vera can be used to treat  acne, with improvements seen in as little as one week. Acne sufferers  can see a remarkable improvement by simply breaking an aloe vera leaf  and applying the watery gel to the acne lesions. It should be noted that  aloe vera does not "cure" acne, but it greatly reduces the swelling,  inflammation and redness associated with acne. Further, if you use the  aloe vera every day, it will help prevent acne outbreaks. In addition to  treating acne, the hidden secrets of this simple plant are being used  for the treatment of many other skin problems.
To increase the  vitality of your skin, drink some freshly-squeezed organic aloe vera  juice daily. To make aloe vera juice, simply pick the largest leaves  from an aloe vera plant in the afternoon, clean away all dirt and debris  and process the leaves in your juicer. It is recommended that you drink  between 2-4 ounces, twice a day. For added flavor, you can mix the aloe  vera juice with some organic carrot juice.
