Among medicinal plants, the aloe vera plant is the undisputed king. People have been using this plant for thousands of years. People knew about the soothing effect of the aloe vera plant, especially for skin and burn injuries. Today, over three hundred species of aloe vera are known, but not every species has proven beneficial properties. The aloe vera extract is a real specialty: It contains many valuable ingredients that are purely biological - as well as enzymes, vitamins, minerals, bioflavonoids, sugars and essential amino acids. The special feature, however, is that all ingredients are in a balanced relationship to each other. Research speaks of a synergetic effect.
