Humans have used aloe vera therapeutically for over 5,000 years. It is truly a medicinal plant, full of nutritional benefits. It contains 20 minerals, 19 of the 20 amino acids required by the body, and 12 vitamins. Aloe vera also provides the enzymes lipases and proteases, which aid in digestion; saponins, which are substances that exert a powerful anti-microbial effect against bacteria, viruses, fungi, and yeast; and salicylic acid, which when used topically helps to break down dead tissue. When taken orally, aloe vera acts as an anti-inflammatory. No wonder it is used for such a wide range of remedies.
