Within the last few decades we’ve become aware of the colonies of bacteria, microbes, and bugs that live on and in us. At first they seemed like enemies to eradicate, then we discovered that many are benign of beneficial, now researchers have used some of the beneficial ones to help people who have an insufficient supply. Eczema patients were treated with a typically normal skin bacteria that was grown in greater quantities in a lab. The bacteria were then mixed into a moisturizer and applied to five patients. All five patients saw significant improvements, with two of them experiencing a complete eradication of the ailment’s harmful germ. While this is a success for eczema patients, it is also a milestone for successfully using human protection systems naturally. Identification of the elements of the human microbiome may treat otherwise untreatable conditions, and may do so at costs that are lower than pharmaceuticals because they use naturally occurring organisms.
