The human body is made up of 30 trillion cells that make up our organs and an equal number of microscopic microorganisms that inhabit the mucous membranes and skin of our body, constituting what is known as the Human Microbiome*.
The microbiome is made up of microorganisms and their habitat (ecosystem).
It performs functions that we are not capable of performing and essential substances for our health and well-being are synthesized in it, constituting the first line of defence against infections by pathogenic and harmful agents.
It is necessary that there is a physical separation between the microbiome and the human body and that the barrier of the skin and mucous membranes remains intact. There must be a bidirectional positive action between the host and the microbiome, so that there is a relationship of symbiosis and health.
