Parasites are not always intestinal worms. The head, thyroid, mucus in the chest area, or even in the uterus. Often they are microscopic. A parasite is an organism that lives within, upon, or at the expense of another organism, known as the host, without contributing to the survival of the host. Rather than focus on each type of parasite, let's focus on the reason for their presence and how to evacuate them from the human body.
Parasites have a function.
Decomposing the dead, the unhealthy and the weakened. It is part of nature's system of recycling. Parasites do not like a clean and healthy body, because they have little to feed on. In the human body most parasites start in the intestine. The intestinal system can be compared to your kitchen's food preparation area and place to eat.
