Imagine a creature so sinister that it can live inside your body for years, eating your blood, tissue, and food. It grows and reproduces, generation after generation.

Those creatures are parasites, and they range greatly in size and threat. Some are large and easy to spot, such as ticks. But others are far more insidious and can go unnoticed for years, feasting on you unchecked.

Worms and flukes may be squirming around in you right now, but without an understanding of signs, symptoms, or a positive stool test, you may never know.

Despite that parasites are often hard to see, people of the ancient world were very familiar with the problem. Old medical texts contain numerous prescriptions and protocols aimed at ridding the body of various types of internal worm infections.
