A parasite is anything that lives or feeds off of its host at the expense OF the host.
Let’s get one thing straight, if you think you are immune to parasites you are WORNG. Per the CDC 60% of the population is estimated to have parasites but that number is realistically more like 90%. Parasites are everywhere, our food, water, the soil, and even the air. They are acquired in all sorts of ways, bug bites, sexual activity, and can even be passed on in utero. If you haven’t gotten the hint yet they don’t just exist in third world countries or from eating raw sushi. Testing for parasites is wildly inaccurate which is why more often than not they go undetected and are overlooked by conventional medicine. Part of the parasitic function is to remain undetected. For that reason the most reliable form of testing to diagnose include muscle testing and bio resonance.
