I was ignorant of the possibility of having parasites in the brain until my friend, who is an emergency room nurse, shared with me that she was caring for a patient who had them. She said it was very difficult to treat his case, but I'm not sure if it is common for it to be very dangerous or if there was something different about this particular case.
Then, I read Hulda Clark's books and learned that, according to Dr. Clark, parasites can get into any organ we have and even in muscles.
I believe parasites may be far more widespread a factor in heart disease, neurological disorders and other health challenges than is currently understood. They are not just a colon problem.
