I think she means that people should read her book, use her device, and do exactly what she says. She is getting old. She needs to be taking Iodine. This is Texas. She has been arrested. Threat of going to prison will make you paranoid. She seems like a gun shy little old lady, who's afraid to say what's really on her mind. They will arrest her if she sells a device that kills parasites, so she's selling a device that will detect the harmful toxins that makes us vulnerable hosts. It's a sad situation.
Let's say the device doesn't cure parasites. It reduces the parasite load and they eventually come back. What's wrong with selling something that makes people feel better temporarily and buys them some quality time?
