She made concessions to survive. I think she made a deal---'leave my clinic alone (she still ended up moving it to mexico) and I won't disclose what 'cancer' really is and I'll push your dental 'cleanup' agenda'.
But her work is extremely effective at cutting the whole pharmaceutical cartel's parasite based pretend disease industry off at the knees. But she also had a very strong influential group of supporters (nothing like getting your life saved) who fought for her and her work. I'm sure those folks knew what the cartel would try, and protected her best they could.
That's why it took them so long to get to her. They tried to find someone close to her that would betray her for money. Her people were fiercely loyal. I think they never succeeded in that, but I think they finally managed to get one of their saboteurs on her kitchen staff, and they managed to poison her with cadmium. Because it mimics 'cancer' at the end. 'See', they could say---'she's a quack--she couldn't even save herself'. *sigh*
And if you look, she self published, for that very reason. No printing house would accept her work. It was entirely word of mouth 'advertising.
