Interesting that you've mailed Dr. Knight. Please post her response when available ; ) I'm searching high and low also for natural treatment of brain parasites. Haven't got any seizures, but I bet some microscopic critters are there too. I'll also post if I find any info....
Thought I'd mention that N-acetyl cysteine (almost the same as L-cysteine) chelates mercury and protects against parasites in the intestines like L-cysteine does. NAC thins the mucous making it hard for the critters to attach themselves to the lining...I guess what I'm saying is that you get double the benefits...
