Wormwood is the only herb that can cross the blood-brain barrier. Albendazole is a pharma drug that can, but you REALLY REALLY need an MRI before you do Albendazole, because if you have cysts in your brain, and they rupture while taking Albendazole, you can die.
If you take Wormwood , take exactly as directed and then only for two weeks at a time, then two weeks off. It can be very dangerous if taken at high doses or for two long.
