George Hendrickson, whose son Eliyah was diagnosed with Dravet Syndrome when he was five-months-old by a Colorado doctor, crushes vitamins while mixing different vitamins together for his son on Thursday, June 11, 2015, at their home in Sioux Falls. "We know of other children with Dravet that couldn't walk and talk until they went on CBD--the cannabis oil--then within 5 to 6 months these kids would cut their seizures down by 90 to 95 percent or more and would learn to walk and talk."
