Inside the Bluegrass Hemp Oil store in Lexington, Kentucky, the CBD oils and lotions lining the walls have an origin story — a story of a family’s struggle. “We took a huge risk, to be perfectly honest, because we didn’t know. We weren’t trying other people’s CBD products that were out there,” Bluegrass Hemp Oil Co-owner Adriane Polyniak, said. Polyniak’s son, Colten, began inexplicably having violent seizures in 2009 when he was three. He was diagnosed with idiopathic generalized epilepsy.
