Charlotte’s Web is a medical strain high in CBD, a cannabis compound (or cannabinoid) that has a range of medical applications. Colorado growers the Stanley Brothers created this strain specifically for Charlotte Figi — a young epilepsy patient and medical cannabis user — by crossing an unspecified strain with industrial hemp. The effectiveness of Charlotte’s Web in treating Figi’s seizures was publicized in a CNN special and garnered enough attention to attract droves of families to Colorado in search of similar relief. Charlotte’s Web has spurred a wave of innovation in CBD breeding. Its CBD content usually runs from 15 to 20% — that’s 300 times higher than the CBD of the average recreational strain. THC levels will vary, but are usually quite low.
