Brazilian research from 1973 showed that CBD actively reduced or blocked convulsions in rodents, which was confirmed by another study conducted a year later.
In another double-blind study, epileptic patients that
received 200-300 mg of CBD per day had fewer seizures.
One of the most well-documented examples was a young girl named Charlotte Figi who suffered from Dravet’s Syndrome, a rare condition that conventional medication was not effective in treating. She was given a tincture derived from a very specific strain, known for its low-THC and high-CBD levels, which later became known as
Charlotte’s Web. Today Charlotte lives a healthy life, and her seizures have been drastically cut down to two or three a month, from around 300 seizures a week.
In June, 2018 the U.S. Food and Drug Administration approved Epidiolex, a CBD-based drug for treating
seizures in patients two years old and above. Epidiolex is the first drug to gain FDA approval
