Two additional studies in this area were done using CBD oil. In the first one, 214 participants would take 0.9 to 2.3 grams of oil per 1 pound of body weight. CBD successfully reduced seizures by a median of 36.5%. The second study focused on children who suffered from Dravet syndrome. Dravet syndrome is a type of epilepsy that happens in early infancy. Normally high temperatures and fevers trigger it. The results of the second study showed that CBD oil reduced seizures significantly.
