My 10-year-old son suffers from particularly severe attention and concentration problems and hyperactivity. I started a treatment of pure CBD oil and I noticed that the child is able to do things with less interference. The body responds to it more easily. He manages to understand better what is wanted from him and to be less overwhelmed by himself and by stimuli in the environment. Thanks to the CBD oil we completely stopped taking the Hartlin and the boy continues to show improvement in regards to his problems.
