A few years ago, my mom gave me CBD oil to help me focus at school. Just a bit under my tongue. It tasted like orange peels without the bitterness. It did help with that, but most people use it for chronic pain. They either smoke Marijuana with high CBD content or use some other CBD product for pain relief. I have arthritis, and the CBD works quite a bit. so.. to sum it up, it helps with gone brain and ow bones.
