Cbd is mostly for pain relelief. That's what the chemical is. And a lot of people use cbd oil for fibro that I know. :) just know everyone is different and has different tolerances so the first time might not help at first if you don't take enough for your body :)
I've been using a menthol/CBD oil rub recently, burned the first time but has really good pain relief. It's different than my other meds, that's for sure. Plus, it smells like peppermint with the menthol.
