So is it worth it to buy pure CBD oil or spend the money on a top-shelf product, with no medicinal "guarantee" that it will have therapeutic effects? That's a decision that you'll have to make personally, but let us leave you with this bit of food for thought: as of June 2018, the FDA has approved its first-ever natural CBD extract (Epidiolex) for prescription use, and many have said that this will just be the tip of the iceberg in terms of high-profile health organizations beginning to attest to the true positive qualities of CBD oil and other CBD-based hemp extracts.
CBD oil contains CBD (and often other active compounds) in a carrier oil. There are a number of forms of CBD oil, including softgel capsules, tinctures, and under-the-tongue sprays. Some forms of CBD oil can also be applied directly to the skin, in the form of products like creams and salves. The concentration of CBD varies from product to product.
