Fortunately for you as a consumer, this is where the benefit of a modern CBD online store with "digital transparency" comes into play. In other words, if you're going to buy CBD oil online, it's imperative that you take into account the customer feedback that's available, as well as information on each brand that's available from third-party websites.
In fact, the U.S. Food and Drug Administration (FDA) approved Epidiolex (a drug made with a purified form of CBD oil) in June 2018 for the treatment of seizures associated with two rare and severe forms of epilepsy in patients 2 years of age and older. These two epilepsy forms are known as Lennox-Gastaut syndrome and Dravet syndrome. Epidiolex is the first FDA-approved drug that contains a purified drug substance derived from marijuana.
