CBD oil can ease anxiety : Several studies have found that the use of CBD oil is helpful in reducing anxiety, meaning it could be a beneficial natural remedy for sufferers. Back in 2011, a study published in the journal Neuropsychopharmacology found that when people with generalised social anxiety disorder (SAD) were given 600mg of CBD oil prior to a public speaking test, as opposed to a placebo, they experienced significantly less anxiety, difficulty and discomfort during their speech.
