CBD has shown the power to act on serotonin receptors, that special part of the brain that helps regulate mood. Another part of the brain that’s important to note is the hippocampus. In people who suffer from anxiety, typically they are found to have smaller than normal hippocampuses. CBD can help here as it promotes neurogenesis, the creation of new neurons. When these new neurons are formed, the hippocampus may benefit and increase in size. In one study, a dosage of 300mg of CBD was seen to be the most beneficial in helping the participants manage their nerves during a public speaking events. In animals it has even shown an antidepressant effect.
Here’s a better rundown of some of the science thought to be behind the benefits of CBD and anxiety.
