Recently numerous studies have discovered that 2 brain receptors known as CB 1 and CB 2 respond to the presence of CBD. These are the key receptors that play a role in the hearing abilities and balancing of the human body. This has left people to wonder if CBD oil can really help hearing disorders such as tinnitus. However, there is not a lot of data to tell anything conclusively yet. Another study showed that, while experimenting on lab rats, the CBD oil did not have any helpful effect on the rats. It also seemed to worsen the tinnitus in some rats. Despite this, there are scientific backings to the claim that CBD can help people cope up with stress. An issue in Neurotherapeutics suggested that CBD is, in fact, effective in reducing anxiety, PTSD, SAD, and OCD.
