CBD has shown some potential in treating many different types of pain. A study from the European Journal of Pain showed, using animal models, that CBD can help lower pain and inflammation caused by arthritis. A separate study demonstrated that CBD can inhibit inflammatory and neuropathic pain, two of the most difficult forms of chronic pain to treat.
In 2018, Pediatric Dermatology published a study on three cases of topical CBD use in children with a rare, blistering skin condition known as epidermolysis bullosa. Applied by their parents, all three patients reported an improvement in pain management, faster wound healing and fewer blisters overall. One patient was able to completely stop their course of oral opioid analgesic pain medication. The patients reported no adverse effects.
Few clinical trials have explored the pain-relieving effects of CBD on chronic neuropathic pain but some research suggests the presence of CBD and THC together can work in sync to help reduce pain. Known as the entourage effect, this is being further researched and needs more data to be fully validated.
To treat pain with CBD you can safely start with any amount up to 50mg per day while the maximum currently advised by the UK Food Standards Authority is 70mg per day.
