Just some background information.
CBD (Cannabidiol) is one of the 104 chemical compounds known as cannabinoids found in the cannabis or marijuana plant,
Cannabis sativa.
(THC) Tetrahydrocannabinol is the main psychoactive cannabinoid found in cannabis, and causes the sensation of getting “high” that’s often associated with marijuana. However, unlike THC, CBD is not psychoactive.
My better half had a UK client who was growing marijuana under license somewhere in the UK, where they were trying to "breed" a plant with less THC and more CBD.
It seems that Marijuana has been used for pain relief since 2900 B.C. (

Using CBD has been shown to reduce anxiety and depression in both human and animal studies.
Though CBD has been shown to help reduce symptoms related to cancer and cancer treatment, and may even have cancer-fighting properties, more research is needed to assess its efficacy and safety.
CBD may have beneficial effects on acne due to its anti-inflammatory qualities and its ability to control the overproduction of sebum from the sebaceous glands.
Though research is limited at this time, CBD has been shown to effectively treat symptoms related to epilepsy and Parkinson’s disease. CBD was also shown to reduce the progression of Alzheimer’s disease in test-tube and animal studies.
Though more human studies are needed, CBD may benefit heart health in several ways, including by reducing blood pressure and preventing heart damage.
There’s a medically approved cannabis-based treatment called Sativex, but it doesn’t work for everyone. In most parts of the UK you can’t get it from the Health Service (NHS). That’s because the good it does is seen as too small to be worth what it costs. And for many people it’s too expensive to buy privately. Some people with MS get cannabis to help ease their symptoms in other ways.
Some studies suggest that CBD may be an effective treatment for
diabetes, substance abuse, mental disorders and certain types of cancers. However, more research in humans is needed.

I think most people have heard of the young lad with epilepsy whose mother went through hoops before the home secretary allowed doctors to prescribed medicinal cannabis. My understanding is that this is different to CBD oil which can be extracted from hemp in that it will contain some THC and that there is debate over the % of each to be most effective.
