There is some promising evidence of the effectiveness of CBD oil in neuropathic and inflammation-related pain.
CBD oil has anti-inflammatory and antispasmodic properties and could therefore contribute to pain relief. However, CBD cannot eliminate the causes.
CBD oil has the advantage over strong pain relievers that there are hardly any proven side effects (more on that in a moment) and it does not make you addicted.
2. Stress and Anxiety disorders
Studies indicate positive effects of CBD oil on panic attacks and anxiety disorders. Anxiety disorders are controlled by the amygdala, a core area of the brain. In situations of fear and anxiety, messenger substances are released that impact the body (e.g. trembling or sweating).
CBD oil can bind to cannabinoid receptors of the body's endocannabinoid system (ECS) and inhibit the release of anxiety messengers. The ECS in particular is suspected to be able to regulate fear through special signals.
Studies suggest that CBD oil may stimulate hippocampal (neurogenesis) healing. The hippocampus is situated in the brain and often shrinks in the event of depression.
This reduction (also called atrophy) could be counteracted by CBD oil by protecting the nerve cells.
Both (the psychoactive) THC and CBD oil have already proven beneficial in animal models for depression. However, this has not been clinically studied in humans. More on how CBD can help with depression here.
The studies on CBD and cancer are limited so no definitive promises should be made. Nevertheless, there are promising results suggest CBD oils could help curb the growth of cancer cells and cause the infected cells to die.
CBD oil can also be used to combat side effects such as pain, nausea and depression. Cannabinoids - also sometimes known as phytocannabinoids - could be used in conjunction with other therapeutic options such as chemotherapy.
5. Multiple Sclerosis
CBD oil has anti-inflammatory and analgesic effects. CBD cannot cure multiple sclerosis. But it could alleviate the symptoms of MS and give patients significant relief.
Because MS patients often suffer from inflammation spots that may be alleviated by CBD oil. The pain-relieving effect of CBD oil could also be beneficial and CBD has been reported to improve quality of life and reduce spasticity.
In some scientific studies on the effectiveness of CBD, epilepsy patients showed a significant improvement. The number of epilepsy attacks and falls could be significantly reduced by taking CBD oil.
The efficacy of cannabis and its constituent cannabinoids in alleviating the effects of epilepsy has been acknowledged by the UK government in 2018 when legalising medicinal cannabis after the personal testimonies of people suffering from epilepsy.
7. Arthritis and Osteoarthritis
There are no confirmed results yet. However, scientific studies show that CBD oil can relieve chronic pain and inflammation. Targeted animal testing of CBD oil in osteoarthritis and arthritis has already been successful.
A recent survey (2019) found that 54% of arthritis patients in the US have had very positive experiences with CBD oil or even medicinal THC.
8. Sleep Disorders
Surveys from the USA show that one of the largest areas of application of CBD oil is to help with sleep. Many people report a calming effect, which means CBD oil can help make falling asleep easier.
It is proven that CBD interacts with the endocannabinoid system, which according to studies is said to have an impact on the sleep rhythm.
It should be noted that there are studies that indicate CBD has no direct impact on sleep as well, so the science is actually inconclusive. Nevertheless, CBD can have an indirect positive impact on sleep disorders by relieving anxiety and stress and the large volume of personal testimonies are also worth bearing in mind.
