Pain relief is possible.
Since 2900 B.C., cannabis has been used to treat pain (2Trusted Source).
Scientists have recently discovered that certain components of cannabis, including CBD, are responsible for its pain-relieving properties.
The endocannabinoid system is a specialised system in the human body that regulates a variety of functions such as sleep, appetite, pain sensation, and immune system response (3Trusted Source).
Endocannabinoids are neurotransmitters produced by the body that bind to cannabinoid receptors in the nervous system.
Several human studies have found that combining CBD and THC is effective in treating pain associated with MS and arthritis.
Sativex (nabiximols), an oral spray containing a 1:1 mixture of THC and CBD, is approved in several countries to treat pain associated with MS.
A study involving 47 people with MS looked at the effects of taking Sativex for a month. The participants’ pain, walking ability, and muscle spasms all improved (7Trusted Source).
Could alleviate symptoms associated with some mental health disorders
Anxiety and other mental health disorders can have a negative impact on one’s overall health and well-being.
Pharmaceutical drugs are frequently used to treat mental health disorders, which can result in drowsiness, agitation, insomnia, sexual dysfunction, and headaches (11Trusted Source).
Furthermore, medications such as benzodiazepines have the potential for addiction and may result in substance use disorder.
In a Brazilian study, 57 men were given either oral CBD or a placebo 90 minutes before a simulated public speaking test. The researchers discovered that a 300-mg dose of CBD reduced anxiety significantly during the test (12Trusted Source).
There was little to no effect reported in those who took the placebo, a 150-mg CBD dose, or a 600-mg CBD dose (12Trusted Source).
Certain cancer-related symptoms may be alleviated.
CBD may help alleviate some cancer-related symptoms and side effects, such as nausea, vomiting, and pain.
An older study examined the effects of CBD and THC in 177 people suffering from cancer-related pain who had not found relief from pain medication.
Those who received an extract containing both compounds reported significantly less pain than those who received only THC extract
If you have cancer and want to use CBD or other cannabis-derived products, you should talk to your doctor first. These products may not be suitable, safe, or effective for all cancer patients.
Neuroprotective properties may exist.
CBD’s ability to act on the endocannabinoid system and other brain-signaling systems, according to researchers, may provide benefits for those suffering from neurological disorders.
Indeed, one of the most researched CBD applications is in the treatment of neurological disorders such as epilepsy and multiple sclerosis. Despite the fact that research in this area is still in its early stages, several studies have yielded promising results.
Sativex has been shown to be a safe and effective treatment for MS-related muscle spasticity.
It reduced spasms in 75% of 276 people with MS who were experiencing medication-resistant muscle spasticity (19Trusted Source).
Heart health may benefit.
Some research has linked CBD to a variety of heart and circulatory system benefits, including the ability to lower high blood pressure.
High blood pressure has been linked to an increased risk of a variety of health problems, including stroke, heart attack, and metabolic syndrome (24Trusted Source).
CBD appears to be beneficial for people with high blood pressure, according to research.
In a small study, nine healthy men were given 600 mg of CBD oil. When compared to a placebo, the CBD treatment reduced resting blood pressure (25Trusted Source).
The men also participated in stress tests, which normally raise blood pressure, in the same study. Interestingly.
Other potential advantages.
CBD has been studied for its role in treating a variety of health issues in addition to those listed above.
