Marijuana was used as a painkiller in prehistoric times, and sources say traces of its use for this purpose date back to 2900 B.C.
Today, scientists have found that certain compounds in marijuana, including CBD, are responsible for its pain-relieving properties.
The human body is equipped with a specialized system called the endocannabinoid system (ECS), which is responsible for the regulation and proper functioning of many key life processes including sleep, appetite, pain and the efficiency of the immune system.
The body produces endocannabinoids, which are neurotransmitters that bind to cannabinoid receptors in the human nervous system.
Research has shown that CBD may help reduce chronic pain by influencing the activity of receptors in the endocannabinoid system, reducing inflammation, and interacting with neurotransmitters.
For example, one study found that CBD injections reduced pain after surgical procedures in laboratory animals. Another study found that orally administered CBD significantly reduced both the pain and inflammation associated with inflammation of the sciatic nerve.
Several human studies have unequivocally shown that the combination of CBD and THC (the legal THC content in consumer products, including CBD oil is 0.2%), is effective in treating rheumatic pains and pains associated with progressive symptoms of multiple sclerosis.
One study in a group of 47 people with multiple sclerosis found that patients treated with a combination of CBD and THC over a period of one month experienced a significant improvement in quality of life, a reduction in pain and sore muscle spasms compared to the placebo control group.
Another study showed that the above-mentioned preparation significantly reduced pain during movement and at rest, as well as the quality of sleep in 58 people suffering from severe rheumatoid pains.
