Cannabis has been at the centre of one of the most exciting and underreported developments in modern science. Research on marijuana’s effects led directly to the discovery of previously unknown biochemical communication system in the human body Endocannabinoid System, which plays a crucial role in regulating our physiology, and mood, and everyday experience.
The discovery of receptors in the brain that respond pharmacologically to the cannabis and the subsequent identification of the endogenous cannabinoid compounds in our bodies that bind to these receptors has a significantly advanced our understanding of human biology, health, and disease.
It is an established scientific fact that the cannabinoids and the other components of cannabis can modulate many physiological systems in the human brain and body. Cannabinoids are chemical compounds that trigger cannabinoid and other receptors. There are more than 100 cannabinoids that have been identified in the marijuana plant. These marijuana molecules, tetrahydrocannabinol (THC) and cannabidiol (CBD) have been studied most extensively.
In addition to cannabinoids produced by the plant, there are endogenous cannabinoids (such as anandamide and 2AG) that occur naturally in the mammalian brain and body, as well as synthetic cannabinoids created by pharmaceutical researchers.
Extensive preclinical research indicates that CBD has potent anti-tumoral, antioxidant, anti-spasmodic, anti-psychotic, anti-convulsive, and neuroprotective properties. CBD directly activates serotonin receptors, causing an anti-depressant effect, as well.
Tetrahydrocannabinol (THC) offers hope of a non-toxic therapy that could treat aggressive forms of cancer without any of the painful side effects of chemotherapy.
Recent years scientists associated with the International Cannabinoid Research Society (ICRS) have elucidated there are several molecular pathways through which the CBD exerts a therapeutic impact.
For example, a preclinical study by Dr Sean McAllister and his colleagues at the California Pacific Medical Centre in San Francisco report on how CBD destroys breast cancer cells by down-regulating a gene called ID-1, which is implicated in several types of aggressive cancer. Silencing the ID-1 gene is a potential strategy for cancer treatment.
Cannabidiol offers hope of a non-toxic therapy that could help you treat aggressive forms of cancer without any of the painful side effects of chemotherapy, “says McAllister”.
CBD and THC Synergy
According to McAllister’s lab, the best results were obtained when CBD was administered along with THC. Several studies underscore the therapeutic advantages for combining CBD and THC - particularly for treating peripheral neuropathy, a painful condition associated with cancer, multiple sclerosis (MS), diabetes, arthritis and other neurodegenerative ailments.
Clinical research conducted by GW Pharmaceuticals, a British company, has also shown that CBD is most effective as an analgesic when administered in combination with whole plant THC.
