Cbd Oil And The Endocannabinoid System 101
The mechanisms involved in the latter are complex and involve both peripheral and central phenomena. Central sensitization is also associated with the activation and/or recruitment of glial cells within the nervous system which modulate neuronal responses through the initiation of multiple signalling cascades.
However, among the pharmacological strategies under investigation, endocannabinoids and endovanilloids , in addition to enzymes that regulate their metabolism, represent a promising therapeutic avenue to a successful pain treatment. Spinal endocannabinoids and CB1 receptors located on inhibitory dorsal horn interneurons might thus act as mediators of heterosynaptic pain sensitization and play a hitherto unexpected role in dorsal horn pain-controlling circuits. The Cannabis sativa plant has been exploited for medicinal, agricultural, recreational and spiritual purposes in diverse cultures over thousands of years.
- When researchers first began to explore the composition of THC in more detail – one of the most wellknown cannabinoids found in the hemp plant – they stumbled across the endocannabinoid system at the same time.
- One possible conclusion is that CBD in fact prevents endocannabinoids from being broken down by the system’s enzymes, which in some way manages to intensify the effects of other cannabinoids on the human body.
- Weaving cannabis into our lifestyles is a natural process that our bodies are already equipped to carry out.
- In the 1990s, Mechoulan discovered and identified two endocannabinoids, anandamide and arachidonoylglycerol (2-AG), which are produced by the human body and work with receptors that are distributed across the entire body.
Cannabis seeds were initially used for food and textiles made from its hemp in China . The first recorded use of Cannabis as medicine in Chinese pharmacopoeia dates to 2727 BC; Cannabis is later mentioned (1200–800 BC) in the Hindu sacred text Atharvaveda as ‘Sacred Grass’, one of the five sacred plants of India . The development of synthetic cannabimimetic drugs has aided in the pharmacological characterization of an endogenous system, which responds to THC. The serendipitous identification of a G-protein-coupled cannabinoid receptor at which this compound is active in the brain gave birth to an explosion in endocannabinoid research which continues to this day. In spite of recent scientific findings, there is much that remains to be discovered as to where and when endocannabinoids function, and how endocannabinoid signalling may be targeted for therapeutic benefit.

The activation of microglia and astrocytes in the dorsal horn of the spinal cord plays a critical role in the development of facilitated nociceptive responses and spinal hyper-excitability in chronic pain models . Chronic pain and neuropathic pain are indications for which there is high unmet need in the clinic . Furthermore, chronic neuropathic pain can persist for months, without the underlying cause being treatable or identifiable.
Although majority of the effects of cannabinoids are mediated through CB receptors, AEA has been shown to induce its effects on cancerous cells by interacting with TRPV1 receptor or cholesterol rich lipid rafts . Furthermore, it has been reported that signaling pathways are differentially regulated by cannabinoids in normal cells versus cancer cells. Moreover, many animal studies have reported anti-proliferative and pro-apoptotic effects of cannabinoids on tumor cells but not on normal tissue . Thus the role of the endocannabinoid system in cancer indicates that this system is involved in regulating many of the functions that are essential in cancer development.
Indeed, only one in four patients experience over 50 per cent pain relief . No single target has been shown to be uniquely associated with the establishment of neuropathic pain.
Nociceptive pain results from the detection of intense or noxious stimuli by specialized high-threshold sensory neurons , a transfer of action potentials to the spinal cord, and onward transmission of the warning signal to the brain. In contrast, clinical pain such as pain after nerve injury is characterized by hyperalgesia in the absence of a stimulus and reduced nociceptive thresholds so that normally innocuous stimuli produce pain.
