Can CBD Help With Inflammation?
CBD is a non-psychotropic molecule produced by the cannabis plant. Researchers believe it could help combat inflammation, and may play a role in pathological and athletic populations for this reason.
CBD is becoming increasingly popular amongst researchers and scientists for its versatility. The non-psychotropic cannabinoid has been studied in relative depth over recent years, and is displaying some encouraging results in regard to its potential anticonvulsant[1], neuroprotective[2], and antioxidant properties[3]. Studies[4] have also implicated the cannabinoid as a supportive aid for reducing inflammation. Inflammation is thought to be a contributing factor to various chronic diseases.
CBD AND THE ENDOCANNABINOID SYSTEM
CBD is formed within the trichomes of the cannabis plant as a secondary metabolite. The molecule interacts with the human body in numerous ways and exerts effects partly via serotonin and vanilloid receptors. Much like other cannabinoids, CBD can also influence the endocannabinoid system. This system is comprised of cannabinoid receptors (CB1 and CB2) that are found upon the cell membrane of many different cell types throughout the body.
Several cannabinoids achieve their medicinal effects by binding to these receptors sites. Although CBD does not directly bind to these receptors, and is in fact a known antagonist, it does sill influence the endocannabinoid system in an indirect manner. It has the ability to both enhance and reduce the binding action of certain receptors and also acts as an anandamide reuptake inhibitor.
What is anandamide, you ask? Superb question. Anandamide belongs to a class of molecules known as endocannabinoids. These molecules share a very similar shape with cannabinoids from the cannabis plant, or phytocannabinoids, which is why cannabinoids are able to bind to some of the same receptor sites.
WHAT IS INFLAMMATION?
Although often vilified and looked at through a negative lens, inflammation is actually a vital physiological process and a fundamental aspect of the body’s innate immune response. However, too much inflammation is attributed as a contributing factor for chronic diseases such as cancer and rheumatoid arthritis.
Acute inflammation is usually the result of a traumatic injury, such as a sprained ankle or strained muscles, for example, and manifests as pain, redness, immobility, swelling, and heat. This form of inflammation is a response with the purpose of protecting the injured area and triggering the healing process. Specific cells move into the affected site and begin to clear debris and damaged tissues. Although anti-inflammatory medication is often used to hinder this response and deal with the pain, the body does need to undergo this phase, thus the use of these medicines can be seen as controversial. Acute inflammation can also be caused by harmful bacteria.
Chronic inflammation is defined as inflammation that persists over long periods of time and can be caused by pathogens, viruses, and an overactive immune response. This form of inflammation can span from periods of months to years, and can occur when the immune system perceives healthy tissues as a threat and starts to attack them. This is known as an autoimmune disease. Such conditions include asthma, rheumatoid arthritis, Crohn’s disease, and sinusitis.
CBD AND INFLAMMATION
Research into the cannabinoid has shown its potential in helping to mediate the immune response associated with autoimmune diseases such as those mentioned above, along with neuropathic pain[5], hypertension[6], Alzheimer’s disease[7], and depression[8]. A scientific paper[9] regarding this mechanism states that CBD offers promise in the field of anti-inflammatory drug development. The molecule may act to combat inflammation and its associated oxidative stress in numerous ways, including by exerting an immunosuppressive effect on macrophages and microglial cells—cells that play a role in inflammation and immunity.
Further research published[10] in the journal PLOS One investigated the effects of CBD on intestinal inflammation. Application of the cannabinoid led to decreased levels of macrophages within the intestines of mice after CBD treatment, suggesting future therapeutic strategies involving CBD in the treatment of inflammatory bowel diseases.
CBD FOR ATHLETES
Athletes represent a population with a high risk of acute musculoskeletal injury and chronic pathologies. Acute injuries always start with an inflammatory response. Although the findings outlined above are encouraging, there is still a lot we need to learn about CBD’s impact on combating pain and reducing swelling and soreness. Interestingly, that hasn't stopped the World Anti-Doping Agency (WADA) from recently removing CBD from its prohibited substances list. This means Olympic athletes and professional sports players will no longer be penalised for using CBD before or after competing.
