Since CBD cannabidiol and other compounds in cannabis are so similar to the chemicals created by our own bodies, they are integrated better than many synthetic drugs. According to Bradley E. By understanding this system, we begin to see a mechanism that could connect brain activity and states of physical health and disease.
Reduced Risk of Diabetes and Obesity Several studies have shown that regular cannabis users have a lower body mass index, smaller waist circumferences, and reduced risk of diabetes and obesity. One report published in the American Journal of Epidemiology , based on a survey of more than fifty-two thousand participants, concluded that rates of obesity are about one-third lower among cannabis users.
CBD on its own was shown in to lower the incidence of diabetes in lab rats,[ ] and in an Israeli-American biopharmaceutical collective began stage 2 trials related to using CBD to treat diabetes. Respondents who had used cannabis in their lifetime but were not current users showed similar but less pronounced associations, indicating that the protective effect of cannabis fades with time.
The research emerging about the interplay between cannabinoids and insulin regulation may lead to some major breakthroughs in the prevention of obesity and type 2 diabetes.
A study that measured data from 4, participants on the effect of cannabis on metabolic systems compared non-users to current and former users.
Linked to diet and lifestyle, atherosclerosis is common in developed Western nations and can lead to heart disease or stroke. It is a chronic inflammatory disorder involving the progressive depositing of atherosclerotic plaques immune cells carrying oxidized LDL or low-density lipoproteins.
A growing body of evidence suggests that endocannabinoid signaling plays a critical role in the pathology of atherogenesis. Studies have demonstrated that inflammatory molecules stimulate the cycle leading to atherosclerotic lesions. The CB2 receptor is also stimulated by plant-based cannabinoids.
Reduced Risk of Cancer Could cannabidiol help prevent tumors and other cancers before they grow? A study showed that animals treated with CBD were significantly less likely to develop colon cancer after being induced with carcinogens in a laboratory. Continuing research is focused on the best ratio of CBD to THC and the most effective dose level in cancer prevention and treatment. Cannabinoids are neuroprotective, meaning that they help maintain and regulate brain health.
The effects appear to be related to several actions they have on the brain, including the removal of damaged cells and the improved efficiency of mitochondria. Extra glutamate, which stimulates nerve cells in the brain to fire, causes cells to become over-stimulated, ultimately leading to cell damage or death.
Thus, cannabinoids help protect brain cells from damage, keeping the organ healthy and functioning properly. CBD has also been shown to have an anti-inflammatory effect on the brain. As the brain ages, the creation of new neurons slows down significantly. In order to maintain brain health and prevent degenerative diseases, new cells need to be continuously created.
A study showed that low doses of CBD- and THC-like cannabinoids encouraged the creation of new nerve cells in animal models, even in aging brains.
Cannabinoids are facilitative of the process of bone metabolism—the cycle in which old bone material is replaced by new at a rate of about 10 percent per year, crucial to maintaining strong, healthy bones over time. CBD in particular has been shown to block an enzyme that destroys bone-building compounds in the body, reducing the risk of age-related bone diseases like osteoporosis and osteoarthritis.
In both of those diseases, the body is no longer creating new bone and cartilage cells. CBD helps spur the process of new bone-cell formation, which is why it has been found to speed the healing of broken bones and, due to a stronger fracture callus, decrease the likelihood of re-fracturing the bone bones are 35—50 percent stronger than those of non-treated subjects.
Protects and Heals the Skin The skin has the highest amount and concentration of CB2 receptors in the body. When applied topically as an infused lotion, serum, oil, or salve, the antioxidant a more powerful antioxidant than vitamins E and C  in CBD oil has many benefits and can repair damage from free radicals like UV rays and environmental pollutants.
Cannabinoid receptors can be found in the skin and seem to be connected to the regulation of oil production in the sebaceous glands. In fact, historical documents show that cannabis preparations have been used for wound healing in both animals and people in a range of cultures spanning the globe and going back thousands of years. The use of concentrated cannabis and CBD oils to benefit and treat skin cancer is gaining popularity with a number of well-documented cases of people curing both melanoma and carcinoma-type skin cancers with the topical application of CBD and THC products.
Best known is the case of Rick Simpson, who cured his basal cell carcinoma with cannabis oil and now has a widely distributed line of products. Cannabis applied topically is not psychoactive.
Cannabinoids have been proven to have an anti-inflammatory effect in numerous studies. CBD engages with the endocannabinoid system in many organs throughout the body, helping to reduce inflammation systemically.
The therapeutic potential is impressively wide-ranging, as inflammation is involved in a broad spectrum of diseases. The oral use of cannabis and CBD for anxiety appears in a Vedic text dated around BCE, and it is one of the most common uses of the plant across various cultures. While THC can increase anxiety in some patients, it lowers it in others. However, CBD effects have been shown to consistently reduce anxiety when present in higher concentrations in the cannabis plant.
On its own, CBD has been shown in a number of animal and human studies to lessen anxiety. The stress-reducing effect appears to be related to activity in both the limbic and paralimbic brain areas.
A research review assessed a number of international studies and concluded that CBD has been shown to reduce anxiety , and in particular social anxiety, in multiple studies and called for more clinical trials. It is suggested that patients work with a health care practitioner experienced in recommending cannabidiol or medicinal cannabis so that dosage and delivery methods can be developed and fine-tuned on an individual basis.
At the same time, educated and aware patients can be their own highly informed health consultants. For anxiety, CBD products with a ratio of High-CBD cannabinoids can be very effective in reducing chronic anxiety, treating temporary stress, and protecting the body from the physiological effects of both. Varieties high in linalool, a terpene shared with lavender, are known to be effective for relieving anxiety.
Always start with the micro dose to test sensitivity and go up as needed within the dosing range, before going to the next, until symptoms subside. The micro to standard dose is usually recommended to treat stress and anxiety with CBD. For relief of immediate symptoms, as in a panic or anxiety attack, vaporizing or smoking work well. The medication lasts one to three hours, whereas most ingested products, including CBD oil, take thirty to sixty minutes before taking effect and last six to eight hours.
Herbal vaporizers that use the whole plant are also an effective delivery method. Sublingual sprays or tinctures taken as liquid drops take effect quickly and last longer than inhaled products. The Cannabis Health Index CHI is an evidence-based scoring system for cannabis in general, not just CBD oil effects and its effectiveness on various health issues based on currently available research data.
Using this rubric and based on eleven studies, cannabis rated in the possible-to-probable range of efficacy for treatment of anxiety. Elixinol Organic High Potency CBD Capsules Elixinol offers a highly concentrated, high-potency, organic whole-hemp plant CBD oil , which is naturally extracted with carbon dioxide and free of all synthetics and chemicals.
Whole-hemp plant extracts contain synergistic compounds that are believed to enhance the effectiveness and benefits of CBD. Clinical depression is a serious mood disorder characterized by persistent sadness and loss of interest, sometimes leading to decreased appetite and energy and suicidal thoughts.
Commonly used pharmaceuticals for depression often target serotonin, a chemical messenger that is believed to act as a mood stabilizer. The neural network of the endocannabinoid system works similarly to the way that serotonin, dopamine, and other systems do, and, according to some research, cannabinoids have an effect on serotonin levels.
Whereas a low dose of THC increases serotonin, high doses cause a decrease that could worsen the condition. CBD products with a ratio of Specifically, products made with Valentine X or Electra 4 are more energizing, helping relieve depression.
When low energy is an issue, sativa or other stimulating strains can be helpful for improving energy and focus when THC can be tolerated. Varieties that are high in the terpene limonene are recommended for mood elevation. Always start with the micro dose to test sensitivity and go up as needed within the dosing range before going to the next, until symptoms subside. The micro to standard dose is usually recommended to treat depression.
Vaporized or smoked cannabis is recommended for relief of immediate symptoms, or a boost in dosage, and it can also be useful for sleep issues. The Cannabis Health Index CHI is an evidence-based scoring system for cannabis in general, not just CBD effects and its effectiveness on various health issues based on currently available research data.
Using this rubric and based on twenty-one studies, cannabis rated in the possible-to-probable range of efficacy for treatment of depression. Research in called for clinical trials to look into the effectiveness of cannabinoids for bipolar disorder manic depression. It also works on the GABA-glutamate system and the hypothalamic-pituitary-adrenal axis. Its main role is restoring balance through inhibition when levels are too high and enhancement when they are too low.
This is the most likely reason phytocannabinoids in general and CBD specifically are able to regulate depression and anxiety. The scientific inquiry into cannabis over the past several decades has confirmed that it is an effective and safe analgesic for many kinds of pain. Of all the reasons that people use CBD today, pain is the most common. The same can be said of cannabis in general. In the United States, over seventy million people suffer from chronic pain, which is defined as experiencing over one hundred days per year of pain.
Physicians differentiate between neuropathic usually chronic and nociceptive pains usually time-limited , and cannabis works on most neuropathic and many nociceptive types of pain. At present, it is hard to imagine a better approach than adjusting THC doses individually to balance wanted versus unwanted effects.
Generally, higher doses are needed to achieve analgesic and antiemetic effects. Such high doses preclude an oral use of THC as single substance in humans due to side effects. Many questions are also unsolved when it comes to chronic treatment with cannabinoids, a particularly important point in palliative care.
Full recovery of CB1 receptors after stopping THC for example may take up to several weeks, with regional differences. Is a daily treatment, as commonly practiced, necessary or is a pulse-dosing concept with intermittent dosages given as short cycles a better alternative?
How long last effects? CBD and possibly other non-psychotropic cannabinoids, may be a promising alternative for many indications, likely to include nausea, vomiting and improvement of sleep, although more studies in humans are necessary. Combinations were synergistic under many circumstances such as in pain and antitumor studies.
Cannabinoids differ in their antitumor activities and probably in their mechanisms and targets, which is a rationale for combinations. However, for many pharmacological effects except against tumors roughly times higher daily doses are needed for CBD compared to THC.
This leaves some doubts as to whether a 1: A further, unsolved question is whether the common intervention strategy of 1 to 3 applications of cannabinoids per day can be optimized. More recent findings demonstrate that the activity of the ECS is profoundly modulated by circadian rhythmicity. As an example, CB1 receptor protein is at its highest concentration when AEA levels are lowest and vice versa, whereas the expression of CB2 did not show striking diurnal differences, at least in the rat cerebral cortex.
In contrast, levels of 2-AG, a full agonist to CB1 receptors and about times more abundant in brain than AEA, follow an opposite course. Concentrations are lowest around In rats, an AEA injection before experimentally induced traumatic brain injury significantly increased survival when traumatic brain injury was induced at This suggests that the time of administration of cannabinoids could also modulate effects. Last but not least, nutrition also plays an important role in palliative care.
Some pathways of their degradation produce, among others, proinflammatory compounds. A recent study found that 2-AG plasma levels were significantly reduced by a diet high in omega-3 and low in omega-6 fatty acids H3-L6 intervention , which in turn significantly decreased severity of headaches.
In summary, the endocannabinoid system is likely playing a crucial role in palliative care. The future will show whether an optimized treatment strategy with cannabinoids can also prolong life of brain tumor patients by their virtue to combat cancer cells.
