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. Initial research published in the Journal of Alzheimer's Disease found that CBD was able to prevent the development of social recognition deficit in participants.
This means that CBD could help people in the early stages of Alzheimer's to keep the ability to recognize the faces of people that they know. This is the first evidence that CBD may slow the progression of Alzheimer's disease.
Cannabis is legal for either medicinal or recreational use in some American states. Other states have approved the use of CBD oil as a hemp product but not the general use of medical marijuana. Some state and federal laws differ, and current marijuana and CBD legislation in the U. There is an ever-changing number of states that do not necessarily consider marijuana to be legal but have laws directly related to CBD oil. The following information is accurate as of May 8, , but the laws change frequently.
However, state legislators generally approve the use of CBD oil at various concentrations to treat a range of epileptic conditions. A full list of states that have CBD-specific laws is available here. Different states also require different levels of prescription to possess and use CBD oil. In Missouri, for example, a person can use CBD of a particular composition if they can show that three other treatment options have failed to treat their epilepsy.
Anyone considering CBD oil should speak with a local healthcare provider. They can provide information about safe CBD sources and local laws surrounding usage. This is one of more than 80 active chemicals in marijuana.
The new product was approved to treat seizures associated with two rare, severe forms of epilepsy in patients two years of age and older. Many small-scale studies have looked into the safety of CBD in adults. They concluded that adults tend to tolerate a wide range of doses well. Researchers have found no significant side effects on the central nervous system , the vital signs, or mood, even among people who used high dosages.
The most common side effect was tiredness. Also, some people reported diarrhea and changes in appetite or weight. Concerning the product that the FDA approved to treat two types of epilepsy, researchers noticed following adverse effects in clinical trials:.
The patient information leaflet notes that there is a risk of worsening depression or suicidal thoughts.
It is important to monitor anyone who is using this drug for signs of mood change. Research suggests that a person taking the product is unlikely to form a dependency. There is often a lack of evidence regarding the safety of new or alternative treatment options.
Usually, researchers have not performed the full array of tests. Anyone who is considering using CBD should talk to a qualified healthcare practitioner beforehand. When drugs do not have FDA approval, it can be difficult to know whether a product contains a safe or effective level of CBD.
Unapproved products may not have the properties or contents stated on the packaging. It is important to note that researchers have linked marijuana use during pregnancy to impairments in the fetal development of neurons. Regular use among teens is associated with issues concerning memory, behavior, and intelligence. CBD-based products come in many forms. Some can be mixed into different foods or drinks or taken with a pipette or dropper.
Others are available in capsules or as a thick paste to be massaged into the skin. Some products are available as sprays to be administered under the tongue. Recommended dosages vary between individuals, and depend on factors such as body weight, the concentration of the product, and the health issue.
Due to the lack of FDA regulation for most CBD products, seek advice from a medical professional before determining the best dosage. As regulation in the U. After discussing dosages and risks with a doctor, and researching regional local laws, it is important to compare different brands of CBD oil.
There is a selection of CBD products available for purchase online. CBD has been tested and approved for one specific use. Does this mean it is safe and will soon have approval for other uses? The research is emerging to support the use of CBD for numerous conditions, as well as looking closely at safety, side effects, and long-term effects. There are some valid concerns about long-term use that must be tested before CBD can be recommended for other diseases.
As one approach to pain management, it is seen as an alternative option to the addicting narcotics. The use of CBD oil might complement a medical approach to treating physical and mental diseases. It is worth discussing with your doctor. We picked linked items based on the quality of products, and list the pros and cons of each to help you determine which will work best for you.

Highlights of prescribing information: Early phase in the development of cannabidiol as a treatment for addiction: Two hours afterward, subjects were asked to perform the stress tests Timing of the tests was chosen to coincide with peak plasma levels for CBD All the experiments were performed in a sitting position under ambient temperature conditions.
Maximum voluntary contraction for the isometric hand grip test was assessed for each subject prior to administering study medication. After administration of CBD or placebo, subjects remained seated, either doing nothing, reading, or using a computer.
During this time, subjects were connected to a calibrated Finometer Finapres Medical Systems , which uses a finger-clamp method to detect beat-to-beat changes in digital arterial diameter using an infrared photoplethysmograph The Finometer gives a continuous signal of beat-to-beat changes in blood pressure and blood flow, and it uses this signal to derive other parameters, including systolic, diastolic, and mean blood pressure; interbeat interval; heart rate and left ventricular ejection time; stroke volume; cardiac output; and systemic peripheral resistance.
Baseline cardiovascular data was recorded for 2 hours following administration of CBD or placebo. Forearm blood flow was measured using a calibrated laser Doppler flowmeter Perimed After 2 hours, subjects underwent the cardiovascular stress tests in the following order: The mental arithmetic test consisted of calculating a sum every 2 second for 2 minutes.
Subjects were seated in front of a computer screen, and a PowerPoint presentation delivered a slide with a simple mathematical sum of a 3-digit number minus a smaller number e. Cardiovascular parameters were measured continuously using the Finometer, while skin blood flow measurements were taken just before, during, and 5 minutes after each test.
Each stress test lasted for 2 minutes, and there was a recovery period of at least 10 minutes. Data were not unblinded until after statistical analysis. Ten healthy young male volunteers, mean age 24 years range 19—29 , with no underlying cardiovascular or metabolic disorders, were recruited for this study, which was approved by the University of Nottingham Faculty of Medicine Ethics Committee study reference E Written informed consent was obtained according to the Declaration of Helsinki.
Exclusion criteria included any significant cardiovascular or metabolic disorder or use of any medication. All the volunteers were nonsmokers and had taken no prescribed or over-the-counter medication within a week prior to randomization. No volunteers had ever used cannabis.
