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. Refer to cannabishealthindex.com for updated information. Using this rubric and based on twenty-one studies, cannabis rated in the possible-to-probable range of efficacy for treatment of depression.


CBD also blocked reconsolidation of aversive memories in rat [76]. Briefly, fear memories, when reactivated by re-exposure (retrieval), enter into a labile state in which the memory trace may either be reconsolidated or extinguished [97], and this process may be pharmacologically modulated to achieve reconsolidation blockade or extinction. When administered immediately following retrieval, CBD prevented freezing to the conditioned context upon further re-exposure, and no reinstatement or spontaneous recovery was observed over 3 weeks, consistent with reconsolidation blockade rather than extinction [76]. This effect depended on CB1R activation but not 5-HT1AR activation [76].
Summary: Early research has found that CBD oil has the potential to reduce chronic pain, anxiety, depression and acne, and may help those overcoming addiction. Its anti-inflammatory properties may also play a role in lowering the risk of diabetes and cardiovascular disease. It has even shown anti-tumor effects and could be effective in inhibiting the progression of cancer and its related symptoms.
There are new CBD companies coming online every week – these span the range from truly awful to really great. So how to choose the best? The quality of the CBD oil itself is obviously the most important factor – and many companies do take the quality of their products seriously. To reward those companies, we gave more weight to the quality of the product than any other category.

In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.
A study from 2016 worked with 214 people with epilepsy. The study participants added oral doses of 2 to 5mg of CBD per day to their existing anti-epilepsy medications. The study’s researchers monitored the participants for 12 weeks, recording any negative side effects and checking on the frequency of their seizures. Overall, participants had 36.5 percent fewer seizures per month. However, severe adverse effects were recorded in 12 percent of the participants.
Reflecting the next morning, I was most surprised by the fact that I never felt "high" in any way—there was never a moment of It's kicking in; I can feel it now like with pain medications or even anti-anxiety drugs. Considering it takes time, consistency, and the right dosage to experience the full effect, I continued taking the oil once a day for the next six days. Here's what went down.
As you’ve probably already heard, the hemp plant itself is a highly useful plant, and every part of it has been used to make a wide variety of products, including biofuel and medicine. Biofuel made from hemp seeds is far less expensive and more effective than ethanol derived from corn. If there weren’t so many federal restrictions, growing hemp would highly benefit any agricultural state, but unfortunately most states must pay an absurdly high premium to import hemp seeds. And of course, as you’re probably aware, both THC and CBD seem to be immersed in a constant struggle of medical legality that I simply don’t have the time to address in this post.
Instead, CBD acts as an agonist on an entirely different receptor called the 5-HT1A receptor, and this is how CBD actually works as an antidepressant with anti-anxiety and neuroprotective effects. It also serves as what is called an “allosteric modulator” of your opioid receptors, which is how it works to remove pain and reduce the effects of chronic inflammation. Other positive medical effects of CBD (there’s over 60 of them, if you care to read up on them here) are due to increased intracellular calcium release and agonism of another receptor called the PPAR-γ receptor.
The 2014 Farm Bill[73], legalized the sale of "non-viable hemp material" grown within states participating in the Hemp Pilot Program[74]. This legislation defined hemp as cannabis containing less than 0.3% of THC delta-9, grown within the regulatory framework of the Hemp Pilot Program. This has led many to insist that CBD manufactured from hemp, is legal in all 50 states and exempts its oversight by the DEA as a controlled substance[75]. The 2018 Farm Bill is anticipated to provide further clarity regarding hemp regulations[76].

One study comparing the effects of THC and CBD even found that, while THC increased anxiety by activating the neurotransmitters involved in the "fight or flight" response, CBD actually repressed autonomic arousal—or the nervous system response associated with sudden increases in heart rate or respiration. In other words, CBD is ideal for people looking to relax and unwind—not get out of their minds.


But when it comes to pain management, one of the primary uses for CBD oil, deaths from drug overdoses and drug poisoning continue to rise. Deaths from opioid analgesics – one of the most universally prescribed pain management drugs – increased from 4,030 in 1999 to 15,597 in 2009 and 16,651 in 2010. In 2010, 60 percent of all drug overdose deaths (22,134) involved pharmaceutical drugs, and opioid analgesics showed up in about 3 of every 4 of those pharmaceutical overdose deaths. That confirms the predominant role that research has shown opioid analgesics to play in drug-related mortality. Opioids are nasty, brutal drugs with side effects nearly as bad as the conditions they’re taken for, and although deaths from opioids are common, they’re still one of the most turned to bandaids in modern medicine.

Studies in humans, including many of those cited below, have demonstrated that CBD dosage reduces anxiety (once again, compared to the increased levels of anxiety that THC produces), and that when you combine CBD with THC, it takes the anxiety edge off THC. This is due to the action of CBD on 5HT1A and TRPV1 receptors, both of which are involved in mitigating the anxiolytic, panic and fear responses to stress.
Later in the 1990’s, the National Institute on Drug Abuse (NIDA) funded research that had the goal of proving that cannabis is addictive. But instead of identifying any biochemical pathway that could cause addiction, any research defined addiction by the presence or absence of some degree of withdrawal, with no specific parameters for withdrawal actually defined. In other words, if you’re thirsty, this NIDA-funded research could argue that this means you are addicted to water.
CBD is good for more than just your neurological issues. In fact, it can do wonders with your heart and your circulatory system. Naturally, this includes helping to lower your blood pressure. Most doctors agree that heart pressure can cause many other serious heart conditions, such as heart attacks, strokes, and the metabolic syndrome. Therefore, the most natural way to treat your blood pressure might be CBD oil.
Two additional studies in this area were done using CBD oil. In the first one, 214 participants would take 0.9 to 2.3 grams of oil per 1 pound of body weight. CBD successfully reduced seizures by a median of 36.5%. The second study focused on children who suffered from Dravet syndrome. Dravet syndrome is a type of epilepsy that happens in early infancy. Normally high temperatures and fevers trigger it. The results of the second study showed that CBD oil reduced seizures significantly.

Good morning! Reading through your article, I'm completely impressed and thinking of the various clinical applications (that depressed patient, that anxious one, my arthritic knees!) for the CBD's. THEN you talk about your product, the combination of co-factors sounding really great, but the nano-particles alarm me. There is a fair amount of research about the hazards of nano-particles in cleaning and cosmetic products, I'm wary of ingesting them for fear of nano-sized items going afield of where I'm intending them to go.
Later, Queen Victoria’s physician and one of the world’s leading doctors of that era, Sir Russell Reynolds, prescribed medicinal cannabis for the Queen’s menstrual cramps, for which CBD still works fantastically today. When writing about medical marijuana in the first edition of the British medical journal The Lancet, Reynolds proclaimed that cannabis is “one of the most valuable medicines we possess.” Another widely hailed physician at the time, Sir William Osler, used CBD for migraines with excellent results.
I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever. HOWEVER, dosages of over 100mg have never been shown to be an issue, and I personally do 30-60mg per day (if you use the NatureCBD form you can take less because it's far more absorbable).
The first step to finding your correct CBD dosage is getting as much information as you can about the product you’re using. What is the concentration of CBD? Are there third-party lab tests that can confirm that? The CBD industry is still mainly a grassroots therapeutic movement, and as such, largely unregulated. Concentration and purity levels can differ greatly depending on the manufacturing process.  
Stephanie, generally, I have patients take 20 to 150mg a day for sleep +/- anxiety. Start low and go slow. Know the dosages of your product. Usually 2/3 to 3/4 of the daily dose is 1-2 hours before bedtime, and the other portion is upon waking (to improve wakefulness during the day). Other factors such as stress, hormone replacement, other meds & medical conditions, etc. play a role along with individual differences. I own a compounding pharmacy, so we see a lot of unique needs. I can't give more specific advice in this forum, but there is help!
Cannabidiol is a chemical in the Cannabis sativa plant, also known as marijuana. Over 80 chemicals, known as cannabinoids, have been identified in the Cannabis sativa plant. While delta-9-tetrahydrocannabinol (THC) is the major active ingredient, cannabidiol makes up about 40% of cannabis extracts and has been studied for many different uses. According to the U.S. Food and Drug Administration (FDA), because cannabidiol has been studied as a new drug, products containing cannabidiol are not defined as dietary supplements. But there are still products labeled as dietary supplements on the market that contain cannabidiol. The amount of cannabidiol contained in these products is not always reported accurately on the product label.

Cannabidiol also works with anxiety by boosting our own endocannabinoid levels, meaning that we can naturally produce more of the things inside of us that put us in a good mood without needing extra things like CBD. Another interesting side effect of CBD with anxiety is that CBD actually boosts our own natural production of endocannabinoids such as anandamide.
The words of these scientists convey the significance of the endocannabinoid system, first identified by Raphael Mechoulam in the mid-1990s and possibly one of the most important recent discoveries about the endogenous chemical transmitters involved in maintaining health. Endogenous (created naturally within the body) cannabinoids and their receptors are found not just in the brain but also in many organs as well as connective tissue, skin, glands, and immune cells. The list of CBD oil benefits and health concerns treatable by CBD is so long because these receptors are integral to so many bodily systems.
These manufacturers comprehend CBD oils and moreover represent considerable authority in making a pure CBD crystal that is mainly for treating pressure and anxiety. Their CBD oils are produced in Vanilla and Mint flavours, while their organic products hit the spot. Pure Kana Natural CBD oil is an unflavored, dietary and nutritious supplement for expanded wellbeing and energy. Its mainly for unwinding and because of its mixes, it appears to have a quick impact. All items experience research facility testing to guarantee security and intensity and all their CBD oils are Non-psychoactive.

CBD does not appear to have any psychotropic ("high") effects such as those caused by ∆9-THC in marijuana, but may have anti-anxiety and anti-psychotic effects.[10] As the legal landscape and understanding about the differences in medical cannabinoids unfolds, it will be increasingly important to distinguish "medical marijuana" (with varying degrees of psychotropic effects and deficits in executive function) – from "medical CBD therapies” which would commonly present as having a reduced or non-psychoactive side effect profile.[10][59]
Cost is another consideration. Most CBD oils are sold in concentrations of 300 to 750 mg, although this may range from less than 100 mg to more than 2,000. A good indicator of price-point is the cost per milligram. Low-cost CBD oils usually fall between five and 10 cents per mg; mid-range prices are 11 to 15 cents per mg; and higher-end oils cost 16 cents per mg or higher. Given these varying per-milligram costs, a bottle of CBD oil may be priced anywhere from $10 or less to $150 or more.
Grown and extracted from the USA, our quality CBD is fully compliant under the Kentucky Department of Agricultural Industrial Hemp Pilot Program. Our CBD products are legal and shipped to all 50 states and internationally. All of our CBD products contain 0% THC, guaranteed. We utilize a whole plant CO2 extraction that allows us to draw the CBD from the plant material and filter out unnatural substances, maximizing pure CBD concentration. Each and every product that leaves the facility is third-party tested to ensure consistency and quality.
Pure CBD hemp oil can be used directly just like any other nutritional supplement. With the mounting research and positive results from CBD studies showing such health benefits, there have been great advances in the development of cannabidiol oil. These positive results have led to the emergence and development of a wide range of CBD oil products, which gives consumers the opportunity to find the best method, product, and dose for their specific need in a way that best fits their tastes and lifestyle. Newer products include drops, chewing gums, and capsules. Concentrated CBD oil can also be infused into the body and used topically in skin care products.
At first, some people who deal with anxiety are apprehensive about CBD oil because it comes from essentially the same plant as marijuana. Marijuana contains THC, which is the psychoactive compound that causes you to get ‘high’ during use, and can lead to increased anxiety or paranoia. CBD oil is nothing like marijuana, and it does not contain THC at all. CBD oil can actually treat some of the adverse effects of THC.
