Most CBD oils are available in round-number concentrations such as 250mg, 500mg, and 1,000mg. While these strengths accommodate many CBD users, they may not be sufficient for those with preferences that fall outside round numbers. NuLeaf Naturals offers a less conventional selection of concentrations: 240mg, 725mg, 1,450mg, 2,425mg, and 4,850mg. This range ensures that most users will find a strength that works for them.

Since marijuana is illegal on a federal level, but legal on a state-by-state basis, growers and cannabis businesses cannot legally transport cannabis products across state lines. Some companies that make CBD products — usually supplied in the form of lotion, oils, and pills — have done so anyway, based on the claim that CBD derived from hemp can be classified as botanical extract and a dietary supplement. But over the past few years, the FDA has issued numerous “cease and desist” letters to companies produce cannabis products warning them not to make health-related CBD claims and making clear that it does not consider CBD a dietary supplement.


There’s also been a lot of talk lately about “microdosing” CBD. This refers to an incremental process of finding your minimum effective dose. You can do this with any concentration of CBD oil, but lower concentrations will take longer. In a 2017 article in Rolling Stone, Dr. Dustan Sulak outlines his protocol for microdosing. You can begin this process by asking yourself three questions:
In the United States, over three million people suffer from epilepsy – 470,000 of those people are children. Epilepsy is a disorder of the brain that causes seizures – of which there are over thirty different kinds, ranging from mild and infrequent to life-threatening. Not surprisingly, people with epilepsy face significant challenges – from the cost of healthcare to work limitations and social isolation.
In this edition of Cannabis Conversations, Project CBD Director, Martin A. Lee, discusses the benefits of CBD, the "entourage effect" and the microbiome with Dr. Ethan Russo. A neurologist, scientist, and widely published author, Dr. Russo is currently the director of research and development at the International Cannabis and Cannabinoids Institute in Prague (www.icci.science).
This is great news for hemp farmers and consumers interested in CBD, an industry that’s predicted to hit $22 billion by 2022. However, the CBD market has all the makings of a wild west show, with many businesses anxious to get in on the action and make a tidy profit. As such, you’re likely to see CBD-infused products with prices all over the map. And with no official system of checks and balances, it will be hard to tell how much CBD is actually present or what quality it is.
If medical marijuana is illegal in a given state, THC levels determine whether a CBD product is illicit or not. In most places, the limit is extremely low. We’re talking under 1 percent THC, with some states opting for a cap as low as 0.3 percent. In this case, the only source that would work is hemp, and CBD products will, therefore, be hemp-derived.
Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses.[22] Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects.[23] Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.[2]
And the products on the shelf aren't all the same, Ward said. "There can be many, many different varieties, and if you're thinking about doing this for medical reasons, you want to find a trusted source and do your research," she said. "Where does that oil come from, and how confident can you be that you know the exact percentages of the different cannabinoids in the product?"
To be fair, the paucity of data about CBD’s efficacy and safety in part reflects the federal government’s irrational restrictions on cannabis research. Because cannabis is classified as a Schedule 1 drug, you need a license from the Drug Enforcement Administration to research it and, until two years ago, you could use only the cannabis grown at the University of Mississippi.
If CBD-dominant products alone are not enough to treat a particular case, products with a higher ratio of THC are sometimes recommended to better manage pain. For day use, more stimulating, sativa varieties with higher concentrations of myrcene could be added to the formula. In general, for pain, and especially for evening and nighttime, indica strains are favored for their relaxing, sedative effect. A person without experience with THC should use caution and titrate slowly up to higher doses. Research as well as patient feedback have indicated that, in general, a ratio of 4:1 CBD:THC is the most effective for both neuropathic and inflammatory pain. Each individual is different, however—for some, a 1:1 ratio of CBD:THC can be more effective, and others prefer a high-THC strain when it can be tolerated. Each patient’s tolerance and sensitivity will differ, and through titration the correct strain and ratio combination can be found.

Cannabinoids, including cannabidiol (CBD), work by mimicking natural endocannabinoids like anandamide (described above) in the body. Endocannabinoids are part of a complex messaging system in the body called the endocannabinoid system. The endocannabinoid system oversees or regulates parts of the nervous system, endorphins, immune system functions, hormones, mood and emotions, metabolism, and many other chemical messengers in the body.
Now, with the passing of the new 2018 Farm Bill, hemp and hemp-derived products have been officially removed from the purview of the Controlled Substances Act, such that they are no longer subject to Schedule I status. Meaning that so long as CBD is extracted from hemp and completely pure (without any THC — something the DEA doubts is possible) and grown by licensed farmers in accordance with state and federal regulations, it is legal as a hemp product.

Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[24][25] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[26] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[27]
Hi, I had ovarian cancer stage 2 and went to do chemotherapy for 16 times in 2014. It came back last year 2016 but I did not do chemotherapy or radiation therapy as suggested by the doctor. I am taking hormone therapy at the moment. I would like to use cannabis oil but which one and how much CBD and how much THC should I take for ovarian cancer? Can anyone give some idea?. Thank you very much.
Because CBD oil products are mostly unregulated, there’s no guarantee that any given product contains a safe or effective level of CBD. In fact, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are incorrectly labeled, and could cause serious harm to consumers. Some CBD oils may also contain incorrectly labeled amounts of THC and other compounds.
I was diagnosed with vasovagal syncope and in April began have seisures and black outs multiple times a day. I began taking CBD oil on September 1st. Within a week or so I stopped blacking out as often and came to faster. By the end of September Id switched to your product because of the purity. A HUGE IMPROVEMENT Ive been using your 1000 mg bottle for 6 weeks now. Im taking less in the morning and evening. I no longer need a mid day dose. As the weeks go by Ive had no black outs no seisures in several weeks. My energy level has improved my chest pains have gone away. My panic attacks have gone to next to nothing. Ive been able to clean and go out again. Thank you for giving me my quality of life back again. It surely beats taking prescription drugs and dealing with side effects. Only side effects Ive noticed was I stopped sweating profusely everyday and my appetite has decreased and Ive lost a few pounds. YEAH

CBD has been in the news before, as a possible treatment for epilepsy. Research is still in its early days. Researchers are testing how much CBD is able to reduce the number of seizures in people with epilepsy, as well as how safe it is. The American Epilepsy Society states that cannabidiol research offers hope for seizure disorders, and that research is currently being conducted to better understand safe use.

Let’s take a good look at the claim, which is based upon the underlying premise that hemp acts as phyto-remediator. Well, yes, it does. All cannabis serves exceptionally well for phyto-remedation purposes. This means that cannabis mops up contamination and can be used to clean up all manner of nastiness. It also means that if it’s grown under less-than-pristine conditions, it carries that nastiness with it when it’s harvested. And, it carries that nastiness with it into products made with it. So, clean sourcing is an especially big deal with ALL cannabis.

In 2016, the Drug Enforcement Agency (DEA) created a new coding category to classify “marihuana extracts” like CBD, but in doing so made clear that CBD was still classified as a Schedule I drug and therefore still illegal. Although the 2018 FDA approval of Epidiolex meant that the DEA removed this specific CBD drug from Schedule I classification, all other non-FDA approved forms for CBD remained classified as Schedule I drugs.

If you’re taking the oil in liquid form, one dropperful of a low concentration product (100 mg CBD per fluid ounce) will provide about 3 mg of CBD per dropperful — not enough to notice any significant effects. A dropperful of the medium grade product (500 mg of CBD per fluid ounce) will deliver about 15 mg of CBD — a good starting dose. And a dropperful of a high concentration product (1500 mg CBD per fluid ounce) will provide about 50 mg of CBD per dropperful.

Cannabinoids affect the transmission of pain signals from the affected region to the brain (ascending) and from the brain to the affected region (descending). A 2011 study showed that CBD and CBC stimulated descending pain-blocking pathways in the nervous system and caused analgesia by interacting with several target proteins involved in nociceptive control. Authors concluded that the cannabinoids “might represent useful therapeutic agents with multiple mechanisms of action.” [387] The following year, researchers reported that CBD significantly suppressed chronic inflammatory and neuropathic pain without causing apparent analgesic tolerance in animals. [388] And then in 2013, researchers concluded that chronic pain patients prescribed hydrocodone were less likely to take the painkiller if they used cannabis. [389]
There’s also the cost factor: Chronic use of CBD oil can be costly and less effective against microbes compared to alternative antimicrobial herbs like Japanese knotweed, cat’s claw, andrographis, garlic, sarsaparilla, and berberine. The bottom line is, CBD oil is a good option for controlling symptoms associated with Lyme disease, fibromyalgia, and other chronic illnesses, but it should be combined with other antimicrobial and immunomodulating herbs for optimal benefit. CBD oil is best used intermittently to treat symptoms of pain or anxiety, or used chronically only until symptoms gradually resolve, and then discontinued.
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. Refer to cannabishealthindex.com for updated information. Using this rubric and based on eleven studies, cannabis rated in the possible-to-probable range of efficacy for treatment of anxiety.
Our Editor’s Pick is the tincture from CBDistillery. This tincture is available in five strengths ranging from 250mg to 5,000mg, which accommodates a wide range of THC preferences, as well as 15 and 30 milliliter containers. The tincture has a price-point that is slightly below average, making it a good option for value seekers. The tincture, which is non-flavored, routinely undergoes third-party testing to ensure safety and high quality; the testing results are available on CBDistillery’s product pages.
Well, yes and no. "Most companies only search for the cannabinoid THC. That said, there are some testing facilities that check for a spectrum of cannabinoids, and therefore, THC-free CBD products could trigger a positive result," says Sheri Kasper, RDN, LDN. "By law, you are allowed to ask the facility what cannabinoids they test for. If you are uncomfortable with that, you can call and ask anonymously." These super-sensitive tests are rare, however. Most of the time, employers just want to know if you're smoking weed all day, not if you're taking CBD for your anxiety.
It should be noted that recreational use of marijuana (high THC, low CBD cannabis) does result in dependence (but different from narcotics or alcohol, and not as debilitating). Chronic use of THC may be associated with atrophy in certain areas of the brain and reduction of certain cognitive functions (at this point, studies are not conclusive). Interestingly, studies have shown that taking CBD oil regularly can restore areas of the brain that have become atrophied in marijuana abusers.
So is it possible that despite all this anecdotal evidence, low-dose CBD is a placebo? Sure, because, say it with me: We don’t know anything about CBD. “Unfortunately,” says Baron, “we are nowhere near close to having any definitive trials on effectiveness for most symptoms claimed to benefit from CBD with trials that are scientifically relevant, such as prospective randomized placebo-controlled trials.”
But there’s a big difference between the two. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things – it’s good for you, tastes great, and can be used in soap, paint – even as biodiesel fuel. However, hemp seed oil does not contain any concentration of cannabinoids at all, including CBD. So by all means, stock up at your local natural food store. Just don’t expect to reap the benefits of a true CBD oil when you cook with hemp seed oil.
Cannabinoids can be used along with opioid medications, and a number of studies have demonstrated that they can reduce the amount of opioids needed, lessen the buildup of tolerance, and reduce the severity of withdrawal.[384] At least ten randomized, controlled trials on over one thousand patients have demonstrated efficacy of cannabinoids for neuropathic pain of various origins.
Now, many people are understandably flummoxed by a very active campaign to convince the public that CBD is different depending on whether it’s derived from marijuana or hemp.  Hemp and marijuana are both Cannabis. Hemp is Cannabis sativa, and marijuana is either Cannabis sativa or Cannabis indica. Hemp is simply the common and legal term for cannabis that contains less than .3% THC, and marijuana is the common and legal term for cannabis that contains .3% and more THC.
My mom has terminal metastatic breast cancer and her bone metastases are incredibly painful. Not only does this product keep her pain tolerable but it has also decreased her depression and anxiety significantly. She no longer has those ups and downs but finally feels GOOD. Thank you for giving my mom her quality of life back so we can truly enjoy our time with her. For reference she takes 1000 mg 2xday.
While CBD can be extracted from non-hemp varieties of the plant, hemp-derived CBD is less restricted by the government because of its inherently low levels of THC. CBD from hemp is legal for sale in most US states, while CBD products derived from non-hemp varieties can contain noticeable amounts of THC, and are therefore subject to stricter laws and regulations.
Check Dr. Stephen Porges’ work, as well as Stanley Rosenburg. Both treat trauma and the vagus nerve’s role in bodily symptoms, which cause a lot of the symptoms you mention, as well as other people here. Some of Stanley Rosenburg’s simple exercises along with Stephen Porges’ work, can realign the vagus nerve and when done regularly have a cumulative effect. Basically, most symptoms, even seizures can be caused by misalignments and/or contracted muscles, (even the tiniest muscle in the human body, the stapedius muscle when chronically contracted can cause havoc on body) all under the umbrella of the vagus nerve (polyvagal nervous system). This is very well researched and is cutting edge treatment without the use of drugs of any kind. Some of Porges’ treatments use music, believe it or not, specially designed headsets with bone conduction. But please research, there are therapists trained in this field and in meantime, you can self-apply Stanley Rosenburg’s Basic Exercise, as well as others, first and you will see drastic results.
