Spruce was founded by Tony Spencer, who had a clear mission for his company—give people access to safe and effective lab-grade, hemp-based CBD. Spencer realized that many other CBD oils on the market were low-potency and simply didn’t work. “We have a lot of customers in pain who have wasted money on CBD products in the past that didn’t work for them,” remarks Spruce on their website.

Dr. Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.


Chronic Pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
The interest and preference for botanical remedies such as CBD oil over harsh pharmaceuticals are growing rapidly. You can read scientific research on the promise of CBD Oil at NCBI. While North America is taking the lead legalizing cannabis and hemp the rest of the world is starting to question their stance on prohibition because of the undeniable benefits. While all talk about plant-based remedies may seem very new, using cannabis/hemp tinctures as a holistic remedy is a generations-old tradition. It was very common to use cbd tinctures of cannabis oil in the eighteenth and nineteenth centuries. We are enjoying a renaissance in ancestral health where we are open again to remedies that were all but forgotten about in the mad race to make medicines a pill offered by a faceless often unaccountable corporation.
Given CBD’s reputation as a popular, artisanal remedy, one would think that Epidiolex would command a lot of “off label” attention. After all, physicians often prescribe pharmaceuticals off label to treat conditions that were not the actual focus of clinical trials. But the costly price tag for Epidiolex (more than $30,000 annually) precludes off label prescribing as well as affordable access for tens of millions of Americans without health insurance.
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Scott Shannon, MD, assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”
All of NuLeaf’s hemp plants are grown on licensed farms in Colorado using sustainable and 100% organic farming practices. Nuleaf’s CBD oils are made using whole plant extraction. That means the final product is a full-spectrum rather than CBD isolate. Moreover, NuLeaf doesn’t include any additives like preservatives, emulsifiers, or even flavors so the final product remains in its purest form.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
Hemp-derived CBD products were made federally legal in December 2018 with the signing of the 2018 Farm Bill. However, several states still have laws in place that restrict the sale and possession of these products. Most companies selling CBD oil are shipping to all 50 states. You should consult your local laws or an attorney in your area if you have concerns about legalities.
In response to the FDA’s historic decision, the Drug Enforcement Administration (DEA) announced in September 2018 that it had removed Epidiolex from Schedule I classification, a category reserved for dangerous drugs with no medical value. Henceforth, Epidiolex would be considered a Schedule V drug, the least dangerous designation under the Controlled Substances Act.
NuLeaf only offers one concentration of CBD oil, 50 mg/ml, and the ingredients are as simple as it gets: USDA Certified organic hemp oil and full spectrum hemp extract. NuLeaf essentially has only one product. But this strategy allows them to keep their prices reasonable and offer bulk buying options—you can buy a bottle of NuLeaf CBD oil containing 240 mg total CBD all the way up to 4,850 mg.
Having lived with a progressive autoimmune condition for several years and endured horrible side effects from the toxic drugs with little benefit, vaping CBD has given me my life back after just 8 weeks. It has reduced the inflammation caused by arthritis in my hands and feet significantly and has generally made me feel relatively normal and I’ve now started to reduce my pain meds and hope to be off these in the next few months.
Endoca’s commitment to social responsibility is such that it even has its own non-profit, The Endoca Foundation. This organization takes in the company’s Endoca Institute of Cannabis, Natural Medicine and Sustainability, which acts as a hub for education and research into medical cannabis; it also spearheads a hardship fund designated for those who wish to investigate the potential benefits of CBD oil products for themselves but lack the funds to do so. By purchasing Endoca products, then, as the producer claims on its website, “customers are not only helping to heal others but also the world.” Moreover, those customers can choose from Endoca’s array of skin care products and drops and even its variety of CBD oil chewing gum – all including oil from hemp plants cultivated using the company’s individual seed bank.
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
According to the 4 Corners Cannabis website, co-owners Justin and Brian Jasiewicz have 30 years of cannabis growing experience between them. That expertise gives them the know-how, the company claims, to make sure that the entire production process of 4 Corners’ CBD oil is run correctly – all the way from field to store. And while that may result in products that are a little more expensive than equivalents on the market, there could be room for that to change if enough people lobby for lower prices; 4 Corners, for one, emphasizes that it “[listens] to the demands from [their] customers to better serve them in the future.” Meanwhile, the company makes picking the right product that little bit easier through its innovative labeling. This makes it plain at a glance for potential purchasers to see which of the 4 Corners range are designed to improve mental well-being and which, by contrast, are targeted at those with active lifestyles.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
