I ordered this a few weeks ago after we got scammed by another CBD product company. My husband was very leary of trying another product. But today he had left for work ( he transports cars to auction) and came back due to I forgot my drops. He is also mad that I havent placed an order yet and we are almost out. So order is going in for two bottles ASAP for the 1000 mg. This product is well worth the money
When considering our different dietary hemp products, know that they all come in two strengths. Our Original Hemp blends (Hemp Classic, Hemp Complete, & Signature Blend) all have 250+mg of cannabinoids per fluid ounce, and our concentrated blends have 1,500+mg per fluid ounce, six times the potency of our traditional oils. We’ve found that sometimes less is more, but nevertheless, some people like to take very large serving sizes of our hemp extracts.
After seasonal harvests of specific cultivars, these high-CBD hemp crops are put through a specialized solvent-free extraction process to yield a hemp oil that is naturally high in cannabidiol. This pure hemp extract is then tested for safety, quality, and cannabinoid content before being exported to our processing facilities in the United States. Importing any cannabis or hemp product into the United States is a complicated and serious task, so we leave nothing to chance before our high-CBD hemp oil makes its journey across the Atlantic Ocean.
With the increasing hype surrounding CBD, some — including this author — have speculated that it will become the next health fad, like taking fish oil or opting for a gluten-free diet, whether or not the research to support far-reaching health benefit claims pans out (see this recent New York Times op-ed by Cornell Medical College psychiatrist Richard Friedman urging caution). “Big Beverage” companies like Coca-Cola have even been exploring whether they should jump in the ring lest they miss out, bringing CBD infused drinks to the mass market sometime in the not-too-distant future (see my blogpost "Coca, Cola, and Cannabis: Psychoactive Drugs as Beverages").
CBD has some other very important jobs outside of the endocannabinoid system (ECS). For instance, CBD mildly activates one of the brain’s predominant serotonin receptors (5-HT1A), which may explain CBD’s effects on depression and anxiety. It also acts at the peroxisome proliferator activated receptors (PPARs), which halt the proliferation of cancer cells and convey neuro- and cardioprotection. By interacting with a particular PPAR (gamma), CBD could prove to be a promising new way to prevent alzheimer’s disease and other brain disorders.
I really like this company. They had all the criteria that I was looking for after hours and hours of research trying to understand the CBD world. I tried the 1,000 strength for joint pain and inflammation. I noticed great relief within a day or two. I tried a full spectrum next, because I had read that the entourage effect would work better. To be honest, it was about the same. But I returned to Medterra because of the purity of their product and the confidence I have in the company. Medterra is doing everything right, from the carrier oil, to the lab results, and the USA non gmo grown plant. :)
Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD. For a more comprehensive look at these and other studies, visit our medical research and education page.

Can CBD oil help anxiety? Cannabidiol (CBD) is a chemical occurring in cannabis plants. It is possible to add CBD oil to food, and an increasing amount of evidence suggests that it may improve mental health, particularly anxiety. It does not seem to have adverse side effects, but CBD oil is illegal in some states. Learn more about CBD oil here. Read now
“If you use a tiny amount of psilocybin, it still does something,” says Blessing. “Microdosing with psilocybin still has effects biologically, but there isn’t any evidence that low doses of CBD, like 5 mg, do anything at all.” The only study I could find indicating that low doses of CBD have an effect concluded that a rare form of childhood epilepsy called Lennox-Gastaut syndrome is treatable using 10 mg of CBD. For anxiety in adults? Nothing.
One of CBD’s chief properties is its anticonvulsant nature. Clinical trials have shown that CBD is effective at reducing seizures in children, and the FDA is likely to approve Epidiolex, a pharmaceutical-grade version of CBD for this use, in summer 2018. Although CBD has been documented as an antiepileptic since 1881, CBD’s anticonvulsant mechanisms still remain unclear. Not enough studies have been conducted to understand this relationship fully. One possible explanation for CBD’s neuroprotective effects is its interaction with NMDA receptors, which play a key role in the overly active neuron activity that is a hallmark of epilepsy.
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.
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.”  The following year, researchers reported that CBD significantly suppressed chronic inflammatory and neuropathic pain without causing apparent analgesic tolerance in animals.  And then in 2013, researchers concluded that chronic pain patients prescribed hydrocodone were less likely to take the painkiller if they used cannabis. 
Currently on the market are a variety of hemp oil products that are naturally abundant in CBD, including organic hemp oil concentrates, tinctures, capsules, gums, lotions, salves, shampoos, and conditioners. Please visit our online shop to find the right CBD hemp oil product for you! For more information on CBD products, have a look at our comprehensive CBD products list to learn more.
Sativex, an oral spray containing both CBD and THC, can treat MS-induced pain. During one study, researchers gave Sativex to 47 participants with MS. Results were largely positive. Patients who used this spray felt notably better. Their muscle and walking spasms decreased, and they felt pain relief. Thanks to studies such as this one, several countries approved using Sativex in MS treatment.
As noted in the report by Booth, Page, and Bohlmann, various strains of cannabis plants produce terpenes differently. Commonly, hemp plants contain less terpene-rich resin than marijuana plants. The amount of resin found in hemp plants, however, does not affect the quality of CBD that we obtain from them. In fact, hemp plants are a far better source of CBD than marijuana plants.
We also rated the product based on the type of CBD they used: isolate, full-spectrum decarb, broad-spectrum, or distillate. There’s a lot of debate around what is actually best, but our first decision was to give points to CBD oil that contains a range of cannabinoids. While there are certainly people with good reasons for choosing an isolate, there’s a lot of good evidence that CBD works better in combination with other cannabinoids (this is called the “entourage effect”).
A 2016 literature review indicated that cannabidiol was under basic research to identify its possible neurological effects, although as of 2016, there was limited high-quality evidence for such effects in people. A 2018 meta-analysis compared the potential therapeutic properties of "purified CBD" with full-plant, CBD-rich cannabis extracts with regard to treating refractory (treatment-resistant) epilepsy, noting several differences. The daily average dose of people using full-plant extracts was more than four times lower than of those using purified CBD, a possible entourage effect of CBD interacting with THC.
100% organic quality is all we deal. Only select, organic growers and extraction processes are used in any product found here. Our pure CBD oil products and tinctures get to work quickly through direct, oral administration. As a capsular, daily supplement, we also have some of the best in quality CBD supplements for the easy, daily maintenance option. For those that prefer vaping, we are also proud to feature an entire line of 100% organic CBD oil vaping products including dab oils, vape oils, and even high quality vape kits.
Lipid-based extraction: This method uses fats such as organic coconut oil to absorb and encapsulate the plant’s chemical compounds. The upsides of lipid-based extraction are that the fat helps make the CBD more bioavailable (easy to absorb), and there are no harsh solvents used. The downside: you won’t get a full spectrum of compounds like you would with vapor distillation or CO2 extraction.
Last year, the National Academies of Sciences, Engineering and Medicine released a nearly 500-page report on the health effects of cannabis and cannabinoids. A committee of 16 experts from a variety of scientific and medical fields analyzed the available evidence — more than 10,000 scientific abstracts in all. Because so few studies examine the effects of CBD on its own, the panel did not issue any findings about CBD specifically, but it did reach some conclusions about cannabis and cannabinoids more generally. The researchers determined that there is “conclusive or substantial evidence” supporting the use of cannabis or cannabinoids for chronic pain in adults, multiple sclerosis-related spasticity (a kind of stiffness and muscle spasms), and chemotherapy-induced nausea and vomiting. The committee also found “moderate” evidence that cannabis or cannabinoids can reduce sleep disturbances in people with obstructive sleep apnea, fibromyalgia, chronic pain and multiple sclerosis, as well as “limited” evidence that these substances can improve symptoms of Tourette’s syndrome, increase appetite and stem weight loss in people with HIV/AIDs, and improve symptoms of PTSD and anxiety.
The U.S. Department of Health & Human Services also recommends that consumers should be aware of any active ingredients that dietary supplements may contain. An active ingredient of a substance is any component that produces a biological or chemical effect on the body. Our products do contain active ingredients. The most abundant active ingredient in our supplements is the CBD in our hemp extract.
Flower Power, which sells CBD-infused coffee to cafes like Caffeine Underground in New York City, puts 5 mg of CBD in each serving of coffee. The company, like many involved in the sale of CBD, is extremely careful about what it says regarding CBD’s effects for fear of FDA intervention. The standard language for CBD packaging and website documentation is similar to that of many supplements (think: milk thistle, echinacea, elderberry, turmeric) and is some variation on: “These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease or ailment.”
With hemp’s legalization, CBD is bound to become even more visible. Its legal status remains unclear — the Drug Enforcement Administration classifies CBD as illegal, although it doesn’t go after anyone using or possessing it, and it hasn’t said if it will reclassify CBD now that hemp is legal. The Food and Drug Administration still considers it a drug, and therefore categorizes it as illegal to be put in foods and or health products without its approval. After the hemp legalization bill passed, FDA Commissioner Scott Gottlieb issued a statement saying that the FDA’s opinions had not changed, and that CBD companies must obtain approval from the FDA.
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. In 2009 researchers concluded that there was substantial evidence pointing to endocannabinoid signaling as a target for the pharmacotherapy of depression. Authors of a 2016 study wrote that “CBD could represent a novel fast antidepressant drug, via enhancing both serotonergic and glutamate cortical signaling through a 5-HT1A receptor-dependent mechanism.”
We’ve systematically sought out cannabinoid and terpene-rich hemp cultivars for our CBD oil ingredients. We always test for purity and potency with third-party laboratories because safety is paramount to Bluebird. Hemp, because of its innate ability to thrive easily, doesn’t require pesticides (the aromatic terpene compounds in hemp can actually act as natural pesticides), fertilizers, or herbicides in its cultivation, and requires much less water than standard commercial farming. All of our hemp is grown and processed in the USA using organic methods.
NuLeaf Naturals CBD oil tinctures are all full spectrum; it is 100% organic and never made with herbicides, pesticides, or chemical fertilizers. The brand offers a full spectrum pet CBD oil tincture, as well. NuLeaf Naturals offers free shipping to all 50 states; the brand’s products are also sold in more than 1,000 retail locations across the country.
Even though, thanks to the Farm Bill, hemp lost its status as a Schedule I drug – one that has no proven medical purpose and potential for abuse – marijuana did not. That means even though many states have legalized its use, the federal government still considers marijuana and CBD products derived from marijuana in almost any form to be illegal. But so far, federal law enforcement officials have not used their power to swoop in and shut down marijuana operations in states that have legalized it.
CBD oils may contain some THC. Cannabis may impair your ability to drive safely or operate equipment and may have short- and long-term effects on your memory, attention, mood, heart rate, and mental health. It is also easy to overconsume CBD oil, so it's important to start with a low dose, as it may take several hours or longer to begin to feel the effects after consumption.
Here’s where things can get confusing. With increasing legalization of cannabis and cannabinoids, more and more states have legalized cannabis and its constituents including THC and CBD for either medical or recreational use (several states have specifically legalized CBD products, but not THC or cannabis in general). But the federal government has held firm, keeping marijuana illegal as a Schedule I drug (defined as having no accepted medical use in the US, a lack of accepted safety for use under medical supervision, and a high potential for abuse) per the Drug Enforcement Agency’s classification of controlled substances.
This is true despite the fact that unlike marijuana, hemp contains only trace levels of THC (tetrahydrocannabinol), the chemical component that gives marijuana its euphoric qualities. Instead, hemp is primarily known for its fibers, commonly used to make rope, fabrics, auto parts, industrial materials, and a variety of other products. Hemp is also known for its highly-nutritious seeds (a.k.a. hemp hearts), which have been shown to benefit heart health, skin diseases, and more.
Within the cannabis industry, CBD products have become a hot commodity, with some companies using hemp-derived sources to extract CBD in order to stay on the right side of federal law. Just how much CBD is contained in hemp isn’t clear however. There isn’t much in the stalks and seeds of the cannabis plant, but breeders have been developing hemp and marijuana strains with “high CBD” content and extracting CBD from plants in the form of concentrated oils. In states where they’re legal, CBD products are increasingly popular and are often included as an additive to beverages and other food products.
Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain. It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12. Although currently classified as orphan receptors, these receptors are most closely related phylogenetically to the cannabinoid receptors. In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist, and this action may be involved in its antidepressant, anxiolytic, and neuroprotective effects. It is an allosteric modulator of the μ- and δ-opioid receptors as well. The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.
I first encountered CBD while on sabbatical a few years back. As I drove up the Oregon Coast Highway, it was hard to miss all the cannabis shops along the Pacific. I stopped in one, perused the menu, and selected two marijuana specials — Nine-Pound Hammer and Trainwreck — and some CBD gummy bears. The cannabis was, well, as advertised, and the CBD candy, as far as I could tell, was a fruit-flavored placebo.
Could cannabidiol help prevent tumors and other cancers before they grow? A 2012 study showed that animals treated with CBD were significantly less likely to develop colon cancer after being induced with carcinogens in a laboratory. Several studies had already shown that THC prevents tumors and reduces them, including one in 1996 on animal models that found that it decreased the incidence of both benign and hepatic adenoma tumors. In 2015, scientists analyzed the medical records of over eighty-four thousand male patients in California and found that those who used cannabis, but not tobacco, had a rate of bladder cancer that was 45 percent below the norm. Topical products can be used to treat and prevent skin cancers. Continuing research is focused on the best ratio of CBD to THC and the most effective dose level in cancer prevention and treatment.
