As one of the original CBD manufacturers, Green Roads reputation truly precedes them, and their pharmacist formulated manufacturing process is why we selected them as the best quality CBD oil on the market. They offer a range of CBD oil concentrations (100mg, 250mg, 350mg, 550mg, 1000mg, 1500mg, and 3,500mg) all of which allow you to view ingredients and test results from a 3rd party testing facility via a QR code on the box.
It’s also nearly impossible to overdose on CBD. Kind of like water, dark chocolate, and steamed kale, it has an unusually low level of toxicity. In the last 6,000 years, CBD hasn’t killed anyone via overdose, which is particularly impressive when you compare it to non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, Advil and Tylenol, which can wreak havoc on your gut lining, liver and kidneys. Or aspirin (salicylic acid) which kills over 1,000 people every year. Or alcohol, which kills over 110,000 people a year. No one’s ever died from CBD.
Relevant studies in animal models are summarized in chronological order in Table Table1.1. CBD has been studied in a wide range of animal models of general anxiety, including the elevated plus maze (EPM), the Vogel-conflict test (VCT), and the elevated T maze (ETM). See Table Table11 for the anxiolytic effect specific to each paradigm. Initial studies of CBD in these models showed conflicting results: high (100 mg/kg) doses were ineffective, while low (10 mg/kg) doses were anxiolytic [59, 60]. When tested over a wide range of doses in further studies, the anxiolytic effects of CBD presented a bell-shaped dose–response curve, with anxiolytic effects observed at moderate but not higher doses [61, 90]. All further studies of acute systemic CBD without prior stress showed anxiolytic effects or no effect [62, 65], the latter study involving intracerebroventricular rather than the intraperitoneal route. No anxiogenic effects of acute systemic CBD dosing in models of general anxiety have yet been reported. As yet, few studies have examined chronic dosing effects of CBD in models of generalized anxiety. Campos et al.  showed that in rat, CBD treatment for 21 days attenuated inhibitory avoidance acquisition . Long et al.  showed that, in mouse, CBD produced moderate anxiolytic effects in some paradigms, with no effects in others.
Cannabidiol (CBD) is a phytocannabinoid constituent of Cannabis sativa that lacks the psychoactive effects of ∆9-tetrahydrocannabinol (THC). CBD has broad therapeutic properties across a range of neuropsychiatric disorders, stemming from diverse central nervous system actions [11, 12]. In recent years, CBD has attracted increasing interest as a potential anxiolytic treatment [13–15]. The purpose of this review is to assess evidence from current preclinical, clinical, and epidemiological studies pertaining to the potential risks and benefits of CBD as a treatment for anxiety disorders.
Due to the anti-inflammatory properties of cannabidiol, insulin resistance (the chief metabolic problem for patients with type 2 diabetes) is reduced, leading to a better prognosis thanks also to the lower incidence of dead tissue. Ever since the discovery of CBD in the 1990’s, speculation existed to its effect on other types of receptors (not just cannabinoid receptors) which could be manipulated and included in the treatment of some cardiovascular diseases like atherosclerosis. In light of these speculations, researchers at the University of Tel Aviv (walking in the footsteps of the “father” of cannabinoid research, Dr. Raphael Mechoulam) demonstrated a 30 percent blood flow increase in rodents with areas of dead tissue in the heart muscle.
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.
Heart disease is a growing problem today. In fact, it’s the leading cause of death in the U.S. A healthy diet and lifestyle is a top priority for heart health, but CBD oil can also help. According to research cannabidiol reduces artery blockage, reduces stress induced cardiovascular response, and can reduce blood pressure. It may also reduce cholesterol.
At present, we have the following classification of cannabinoids: endocannabinoids (produced naturally in the body, mainly from fatty acid precursors), phytocannabinoids (compounds that have a plant origin, with the cannabis plant being the best-studied source of phytocannabinoids though not the only one), and artificial cannabinoids (created while studying THC, to garner the benefits of marijuana without the recreational component).
Third-party testing: Once a CBD oil is manufactured, CBD oil companies will often submit their products for third-party tests, which are conducted by non-company personnel to ensure the product is safe for public consumption and meets quality standards.CBD oils should always be accompanied with information about third-party tests; best practice is to avoid oils that do not supply these details.
Anxiolytic effects in models used: CER = reduced fear response; CFC = reduced conditioned freezing; CFC extinction = reduced freezing following extinction training; EPM = reduced % time in open arm; ETM = decreased inhibitory avoidance; L-DT = increased % time in light; VCT = increased licks indicating reduced conflict; NSF = reduced latency to feed; OF = increased % time in center; SI = increased social interaction
