Thanks to research and modern technology the cannabis plant is now being processed in numerous ways to help patients from across the world. Patients are able to benefit of it’s cannabinoids CBD and THC in the form of oils. One of those ways is in the form of CBD Oil. To create CBD oil, solvents, such as CO2 are used to separate the cannabinoids (in the form of oils) from the plant material, creating the highly concentrated product.
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.
Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.
It makes no sense to me that something that helps with anxiety has an irritability side effect – as a lot of my anxiety is co-mingled naturally with irritability. Further, I have noticed none of these side effects, given that if you become fatigued or sleepy, you adjust dose the next day. So I don’t call that a side effect – rather – an effect of taking too much.
A newcomer to our CBD oils ranking, RE: Botanicals is no stranger to hemp. Founded by John Roulac, a long-time hemp advocate and founder of the organic superfoods brand Nutiva, RE: Botanicals is one of the only CBD brands to earn the USDA organic seal. They deserve a shout-out for prioritizing regenerative agriculture, while keeping prices reasonable.   
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.
In addition to all the benefits we’ve already discussed, CBD has been proven to have antioxidant and neuroprotective effects. This means that it helps repair the damage from oxidative stress, which is believed to be a primary cause of diseases like Alzheimer’s, Parkinson’s, ALS — even heart disorders and some forms of cancer. This is a hugely beneficial effect of CBD.

A group of 15 patients who received CBD over a period ranging from one month to one year were surveyed to gather various data. The researchers sought information about the patient and the caregiver, changes observed in the seizures, neuropsychological effects, side effects and the family’s overall perception following the use of cannabidiol. This simple observational study identified some very encouraging findings:

Unlike THC, which primarily binds to CB-1 receptors located in the brain, CBD works in the body by manipulating receptors throughout organ tissues, the immune system, the pain response system, the hormonal system, and other whole-body regulatory systems. Basically, since its receptors have been found to exist in virtually every cell and tissue type in the body, CBD is believed to work on every aspect of human health and behavior – from the subcellular level to the whole-body leve and beyond.
“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
Elixinol has a wide range of products, but their CBD Tincture does the trick. It’s the cream of the crop regarding CBD oils and that reflects in its price. One dropper (1mg) from the 300 series contains 10mg of CBD. This allows you to get precise amounts of CBD and no guess work is required. Elixinol has received numerous awards for their products and extraction process.
So when people began touting the benefits of CBD for pain, it was a big deal. A non-addictive substance that can ease pain without making you feel high or groggy? It’s easy to see why CBD has been making so many waves. In fact, cannabis plants have a long history as a pain reliever. Whether or not it’s true that Queen Victoria took CBD-rich cannabis to help with menstrual cramps, it is certainly true that her royal physician, Sir J. Russell Reynolds, listed cannabis as “one of the most valuable medicines we possess.” Victorian doctors aside, there are also ancient Assyrian and Ayurvedic manuscripts that recommend cannabis for pain.
While it is still classed illegal on a Federal level, individual U.S. states have adopted a more lenient policy towards this plant and some states now allow it for recreational use. The easing up of state laws has also allowed researchers to explore this miraculous plant and only recently has it been found to be an effective treatment for a variety of medical problems due to its CBD oil benefits. From cancer, anorexia, pain and inflammation management it seems like medical marijuana is placing a strong footing within the medical industry.
Moreover, a patient survey conducted by Project CBD, declared that “…cannabis appears to be an effective pain management tool with few negative side effects.” The study went on to say that a “…significant decrease in opiate usage among elderly patients while taking medical cannabis [was observed during trial].” In short, it has been portrayed clearly numerous times through valid and well-publicized clinical studies that cannabis is a practical option in terms of efficient pain management.
 This study investigated how CBD could affect subjects with liver injuries resulting from chronic and binge alcohol consumption. CBD was given to subjects (in this case, mice and human blood samples) that had been fed alcohol. In short, the analysis demonstrated that CBD lessened the elevated liver enzymes and the increased liver triglyceride. It also reduced fat droplet accumulation.
Author Gerhard Nahler found it most surprising that an entire group of authors were “tempted to over-interpret results.” However, he felt that misinterpretations are not entirely uncommon, stating “People overlook quite frequently that “in vitro” results may differ significantly from conditions “in vivo”, particularly in man. In vitro results are suggestions, not proofs for processes in real life.”
Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
A group of 15 patients who received CBD over a period ranging from one month to one year were surveyed to gather various data. The researchers sought information about the patient and the caregiver, changes observed in the seizures, neuropsychological effects, side effects and the family’s overall perception following the use of cannabidiol. This simple observational study identified some very encouraging findings:
CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
This is the second time Moon Mother Hemp Company has placed among the top five brands on our ranking. The Colorado-based company, which was founded about a year ago, sets the bar very high for quality (including USDA-certified organic hemp) without charging the moon for its products. Their tinctures taste so good, you may be sad you don’t need more.
