Biopurus is a small supplier of top-notch, certified organic and high-strength CBD drops using CO2 supercritical extraction, which is the gold standard in the industry. Find out why choosing organic CBD oil is so important. Small is beautiful is a proven statement, because, despite its basic packaging and design, this whole-plant extract is of superb, certified organic quality, and one of the best we’ve tried and tested. Biopurus also produces high-strength drops, following the CO2 supercritical extraction process that is the gold standard in the industry. The highest-quality extract is not only a full-spectrum CBD oil (which contains a full range of cannabinoids) but one that also preserves the raw phytonutrients of the plant: namely, the terpene profile, its bioflavonoids, the chlorophyll and lipids (omega oils). Biopurus believes in preserving the whole-plant organic extract to deliver the full benefits of cannabis oil (without the intoxicating cannabinoid THC).

Their 350 mg CBD is the original broad spectrum oil that started it all for this company. Green Road’s oil is infused with the highest quality pharmaceutical quality naturally occurring cannabidiol. It is a vegetable glycerin based olive oil which is vapeable and sublingual. This powerful oil is American made by an experienced licensed pharmacist. It is quality you can trust.
Although several clinical studies focused on the health effects of CBD, the results available so far were not enough to convince the FDA to approve it as a drug. The FDA does not agree with its use as a dietary supplement either, but as long as sellers publish the appropriate disclaimers (like those on the CBDPure website and labels), it’s not up to them.
Researchers at the Department of Pharmacognosy, The School of Pharmacy, University of London, UK, basis the study conducted on mice found that CBD oil has analgesic properties and may relieve chronic pain of all kinds . It can disrupt the activity of pain receptors in the body and instead cause a release of neurotransmitters such as serotonin and dopamine – “feel good” compounds that can ease discomfort and pain, even if the pharmaceutical painkillers have no effect.
Both hemp and marijuana-derived CBD oil is legal for medical use in 29 states: Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Montana, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island, Vermont, Washington and West Virginia. However, laws on CBD are regularly changing so check with your state.
Transparency: Receptra Naturals’ website has a database where you can look up lab reports for their products. The first time we checked, we got some 404 errors for a couple of the lab reports, but these glitches seem to have been fixed since then. We were able to see third-party lab reports for all their tinctures (though, apparently not for their topicals). 

Hemp Bombs offers high-strength CBD in the following concentrations: 1000mg, 2000mg, and an *insane* 4000mg. This is in addition to their regular strength products (75mg, 250mg, 300mg). These high-strength CBD oils are available as either flavored e-liquid or a flavorless tank additive if you already have an e-juice flavor that you love. If you’re the type of person who needs a high strength product to feel the effects, the 4000mg bottle of e-liquid will be perfect for you. It costs a pretty penny but it lasts an incredibly long time.
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.

When it comes to using CBD, questions keep coming up, especially from people who try CBD for the first time. Since there are different CBD products and because CBD can be used in different ways, the question of how to use CBD oil is quite legitimate.  What CBD products are available, how they can be used, and the bioavailability of each product is covered in this article.


Elixinol is obsessed with creating high-grade CBD oil for the mass market. The company’s leader, Paul Benhaim, has worked all over the globe trying to track down the very best hemp (12). Quality matters to this company, and you can see it in everything they do. They provide a wide variety of 100% organic hemp products in different flavors and strengths. 

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.
Customer Service: We’ve always received fast, informative responses to our queries about products and practices, but there are definitely customers out there who have not. A quick perusal of reviews shows customers who had issues with unaddressed orders. It’s hard to know exactly what the problem is in these situations, but the company’s strict return policy (seven days for unopened products only) probably doesn’t help. It should be noted that the company has a solid base of very satisfied customers as well.
Of course, there is a different side to the story also. It is true that the studies concluded so far have their limitations, and there is no saying what effects supplementation with CBD for more than 6 months could have. However, they suggest cannabidiol has the potential for treating some mental disorders, like anxiety and depression, seizure disorders like epilepsy, insomnia, and chronic pain.
For those customers looking to balance cost and potency, three of our popular brands, RSHO™, Dixie Botanicals®, and Cibdex®, carry a line of CBD hemp oil capsules with a moderate 25 mg of CBD per capsule. These medium potency capsules contain the same CBD hemp oil as our other products, making it simple to take your CBD supplements with you. These bottles fit easily into an overnight bag or briefcase and are never out of place in a bathroom medicine cabinet or office drawer, ensuring your CBD hemp oil supplements are within reach.
The NCBI study does mention some potential side effects for cannabidiol, such as the inhibition of hepatic drug metabolism and decreased activity of p-glycoprotein. CBD can indeed interact with a series of pharmaceuticals, as it inhibits the activity of some liver enzymes called cytochrome P450. This family of enzymes metabolizes most of the pharmaceutical drugs used to treat humans.

CBD derived from marijuana is a different story, and the law varies from state to state. But as long as you’re using CBD oil that contains less than 0.3 percent THC, you have nothing to be concerned about anywhere in the United States. On the other hand, if you want to take your CBD on a trip outside the country, definitely look into local laws to avoid getting into awkward situations while you’re away.
Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.
I recently was a guest at a medical marijuana educational event that highlighted the work of researcher Michael Backes. During his presentation he made a statement about CBD that I have never heard anywhere else that CBD is “regulating” (my word) the effects of THC. I asked the Nurse Practitioner at the event, Ivy Lou Hibbitt of Certicann.com, what he meant by that and she said it was her understanding of Michael’s comment that he takes CBD to reduce the psychoactive effects of THC. Has this property of CBD, that it can lessen psychoactive effects, ever been researched elsewhere?
Simply place the CBD Vape Oil in the designated tank (cartridge), turn on the vaporizer, and smoke the CBD vapor. The great thing about taking CBD vaporized is that it works very fast. The bioavailability is very high, which means that a very large part of the CBD being used is absorbed by the body. The CBD gets into the bloodstream very fast through the absorption in the lungs.
Unlike other CBD oils, PureKana really does excel in CBD oil extractions due to their unique CO2 extraction process which provides a near 99% pure CBD oil. PureKana Natural CBD Oil is an unflavored, dietary and nutritional supplement for increased health and vitality.

And then I woke up on the concrete, a worried crowd gathered around me. “You had a seizure,” my friend said gently as I blinked my eyes, trying to process this new information. I remember it was warm that night because I was wearing a sundress, and when I finally regained consciousness my first worry was that my dress flew up and everyone could see my underwear.
One of the most incredible things about CBD oil is its ability to prevent and stop seizures. Frequent seizures can certainly make life more than a little difficult. Many people with epilepsy have turned to CBD oils. Remember again, CBD is not guaranteed to cure or prevent all health issues, but it has certainly been proven time and time again to provide wonderful benefits.
[…] I have recently partnered with Elixinol through their affiliate program. Elixinol is an online based CBD product company out of Colorado that makes their products from CBD that has been procured from industrial hemp. Elixinol does a wonderful job of being transparent about their product lab results and side effects of CBD. On their site, you can find a great write-up on the side effects of CBD. […]
I started using cbd oil as a tincture to be used under the tongue, and after a two month period (with another brand), I did not feel there was a change in my desire for a product to fight chronic anxiety and osteoarthritis. Being a smoker, who strongly wishes to quit, I visited a vape shop, and was recommended I try mixing KOI 1000mg vape oil and combine that with my preferred menthol flavor and try 1/4-1/3 mixture with my smoke liquid. I agreed to try and in just a few short weeks I have noticed a definite, positive effect in CBD oil use! I have found ability to greatly reduce smoking cigarettes AND reduced anxiety and pain. I believe what I have read about the purity of KOI was the difference, and success comes in the ability to consume CBD throughout the day as I vape, and I am extremely grateful to find someone adept matching the level of what I smoked and level of CBD liquid I had consumed, and match that with new generation easy to use vape equipment with KOI (Summer is my favorite), and menthol which I can consume throughout the day . So find a vape expert, let them know your needs, and try KOI, a truly pure quality product which I hope eases your personal health issues! It’s helping me! KOI is great!
