What Is CBD Hemp Oil? [Full Guide]

CBD oil has gained a lot of attention in the last few years, exploding into the media and making a splash in the marketplace that’s been impossible to ignore. However, its popularity has risen so suddenly that many people have been left confused by what this wellness product actually is.

This article explores the fundamentals of CBD oil, helping readers understand how the oil is made, how much they should be using, and what the potential benefits of consuming a high-quality tincture are.

Here is our complete guide to CBD oil.

Understanding the Basics: What Is CBD?

CBD, or cannabidiol, is a compound found naturally in hemp. The hemp plant is a variety of Cannabis sativa, which grows naturally across the globe. Of course, most hemp that is harvested for CBD products is grown in controlled agricultural plots or large indoor grow rooms.

Cannabidiol is most abundant in the leaves and flowers of hemp, as opposed to the seeds which contain little in the way of active compounds. Hemp seeds can be incredibly nutritious in terms of protein and omega acid content, but they are nearly void of CBD and other therapeutic phytocannabinoids.

Is CBD Beneficial?

Years of research into CBD and its properties clearly show the benefit of this compound for therapeutic use. CBD interacts with the body’s endocannabinoid system (ECS) to stimulate the production of endocannabinoids, which are cannabinoids that exist naturally in humans. These cannabinoids interact with corresponding cannabinoid receptors, helping to create internal balance and homeostasis.

The ECS is an essential chemical pathway that manages sleep, memory, appetite, pain response, and more. Because of CBD’s impact on this system, people use CBD oil and other CBD products to tackle issues such as poor sleep, aches and pains, and anxiety. However, more research needs to be conducted before CBD’s potential can be fully realized.

How Is CBD Oil Made?

To create CBD oil, manufacturers typically use two main components: hemp extract and carrier oil. The hemp extract, which contains CBD, is first extracted from the plant. This can be done in a couple of different ways. For small-scale production, solvents like butane are used to extract cannabinoids from the plant. For larger-scale operations, most companies opt for supercritical CO2 extraction.

Although it is more expensive to buy the machinery and hire people with the expertise to operate it, CO2 extraction results in a final product that is of the highest quality possible. The process works by heating and pressurizing carbon dioxide until it develops supercritical properties; that is, properties that boast both liquid and gas characteristics.

In this state, the CO2 acts as a solvent and is flooded into tightly sealed canisters packed with the leaves and flowers of dried hemp. Inside the sealed chambers, the CO2 works to “strip” the hemp plant material of its active chemical compounds – including cannabinoids and terpenes.

The result is a thick raw oil extract that is eventually filtered and purified to contain nothing but rich, full-spectrum hemp extract. Lastly, the raw extract is suspended into an inert oil (usually hemp or coconut (MCT) oil) for optimized bioavailability in the human body.

Using CBD Oil Properly

The most common way to take CBD oil is sublingually. Most CBD oils come with a dropper that allows users to place a measured amount of oil beneath the tongue. For maximum absorption, manufacturers recommend holding an oil for roughly 60 seconds before swallowing. This allows the CBD oil to directly enter the bloodstream via capillaries and arteries in the oral cavity.

Of course, there are other ways to consume CBD oil. One such possible way is cooking with it. Since it has a low evaporation point, however, CBD tinctures can rarely be used in the same way as something like vegetable oil. Many people opt to place drops of oil into sauces, drinks, and other foods. This masks the taste of the hemp extract, but it also makes it less potent as the CBD is subject to digestive metabolism – which is not the case for sublingual use.

Side Effects

While CBD is generally well-tolerated, some consumers do experience side effects, especially during their first time using cannabidiol. Side effects can include a dry mouth, lightheadedness, drowsiness, and mild nausea. CBD is not, however, psychoactive – it will not make you feel high. This is because, unlike THC, CBD does not bind directly to cannabinoid receptors in the brain and central nervous system.


CBD oil with less than 0.3% THC is legal in the USA – as long as it has been extracted from hemp (which is now a legal crop under the U.S. Farm Bill). Well-respected brands lab-test their oils to check for the exact milligram cannabinoid content. For instance, here at PureKana our customers can check a specific product’s lab results simply by visiting the product page. Checking these reports is an excellent way to reassure yourself that you are purchasing a compliant CBD oil that contains less than 0.3% THC content.

What Is CBD Oil? (Summary & Where To Find The Highest-Quality Products)

When it comes to choosing the right oil, users typically have three options: full-spectrum, broad-spectrum, and CBD isolate.

  • Full-spectrum: Contains a complete blend of cannabinoids, terpenes, flavonoids, and traceable amounts of THC.
  • Broad-spectrum: Contains a blend of cannabinoids, terpenes, flavonoids, and 0% THC.
  • Isolate: Only contains one cannabinoid, CBD.

Many users choose to use full-spectrum CBD oils, as they believe in retaining the natural chemical synergy of hemp. At PureKana, we feel passionate about recreating nature rather than altering it in our CBD oils. That’s why even our highly potent 5000mg oil is used with a full-spectrum extract.

More than anything, you should always purchase from a brand you trust. Reputable brands offer transparent products, quality manufacturing processes, natural and pure ingredients, and reliable 3rd party lab reports. They also offer a varied range of CBD products and engage in reasonable return policies in the event that customers are not satisfied with their CBD experience.

It helps me sleep. I seem more relaxed (not drunk or groggy) and I do not feel "foggy" when I awake. I sleep deeper and so good. I take half a dropper of oil (300 mg)
