How is CBD Oil (Cannabidiol) Made?-for the Ageless

hemp field
How is CBD oil made? That is a big question that needs to be broken down. The answers we've found are simpler than you could imagine.

If you’ve ever researched into the benefits of Cannabidiol (CBD) oil, you will likely have encountered some bold claims about how a one company’s product is better, more potent or more naturally manufactured than another. Of course, not all levels of quality are going to ‘as described’, so how do you know when a company states their CBD oil meets the highest standards - that it really is?

Processing hemp making CBDWe could simply follow suit and wax lyrical about how the quality of our CBD products are superior to the rest, but we thought it would be far better to provide a much closer look into how Cannabis is grown and cultivated. By doing so, we will be able to highlight that not all CBD oils are the same and the reasons why.

We want our customers to be as educated on all the facts as we are, as we stand behind the quality of our CBD oil and how it’s made, meaning that we can afford to be as transparent as we need to be, to get our point across.
In this article, you’re going to find out things like:

  • How and where our cannabis plants are grown
  • Why how the plants are grown matters
  • Why gentle is best when it comes to processing
  • The different methods that can be used for extraction
  • Exactly what is involved in the Co2 extraction process
  • Why organic can be far superior and the safest option

Our aim is that by reading to the end, you’ll know exactly what to look for when choosing good quality, naturally produced CBD Oil. Also, that you’ll see precisely how much work goes into making our oil the best there is.

Ready? Then let’s get started…

“There is much that goes into creating high-quality CBD products, even before anything is harvested or processed”.

The Cannabis Sativa L. Growing Process

Hemp Plants Cannabis Crops“Spacing of the Crop”

Traditionally, when hemp is produced on an industrial scale, the seeds are planted extremely close together, which means these very tall (sometimes taller than 10 feet) plants create an almost impermeable canopy as they grow. One natural consequence of this is, is that no other plants, and more specifically no weeds are able to grow beneath the plant. So little light gets through the dense leaves, that nothing can take root and photosynthesise.
(Canadian Journal of Plant Science 2006)

Cannabis CBD hemp plantWhilst this is common practice amongst hemp growers, for the producers of CBD oil, it isn’t ideal. The kind of plants that are abundant in the oils and resins they require for that kind of product. When growing hemp for this kind of end purpose, the preferred method is to allow each plant to have more room in which to spread out. The key element in this equation is the production of what’s known as ‘trichomes’, which are minute stalks that produce the cannabinoids, the active ingredient in CBD oil.

If these trichomes aren’t given the necessary light that simply doesn’t pervade through crops when they’re tightly packed together, then they won’t fill up with the required cannabinoid-rich oil. The hemp farmers that we use employ this method in their manufacturing, which is one of the key reasons why we chose to partner with them.

Cannabis - Seed Type

Cannabis seed typeThe particular genome of seed that the cannabis plant is grown from can also have a significant effect on the quality of CBD oil that’s produced. When hemp is grown for either nutritional or fabric producing purposes, the physical characteristics of the plant can be very different than the one that’s ideal for creating oil rich in cannabidiol.

If the wrong variety of plant is cultivated for use in CBD oil, it will most likely have a certain amount of cannabinoids present in it, but at a much-reduced level. If you’re someone taking CBD oil as a supplement to boost your overall health, you need to know that the product you’re buying isn’t only slightly more beneficial to you than the type used in cooking. Choosing the right seeds is key to ensuring the very highest quality, cannabinoid-rich Cannabis Sativa plants are produced.

Indoors or Outdoors?

Hemp planting indoor vs. outdoorAnother variable of the cannabis growing process is whether the cultivation occurs indoors or out. Throughout history, Nigella Sativa has traditionally been grown outdoors. That was until recent times when its illegality drove those growing it to have to conceal what they were doing.

The advantage of growing outdoors is the lack of need for artificial lighting, significantly reducing the carbon footprint of the process. Indoor growing does allow for greater control of the crop and for all-year-round growing, but it does require a large amount of power to assist cultivation.

The CBD oil we produce will be produced from cannabis grown outdoors from plants that have been bathed in natural sunlight and enriched from natural soil. Our CBD oil has a clean ecological conscience and is produced in the most planet-friendly way possible. We also choose suppliers that handpick their plants and use organic methods of cultivation, which is so important when talking about bio-accumulators like Nigella Sativa, as they are known to draw every available nutrient from the soil.

As you can see, there is much that goes into creating high-quality CBD products, even before anything is harvested or processed.


CBD Oil - The Extraction Process

CBD Oil Extraction ProcessCompanies are opting to use CO2 extraction, due to the fact that process removes all traces of Tetrahydrocannabinol.
By now, we know that CBD oil is something that is extracted from the cannabis plant and there are numerous methods by which this is achieved. Some good, some not so and each will result in a different kind of product.

Let’s look have a look at some of the extraction methods used...

The Butane/Solvent Method

Butane Solvent CBD ExtractionAs the name of the method would suggest, it involves the use of butane, but it can be achieved by using similar hydrocarbons, such as hexane or propane. This processing technique has been in existence since the 70s in the extraction of a range of different oils, including CBD oil and others like corn oil. These solvents are passed through the plant matter, which removes the required oils out and once this part of the process is complete, the resultant oil needs to be put through another step.

The next part involves heating the mixture inside a vacuum, which then evaporates the solvent, thereby leaving just the cannabinoids behind. Whilst this is an effective way to get the job done, it will result in the loss of around 10% of the cannabinoids present and it is one of the harsher ways of extracting cannabinoids from the plant matter, so much so that sometimes chlorophyll and the flavours are also removed along with the cannabinoids, resulting in a greener, more bitter oil.

One of the undesirable effects of this particular method is that it is also used to create what’s known as Hash Oil, which has all of the THC compounds that cause the well-known ‘high’. Also, whilst the heating process does rid the oil of the vast majority of the solvents that are used to extract the cannabinoids, complete removal can never be fully assured. For this reason, it’s always important to buy your oil from a licensed supplier or you could be putting yourself at risk of harm from any remaining toxins.

The Pros of Solvent Extraction

As long as a high-grade alcohol or solvent is used, a reasonable quality of CBD oil can be produced. It’s also quite a straightforward technique that can be performed by pretty much anyone that has the will to do it.

The Cons of Solvent Extraction

The disadvantages of this method lie in the danger of harming oneself either during the process or by ingesting any unintentionally retained toxins. Most solvents are very flammable, so must be treated with extreme care. If you don’t, you could end up doing yourself a great deal of damage.

The Co2 Extraction Method

Carbon Dioxide (Co2) extraction is a process that involves using cutting-edge industrial equipment that removes the required compounds from the raw plant matter harvested from the fields. The process involves none of the harmful chemicals mentioned earlier, which means that no solvent residue whatsoever is left on the finished product. It is considered in the industry as by far the best way of extracting cannabinoids from the raw plant matter. (Eden Labs LLC, 2018)

How Co2 Extraction is Done

CO2 CBD ExtractionFirst of all, the plant material is compressed at a low temperature, which then has highly-pressurised supercritical Co2 passed through it. The ability to vary both the pressure and the temperature during the process is one of the numerous ways that make this method of extraction so much more efficient than other types. Once the ‘sweet spot’ has been found, the specific, required compound is then able to be extracted and held in a reservoir.

This is not the end of the process, however, as the Co2 is then evaporated back into vapour form at room temperature, extracting precisely the compound being sought and no others - including any undesirable residues or solvents. In this state, it is so pure that it exists in a crystalline form, which is sometimes colloquially described as ‘shatter’, as its structure is so brittle. From this point, the compound is ready to be turned into all manner of CBD products, such as edible oils, creams and balms.

Due to the stigma attached to cannabis-based products, many companies are opting to use Co2 extraction, due to the fact that process removes all traces of Tetrahydrocannabinol, the infamous THC compound that induces the high that comes from smoking cannabis.

The Pros of Co2 Extraction

A Gentle, Chemical Free Extraction for Higher-Quality CBD Oil

Co2 is known to be safe for human consumption, illustrated by the fact that it’s used to produce things like fizzy drinks and it has been in use by food companies for decades. The Co2 extraction process is also known to be the most effective way to produce the highest yields of cannabinoids. Another of its major advantages is the purity of the oil that the process creates, with little or no risk of contaminants being present.

The Cons of Co2 Extraction

The equipment required to employ this method is too expensive for any individual wishing to create CBD products. The average cost of the hardware needed often costs in excess of £30,000 and the process itself is on the scientific side of high-tech and we seriously recommend that “You don’t try this one at home, boys and girls!”

“We have left no stone unturned to ensure that the CBD products we supply for our customers are of the very highest quality”

The Oil Extraction Method

Oil CBD ExtractionIf you’ve read our blogs before, you’ll already know that CBD products have been used for centuries and it’s back into antiquity that we go to describe the last method in our list of extraction methods. Dating back to the beginning of recorded time, oil extraction was a method used on a widespread basis by the people of the day.

It’s also a method used by DIY-producers, who make their own CBD oil at home, basically because it is a very simple and gentle way of doing it. Firstly, the raw material must be put through a process of ‘decarboxylation’, which is achieved by heating the plant material, thereby activating the chemicals present in the plant.

Whilst this is an easy way to extract CBD from Cannabis Sativa, the olive oil that the plant matter sits in for upwards of 1½ to 2 hours, cannot be evaporated after the extraction is complete. The resultant oil is much more diluted than with other methods, so much more has to be consumed to ingest the same amount of cannabinoids.

The Pros of Oil Extraction

This method is relatively inexpensive and very gentle, in fact, it is something that you could do at home if you wanted to. As we said before, people have been using this technique for thousands of years and they can’t all be wrong!

The Cons of Oil Extraction

The main reason that this method is eschewed in favour of solvent and CO2 extraction, is that the oil easily perishes, meaning it goes off far quicker. This means that special care has to be taken to prolong its shelf life, which usually involves storing it in cool, dark areas.

Organic CBD oil is Best

Why organic hemp farming is the bestThere are numerous reasons why organic farming is considered the best for consumers and the environment, not least because it eliminates exposure to the pesticides and chemicals in conventional forms of agriculture. Believe it or not, the pesticides used on crops do end up in our bodies and the problem is getting worse.

Official research has recently highlighted that traces of widely used weed killers in the UK were found on a widespread basis in routine urine tests. Even washing the produce we buy doesn’t remove these toxins, as they are actually inside the plants, not on the surface.
(Time Magazine, Oct 2018)

Organic hemp farmingWhen toxins like these are used on crops year after year, their presence builds ever greater, which is why it is so important to use organic methods to ensure that the crops they produce are not going to cause us harm. It’s also what they take out of the soil that can prove so harmful, as healthy soil typically contains between 600 million and 1 billion helpful bacteria, something that crops are often deprived of when the soil contains pesticides.
(The Balance Small Business, Apr 2018)

When armed with all the facts of the damage caused by pesticides, it becomes immediately obvious why we favour organic farming methods. It’s better for you, it’s better for the CBD products we supply and ultimately better for the planet we live on.

Great Stuff.. It seems, you have researched a lot before posting the blog. Thank you for sharing such a important information, as rarely people know this use of CBD. I know about CBD but not aware the CBD can be use in this way as well.
