How It Is Obtained and What Products Are Made With It
CBD or cannabidiol is the main one of the more than one hundred components that can be found in the hemp flower factory. In this way, it is configured as an all-natural product and universally recognized for its amazing properties to improve people’s health.
As with other well-known vegetables such as olives or flax, CBD can be processed to obtain other products that enhance the health benefits of this popular substance by precise extracting technology. This circumstance, known for more than four thousand years, has been extensively investigated and developed today; thus, modern technology has succeeded in increasing the range of products in which cannabidiol is found, as well as purifying and optimizing the complex techniques necessary to launch the finished product on the market.
Among these products (creams, flowers, capsules or balms) CBD flower oil stands out powerfully, a preparation that has progressively gained popularity until it is currently the best-selling product in whose composition we find cannabidiol.
How Is CBD Oil Obtained?
Obtaining CDB oil is a process that combines the tradition of harvesting with the latest technology and allows us to distinguish the following phases.
Cultivation and harvesting: after selecting the hemp flower seeds best suited to its richness in the CBD, it is necessary to carefully cultivate the plant so that it can develop its full potential. At harvest time, at the end of the plant’s flowering period and after removing the leaves (which are used for the production of other products), the stem is left to dry, soaked to soften it and then separated to facilitate its work.
This is the part where the CBD oil is actually obtained; for this we can distinguish three methods:
- Oil extraction: it is carried out using olive oil as a solvent, which is mixed with the vegetable raw material; it is then heated to about 100 degrees for a period of two hours in order to activate the cannabinoids. This method, which is safe and easy, nevertheless produces a scarce oil that is difficult to preserve and is therefore often used for small domestic production.
- Liquid solvent extraction: often propanol, butane or ethanol. These compounds are cooked together with the plant to extract the CBD. After further filtration and solvent removal, the CBD oil obtained is highly concentrated. However, this method can have both processing and environmental risks.
- Co2 extraction: this method, started in the pharmaceutical and cosmetic industry, uses Co2 as a solvent to obtain the oil, once mixed with the vegetable product and after the isolation of the CBD. Co2 extraction is characterized by the fact that it is totally environmentally friendly (since it does not use toxic products) and produces a product of the highest quality. However, this method requires expensive infrastructure and considerable technical knowledge to determine the exact temperature and conditions under which Co2 interacts with plant matter.
Purification and Enrichment
After the previous step, fats and other unwanted compounds are removed, as well as enrichment, that is, the introduction of substances that increase the benefits of CDB oil (terpenes, olive oil or aromas) to produce a finished product, effective and of high value.
Types of CBD-Based Oils
After this complex process we can distinguish different types of CBD oil; the main classification is the one that distinguishes between full spectrum oil (in whose composition all the compounds present in the plant subsist) and isolated spectrum oil (pure CBD oil stripped of all other elements naturally present in the plant).
Related to this, modern research has pointed to the importance of the so-called “entourage effect“; a complex interaction between the various cannabis compounds, so that by creating a beneficial synergy and mutually reinforcing each other, the health benefits of using CBD oil are increased.
