Cannabis oil is becoming more and more popular, but which one to choose?

There are three families of cannabis oils. The purpose of this article is to present them to you and to guide you in your choice according to the extraction method that suits you the most, or the final product that corresponds to your expectations.

Cannabis is a plant with a large amount of molecules, having different properties. In its natural state, the molecules are present on the flowers, but they can be extracted in order to use only part of them. This allows you to focus only on an active ingredient for example or to vary the modes of use. These processes produce a product with a high rate of cannabinoids which is why we dilute them in oil.

RSO oil

The most common method is called Rick Simpson Oil, short for RSO, after its inventor. This inexpensive but reliable method is easily reproducible for individuals which has led to its success. Technically this oil is made to be consumed pure, i.e. undiluted in food oil because it was developed as a cure for cancer. Its inventor, who is seriously ill, is said to have experienced beneficial effects not only on symptoms, but also on tumours. Beware, however, the molecule whose anti-tumor effects are scientifically studied is THC, not CBD, which is illegal in Switzerland.
This is the process we have chosen to make our CBD oil at 10 and 20 CBD.

Manufacturing method

Here we offer a method that allows you to obtain a product containing 50-60 CBD (compared to 50-60 THC in its original version, because we do not use the same plants.)

  1. The raw material, ground cannabis flowers, is immersed in a solvent that is preferably undenatured ethanol, i.e. suitable for human consumption. We do not recommend any other solvent for this process as dangerous advice is present on the internet. In particular, we will prescribe the use of chloroform, with highly toxic residues remaining in the final product, especially for people who do not have adequate laboratory equipment.
  2. Once the mixture is brewed for a few minutes, it should be filtered with a fine, coffee filter-type filter. We have to throw away the raw material.
  3. The result is a translucent but green mixture, due to the chlorophyll present in the cannabis plant. The solvent must be evaporated to keep only the cannabis molecules. This step is particularly dangerous because of the very high inflammation of ethanol vapours, or any other solvent. Because ethanol has a very low boiling point, evaporation is quite rapid.
  4. The product must then be de-carboxy. This process transforms some of the cannabinoids into another molecule with the desired active ingredients. The decarboxylation point depends on one molecule to another, and this step will be done according to the cannabinoid we wish to bring out in our oil. This is how to heat the oil to the desired temperature for several minutes.

Benefits

  • RSO oil contains lots of cannabinoids and does not focus on one. This is called “Full spectrum.”
  • It is the least expensive and most commonly found.

Disadvantages

  • The ratio of the different cannabinoid levels of the final product depends on the raw material.
  • When immersed in the solvent, terpene is eradicated. They play a primary role in taste but have no therapeutic properties.

Supercritical CO2 oil

The name SUPERcritical CO2 refers to a chemical stage where CO2 is between its gaseous and liquid form. The process is relatively similar to the one described above. However, it is impossible to obtain a supercritical fluid machine for an individual and this requires a lot of extensive chemistry knowledge.

Manufacturing method

In this method the GAS-like CO2 is compressed to make it supercritical (neither gaseous nor liquid), and it is this solvent that will be used to extract cannabinoids from the raw material. This state is possible when the pressure is 7.38 MPa with a temperature of 31.1 degrees Celsius. It is possible by precisely varying the pressure and temperature, to extract the different molecules in the cannabis, and to keep, separately, cannabinoids and terpenes, while these are simply destroyed during the process. Rso. This is called splitting.

When the different taps are released, it is common for terpenes to be extracted on one side, and for a material called wax, containing the different cannabinoids, to come out on the other. This thick, full-fat material looks like a crystallized honey. It then goes through a process called winterization in English in order to make it soluble, similar to the result obtained after the RSO method. This process involves immersing the wax in ethanol, and as in the RSO process, to evaporate it in order to keep as a solution only a dark brown liquid. It is common for laboratories working with supercritical CO 2 to purify the liquid by removing chlorophyll. This makes it possible to obtain a perfectly clear oil is pure, containing a very high level of cannabinoids and almost no residue.

Benefits

  • This method using CO2 tablet is good for the environment, and not harmful to health during its manufacture.
  • The supercritical CO2, does not denature the molecules present in cannabis at all and does not alter its taste. It also preserves terpenes, which will then be added to the oil, or other preparations. This allows you to play on the taste of the final product.

Disadvantages

  • Because state-of-the-art equipment is required, the price of the process is higher than for RSO oil.

Isolate oil

Isolate is the result of a chemical process that separated the CBD molecule from other cannabinoids. In pure form, CBD is a white crystal unlike, for example, THC, which is liquid. If you are interested in the insulation process, I advise you to refer to articles in organic chemistry. The base is similar to the first two methods developed; it is about pushing extraction to the extreme and getting rid of all impurities, including other cannabinoids.

The resulting Isolate contains more than 99 CBDs. The amount chosen in food oil must be diluted to achieve a much lower concentration.

Benefits

  • This allows you to have a product that only includes a cannabinoid.
  • Produced as purely as possible.

Disadvantages

  • Does not contain other cannabinoids that have different virtues.
  • The highest price because it involves the same chemical processes as CO2extraction, and other additional steps.
