What is The Endocannabinoid System?

In the early 1990s, the endocannabinoid system (ECS) was found by scientists who were conducting research into THC, the most well-known cannabinoid. The ECS is a complex cell-signalling system within the human body – and all mammals for that matter. Cannabinoids are chemical compounds that can be found in the cannabis plant, hence the name.   Scientists are still working hard to get a full understanding of what the ECS is and how it works. But from what we have gathered so far, we know that it plays a role in the regulation of a wide variety of functions and processes within the body, including the following:

  • Mood
  • Sleep
  • Memory
  • Appetite
  • Fertility and reproduction

Even if you do not use cannabis, the endocannabinoid system is still there and functioning in your body. It works in conjunction with the cannabinoids that we produce naturally within our bodies – the endocannbinoids.


What is The Endocannabinoid System?

The ECS is a biological system within the body that helps regulate and maintain homeostasis. It is composed of cannabinoid receptors and endocannabinoids, the cannabinoid compounds that are created naturally by the body.

Cannabinoids are the collective name given to all the chemical compounds that contribute to communication and connection between cannabinoids receptors within the body and the brain.

The ECS is critically important to both the function of our immune systems and our central nervous system. According to research, it controls approximately 15 of the body’s most important functions, including the ones we have listed above.

You can increase the amount of control you have over your endocannabinoid system in one of two ways. You can enhance the effects of certain natural activities, such as eating meals, exercising, and engaging in stress-relieving hobbies such as meditation or yoga; alternatively, you can consume cannabinoids that are derived from plants – phytocannabinoids. Cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC) are two of the phytocannabinoids that you have probably heard about.


These are the cannabinoids that are naturally produced by our bodies. These cannabinoids may be produced in varying quantities in different people, who may also have a surplus of deficiency of them.


These are the cannabinoids that are found naturally in plants. There are many different kinds of plants in which they are found, yet, the majority of people today identify the term with the cannabinoids that are derived from the cannabis plant. The phytocannabinoids CBD and THC are the most well-known and popular of these compounds.

How Was CBD Discovered?

Because of the recent surge in the popularity of CBD use, many people around the world are becoming curious as to who first discovered CBD. People are generally under the impression that CBD has been a relatively new discovery because of this recent surge in popularity; however, the truth is that CBD and how it works within the ECS was discovered more than half a century ago.

Roger Adams, a Harvard University graduate who extracted oil from cannabis to TiVo without knowing what he was doing, was the first to discover CBD in the 1940s. After several years, Adams and other scientists realised that they had extracted another chemical compound from the cannabis plant, which sparked the initial research into CBD.

Adams’ work was simply the beginning of CBD research and is sometimes overlooked as recent research. Dr. Loewe made further significant advances in CBD research in 1946 when he began performing tests with lab animals and CBD, and demonstrated the CBD does not have the intoxicating effects like its main companion, THC. About the same time, another doctor found out how CBD was made at the molecular level, which gave him the nickname “The Grandfather of Cannabis”. This doctor was Dr. Raphael Mechoulam.

How is CBD Extracted?

Making ‘cannabutter’ from cannabis or hemp is a straightforward way to extract cannabinoids for the common user. However, there are two basic methods for efficient molecular CBD extraction for large-scale manufacturing and isolation of each cannabinoid.

Carbon Dioxide:

The CO2 method employs both the gas and the liquid states of the gas. A closed-loop extractor is a pressure chamber that squeezes CO2 gas until it turns into a liquid. The liquid is pushed over the cannabis material, removing cannabinoids such as CBD. The whole solution is brought back to temperatures and pressures where the CO2 turns into gas and evaporates, leaving behind the CBD from the cannabis plant.

Solvent Extraction:

A closed-loop system is also used in this process, in which liquid butane, propane, or ethanol washes over the cannabis, releasing CBD, other cannabinoids and terpenes. Then, the solvent must be carefully heated or cooled in order to get rid of it without damaging the compounds that were removed. The biggest problem with solvent extraction is that some solvents can pull impurities out of the cannabis plant material. This can make the end product unpalatable.  Once the CBD has been extracted, it undergoes a process called “winterisation”. This process removes impurities and undesirable materials such as fats, lipids and waxes that made it through the extraction phase. Winterisation, in essence, converts crude oil into pure oil. The technique takes its name from a process in which the extracted oil is mixed with ethanol and then frozen. Impurities and unwanted compounds harden and fall out of the solution, which is then filtered to separate wax, lipids and fats from the oil. The last step is to remove the ethanol from the solution.   The CBD products that we sell here at CannaBloom for ingestion are all CO2 extracted and compliant within UK CBD laws – this gives our customers confidence that they not only taste great and are free of nasty chemical, but are completely legal to purchase and consume.
