CBD Glossary

CBD is one of the most misunderstood compounds in the world, with many people’s bias thinking it must be illegal and bad for you if it’s a cannabidiol. Nothing could be further from the truth.

If you’re reading this CBD Glossary, however, you’re probably new to and intrigued by CBD, and how it is beneficial.

If you’re CBD beginner, it can be hard to get to grips with the terminology. That’s where our CBD glossary comes in: each term is set out in alphabetical order and is accompanied by an easy to digest explanation.


Additive is a substance added to food/drink to improve the taste, appearance or preserve it.


Andandamide is a fatty acid neurotransmitter produced by the body that interacts with the CB1 cannabinoid receptor. These are responsible for mental and physiological processes.


Bioaccumulator is a living organism, such as the hemp plant, that absorbs toxic substances from soil and pesticides.


Bioavailability is the proportion of a substance that enters the circulation, and has an active effect when introduced to the body. For example, if you take 100mg of something and 60mg is absorbed, the bioavailability is 0.6 or 60%. The bioavailability of most CBD oils is between 10-20%.

Broad Spectrum

Broad Spectrum refers to CBD products that contain various compounds and cannabinoids from the hemp plant. These include cannabichromene, cannabinol, and terpenes. Broad-spectrum CBD doesn’t usually contain THC, although some brands might have trace amounts.


Cannabis plant

Cannabis is a psychoactive drug from the Cannabis plant, commonly known as marijuana, weed, skunk, pot, dope or grass.

Cannabis Oil

Cannabis Oil is similar to CBD oil, but it’s extracted from the cannabis plant, whereas CBD oil is extracted from the hemp plant. Cannabis oil is usually high in THC and low in CBD, which again is the opposite of CBD oil.


Cannabinoid are natural comounds found in cannabis/hemp plants. There are over 100 cannabinoids that scientists know of and the two most commonly known are THC and CBD.

Carrier Oil

Carrier Oil is typically plant or nut-based oils that are used to carry and deliver the CBD to the tissues in your body. For CBD products they’re usually made from coconut oil, although some brands use other oils such as avocado oil, hemp oil, and olive oil.

CB1 Receptors

CB1 Receptors are cannabinoid receptors, that form part of the endocannabinoid system that allows humans to interact with CBD. They’re part of the neurological network that effects our appetite, pain-sensation, mood, and memory.

CB2 Receptors

CB2 Receptors are cannabinoid receptors, that form part of the endocannabinoid system that allow humans to interact with CBD. They’re associated with the immune system and they’re known to regulate inflammation.

CBC (Cannabichromene)

CBC is a less commonly known cannabinoid found in the cannabis plant. It has been shown to encourage growth in the human brain by increasing the viability of developing brain cells in a process known as neurogenesis.

CBD (Cannabidiol)

CBD Cannabidiol

CBD is a non-intoxicating cannabinoid found in the cannabis/hemp plants, and it is now said to have many health benefits. CBD sold in the UK can only be extracted from the hemp plant because of its low THC qualities.

CBDa (Cannabidiolic Acid)

CBDa is one of the many compounds found in the cannabis plant and is the chemical precursor to cannabidiol (CBD). Basically, CBD is created when the acid is extracted from CBDa, but CBDa is also said to have many health benefits.

CBD distillate

CBD distillate is highly-purified thick, amber liquid produced when hemp extract is winterized in ethanol and then distilled.

CBG (Cannabigerol)

CBG is another compound found in the Cannabis plant. It’s only recently been discovered and it’s said to have health benefits similar to CBD.

CBN (Cannabinol)

CBN comes from the breakdown of the psychoactive cannabinoid THC after it has been exposed to oxygen, UV light or heat. It's mildly psychoactive, but it doesn't give you a high like THC.


COA stands for certification of analysis. It is a certified document from an accredited laboratory that confirms that a regulated product meets certain specifications.

CO2 Supercritical Extraction

CO2 Supercritical Extraction is a method of extracting cannabinoids. This method uses a very controlled temperature and pressure to extraction process, which separates the constituent oils and removes any unwanted compound, such as THC.


Concentrate is a term used to describe a substance where any diluting agent is either reduced or removed completely, resulting in a higher purity product. In CBD, diluting agents include things like carrier oils and other ingredients.


Decarboxylation is the process in which heat is applied to CBDa to eliminate carboxyl and convert it to CBD.


Edibles are products containing CBD that you eat or drink. Commonly called CBD Edibles come in a variety of products including Gummies, Chocolate, Cookies and much more.


e-Liquids are the liquid found in e-cigarettes. Typically, e-liquid will include Propylene Glycol (PG), Vegetable Glycerine (VG), and food flavourings. Nicotine and CBD can also be added.


ECB System

Endocannabinoids are a protein compound that are naturally produced in the body, and like cannabinoids they bind to CB1 and CB2 brain receptors.

ECS (The Endocannabinoid System)

ECS stands for the endocannabinoid system that exists in the human body, and is designed to help the body balance itself.

Entourage Effect

Entourage Effect is when a group of cannabinoids are found together, which could enhance their efficacy and absorption.


Flavanoids are a phytonutrient found in fruits and vegetables that give them their vivid colours. There are 19 known flavonoids identified in the cannabis plant.


Full-spectrum refers to the cannabinoids and terpenes in the oil produced from the cannabis or hemp plant. Full-spectrum CBD oil contains all of the naturally occurring cannabinoids, which can help with the efficacy of the CBD oil (see Entourage Effect)

Heavy Metals

Heavy Metals are dense metals such as lead, mercury and arsenic among others. They are usually toxic at low concentrations.


Hemp is form of cannabis plant. Hemp contains a very low percentage of THC, which makes it an ideal source of CBD.

Hemp Seed Oil

Hemp and Hemp Seed Oil

Hemp Seed Oil is the oil produced by pressing the seeds of the hemp plant. It is low in cannabinoids such as THC and CBD but high in vitamins and fatty acids, and is commonly used as a carrier oil for CBD products.


Isolate is a purer source of goods as everything else but the product you buy has been pretty much removed. For CBD isolate, all traces of THC, terpenes, waxes, oils and chlorophyll will have been removed.

MCT Oil (Medium Chain Triglyceride Oil)

MCT Oils are chains of fats and are extracted from coconuts, dairy and palm oils and are used in CBD as carrier oils. They are easily digested which makes them ideal as a carrier for CBD oil.

Omega Oils

Omega Oils are fats/oils found in oily fish such as fish, nuts and seeds. They’re well known as being part of a healthy diet and omega 3 and 6 oils are found in hemp seeds.


Penetrability means the proportion of the substance that can be absorbed through the skin to have an active effect on the body. You will see this on CBD skin care products.


Phytonutrients are what protect plants from insects and UV rays, and they also give plants their bright colours. They’re also believed to contain antioxidant and anti-inflammatory properties.


Psychoactive means something that manipulates the central nervous system and affects brain function, causing possible changes in mood, perception and behaviour.


Psychotropic is a substance that has an effect on your brain function.


Sublingual means “under the tongue” and is a common way of taking CBD Oil Tincture. If taken sublingually, it will enter your bloodstream faster than other methods of taking CBD.

THC (Tetrahydrocannabinol)

THC is a psychoactive cannabinoid found in the cannabis plant, and is an illegal cannabinoid that makes you feel high. There are varied strengths of THC in different cannabis plants.


Terpenes are organic, aromatic compounds found in plants, and are what give the cannabis plant its aroma and taste. There are 120 known terpenes and although they won’t make you high, they can affect the brain.


Topical is a method of applying something directly to the skin. This method isn’t designed to enter the bloodstream but instead it focuses on the area it has been applied to, making it good for things like joint pain and inflammation. Topical CBD products include creams, balms, lotions and ointments.

Transdermal Patches

Transdermal Patches are designed to be applied directly to the skin, but these are designed to help deliver medication to the bloodstream.


A Vaporiser is a vape device used to vaporize substances for inhalation.
