A to Z of CBD

Posted by World of Hemp on

There are plenty of buzz words associated with CBD. From why people use it and the ingredients used to how it works in your body, we’ve broken down the A to Z of all the terms you’re most likely to trip across. 

A: anti-inflammatory. 

People are picking up CBD for a number of reasons these days. One of the most common ones is due to its ability to normalise how your body regulates pain and inflammation(1). CBD works with your endocannabinoid system to better enable your body to synthesize its own endocannabinoids. Whether it’s for helping your body recover after a hard workout or alleviating some of the symptoms of joint pain. 

B: bioavailability. 

Bioavailability refers to how much of a medicine or supplement your body will absorb. It varies largely due to the way you administer it. When it comes to CBD for example, vaping CBD e-liquids is both the most rapidly absorbed as well as having the best bioavailability. Around 70% of what you inhale will be absorbed by the body within a few minutes. 

C: calming. 

Another common reason people are incorporating CBD into their diet is due to its ability to support normal mood function. By targeting the cannabinoid receptors in your brain that regulate mood, CBD can help regulate stress responses and cortisol levels(2). 

D: dosage. 

Dosage varies significantly from person to person. It depends on their weight, severity of condition and the kind of CBD product they’re using. For a more comprehensive look at how to calculate dosage for your own use, refer to our dosage guide

E: endocannabinoid system. 

The endocannabinoid system is the system in your body that helps regulate things like mood, pain and inflammation. There are receptors spread throughout your brain, gut, skin, immune system and nervous system that synthesize cannabinoids to help maintain normal body function. 

F: full spectrum. 

Full spectrum refers to the kind of CBD product you’re using. If your CBD product is full spectrum it means it will contain the complete profile of cannabinoids (not just CBD) as well as naturally occurring terpenes from the hemp plant. 

G: gummies. 

An increasingly popular way to microdose with CBD is gummies. They’re discreet, make it easy to regulate and stagger out your dose and can be used to supplement your CBD levels between another product like drops or capsules. Generally they’ll come in a 5mg or 10mg dose each and may also contain a daily multivitamin to help support your diet. 

H: hemp. 

Industrial hemp is the plant that CBD is largely sourced from. While it looks very similar to the marijuana plant, hemp is naturally very low in THC while having high levels of CBD. Hemp is legal to grow across Europe and the US which is where much of the world’s hemp crops are sourced from. 

I: isolate. 

If a product is made with CBD isolate, it means the only cannabinoid present is CBD. Unlike full spectrum, there won’t be any other cannabinoids like CBN or CBG nor any terpenes. This form of CBD is often popular with those people who don’t like the herbaceous flavour that full spectrum products can have. 

J: joint pain. 

Due to its anti-inflammatory nature, CBD products are often used by people who suffer with things like joint pain and arthritis(3). When people suffer with joint issues, it’s usually largely due to pressure and inflammation within the joint. When that inflammation is reduced, so is the pain. 

K: key. 

CBD acts as a key to unlocking your cannabinoid system. It connects to the side of your cannabinoid receptors which in turn makes it easy for the cannabinoids in your body to synthesise more easily. 

L: legality. 

There’s often some concern surrounding the legality of CBD. However, so long as a product contains less than 0.2% THC in the UK and Europe and less than 0.3% in the US, it’s legal to sell. Reputable manufacturers of CBD products will have their ranges lab tested so consumers can check the THC levels to ensure they’re of a legal level. 

M: microdosing. 

Microdosing is an increasingly more popular way that people are incorporating CBD into their lifestyle. It involves taking small, regulated doses throughout the day, sometimes up to six to eight times to sustain a constant level of CBD in your system. 

N: non-psychoactive. 

CBD is a non-psychoactive cannabinoid, meaning it doesn’t cause a change in brain function. THC, which is illegal, is the component many people confuse with CBD and is the cannabinoid that does cause a change in brain function. This is why CBD products must contain very low to no THC to be legal for sale. 

O: oil. 

CBD is a fat soluble molecule, meaning it needs to be administered with an oil if taken orally in order to be absorbed. If you’re using CBD in vape liquids, because you’re inhaling it, it doesn’t need to be in an oil suspension to be absorbed by your body. 

P: PG. 

PG is the acronym for propylene glycol. It’s an ingredient used in vape liquids to help carry flavour and is also thinner than the other main ingredient - VG (vegetable glycerin). Typically, CBD needs to be in a high PG base in order to stay evenly mixed. 

Q: queasy. 

If you’re unwell, suffer from motion sickness or are on medication that can make you feel nauseous, CBD may help alleviate some of these feelings. CBD has an antiemetic effect(4), meaning it helps normalise feelings of an upset stomach and make your car journey or course of medication a little easier. If you’re looking to use CBD while taking prescription medication, please consult with your GP first. 

R: receptors. 

Receptors are an important part of your cannabinoid system. They’re spread throughout your body but are most highly concentrated in the brain, immune system and nervous system. Cannabinoid receptors synthesize endogenous cannabinoids (cannabinoids your body makes itself) as well as exogenous cannabinoids (cannabinoids from external sources like CBD tinctures).

S: supercritical CO2 extraction. 

This is the most commonly used method for extracting cannabinoids like CBD from the hemp plant. It’s where hot air is passed over the harvested hemp which causes it to release the oil from the leaves and flowers. It’s then processed to either make CBD isolate or filtered and left as full or broad spectrum CBD. 

T: terpenes. 

Terpenes are found in all kinds of plants but are particularly abundant in hemp. They’re what give hemp its herbaceous fragrance and smell. 

U: under the tongue. 

This is the most common way to apply CBD and is often referred to as sublingual administration. It’s where you drip a few drops of a tincture under the tongue, allowing it to be absorbed into your bloodstream through the mucous membranes in the mouth. 

V: VG. 

VG is the acronym for vegetable glycerin, another common ingredient used in CBD vape liquids. It serves to create vapour and because it’s thicker, it’s usually used in lower concentrations than conventional nicotine containing e-liquids. CBD needs a thinner base to mix properly and VG can cause the e-liquid components to separate. 

W: winterized. 

Winterized CBD is another extraction method used on hemp. It’s where the plant is washed with alcohol to extract the cannabinoids from the plant. It’s a common method used when creating CBD isolate in particular. 

X: Xylitol. 

Xylitol is a sugar alternative and is a commonly used sweetener. It may be found in some CBD edibles to make them sugar free. 

Y: Yellow. 

If you’re using a potent CBD tincture made with a broad spectrum of cannabinoids and terpenes, it’s often naturally yellow in colour. The terpenes are usually what give off this colour so CBD isolate products are more likely to be clear. 

Z: zero % THC. 

While CBD products are allowed to contain up to 0.2% THC and still be sold legally, many are totally THC free. If you’re concerned about trace amounts of THC at all, you can easily find THC free products on World of Hemp. These will have been lab tested to ensure there is none present.
