Best CBD Extracts in UK

Dive into the world of CBD extracts, a non-psychoactive component derived from the cannabis sativa plant. Known for its potent CBD level, discreet size and enticing appearance. Discover the power of this potent extract and how it could potentially enhance your well-being.

What is Cannabidiol (CBD)?

Cannabidiol, commonly known as CBD , is an active compound found in the Cannabis sativa plant. Unlike its psychoactive counterpart, tetrahydrocannabinol (THC), CBD does not induce a “high” or any form of intoxication. These properties make CBD a popular choice in the wellness and health industries. CBD can be derived from two sources: the marijuana plant or its cousin, the hemp plant. Furthermore, it can also be synthesised in a laboratory setting. It’s worth noting that CBD is one of the hundreds of components found in the marijuana plant, yet it’s significant for its potential therapeutic benefits.

How is CBD Extract made?

CBD extract is primarily produced through two methods: CO2 extraction and chemical solvent extraction .
CO2 extraction involves using carbon dioxide under high pressure in an extremely cold environment. This process transforms CO2 into a state that has properties of both a gas and a liquid. In this state, CO2 can effectively extract the desired CBD compounds from the cannabis plant.
Chemical solvent extraction, on the other hand, utilises solvents like butane or ethanol to extract CBD from the CBD flower . These solvents dissolve the plant waxes that contain CBD, allowing the compound to be separated.
Hash Caviars only uses the CO2 extraction technique to create our premium CBD products. Our commitment to perfection ensures that only the cleanest and most efficient extraction technique is used in developing our CBD solutions, with an emphasis on quality and purity. “Explore the benefits of CO2 extraction with Hash Caviars for unrivalled quality and natural goodness.”

Distinction between CBD and THC

Cannabidiol (CBD) and tetrahydrocannabinol (THC) are both active compounds found in the Cannabis sativa plant, but they have different effects on the human body.
THC is responsible for the ‘high’ associated with marijuana use due to its psychoactive properties. It binds to cannabinoid receptors in the brain, triggering a euphoria or sense of relaxation. Despite its stigmatisation, THC has medical benefits, including treatment for conditions like chronic pain and depression.
On the other hand, CBD is non-psychoactive and does not induce a ‘high’. It does not bind effectively to cannabinoid receptors in the brain. Consequently, CBD is predominantly used for its potential therapeutic benefits, such as reducing pain and anxiety, without the intoxicating effects of THC.
It’s also worth noting that while both compounds have the same chemical makeup, their atoms are arranged differently, which contributes to their distinct effects. In terms of legality, CBD is generally legal in many countries, while THC is often regulated due to its psychoactive properties.

CBD Wax Extract

Texture: Has a soft, crumbly consistency similar to beeswax or soft butter. Whipping the 
liquid extract during the purging process creates this texture.
The extraction of cannabinoids and terpenes is followed by a purging process to create wax. During purging, the substance is beaten to introduce air, which results in the distinctive texture. This method is based on classic hash making methods.

CBD Crumble Extract

Texture: It has a dry, brittle texture that is easily broken into smaller pieces. The texture is created using procedures comparable to wax but with a longer purging time.
Crumble, like wax, is generated through extraction and purging methods. The lengthy purging time gives to the brittle texture. The method of manufacture derived from traditional hash-making practises.

CBD Crumble Extract

Texture: This material has a rigid, glass-like structure and a translucent appearance. It is one of the finest and most stable types of concentrate available.
Shatter is painstakingly manufactured to reduce agitation during the purging process. This approach yields a glassy, stable form with high cannabis contents. Shatter’s manufacturing processes are inspired by early cannabis extraction research.
Each of these concentrates not only has distinct textures, but also a long history steeped in traditional ways. The progress of extraction technologies has resulted in the creation of textures that cater to the interests and needs of CBD fans.

Is CBD Extract legal in the UK?

Our Ivory concentrate products are certified to contain no Δ9-THC, making this product absolutely legal.
It’s important to remain conscious that while in Europe or the US, CBD concentrates are widely available for smoking and vaping purposes and in general it is produced with that very purpose in mind, in the UK all CBD concentrates are strictly sold for novelty, souvenir or educational purposes only, to lawfully meet the criteria of an exempted product. At the same time, it is generally accepted that CBD products with less than 0.2% Δ9-THC are safe, non-psychoactive and lawful in the UK.
Remember, you must be 18 or older to purchase CBD products in the UK.

Choosing the Best CBD Extracts: Tips and Guidelines

Choosing the best CBD extracts requires careful consideration of several factors. Firstly, identify the type of CBD extract you’re interested in – Full spectrum, Broad spectrum, or CBD Isolate, each offering a unique blend of cannabinoids.
Secondly, brand reputation is crucial. Always opt for brands with positive reviews and third-party lab testing reports available.
Thirdly, consider the extraction method used. Supercritical CO2 extraction is often favored for its ability to preserve the purity of the CBD.
Fourthly, pay attention to the concentration of CBD in the product. It’s usually measured in milligrams (mg) and can vary widely.
Lastly, consider the product’s certification . Products should be compliant with UK’s Food Standards Agency regulations.
Remember to consult a healthcare professional if you’re new to CBD or if you’re using it for medical purposes.

Potential Benefits of Using CBD Extracts

Explore the potential for CBD to offer therapeutic benefits, wellness advantages, and potential mental well-being. CBD is thought to potentially help with pain alleviation by activating receptors and increasing the body’s natural reactions when it interacts with the endocannabinoid system. While research suggests that CBD may aid with anxiety, more research is needed to completely understand its mechanisms. Before introducing CBD into your routine for potential alleviation and well-being, consider the potential benefits and consult a healthcare practitioner.

Potential Side Effects of CBD Extracts

While CBD Extracts are generally well-tolerated, some individuals may experience side effects . These can include:
Drowsiness : CBD may cause a calming effect that can lead to drowsiness in some users.
Gastrointestinal issues : Some individuals may experience diarrhoea or other digestive issues when taking CBD.
Dry mouth : CBD can inhibit saliva secretion, leading to a dry mouth sensation.
Reduced appetite : CBD can affect your hunger cues, potentially leading to decreased appetite.
Nausea : Some users report feelings of nausea after consuming too much CBD.
Interaction with other medications : CBD may interact with certain medications, altering their effects. Always consult a healthcare professional if you’re using other medications.
In rare cases, high doses of CBD may cause liver damage. Be mindful of your dosage and consult with a healthcare professional for advice. 
Hash Caviars is committed to safety and transparency. While CBD has potential medicinal advantages, we strongly recommend that pregnant or breastfeeding women avoid using CBD products unless you’ve consulted a healthcare practitioner. The effect of CBD on pregnancy and nursing, necessitates extensive investigation, and extreme caution is recommended to preserve the health of both the mother and infant.

The Role of Cannabis Oil in CBD Extracts

Cannabis oil plays a crucial role in the production of CBD extracts. Often referred to as CBD oil , it is a compound extracted from the cannabis plant and diluted with a carrier oil like hemp seed oil or coconut oil.
The main role of cannabis oil in CBD extracts is to act as a medium for CBD, other cannabinoids, and beneficial compounds like terpenes. This allows for easy absorption when consumed or applied topically.
Also, the type of cannabis oil used can influence the CBD product’s properties . For instance, oils derived from hemp typically have a higher concentration of CBD and lower THC content. This makes them ideal for those seeking the therapeutic benefits of CBD without the psychoactive effects of THC.
However, the extraction process can affect the compound profile of the cannabis oil and ultimately, the effectiveness of the CBD extract. The most common methods include CO2 extraction and solvent extraction . Both methods aim to extract the maximum amount of CBD and other beneficial compounds from the plant material while leaving behind any unwanted substances. However, CO2 extraction tends to be a preference as it avoids the use of harsh chemical solvents. All of our products are produced using chemical free CO2 extraction.
Lastly, the choice of carrier oil can also affect the overall quality of the CBD extract. Some oils have added health benefits and can enhance the bioavailability of CBD, making it more efficient.
