So....How is CBD extracted? And why does it matter?

The whole process is both an art and a science, and there are several methods out there. But not all methods are equal – the technique used can greatly affect quality. Here, we'll take you through the intricate steps of extracting CBD from hemp, compare different methods, and discuss what to look for when looking for the optimal CBD oil for your cat or dog.


Why Extract CBD? Benefits of CBD for Pets and How Quality CBD Oil Can Help

Cannabidiol, or CBD, is a naturally occurring compound found in the cannabis plant—specifically, in strains of hemp that are low in THC, the psychoactive component commonly associated with marijuana. Unlike THC, CBD does not produce a high and has garnered attention for its therapeutic potential in humans and animals alike.

Hemp Plant vs. Cannabis Plant

The main difference between hemp-derived CBD and cannabis-derived CBD stands in the amount of THC in the final product. When you extract CBD from hemp, the levels of THC are naturally low, while the cannabis plant is much higher of THC by default.

Now, since THC is toxic for cats and dogs, you do not want to go for a cannabis extract since it can be detrimental for your pet. While other compounds in the cannabis plant, like terpenes, have postive health effects, hemp-derived CBD products are safer and are also regulated differently at the state and federal level.

But don't worry, we will address the process to remove THC from an oil extract so that you, or your pet, can enjoy the so-called broad spectrum CBD.


What is CBD and Why is it Beneficial for Pets?

CBD belongs to a group of compounds known as cannabinoids. These molecules interact with a biological system present in mammals called endocannabinoid system (ECS). The ECS plays a vital role in maintaining homeostasis—a fancy term for balance—in the body by regulating functions such as sleep, appetite, pain, and immune response. By influencing the ECS, CBD can help maintain this delicate balance, potentially alleviating symptoms and improving quality of life.

Yet, not all CBD products are created equal. The method through which CBD is extracted from hemp plants greatly influences purity and effectiveness. Contaminants, such as pesticides or solvents, can end up in the final product.


Demystifying Hemp Oil Extraction: The Various CBD Extraction Methods

Quality, surprisingly, hinges on the method used to isolate CBD from hemp. It's where the journey from plant to pet begins, and the chosen methodology can affect everything from the compound's purity to its final concentration.

The Precision of Using CO2 Versus Traditional Solvent for Hemp Extract

The CO2 method is revered for its precision and efficiency. Utilizing supercritical carbon dioxide—CO2 at a state where it exhibits both liquid and gaseous properties—it acts as a solvent without the downsides commonly associated with liquid solvents. When passed through hemp in carefully controlled conditions of temperature and pressure, CO2 pulls cannabinoids, terpenes, and other beneficial compounds from the plant material.

This method is particularly favored because it allows for the extraction of a clean, high-concentration CBD without the use of harsh chemicals. Moreover, the supercritical CO2 can be recycled and reused in a closed-loop system, making it an environmentally conscious choice.

The Role of Ethanol: Pros and Cons

Another popular method uses ethanol, which involves soaking the plant material in the solvent to strip away cannabinoids and flavors. Ethanol is highly efficient in capturing both water and oil-soluble compounds, making it excellent for full-spectrum extracts.

However, ethanol also pulls out chlorophyll, which may require additional steps to remove due to its bitter taste. Ethanol must be properly purged from the final product to ensure safety and quality, particularly for pet consumption.

Oil Infusion: A Traditional Approach

Traditionally, oil infusion is one of the oldest methods of isolating CBD. It involves decarboxylating the hemp to activate its cannabinoids, then infusing it in a carrier oil at a specific heat to transfer the active compounds into the oil.

While it's considered more accessible for small-scale or at-home extractors, maintaining consistency and purity can be challenging with this method, which might be less suitable for producing standardized therapeutic products.

How Do Different Protocols Affect the End Product Quality?

Knowing how CBD is extracted is crucial, as the compounds isolated and the possible contaminants introduced are directly linked to your pet's response to the product. The various methods are not just a matter of efficiency; they're about ensuring the utmost quality and safety for your beloved pets. By familiarizing yourself with these processes, you become equipped to make better choices, advocate for your pet's health, and foster a deeper bond through the care you provide.

Purity is paramount because it ensures that your pet is getting the beneficial cannabinoids without harmful contaminants such as pesticides, heavy metals, or residual solvents. The purity of CBD is determined by numerous factors, from the growing conditions to the extraction process and post-CBD refinement.


Hemp Cultivation: The Groundwork of Purity

It all starts with the hemp plant itself. High-quality CBD is derived from plants that are grown organically, without the use of chemical pesticides or fertilizers, which can remain in the final product and potentially harm your pet. Look for products made from non-GMO, organically-grown plants for the highest purity.


CBD Extract Wisdom: Clear of Contaminants

Methods such as CO2 or ethanol extraction can influence purity. CO2 is often preferred due to its ability to filter out impurities. However, no matter the process, it is vital that the final product undergoes rigorous testing.


The Importance of Third-Party Lab Testing

This is where third-party lab testing becomes an indispensable tool. Reputable CBD companies will have their products tested by independent labs that check for cannabinoid content, terpene profiles, and possible contaminants. These tests don't just confirm that the CBD content meets labeled claims; they also ensure that the product is free from anything that could compromise its purity.

Testing results, often referred to as Certificates of Analysis (COAs), should be readily available to consumers—either included with the product packaging or accessible on the company’s website. By reviewing these COAs, you can validate the absence of any potentially dangerous substances.


Navigating the Market: Clarity Amid Confusion

Since there are about a million plus one CBD supplements, it's easy to feel overwhelmed. Yet, by prioritizing purity and demanding lab test results, you uphold the health of your pet. Pure CBD means effective CBD, and with the right knowledge, identifying a pure product becomes a simpler task.

Choosing purity is choosing peace of mind. It's choosing rigorous standards and transparent practices. Most importantly, it's choosing to give your pet the best care possible. As you move forward in selecting a product, let purity be your guide and quality be your expectation.


The Supremacy of CO2 Extraction in Making CBD Oil for Pets

Is the CO2 method truly the gold standard, as many claim? Let's see what makes it stand out and whether it's the best choice for your four-legged friend's CBD supplements.

Why Is CO2 Extraction Considered Optimal?

The use of CO2 isolate CBD is efficient and safe. The process involves subjecting carbon dioxide to high pressure and low temperature to create a supercritical fluid. This state of CO2 has the ability to penetrate plant matter and dissolve compounds like a liquid but can be easily removed like a gas, which leaves behind a pure, potent CBD extract without any residues.

Moreover, the CO2 method is highly customizable. By adjusting the pressure and temperature settings, manufacturers can fine-tune the process to target specific cannabinoids and terpenes, or to exclude unwanted compounds like THC. This level of precision ensures that the final product meets the exact specifications for pets, whether that's broad-spectrum CBD or a more specific cannabinoid profile.

Is CO2 Extraction Really The Best Option for Pet Products?

Many vets and pet health advocates favor supercritical CO2-extracted CBD for its purity profile. Since no harsh solvents are used, there's minimal risk of solvent residues that could harm your pet. The method also preserves more of the natural compounds found in hemp, which can contribute to the entourage effect—a synergy of cannabinoids and terpenes that enhances the overall benefits of the product.

CO2 vs. Ethanol: A Comparison

We've discussed the supercritical CO2 method and its advantages in detail. On the other hand, ethanol extraction is another common method due to its efficiency in extracting a wide range of cannabinoids and terpenes. However, it may also extract unwanted components, such as chlorophyll, which requires additional refinement steps.

While the CO2 method is safe and accurate, ethanol wins points for its ability to produce full-spectrum extracts, which can be beneficial in creating the entourage effect. The primary concern with ethanol is ensuring that all solvent residues are completely purged fromthe final product, as even trace amounts can be harmful to pets.


Hydrocarbon Extraction and Safety Concerns

Some manufacturers use hydrocarbon solvents like butane or propane due to their efficiency and low operating costs. These methods are adept at pulling out desirable cannabinoids and terpenes. However, the major drawback of hydrocarbon extraction lies in the potential for residue if not properly purged, which poses significant health risks.


Comparing Efficiency and End Products

When comparing efficiency, supercritical CO2 extraction tends to offer the best yield and potency. Ethanol can also be efficient but may require more post-processing. Hydrocarbon methods might yield a more flavorful extract due to terpene preservation, but they lag in safety.

The quality of the end product also varies. The CO2 method can produce a pure and potent CBD extract ideal for pets who need consistent dosing. Ethanol and hydrocarbon methods can preserve a wider range of cannabinoids and terpenes, which may be more effective for specific therapeutic uses but require more meticulous processing to ensure purity.


What Does This Mean for Your Pet?

DIY CBD Extraction: Is Home Made CBD Oil Safe?

With an increasing interest in natural remedies, some people wonder: Is it possible to isolate CBD at home? While the interst is understandable (afterall, I am a scientist myself), that's not as simple as it looks.

The Challenges of At-Home Processing

The whole CBD isolation protocol is delicate and precise. Professional methods like CO2 or ethanol extraction require specialized equipment and knowledge of chemistry to ensure purity and potency. At-home methods, such as the oil infusion technique, may seem accessible but often result in a less potent extract and can cause safety concerns without proper handling and testing.

Potential Risks and Quality Assurance Issues

Without the controls present in a professional setting, DIY extracts may contain inconsistent levels of CBD, which can lead to dosing challenges. Additionally, there’s a substantial risk of contamination. Home environments are not equipped to mimic the sterile conditions of a lab, and without third-party testing, there’s no way to verify the safety of the homemade product.

Legal and Regulatory Considerations

Beyond quality and safety, legal issues arise with at-home procedures. The legality of handling and processing hemp plant material varies by location, and some methods, especially involving solvents, could contravene local laws.


Educated Decisions for Pet Owners

For pet owners, the well-being of their companions is paramount. While the idea of crafting your own CBD remedies is appealing, the complexities involved make it a challenging endeavor. Professional methods ensure not only a high-quality product but also one that’s safe and reliable for your pet's consumption.

So, while you might be able to isolate CBD at home, the question is whether you should...and your parents probably told you this a million times when you were a kid...at least mine did :).... Given the potential risks and variables, relying on a professional is often the safer, more responsible choice for ensuring the health and happiness of your pet.


How Do Different Extraction Methods Influence Efficacy?

It's crucial to understand that the extraction procedure can impact your pet's experience with CBD. From efficacy to safety, the process used to draw cannabinoids out of the hemp plant matters more than you might think.

From Hemp Flower to CBD Oil: The Journey of Full-Spectrum CBD

Full-spectrum CBD contains a range of cannabinoids and terpenes that work together, potentially creating a harmonious effect known as the 'entourage effect.' Some report that this might offer more comprehensive benefits for issues like anxiety or joint pain. However, as mentioned before, full-spectrum products contain THC, and THC is toxic for dogs and cats

Isolates, however, provide pure CBD with no other cannabinoids or terpenes. This might be the preferred option for pets with sensitivities or when a specific CBD dosage is needed. The extraction method plays a critical role in determining whether the end product is full-spectrum or an isolate, and ultimately, how it may impact your pet's health.

Bioavailability - Why CO2 is Good?

Bioavailability refers to the proportion of CBD that enters the bloodstream. Different techniques directly influence bioavailability due to how well the extraction protocols preserves the original concentrations of CBD in the plants. This means that if the yield is low, the final isolate will have low concetrations of CBD, and the amount allowed to enter the bloodstram will be minimal.

Bioavailability of CBD

Conversely, the CO2 method can help with maximizing bioavailability since it does not use of heat and preserves the integrity of all compounds found in hemp. Higher bioavailability means a potentially more effective product for your pet.


Safety: A Priority for CBD Products 

Every pet parent's top concern is safety and residual solvents or contaminants are a big no no. CO2 extraction's solventless nature, for instance, means there's less risk of solvent residues that might harm your pet. In contrast, other methods require careful purging to ensure a clean product.


THC Removal Techniques in CBD Extraction Process

If you're considering using CBD for your pet, you've likely read about THC—the psychoactive compound found in cannabis- not being good, yet, some products contain "less than 0.3% THC", while many other don't have any THC in them. ...why? And how is THC removed?

Why THC Removal Is Important

While THC is known for its psychoactive effects in humans, it can be particularly harmful to pets, even in small amounts. It can lead to THC toxicity, causing symptoms like lethargy, vomit, urinary incontinence, and possibly neurological complications. If you are a pet owner, make sure that whatever you use has no THC in it...I think I'll keep repeating this forever!!

The Process of THC Removal

The method used to proces hemp can influence how much THC is present in the extract. For instance, using the CO2 method allows for specific targeting of cannabinoids, which means THC can be minimized right from the start. However, additional steps are often required to ensure that THC levels are appropriate for pet products.

One of the most common methods for removing THC is chromatography, a process that separates THC from the rest of the cannabinoids. It's a precise and effective way to create broad-spectrum CBD, which contains multiple cannabinoids but is THC-free.

How Do I Know If What I Buy Has THC In It?

Whatever CBD isolation procedure is used, the goal is to reduce the THC content to a safe, or zero, level. This is typically verified through third-party lab testing, which should indicate non-detectable levels of THC or a concentration that is within legal and safe limits.

The Importance of Choosing the Right Product

Responsible pet owners will seek out products that have clearly labeled third-party test results. Products marketed as 'broad-spectrum' or 'THC-free' should live up to their names, and even if what you buy is full spectrum CBD, what's on the label needs to be confirmed by lab results. It's always better to err on the side of caution and choose products specifically formulated for pets, which take into account the sensitivity of animals to THC.

By understanding how THC can be removed —and the significance of doing so—you can better safeguard your pet's health and well-being. Selecting products with non-detectable levels of THC, or choosing THC-free options, will allow your pet to enjoy the benefits of CBD without the risks associated with THC.
