I have been selling CBD oil since 2014. That is over a decade of watching this industry grow from something most people had never heard of into a crowded, confusing marketplace where every brand claims to be the best. And after all that time, the one thing that still drives me crazy is how loosely the word “pure” gets thrown around.
Pure CBD oil does not mean isolate. It does not mean THC free. It means exactly what it sounds like: CBD, oil, and if there is a flavor, a natural one. No fillers. No synthetic additives. No cheap carrier oils padded out to increase margins. No artificial flavoring to mask an inferior product. Just hemp extract in a clean, quality base.
I am Denise Chapman, authorized Immunotec Hempworx affiliate since 2014, ID number 3123749. I use Hempworx CBD oil every single day. I have helped thousands of customers over the years find the right product, and I have watched what happens when people buy something that is not genuinely pure. They do not get results. They assume CBD does not work for them. And they give up on something that could have made a real difference.
This guide is everything I know about what pure CBD oil actually is, how to identify it, and why it matters more than any marketing claim a brand can make.
Pure CBD Oil Starts With What Is Not In It
This is where most people get confused, and honestly where most brands fail their customers.
Walk into a discount store or scroll through a marketplace like Amazon and you will find CBD oil products at prices that seem too good to be true. They usually are. What makes cheap CBD oil cheap is almost always what gets added to it. Artificial flavoring to disguise a poor quality extract. Synthetic preservatives to extend shelf life. Filler oils that dilute the actual CBD content down to a fraction of what the label claims. Petroleum based carrier oils that your body cannot properly absorb.
Genuine pure CBD oil has a short ingredient list. For Hempworx, it is hemp extract and organic hemp seed oil. If there is a flavored version, the flavoring is natural. That is it. No paragraph of chemicals on the back of the bottle. No ingredients you need a chemistry degree to understand. Clean, simple, and exactly what it says.
I have been saying this to customers for over ten years and it still surprises people: the fewer the ingredients, the better the product. Purity is not about adding things. It is about leaving things out.
How Pure CBD Oil Is Made, Matters as Much as What Goes In It
You cannot have a genuinely pure CBD oil if the extraction process is dirty. This is one of the most overlooked parts of the quality conversation, and it is where a lot of brands quietly cut corners.
The gold standard for extracting CBD from hemp is CO2 extraction. It uses pressurized carbon dioxide to pull the cannabinoids and terpenes from the plant without leaving any solvent residue behind. The result is a clean, concentrated extract that preserves the full hemp compound profile exactly as nature intended.
Cheaper brands use solvent based extraction methods, typically ethanol or hydrocarbon solvents like butane. Done correctly, these methods can produce a decent extract. Done poorly, which is more common than the industry likes to admit, trace solvent residues end up in the final product. That is not pure CBD oil. That is CBD oil with chemical contamination you cannot see, taste, or smell.
Hempworx by Immunotec uses CO2 extraction on every product. That is not a marketing claim. It is a verifiable fact reflected in their third party lab results, which test not just for CBD content but for residual solvents, heavy metals, pesticides, and everything else that should not be in a pure CBD oil.
Pure CBD Oil Still Comes in Different Types
Here is where I want to clear something up, because this is one of the most common misunderstandings I encounter.
Pure CBD oil is not the same as CBD isolate. You can have a genuinely pure full spectrum CBD oil that contains CBD alongside other naturally occurring cannabinoids, terpenes, and trace amounts of THC under 0.3 percent. It is still pure if the only ingredients are hemp extract and a clean carrier oil. The hemp compounds are all natural and exactly where they should be.
You can also have a genuinely pure broad spectrum CBD oil that delivers those same hemp compounds with the THC completely removed. Still pure. Still clean. Still nothing in it that should not be there.
What makes an oil impure is not the presence of other cannabinoids. It is the presence of fillers, artificial ingredients, synthetic additives, or contamination from poor extraction and poor sourcing.
So when I talk about pure CBD oil, I am talking about oil where every ingredient belongs there, every ingredient is natural, and there is nothing hiding in the formula that you would not want to put in your body.
Full Spectrum Pure CBD Oil
This delivers the complete hemp plant profile. CBD, other minor cannabinoids, terpenes, flavonoids, and trace THC all working together. Many of my long term customers prefer full spectrum because of what researchers call the entourage effect, the idea that these compounds are more effective together than any single one in isolation. I have used the Hempworx 750 Full Spectrum CBD Oil myself for years. It is available in Cinnamon, Peppermint, and Natural. All USDA Certified Organic. All CO2 extracted. All triple lab tested.
Broad Spectrum Pure CBD Oil
This gives you the same rich hemp profile with one difference: the THC is completely removed. It is the right choice for people who need to be completely THC free, whether for workplace drug testing, personal preference, or regulations in their area. The Hempworx 750 Natural Broad Spectrum CBD Oil is one of my most popular products for exactly this reason. Also available in Cinnamon Broad Spectrum.
Both are pure. Both are clean. The choice between them comes down to your personal situation, not quality.
The One Thing That Proves Pure CBD Oil Is What It Claims
Third party lab testing. Full stop.
Any brand can write “pure” on a label. It costs nothing and requires no proof. What does require proof is a Certificate of Analysis from an independent, accredited laboratory that confirms exactly what is in the bottle and exactly what is not.
A proper COA for pure CBD oil will show you the actual CBD content per serving and per bottle, the full cannabinoid profile, THC levels, and test results for pesticides, heavy metals, microbials, and residual solvents. If a brand does not publish these reports, or publishes them but they are outdated, or makes it difficult to find them, that tells you everything you need to know.
Hempworx publishes their lab results and every batch goes through triple testing. That means it is tested at the point of raw material sourcing, during production, and on the finished product before it ever ships. Three separate checkpoints. That level of verification is not common in this industry and it is one of the main reasons I have been selling these products for over a decade.
If you are buying pure CBD oil from any brand, ask to see the COA. If they cannot produce one, do not buy it.
Pure CBD Oil and the Hemp It Comes From
The extract is only as pure as the plant it comes from, and this is where organic certification becomes genuinely important rather than just a marketing badge.
Hemp is what botanists call a bioaccumulator. It pulls compounds from the soil with remarkable efficiency. This is actually why hemp has been studied for environmental cleanup, it absorbs heavy metals and toxins from contaminated soil extremely well. But that same property means that hemp grown with synthetic pesticides, herbicides, and chemical fertilizers will absorb those substances too. They end up in the plant, in the extract, and in the oil you are putting under your tongue.
USDA Certified Organic certification means the hemp was grown without synthetic inputs on soil that has been verified clean. It is a rigorous process with third party verification. It is not a label you buy. Every Hempworx CBD oil product is made from USDA Certified Organic hemp grown on American farms. That certification matters to me personally because I take this product every day and I am not interested in consuming pesticide residue.
Why I Chose Hempworx for Pure CBD Oil and Have Never Looked Back
In 2014 I was looking for a CBD product I could stake my reputation on. I was not interested in becoming an affiliate for a brand I was not prepared to use myself and recommend to my family. I tried a number of products and the difference with Hempworx was immediate and obvious.
The oil was clean. The flavor was natural. The results were real. And the company was doing things that almost nobody else in the early CBD industry was doing: American organic hemp, CO2 extraction, third party testing, transparent labeling. They were operating to a standard that most brands would not catch up to for years.
What I could not have known in 2014 was that Hempworx would eventually become part of Immunotec, a Canadian health sciences company founded by Dr. Gustavo Bounous and Dr. Patricia Kongshavn of McGill University. These are medical researchers with 79 global patents and 45 years of clinical research behind them. Their flagship product Immunocal is listed in the Physicians’ Desk Reference in the United States and has been the subject of over 90 published studies.
That is the company backing every bottle of Hempworx pure CBD oil now. The standards were already high. They have only gotten stronger.
Many of my customers use Hempworx alongside Immunocal glutathione as the foundation of their daily wellness routine. If you want to understand how they work together, read the complete Immunocal glutathione guide.
How to Use Pure CBD Oil
Using pure CBD oil correctly makes a real difference in what you experience, and this is something I spend a lot of time explaining to new customers.
The most effective method is sublingual, which means under the tongue. You place half a dropper to a full dropper under your tongue and hold it there for 30 to 60 seconds before swallowing. This allows the CBD to absorb directly through the mucous membranes into the bloodstream, bypassing the digestive system and delivering faster, more efficient absorption than simply swallowing it.
Start with half a dropper once or twice a day. Give your body a month of consistent use before you evaluate whether it is working. CBD is not an immediate fix for most people. It works gradually as it interacts with your endocannabinoid system, and results build with consistency. The customers who tell me it did not work are usually the ones who tried it for a few days and stopped. The customers who call me back a month later are usually very pleased.
Store your pure CBD oil at room temperature away from direct sunlight. Heat and light will degrade the quality of the extract over time.

What Pure CBD Oil Is Not
I want to be direct about this because there is a lot of confusion in the market.
Pure CBD oil is not a medication. It is a wellness product made from hemp, and while I have seen it make a genuine difference in the lives of many customers over the years, I do not make medical claims and I do not recommend anyone use it as a substitute for medical treatment or professional medical advice.
Pure CBD oil is not snake oil either. The research on CBD is growing and there is legitimate science behind how it interacts with the human endocannabinoid system. The key is buying a product that actually contains what it says it does, from a source you can trust.
Pure CBD oil is not something you should be buying from anonymous marketplace listings with no COAs, no company contact information, and suspiciously low prices. That is not a deal. That is a gamble with your health.
How to Buy Pure CBD Oil You Can Actually Trust
After twelve years in this industry, here is my straightforward advice.
Buy from a brand that publishes full third party lab results. Buy hemp that is USDA Certified Organic and grown in the United States. Look for CO2 extraction on the label or product page. Read the ingredient list and make sure it is short. Know who you are buying from and that there is a real person accountable for what is in the bottle.
When you buy Hempworx pure CBD oil through CBD Online, your order ships directly from Immunotec, the manufacturer. You are not buying from a reseller or a warehouse.

Pure CBD Oil — Frequently Asked Questions
What does pure CBD oil actually mean?
Pure CBD oil means the product contains CBD hemp extract in a clean carrier oil with no artificial fillers, synthetic additives, or unnecessary ingredients. It is not the same as CBD isolate. Both full spectrum and broad spectrum oils can be genuinely pure if the formula is clean and the sourcing is legitimate.
How can I tell if a CBD oil is actually pure?
Ask for the Certificate of Analysis from an independent lab. It should show you the CBD content, the full cannabinoid profile, THC levels, and test results for pesticides, heavy metals, and residual solvents. If the brand cannot produce one, do not buy it.
Is full spectrum CBD oil pure?
Yes, if it is made with quality hemp extract and a clean carrier oil. The presence of other natural cannabinoids and trace THC does not make it impure. Those are naturally occurring compounds from the hemp plant, not additives.
Does pure CBD oil have THC in it?
Full spectrum pure CBD oil contains trace amounts of THC under the legal limit of 0.3 percent. Broad spectrum pure CBD oil has the THC completely removed. Neither type will get you high.
How long does pure CBD oil take to work?
Most people notice results with consistent daily use over two to four weeks. Taking it sublingually under the tongue for 30 to 60 seconds gives you the fastest absorption. Give it a proper trial before you decide.
Can I use pure CBD oil with other wellness products?
Many of my customers combine Hempworx CBD oil with Immunocal glutathione as part of their daily routine. Always consult your healthcare provider if you take prescription medications, as CBD can interact with certain drugs.
Where can I buy pure CBD oil?
You can shop the full Hempworx range at CBD Online. Every product ships directly from Immunotec with a 30 day money back guarantee.
