If you are shopping for a CBD cream with no THC, the label words that matter most are broad spectrum, full spectrum and isolate. They describe what is left in the hemp extract after processing, and they decide whether THC can be in the jar at all. This guide explains each one in plain terms, what "0% THC" on a label actually means, and how to check that claim yourself on a certificate of analysis (COA) instead of taking a brand's word for it.
The short answer
- Full spectrum keeps the plant's full range of cannabinoids, including trace THC.
- Broad spectrum keeps several cannabinoids but has the THC removed.
- Isolate is CBD (cannabidiol) on its own, with the other hemp compounds removed.
So if you want a CBD cream with no THC, you are looking at broad spectrum or isolate, and then you are checking the lab report to confirm the THC result. The spectrum word on the front tells you the intent. The COA tells you what the batch actually tested at.
What "spectrum" means on a CBD label
Hemp makes more than one cannabinoid. CBD is usually the main one, but an extract can also carry smaller amounts of compounds such as CBG (cannabigerol), CBN (cannabinol), CBC (cannabichromene) and CBDV (cannabidivarin), along with THC (tetrahydrocannabinol), the compound associated with feeling high. Processors choose how much of that mix to keep. The spectrum term is shorthand for that choice.
Full spectrum
A full-spectrum extract is the least processed of the three. It keeps the cannabinoids the plant made, including whatever THC was present. Under the 2018 Farm Bill, hemp is defined as cannabis containing no more than 0.3 percent delta-9 THC on a dry-weight basis, so a full-spectrum hemp product is expected to contain some THC, just a small amount. If THC is something you need to avoid for any reason, full spectrum is the category to skip.
Broad spectrum
Broad spectrum starts from a fuller extract and then has the THC taken out, while keeping other cannabinoids in the mix. That makes it the middle option: more than CBD alone, without the THC. The quality of a broad-spectrum product depends on how well the THC removal worked, which is exactly why the lab report matters.
Isolate
Isolate is purified CBD, typically a white crystalline powder before it is blended into a product. Everything else from the plant is removed. Isolate products should contain no THC by design, but they also contain none of the other cannabinoids. Some people prefer that simplicity; others prefer broad spectrum because it keeps more of the plant's compounds.
Broad spectrum vs full spectrum vs isolate at a glance
| Full spectrum | Broad spectrum | Isolate | |
|---|---|---|---|
| CBD | Yes | Yes | Yes |
| Other cannabinoids (CBG, CBN, CBC and so on) | Yes | Yes | No |
| THC | Trace amounts expected | Removed; should test as not detected | Removed; should test as not detected |
| What to check on the COA | The THC figure, and that it sits within the hemp limit | THC reads "ND" (not detected) and other cannabinoids appear | THC reads "ND" and CBD is the main result |
What "0% THC" on a label actually means
No lab can prove a true zero. What a lab can say is that a compound was not detected above the smallest amount its method can reliably measure. On a COA you will see this written as ND, and the report lists the method's limit of detection (LOD) and limit of quantification (LOQ) next to each compound.
So when a brand prints "0% THC" or "THC free", the honest reading is: the batch was tested, and THC was not detected at the lab's limits. That is a meaningful, checkable claim, as long as the brand publishes the report. A "0% THC" label with no lab report behind it is just a sentence.
Two practical points follow from this:
- Look for the batch, not just the brand. A COA applies to the batch that was tested. A good brand tells you which batch the report covers, so you can match it to what you bought.
- Look at total THC, not one line. Labs report delta-9 THC and THCa (the acidic form) separately, then combine them into a "Total THC" figure. A product can look clean on one line and not on another, so read the total.
How to check a CBD cream's THC claim on its COA
You do not need a science background for this. Open the report and work through five things:
- Who tested it. The lab's name and accreditation (often ISO/IEC 17025) should be on the page. It should be a third party, not the brand.
- What was tested. The sample name should match the product, and ideally the batch number should match your jar.
- The THC rows. Find delta-9 THC, THCa and Total THC. For a broad-spectrum or isolate product you want "ND" across them.
- The other cannabinoids. If a product says broad spectrum, you should see more than CBD listed with a result. If only CBD shows up, it behaves like an isolate whatever the front label says.
- The date. A report from several years ago on a product that has been reformulated since tells you little.
If a brand will not show you a COA, or shows one that does not match the product name, consider the "no THC" claim unverified.
Why we chose broad spectrum and 0% THC
Melrose Relieve was developed by massage therapists for use in a working clinic, and that shaped the THC decision more than anything else. In a massage room, practitioners apply a balm to many different people in a week. Some of those clients work in jobs with workplace THC testing, some simply prefer to avoid THC, and some ask the question before they will let anything touch their skin. We wanted a product that could be handed to all of them without a second conversation.
Isolate would have solved the THC question too. We chose broad spectrum because it keeps more of the hemp plant's other cannabinoids in the extract while still testing with no THC detected. That is a preference about the formula, not a claim that one spectrum works better than another for any purpose.
Here is what the published report for the current batch shows. The cannabinoid analysis by SC Labs, linked from our lab results page, lists Total THC: Not Detected, with delta-9 THC, delta-8 THC and THCa each reported as ND. Alongside CBD, it reports measurable CBG, CBDV, CBN and CBC, which is what you would expect to see in a broad-spectrum extract. You can open the PDF and read every row yourself.
On the jar, the label states 2,000 mg CBD per oz in a 100 ml (3.38 fl oz) glass jar, and the product is labeled 0% THC. It is a waterless balm made in small batches, with no synthetic fragrance. If you want to compare strengths across brands, our guide to mg per oz vs mg per jar walks through the arithmetic.
A note on workplace testing
This is the reason many people search for a CBD cream with no THC, so it deserves a straight answer. No brand can promise you a particular result on a workplace test. Tests, cut-offs and policies differ, and the outcome depends on things no label can control. What you can do is reduce uncertainty: choose broad spectrum or isolate, insist on a batch-specific COA showing Total THC as not detected, and check your employer's policy before you start using any hemp product. If your job carries real consequences, ask your employer or occupational health provider first.
Other things worth checking while you are on the label
THC is one line on a long ingredient list. While you are reading, a few other details tell you a lot about a topical:
- Water content. Creams and lotions are mostly water, which dilutes the concentration and needs a preservative system. Waterless balms skip both. Our explainer on balm vs cream vs lotion covers the trade-offs.
- Fragrance. "Fragrance" or "parfum" can hide a long list of undisclosed ingredients. Named essential oils are easier to check against a known sensitivity.
- Sensitivities. Read the full list for anything you react to. Melrose Relieve contains beeswax, arrowroot powder and menthol crystals among its ingredients; the complete list is on the product page.

For practitioners stocking a no-THC topical
If you run a massage, chiropractic or physical therapy practice, the THC question will come from clients before almost any other. Keep the COA where you can show it, know which batch is on your shelf, and avoid promising anything about test results. We wrote a fuller checklist in what to ask a wholesale CBD supplier, and practitioner pricing is on our professional page.
Frequently asked questions
Is there such a thing as a CBD cream with no THC?
Yes. Broad-spectrum and isolate products are made with the THC removed. Look for a batch-specific lab report showing Total THC as "ND" (not detected) to confirm it.
What is the difference between broad spectrum and full spectrum CBD?
Full spectrum keeps all of the plant's cannabinoids, including trace THC. Broad spectrum keeps several cannabinoids but has the THC removed.
Is broad spectrum or isolate better?
Neither is better in general. Both should test with no THC detected. Broad spectrum keeps other cannabinoids such as CBG and CBN; isolate is CBD on its own. It comes down to preference.
Does "0% THC" mean there is absolutely no THC?
It means THC was not detected above the testing lab's detection limits for that batch. The COA lists those limits next to each compound, so you can see exactly what was measured.
Will a no-THC CBD cream affect a workplace test?
No brand can promise a test result, because tests and policies differ. Choose a product with a batch-specific COA showing Total THC as not detected, and check your employer's policy before using any hemp product.
Is Melrose Relieve broad spectrum?
Yes. It is broad spectrum and labeled 0% THC. The published SC Labs report lists Total THC as not detected, alongside measurable CBG, CBDV, CBN and CBC.
