Common CBD terms explained
Batch number
A code used to identify a specific production run. It matters because a useful lab report should correspond to the same batch or lot shown on the product.
Broad-spectrum
A type of CBD extract positioned between full-spectrum and isolate. It is usually described as offering a broader hemp profile than isolate while taking a more cautious approach to THC than full-spectrum products. See the full spectrum comparison for more context.
Carrier oil
The oil used to dilute and deliver the hemp extract in a tincture. Common examples include MCT oil, hemp seed oil, and olive oil. Carrier oil can affect texture, flavor, and ingredient preference.
CBD
Short for cannabidiol, a compound commonly associated with hemp. On this site, CBD is discussed in the context of product labels, buying considerations, and general consumer education rather than medical claims.
Certificate of analysis (COA)
A third-party lab document that reports information about a product batch, often including cannabinoid content and certain screening panels. The lab report guide explains how to use one.
Full-spectrum
A label typically used for products that retain a broader hemp profile. It does not automatically indicate better quality, but it does signal a different type of formula than isolate or many THC-free products.
Hemp extract
The concentrated material derived from hemp that provides the product's cannabinoid content. Different extraction and refinement choices can lead to full-spectrum, broad-spectrum, or isolate-style products.
Isolate
A more narrowly defined CBD ingredient centered on purified cannabidiol. Isolate products are often chosen by readers who want a simpler ingredient profile.
Milligrams (mg)
The unit most commonly used to describe how much CBD is in a bottle or serving. Comparing milligrams only makes sense when you also understand bottle size and serving information, which is why the strength guide matters.
Potency or strength
Informal ways of describing CBD concentration. These terms are only useful when backed by actual numbers such as total CBD content and bottle size.
Spectrum
A label category describing how broad or narrow the hemp extract profile is intended to be. The three most common labels are full-spectrum, broad-spectrum, and isolate.
Third-party testing
Testing performed by an independent laboratory rather than the brand itself. For buyers, it is one of the clearest ways to move beyond packaging claims.
THC-free
A product positioning used for formulas designed to avoid THC in the finished product. Readers who prioritize this category may want to start with the THC-free CBD oil guide.
