There are three forms of CBD oil you might come across, full-spectrum CBD, broad-spectrum CBD and CBD isolate. Basically all CBD on the market is extracted from hemp plant flowers.
The difference in these three forms lies in the amount of refining that goes into each of them.
Full Spectrum CBD Oil – This is the least processed form of CBD available. This form refers to the raw oil extracted off the hemp flower. It contains a range of naturally occurring cannabinoids, terpenes and plant molecules.
Broad Spectrum CBD Oil – This is a refined version of the full spectrum which has a few cannabinoids left but no terpenes or other plant molecules. Typically there will be no THC left in a broad spectrum extract. It will be primarily CBD with very small amounts of some other cannabinoids.
CBD Isolate – This is the most refined version of them all. Further refining down the extracted oil to the pure CBD molecule.
Unfortunately, New Zealand’s definition of a CBD product only allows for broad-spectrum and CBD isolate, as full spectrum contains too much THC.
The hemp plant naturally produces an oil containing between approximately 20-30 times more CBD than THC. In order to meet the definition of a CBD product in New Zealand, the oil is required to have 50 times or more CBD than THC which does not occur naturally in the plant.
To meet this requirement, the raw oil has to be refined to remove the THC which unfortunately also removes other cannabinoids and terpenes.
Even though a full spectrum product with a range of cannabinoids is regarded as a superior product,
