Extraction of CBD oil can be done in three different ways:
Pushing C02 through the plant simultaneously at high pressures and low temperatures, CBD oil can be extracted in its purest form. This process is often thought of as the best and safest as it cleanly extracts CBD, removing substance like chlorophyll and leaving no residue. CBD oil extracted in this way has a cleaner taste, but it is a more expensive method than other alternatives.
CBD oil can be extracted using high-grain alcohol. However, this method destroys some of the beneficial natural oils which come as a byproduct.
This method of how to make CBD oil is growing in popularity. The method involves extraction using a carrier oil. Olive oil is most commonly used in this process. The rise in popularity of this method is due to the added benefits of the nutrients in the oil used and the fact that it is safe and free of unwanted residues.
