Cannabis extract medicine has been used for generations to help treat a variety of conditions, and its popularity has increased quite a bit in recent years. Much of this increased popularity can be traced to Rick Simpson‘s public campaign in favor of what he referred to as “hemp oil.”
“Ethanol and olive oil were determined to be the most effective, largely because of their ability to produce an extract with a high terpene content. Perhaps more importantly, both substances are safe for consumption.”
Last year, a group of researchers from the University of Siena (Italy) and Leiden University (Netherlands) completed a study comparing some of the most commonly used extraction solvents. Their results were published in the journal Cannabinoids.
