Rick Simpson Oil – RSO

Rick Simpson Oil, called RSO for short, is one of the most versatile and lauded cannabis innovations—an oil created by Rick Simpson, a Canadian engineer and cannabis advocate who was radicalized to cannabis activism by a work accident that led to various health issues.
The story goes that he was able to resolve his health issues with RSO, a dark, tar-like cannabis extract that straddles the line of concentrate, edible, and topical. In short: There’s very little it can’t do, and a lot it can do for both patients and stoners.
Put simply, RSO is an oil derived from cannabis. But rather than a solvent extract that strips trichomes from buds, RSO contains all the cannabinoids, terpenes, and additional compounds of the whole cannabis plant.
The extraction process is complex and fairly long, similar to making a tincture. It’s typically near-black in color, and, admittedly, doesn’t taste great due to its high amount of plant matter (it uses the whole plant).
