RSO is an abbreviation for Rick Simpson oil. It is a cannabis concentrate that is made pretty easily at home, using food grade alcohol to strip cannabis of its medicinal properties. I used everclear, and let the de carbed cannabis and alcohol mixture ferment for 3 weeks. Upon straining the cannabis out of the alocohol I was left with “green dragon”. Green dragon is cannabis tincture.. it is high in alcohol content, but also high in medicinal properties from the cannabis. If you don’t want the alcohol, you can remove it, and that’s when you are left with rso. This can be used as a topical, to cook with, or placed right on your tongue for fast medication delivery. Cheers everyone! Sorry I don’t have any pictures of the green dragon being poured into the dish... but I did take some pics of the green dragon after the alcohol had evaporated. Pictured is my rso!
