// Definition
A concentrated whole-plant cannabis extract made by soaking cannabis in a solvent (typically naphtha or isopropyl alcohol) and evaporating the solvent to leave a thick, dark oil. Named after Rick Simpson who popularized it for cancer treatment, though the term has become generic for any concentrated cannabis oil used medicinally.
// From the Episode
Bubbleman referenced Rick Simpson Oil in the context of discussing different medicinal cannabis preparations. He noted that RSO is merely one form of concentrated cannabis medicine and that the benefits extend beyond any single preparation method. The panel discussed how patients need education about the various forms of cannabis medicine available and that no single extraction method is universally best.
