RSO, or Rick Simpson Oil, is named after a Canadian cancer patient turned cannabis activist. RSO is sometimes referred to as a “whole plant” or “full spectrum” extract because it retains the full cannabinoid, terpene, and chlorophyll profile of the source material by using specific solvents. – Euphurkle is a high CBD strain. If you are new to RSO, this would be a great way to ease into it without a highly intoxicating effect.
