Nature’s Concentrates S-Oil is our exclusive fully decarboxylated version of RSO (Rick Simpson Oil). Our unique recipe activates all the available THC. Thus we have trademarked the Nature’s Concentrates version simply as “S-Oil.” Our S-Oil is made using a blend of handpicked shatter oils that are combined to be fully cooked (decarboxylated) allowing the oil to be ingested rather than smoked or vaporized.
