Help put pain to bed. Soothe flare-ups faster than you can say 'SOS.' RSO is a concentrated and potent medical cannabis extract developed by Canadian medical cannabis activist Rick Simpson in 2003. Authentic RSO contains a full-spectrum of cannabinoids, terpenes and rich whole plant metabolites for potent medical cannabis relief. RSO can be applied as a topical, absorbed sublingually, or swallowed. For topical application, apply directly to the skin surface. For sublingual absorption, drop and hold under the tongue for at least 30 seconds. RSO can be mixed in food and drink for easier dosing. Doctor Solomon’s follows Rick Simpson’s published method with laboratory-grade quality control. We start by harvesting, trimming, and flash-freezing premium quality flower. Frozen flower is then extracted in a sub-zero ethanol base to improve purity. After extraction we filter out leftover plant matter and remove the ethanol. Finally, we use decarboxylation to activate phytocannabinoids.
