RSO typically refers to Rick Simpson Oil, a potent, full-spectrum cannabis oil designed for medicinal use, created by Canadian activist Rick Simpson to manage his own health issues. This extract contains all the cannabinoids, terpenes, and flavonoids from the cannabis plant, which work together through the entourage effect to enhance its therapeutic potential for symptoms like chronic pain, anxiety, and nausea associated with cancer. RSO is administered orally or sublingually, or even topically for localized relief. THC 72 CBN 0 CBD 0 CBG 3 THCV 0
