What is RSO? Rick Simpson Oil (RSO) is a concentrated cannabis extract known for its high potency and full-spectrum benefits. Developed for medicinal use, RSO is ideal for managing chronic pain, inflammation, and other conditions. American Cannabis's Rick Simpson Oil (RSO) is a potent, full-spectrum cannabis oil designed for versatile use and maximum relief. Packaged in a convenient 1-gram jar, it’s perfect for oral, topical, or edible applications. With a terpene profile featuring myrcene, limonene, caryophyllene, and pinene, this RSO provides a well-rounded experience, and ensures this potent indica oil won't take you out for the day. RSO is already known to be effective in pain management, but with high levels of CBG and CBC present in our strain, it’s especially effective for pain management, offering an alternative for those not fully aided by CBD-rich products.
