RSO, Rick Simpson Oil (also known as Phoenix Tears), is a highly concentrated, full-spectrum cannabis oil originally developed by Canadian medical cannabis advocate Rick Simpson. Simpson created the oil to treat his basal cell carcinoma and, eventually, for others with various health conditions, spanning from cancer to respiratory symptoms. Simpson eventually stopped making the oil himself and put the tincture-like extraction process online for others to make. The process can be complex, and many consumers prefer to purchase RSO from a dispensary. 

Unlike typical extracts, RSO preserves the full cannabinoid and terpene profile of the cannabis plant, delivering a potent dose of THC and other therapeutic compounds in every drop. This thick, dark oil is known for its intense medicinal strength and is widely used by individuals managing chronic pain, cancer-related symptoms, inflammation, and other severe or debilitating conditions. Each 1g syringe is filled with pure, potent oil that can be ingested, used topically, added to edibles, or even used in refillable cartridges (for those familiar with that method).

RSO is not intended for recreational use — it’s designed as a therapeutic option for those seeking serious, plant-based relief. Its full-spectrum composition makes it one of the most respected and sought-after concentrates in medical cannabis care.

How to Use: Start with a very small dose (about the size of a grain of rice) and gradually increase as needed. Can be taken orally, mixed with food, or applied topically. START LOW AND GO SLOW. You can always take more, LATER. Give yourself time for the dose to take effect!
