Rick Simpson Oil (RSO) is a highly potent, viscous, dark-brown/black oil. RSO results from stripping the cannabis plant’s trichomes, which are rich in therapeutic cannabinoids and terpenes. The final product is a powerhouse of healing compounds, including potent tetrahydrocannabinol (THC). Created by a Canadian scientist named Rick Simpson, RSO originally helped its namesake treat an aggressive form of skin cancer. Simpson was diagnosed with basal cell carcinoma and delved into research on the impact of THC on cancer cells. From there, he created a cannabis oil that he applied to his skin. After only four days, his cancerous cells were reportedly gone. Sold on the healing effects of medical marijuana, Simpson cultivated his own cannabis, harvested his own plants, and created more cannabis-infused oil, known today as RSO.
