Rick Simpson Oil (RSO) is a highly-concentrated form of marijuana oil developed by a Canadian engineer. Rick Simpson began cultivating his own cannabis and developed his own form of cannabis concentrate after being diagnosed with a form of skin cancer. He originally applied his cannabis concentrate topically on a bandage to treat his basal cell carcinoma. His Remedy later became known as RSO.

Rick Simpson Oil is highly potent with THC levels between 60-90%. Rick recommends his oil be produced with pure indica strains. Indica strains give RSO its sleep-inducing, sedative effects, which are key in the healing process.

It’s sometimes produced with hybrid strains, as long as they contain no more than 10% sativa. The crossing of indica and sativa strains create a hybrid with energizing side effects, counterproductive to the body’s healing process.
