Rick Simpson Oil (RSO)
Rick Simpson Oil (RSO) is a alternative, unapproved, or historically promoted cancer therapy promoted by some clinics, authors, practitioners, or patient communities as an anticancer treatment, immune strategy, detoxification method, or substitute for conventional care. In cancer care, it should be evaluated by evidence level, intended use, safety, interactions, and whether it is being used as conventional treatment.
