Rick Simpson Oil (RSO) is a type of concentrated cannabis oil named after Rick Simpson, who popularized the product. Simpson claims that he used the oil to cure his own skin cancer and has since advocated for its use in treating various ailments. The oil is highly potent, containing a high concentration of THC (tetrahydrocannabinol), the psychoactive component of cannabis, along with other cannabinoids. RSO is typically made using a solvent extraction process, where cannabis plant material is soaked in a solvent like ethanol or isopropyl alcohol to strip away the cannabinoids. The solvent is then evaporated, leaving behind the thick, tar-like oil. This oil is very potent and is usually administered in small doses. It's important to note that while there are anecdotal reports of RSO having anti-cancer properties and other health benefits, these claims are not widely supported by clinical research. Its legal status also varies by location, depending on cannabis laws. Always consult with healthcare providers for medical advice and check local regulations regarding cannabis products.
