Good points LoneOak , your again correct . Many medical treatment are evasive & incure an element of risk & potential side effects . Not something you want to deliberately expose yourself to . Coumadin ( warfarin) used for yrs to control thrombosis ( blood clots) is now considered a Carcinogenic agent . Anyhow there are numerous physical & chemical agents that have the potential for Carcinogenic / Mutgenic (DNA changes) / Terotegenic ( fetal effects ) on humans . Let alone environmental impacts . Many environmental studies eventually include the Toxiclogical & biological route of entry components , Inhalation , Absorbtion & Injestion for a reason . I appreciate the benefits of a good oil application , however not at the risk to health or the environment . Thanks for your imput brother !
