I need to know if BHO and RSO are interchangeable as far as anti-cancer properties. I am recently diagnosed with lung cancer and have been given medicinal grade BHO. I have ingested some small doses by mouth and it does have an effect so I know it's getting into my bloodstream. My question; For anti-cancer use, do I need to further refine the BHO into RSO or is it fine as is for oral use.
