More generally – the problem I have with the oil thing is they are a complex mix of chemicals. I am sure some of them have the potential to provide therapies for various conditions. Let’s do the studies and find out. Pharmaceutical companies are still looking at plants as sources of drugs (example: http:///blog/2014/06/28/is-big-pharma-ignoring-marijuana/ ). The idea that “Big Pharma” is somehow not interested or is trying to downplay the effectiveness is nonsense – because if there is potential to isolate something and make money – you better believe they will do it!
