The reason they will not state which oils is that because of FDA restrictions, they are NOT ALLOWED TO.  The key is what they said in the article, they can't find funding because the oils cannot be patented since they are naturally occurring compounds.  I'm a distributor for Young Living oils, and many oils have been found to have these properties, however, if we tell you what they are we can be shut down - even the entire company can be shut down.  They have threatened Young Living with complete shut down unless all distributors comply with not making any claims as to what specific oils can do until a battery of tests is run by people the FDA approves of (nevermind that they are mostly big pharma companies who will not do these studies because, again, they can't make money from something they can't patent).  There are people dying daily who could probably be saved if only the FDA did not have a strangle-hold on the process.  Meanwhile, they approve drugs (and even require certain drugs) that are known to cause cancer, cause major neurological and other problems, and even kill you.  Because those, my friends, make money.  The western medicine system is too caught up in the dollar to be willing to admit or reveal that the human body is interconnected and what impacts one part will impact all.  Drugs go into your bloodstream, therefore, your whole body is being effected when you introduce anything into your bloodstream.  I am ALL FOR people making money, but not at the expense of someone else being sick or dying because something that would end that suffering isn't profitable enough to do what is needed to get it to the public.  The FDA is the biggest problem, here, because it's pockets are interconnected with big pharma and they are both helping each other not let us know what will heal us.
