List: I found the following commentary posted on Quackwatch about the aroma 
therapy article. Roger

Thirteen per cent decrease!  Wow I'm really not impressed especially when
the endpoint is something as subjective as behavior.  This is not even up to
snuff for a placebo effect. One doesn't have to read the actual report to
realize that the control group, if there was one, was not blinded. What
about the toxic effects of these oils? Has anyone rubbed lavender or
sandalwood oil on rats before trying it out on granny?
