truth in advertising

Ugh.  I saw some candles today that clearly stated, " pure essential oils in  soy wax" that was labeled as an aromatherapy candle and had some nice verbiage on the back about the benefits of the essentials oils supposedly in the candles.  I opened the box and bam!  synthetic fragrance filled my lungs and eyes.  Evidently there must be some essential oils in there somewhere but there was also lots of sickening, overpowering, synthetic fragrance also.   Where is the truth in advertising?  Who is regulating this?  Obviously no one.  How sad.  By all outward accounts, these candles appeared to be 100% natural, plant based candles with JUST essential oils.  What kind of aromatherapy is it if it kills you?  I was sad to see this (I see it a lot but usually the labels say "with essential oils" or "essential oil blend", still deceiving but, I now know these deceiving terms and look for them).  Of course, I can tell right away by smelling a candle whether it is real or not.  Can you?  I would love to here if others can tell, or if they think that maybe they are just allergic to certain flowers or the scent is to strong and that is what is bothering them rather than thinking that a company is deceiving them.
