ergggg I had a whole deal written out and lost it. So just let me say that I agree that an herbalist is usually more qualified to know what an herb or EO will/wont do, and what it affects, but they generally are not more qualified to know what or how medicines will interact (and some physicians dont know either). It really takes some eduction on the consumers part, which is why I feel it is important to label so that they know there could be issues. Most people think that EO's are just potent fragrances, so eduction is paramount.
Smoovie; I was not implying that you didn't understand about EO's. My "you" was a general "you". Since you were asking about warning labels, I assumed that you knew they were needed and for you to know that, you had to know about them. But many bath and body creators, especially the newer ones, do not think that EO's are anything more than strong scents, so my statement was geared toward those people and to that mind set.
As for your question, I still feel that your general warning is too general. While every pregnant woman should be cautious at all times, as someone said, all these companies cover their butts by printing warnings on everything, about everything. This tends to make people complacent, and if you didnt know any better, you would probably ignore that general warning without a second thought. Since some EO's really can impact our health in a negative way, I feel the more important issues should be spelled out. I save my (small space) warnings for the handful of EO's that have specific contraindications, the ones that are life-impacting. So if an EO will raise/lower BP, may cause spontaneous abortions or seizures, or accentuates any pain or relaxation medication, it gets labeled that way. I know this can be a spacial challenge, but I feel that it is more important than just the covering of behind.
