Never really heard of those no - there was one type i wanted to do with a therapist online but was unable to do so because we couldn't get my insurance to cover him but i haven't been able to find any that do that type since and i had never heard of it before - i will have to look it up again.

Lavender is awesome for sleep, anxiety, migraines and many other ailments as well - the rose is very good for the depression. I am sure you will be happy with that combination. Even at the whole food stores though you have to check the therapeutic grades because not all brands are as reputable as other brands - and some like to try to mix things in in order to sell it as a "blend" or etc, others just water it down and/or add a bunch of additives - so just be sure to check the label. If you aren't sure someone at the store should be able to assist you.
