make sure you can take what you are internally!

some e.o. can not be taken internally.

you want to look for tinctures. i get my tinctures here:

http://www.herb-pharm.com/catalog

they are all organic and shade dried.
they smell and feel very fresh. they come in a dark amber glass bottles with a glass dropper too so no plastic chemicals leech into the tincture.

also with whatever you use, google side effects and overdose signs so you know if you should stop taking whatever you are. and never take Wormwood or anything if you are pregnant. your body will abort the baby.
